We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Tools, Infrastructure & Documentation

Syscoin Bridge

Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20
A two-way blockchain interoperability system that uses Simple Payment Verification to enable:
  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

HOWTO: Setup an Agent
Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)
Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

COSS Exchange and COSS Token - A Full Summary

Let me get started by stating I am no way involved with the COSS team. I simply am a COSS holder who wants to share this coin with others. Please note, I am writing this without an opinion and just stating facts (I will include a portion below with my opinions and an explanation of my thought process). Everything I say can be double checked with some DD and if I have time, I will come back and link said facts!
What is COSS?
What does COSS do?
What is the payout formula?
When are payouts?
How do you receive payouts?
What is the total supply?
What is the current marketcap?
Where can I buy COSS?
My opinions:
1) COSS, based on numbers, is simply undervalued. For a token that already has an existing functional product, its marketcap is well below what it should be. Trading volume has also increased significantly in the past few days! Imagine receiving profits from an exchange like Bittrex or Binance I urge you to browse their website and look at everything for yourself to make your own judgement!
2) There is a lot of work to be done on the exchange, but it is just getting started and is still in Beta. Good things take time. I remember when Binance first began and the struggles it went through, and look at it now. I have faith COSS can do that same. Currently, the things I believe that need to be fixed are exchange UI upgrades to make them more appealing to the eye and deposit/withdrawal times.
3) There is a lot of concern about COSS being a scam due to the team's association with VRS. I definitely had to look into this and found that Rune, on of the founders, addressed this concern. For me it was a satifactory explantion stating that VRS was not a scam, but a failed project. Please read bullet 4 to get the link to the full statement and other FAQ's
4) There are tons of FAQ's and known issues that are being asked about COSS. These two links pretty much cover them all at the moment. Each link has some different information, so please read both!
FAQ - 1 https://www.reddit.com/COSS/comments/74pw7h/all_info_to_clear_up_confusion/?st=j8gjl9jz&sh=b777583e

Humans help the Andalites... Again. Ch.1

The war against the Yeerks was over, both the Andalites and Humans races enjoyed a time of blossoming peace, trade, and prosperity. The Humans faired well in the aftermath of the war, Earth being spared mass commitment or damage, and little loss of life. The Andalites were advanced, but weakened, from the long war against the now defeated and subjugated parasitic slug-like race of Yeerks. The part deer, part scorpion, part human looking Andalite race was slowly recovering from the war and wearily exploring new opportunities for trade with its new "friend", the Humans.
The Andalites are a powerful race, with some of the best technology in their explored corner of the galaxy. A warrior species at heart, Andalites are well developed for combat, with 4 eyes, 2 of those eyes on bendable stalks, 4 strong legs, a deadly fast tail with a scorpion blade, and a bright mind. Though fairly gentle hearted by nature, the Andalite's 100 million or so members nonetheless appreciate the role of the warrior more than almost anything, other than maybe family, being that they live in close knitted groups in their outdoor homes called "scoops".
The Andalites were fairly proud race, and some may call them arrogant about their abilities, technology and their species. They did not think all that much of the Human race and what they could bring to the table, and were naturally suspicious due to the Yeerks betrayal of the Andalites in the past. The Humans, however, proved themselves to be very able at waging war, with a paltry 5 human teenagers and 1 Andalites cadet managing to topple the powerful Yeerk empire with well-timed guerrilla attacks and smart thinking, combined with illegally gifted Andalite morphing technology from the war-price Andalite hero Elfangor.
The Human race lost approximately 90,000 souls from the Yeerk infiltration of Earth. The slug-like Yeerks, who takes over their host's brains and bodies, can perfectly mimic a person and use their memories and brains to help them do so. Thousands of people were killed by their controlling Yeerks who rathered go out fighting then be starved to death from lack of their precious Kandrona rays generators. While few Humans were killed during the actual "war", there were some deaths from the Animorphs guerrilla fighters vs infested humans and free Human vs Yeerk forces. Tens of thousands of civilians were also killed during suicidal bombing attacks on Yeerk infestation centers by the small teenaged Human guerrilla force and their Andalite companion.
The Humans proved themselves to be tenacious, determined, adaptive, quick learning, and good in a fight. Surprising everyone, the Human race managed to beat back an invasion from a species most Humans had no idea existed. Humans did not just beat back the invasion, they managed to take over a pool ship, and transferred its command codes to the Andalite, allowing them to snap up a major yeerk fleet and the Yeerks top ranking general. With the Yeerk high command in turmoil, their top generals all dead or captured due to Humans, and in some cases civil-war between other yeerks, the Andalites were able to use the stolen Yeerk command data and a promise of morphing out of their bodies to subdue the Yeerks and blockade their homeworlds.
Humans were new to the galactic scene, but already were making waves, Human body morph permissions and foodcourt establishments on the Andalite homeworld promised Humans a big bargaining chip in trade with the Andalites. The Andalites did not have mouths themselves but could morph to human to experience taste, and it was becoming a booming trade, helping secure technology transfer deals to the Humans benefit. The technology transfers were coming somewhat slowly, but, Humans were already making giant leaps and their first faster than light spaceship was already under construction. Humans also reversed engineered some captured yeerk technology, circumventing the Andalites refusal to trade weapons tech.
The Andilites were somewhat wary of the Humans, while most Andalite civilians loved that Humans and Andalite cooperate well together and wanted good relations, Andalite command was less warm to the upstart and primitive race of humans. Andalites viewed human technology to be laughable, with every piece of human tech shocking Andalites with how old school it is, how dangerous it is, or how Humans even managed to get that far yet. Andalites high command viewed Humans as unpredictable, self-serving, primitive, and very weak looking creatures. Humans only had 2 legs, and 2 eyes, and looked as if they could barely stand up, lacking any tail! Humans were helplessly weak and had no real advantage to their bodies, the only reason yereks even wanted Humans was that they were too weak to resist, had fairly good senses and hands to handles technology, and had a supermassive 6 billion hosts bodies available. The one thing Andalite command hated the most about Humans, however, was that they could be competition.
Humans, as stated before, are in a laughably primitive state compared to Andalites or any other spare fairing civilization, such as the Skirt-Naa or the Leer. Most Andalites would be surprised to learn that a Human even knew about black holes. Most Andalite would be surprised that Humans invented books before the computer, as if the idea of powerless instantly accessible data was simple to think of. Most Andalites would be surprised to learn that Humans went from their first flight, to their moon, in just 60 years, 3 times faster than the Andalites. And most Andalites would be a bit nervous, more so than surprised, to find out that Humans went from having a man walk on their moon to discovering and inventing a Zero-space faster than light communication device in 50 years, right around the middle of the invasion of Earth by the yeerks.
The Human race works well with Andalites, both feeling a kindred with one another easily. Even before the invasion of Earth, a pair of teenage Humans would frequently surprise the to-be War price Elfangor when he was a cadet. Elfangor would be constantly surprised at how the soft, weak, and unsteady looking human body could take an amazing amount of punishment and still recover. and could be surprisingly strong and capable with their powerful and well-adapted arms and hands. Even the Humans unstable-looking 2 legs could be rather effective in giving the Human mobility in terms of running, jumping, and dodging. The young Elfangor found that both of his Human charges, kidnapped from their home planet, were rather determined. In fact, both of them had a key part to play in setting the stage for the eventual invasion of Earth. One for good, and one for evil. Truth be told, chances are the yeerks would have come either way, but, even 2 Human teenagers can have a huge impact on the galaxy many years down the road.
Peace now reigned, but it was to be short-lived, the Kelbrid bordered Andalite space, and may have killed an Andalite prince and former Animorph. Prince Aximilli, Elfangors younger brother, had survived the war on earth as a cadet and sole Andalite on the Animorphs team, and sole Andalite on earth, in general, most of the time. As a new prince and war hero, "Ax" was given the task of hunting down a rouge Yeerk force in a powerful "blade-ship" class cruiser. Ax's Andalites cruiser broke a treaty to stay out of each others space that was brokered with the Kelbrid, and after entering Kelbrid space Ax's cruiser was inspecting a craft it found via boarding party when the ship opened fire on Ax's vessel. Ax's ship had no choice but to run, and was subject to further attack, with only 1 survivor saved to tell the tale of Ax's capture on the strange ship they encountered during the search for the Blade ship.
The Andalite could not risk a war by entering Keldbrid space, even though they knew their hero was likely captured on a potentially Kelbrid ship. With 1 primary Animorph in addition to all the handicapped child auxiliary Animorphs killed, due to various suicide attacks at the end of the Yeerk war, 3 out of the 4 remaining Animorphs go on a mission to save their friend Ax, and all of them, the 3 rescuers and Ax, are killed in a suicide attack by the would-be rescuers, after learning their friend Ax was twisted into an abomination of a new sort, and that they were outclassed and under-prepared. The last known transmission from the Animorphs leader on the rescue mission was, "Ram the blade ship." There is only one confirmed Animorph left alive from the over 20 prime and auxiliary Animorphs during the war with the Yeerks, the intuitive tree hugger, Cassie. All known Animorph deaths have occurred due to suicide attacks, with the exception of one, and the possible exception of a second, (depending on if a suicide wish was granted to ease an evil traitor Animorphs pain of being stuck in rat morph to his arch-rival Animorphs who hovered on the edge of good and going too far down the path of becoming a monster herself. Nobody knows if she granted his death wish.)
With all known Animorphs dead, save for 1, and the Andalite war prince Ax believed dead, tensions rise in the command rooms for both Andalites and Humans, especially for the Andalites, who territorial space bordered the Kelbrid. The mission to rescue Aximilli lost Humanity its best heroes, and the Andalites lost their greatest war hero for good this time, the little brother of war-prince Elfangor was dead, as was almost the entire Animorphs team. Even Arborn, a fellow cadet and friend of Elfangor who was trapped in Taxxon morph, was dead, shot by a poacher on earth, after the war with the Yeerks ended. All the heroes who beat back the Yeerk invastion of the galaxy, with the exception of the tree hugger Cassie, were now dead, and not even the powerful time warping Ellimist would be able to bring them back this time, not being allowed in his comic game of chess to do them any other favors. The Andalites now had to worry about the fallout of the incursions into Kelbrid space, and both races would have to explain their Heros mysterious disappearances to its people using lies and tall tales.
As the Andalites desperately tried to predict what the Keldbrid race would do next, Humans continued to advance into making the transition to a galactic civilization. The moon was colonized with bases, thousands of humans now lived there in science and military outposts. Humanity continued to advance, the first "Zero Space" was launched, a second and third launched a few months later. With new each ship made, Humans modified, optimized, and resigned them to be better, faster, and more spaceworthy. Weapons on human spacecraft were still unheard of, but Human leadership was planning on adding those soon, the Human-modified dracon beams taken from the defeated yeerks being renamed "phasers" and given better damage and longer burst rates thanks to Human ingenuity. As the Andalites became to scan their borders fervently, Humans began to learn the art of weaponizing their space-ships with laser weaponry and began exploring captured shield tech and learning how it worked.
Years past, Andalite and Humans are rarely found in each other territory anymore. The Andalites have become recluse, nobody knows why, but they claim its to protect their species identity in these news times of species to species contact. The Humans and Andalites were working together on various business and governmental endeavors when suddenly, the Andalite high command issued orders to cease most contact with Humans, citing cultural identity concerns and the need to slow down and take more time to build trust. Humans were confused, the Andalite military folks could be a bit arrogant, but, Andalites and Humans got on pretty well, and Humans did not understand the sudden pullback in Andalite policy. Secretly, despite all the talk about "trust", Humans began to spy. They wanted to know what exactly was going on with the Andalites, and it did not help for Human leadership to secretly know that Andalite high command was planning on glassing planet Earth in a scorched earth policy during the war to stop the yeerks, and only reluctantly change gears after the Animorphs handed them a whole Yeerk fleet and the top general of the Yeerks.
The Andalites grew more distant, and Humanity watched from afar, using their secret Z-space telescopes to spy on Andalites planets and military movements. The Andalites were not an expansive race, having little desire to conquer new land, they only had 3 planets under their control. 20 years after the war with the yeerks, Humans were in the middle of terraforming Mars, and the moon was a full-fledged base of Humanity, with over 100,000 souls living there in domes and enclosed buildings. Humans had no real military space force, but the moon did contain powerful plasma turrets on its surface, with enough fire-power in its somewhat primitive model to surprise the Andalites, had they bothered to keep tabs anymore. The Andalites knew about the plasma turrets of course, but they did not care too much to check them out, and assumed humans had no real ability other than fighting wars limited to their own planet, and only shadow-based wars at that, believing humans to be unable to stand up to an advanced force of any kind with real numbers supporting them. The Andalites were occupied with something... Else... And Human leadership wanted to know what.
Andalite fleet movement had been detected by Human Z-space spy telescopes, lots of it, and Human leadership knew what it must be... War. They were not sure who the Andalites were gearing up to fight, but, Human leadership suspected it was the Kelbrid, knowing of the secret missions Andalites had taking place in their territory. The Kelbrid were considered to be advanced, powerful, and savage, but were known to keep their agreements, they would likely be very angry about their borders being intruded by Andalites after the agreement they made to stay out of each other's way. The Human leadership know what the signs pointed to, Humans had spent its whole existence fighting and killing, and it knew a fight brewing when it saw one. Humans made upgrades to their z-space spy scopes to take a better look at Andalite territory, what they found, was scary, if not surprising. The Andalites were indeed at war, and losing, badly.
The Andalites were in a panic, one of their worlds was burning, millions of Andalites dead, and the whole system it resided in was lost. The Andalites lost nearly half their fleet in trying to save their third planet and newest acquisition. After downsizing their military only 20 years ago, the newest generation of Andalites was tapped for war and hundreds of new ships were built at a frantic pace. The Andalite cadets knew what was expected of them.
Humans watched the development with great interest, they saw the third planet of the Andalites, Teeassic, burn. None seemed to be left alive, and the fleet around its orbit was devested. Humans watched as the Andalites pulled back to their remaining 2 planets, and build new more defense platforms to ring them. The Kelbrid were clearly a powerful foe, their ships massive in size, though old, and having massive firepower and defense shielding on their ships. Even the mighty Andalites dome ships, with shedder lasers that could punch a hole in a moon, were hard-pressed to stop even 1 Kelbrid battlecruiser. Humans watched as the Kelbrid matched the Andalites with 1 capital ship for every 3 of the Andalites own. The Andalites, while powerful, had clearly met their match, the Kelbrid was stronger than the yeerks and could push the Andalites back with their fierceness. Andalites, however, are brave to the point of ridiculousness, much like Humans, and the Andalites did not hesitate to self-sacrifice to attempt to win the war. Out of honor for their people, the Andalites forces again and again committed themselves to suicide attacks, fights that led to the self-destruction of the vessel they resided on, and just generally INSANE acts of heroism to try to stop the Kelbrid. But it was not enough, and the Andalites found themselves pushed out of open space and huddled around their 2 remaining planets.
All this time, the Andalites pretended nothing was wrong to the Humans. Civilian contact was cut off years ago, and Andalite military command, that acted as the species overall government more often than not, would send less frequent ambassadors, who nonetheless insisted everything was "fine" and the Andalite just wanted to take things slowly with Humans. For a time, Human leadership, consisting of the semi-centralized new earth government, took them at face value but grew less and less accepting of the excuses over time. The Humans did not want to admit to spying, but, it was a non-invasive long-range visual observation method, using holes in space-time, so they did not feel too ashamed of themselves for admitting it. Besides, the Andalites were losing and clearly needed help, badly. After witnessing a failed but close contested attack on the Andalites second planet, Luaminoa, Humans knew the Andalites were risking destruction and felt compelled to do something and say something.
Planet: Earth Year: 2022 Ambassador to the Andalites office, Washington D.C.
An old, haggard-looking Andalite of 160 years walks through the tall and wide door to the Ambassador's office, finding their species could not properly sit down like humans, a comfortable carpet would make due instead of a chair for the Andalite ambassador. The Andalite faces a middle-aged human of 40 years old, the blue-furred Andalite looks at the Human man standing before him, a man with bright blue clears eyes and a smile but sad smile on his face.
"Hello ambassador Theor-Getil-Illii", says the Human, using the Andalites full name rather then the shortened version. The Human did not shake the Andalites hand, knowing they are more fragile appendages than the ones Humans have. , said the Andalite telepathically, with a modest bow of its stalk-eyed head and human-like torso. , asked the Andalite. The small smiled faded off the Human ambassador's face, and in its wake was just sadness. "Theor", using the Andalites shorten named, "What is happening to your people?" The Andalite paused for a moment, seemed slightly taken aback, and responded. "Yes you do", the Human ambassador responded. "Your people are at war, and you are losing". The Andalites 4 eyes, trained on the Human, got big and his body tensed. The Human, not waiting for a response, continued. "We know you are down to 2 of your planets and are in a defensive position around their orbits, and we know about the Kelbrid and what is going on." The Andalite looked at ambassador Paul, and after a moment, asked,
the Andalite asked incredulously. "Well..." said the Human. "They really are more like micro cameras that look through micro holes in Z-space.", the Human explained. "Using just a tiny amount of energy, we can create a high-speed tunnel through Z-space, with nothing in the tunnel but a simple stream of quarks. The force of those quark streams keeps a small rift open that we peak inside of using a tiny camera that picks up on photons that enter the Z-space hole created as the quarks squeeze out of it.", the Human lectured. "This allows us to send tiny mass through Z-space at extremely high speeds, allowing for near-instant observation at the end of the tunnel created by the mass exiting Z-space at the target observation area." Shocked, Theor-Getil-Illii simply started at the Human, for a long time. The Human waited, and after a time, the Andalite seemed to find his thought-speak voice. , the Andalite babbled. , said the Andalite, trying to sound calm.
The old Andalite ambassador read Aximillis report, but could hardly believe it, let alone allow its impact to truly wash over him. However, the truth of Human now started to dawn him, and his body grew cold as his smart mind did the calculations and he thought to himself. The Andalite looked again at the Human, , the Andalite said slowly and half-mindedly> The Human nooded, understanding how the Andalite must feel, "Yes, we know we are the type to advance quickly compared to the most races we have learned of, it's just in our nature.", the Human said slightly sadly, "We just hope for the best", Paul said. Looking at the quite Andalite, Paul said, "Now, have you considered asking us for help? We would be willing to aid you, freely." Theor took a moment to think about that statement, before responding, Theor-Getil-Illii replied, borrowing the Human phrase to express a problem.
, Theor asked while taking a deep breath. "Certainly", said Paul. Theor started. Theor continued. Theor finished off. Theor said in thought-speak. Theor bristled. , ended the Andalite firmly. The Human ambassador looked on, knowing this would be a tough job, but one he would have to do.
"What if we offered you a million soldiers right now?" Paul asked. "Well trained, and we could even provide weaponry and supplies for them." Paul looked at the old Andalite. "We could even give you 3 million soldiers, armed and with some armored support, within 3 months time," Paul said. "China has already agreed to give a million soldiers today on the spot, and the United States and its alliances can provide 2 million after we formalize things a bit," Paul explained. "You could station them on Luaminoa, to use in defense in case of a troop based invasion.", Paul finished. The old Andalite stared, thought briefly, and said, Ambassador Paul nodded, but countered, "But you could still use the help when they try to take the planet as their own by troop invasion.", he said plainly. The Andalite ambassador countered, "Your people would all die." Ambassador Paul looked Theor in his 2 main eyes on his head, and said, "Yes, we know, but we are willing to do it to help you anyway. Out of friendship between the kin we know we have between our races.
The Andalite ambassador stood there that night, attempting to fall asleep in the middle of a moon-lit grass field, isolated and protected by security agents from the worlds cooperative governments for official Andalite guests to sleep in. No deal with struck today, just talk, the Andalite asked for an early recess to think and contact Andalite command. Theor-Getil-Illii would have preferred a tree to sleep by, in the half-asleep trance manner his forest and plains based species were accustomed to. The open field would have to do, however, not that his mind was letting him sleep. <3 million soldiers, in less than 3 months time?", he wondered to himself. The entire Andalite military force consisted of about 18 million Andalites, and that is even after the addition of female soldiers and higher than normal recruiting. A huge portion of the Andalite population was involved in the military in some way. It was like that in the time of the Yeerks, but now even more so, as the Kelbrid was a terrible enemy, and were using the entrance of 2 ships of Andalite belonging as a reason to continue to ignore any peace treaty and keep on the attack. Andalites understood their anger but believed this war to be a vast overreaction on the part of the Kelbrid.
3 million soldiers, the Andalite ambassador thought to himself, as he drifted off to sleep. It would be enough to nearly double the ground forces on their second world. It was a tempting offer, if the reports of humans being good ground-based soldiers were true. Allegedly Humans were tenacious ground-based combatants, who would not give up a fight easily and would use strategy and tactics as well as a wide variety of primitive but effective weaponry. Theor did the math, <3 million soldiers, out of over 6 billion people. That leaves them with 5 billion 997 million left, bare minimum.> Theor let the shock of that information wash over him. 3 million soldiers is a lot to Andalites sensibilities, and since yeerks were dependent on host bodies to do anything, it was a lot to the yeerks also. But to Humans, 3 million soldiers was a drop in the bucket, as Humans say it. It barely took a scratch out of their numbers. , the old Andalite thought to himself as he fell asleep. Humans had a vast population, and could make for very effective military use, should they be able to use weapons and have good mobility and senses. And they were primitive, vastly outmatched by all the other races in terms of technology, and bodies that could little to no damage to most creatures as well. And yet, somehow, Human minors, with the ability to morph from the Andalite Elfangor, were able to adapt and engineer the defeat of the Yeerks through guerrilla warfare. Theor-Getil-Illii slept while still pondering what to do about the Humans offer of soldiers and aid...

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.
Core Features:
  • Multi-Device – Ability to hide accounts from all but the primary account.
  • Multi-Account – Multiple, entirely separate accounts in one wallet.
  • Multi-Platform – Available on iOS, Android, Web, Windows, Linux and Mac OS
  • Multi-Signature – Create multi-signature accounts between many people, where a certain amount of people’s signatures is required to sign a transaction. Some can be required before a transaction is signed.
  • Native support for many currencies – Multiple currencies are supported, accessed all from the same wallet and backup keywords.
  • Advanced Coin Control (Choose which UTXO are involved in the transaction), multiple destinations and manual fee settings.
  • 2FA support for enhanced security, also available via Telegram.
  • Wrong-Currency detection. The server knows if someone sends BTC to a BCH address and visa versa and automatically creates a new account to be able to recover the funds.
  • A single backup using standard BIP39 mnemonics is valid and enough for an unlimited number of transactions, address and different account types

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours. If you want to support him for his work, please consider donating to him on his bitcoin cash address: bitcoincash:qr5yuq3q40u7mxwqz6xvamkfj8tg45wyus7fhqzug5

Groestlcoin Electrum-GRS 3.2.2 - Ledger & Trezor Edition

What is Electrum-GRS?
Electrum-GRS is a lightweight "thin client" groestlcoin wallet Windows, MacOS and Linux based on a client-server protocol. Its main advantages over the original Groestlcoin client include support for multi-signature wallets and not requiring the download of the entire block chain.

Changes:

  • Qt GUI: seed word auto-complete during restore
  • performance improvements (wallet, and Qt GUI)
  • hardware wallets: show debug message during device scan
  • add regtest support (via --regtest flag)
  • other minor bugfixes and usability improvements
  • If present, libsecp256k1 is used to speed up elliptic curve operations. The library is bundled in the Windows, MacOS, and Android binaries. On Linux, it needs to be installed separately.
  • Transactions that are dropped from the mempool are kept in the wallet as 'local', and can be rebroadcast. Previously these transactions were deleted from the wallet.
  • The scriptSig and witness part of transaction inputs are no longer parsed, unless actually needed. The wallet will no longer display 'from' addresses corresponding to transaction inputs, except for its own inputs.
  • The partial transaction format has been incompatibly changed. This was needed as for partial transactions the scriptSig/witness has to be parsed, but for signed transactions we did not want to do the parsing. Users should make sure that all instances of Electrum-GRS they use to co-sign or offline sign, are updated together.
  • Signing of partial transactions created with online imported addresses wallets now supports significantly more setups. Previously only online p2pkh address + offline WIF was supported. Now the following setups are all supported: > online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline WIF, > online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline seed/xprv, > online {p2sh, p2wsh-p2sh, p2wsh}-multisig address + offline seeds/xprvs > (Potentially distributed among several different machines) Note that for the online address + offline HD secret case, you need the offline wallet to recognize the address (i.e. within gap limit). Having an xpub on the online machine is still the recommended setup, as this allows the online machine to generate new addresses on demand.
  • Segwit multisig for bip39 and hardware wallets is now enabled (both p2wsh-p2sh and native p2wsh).
  • Ledger: offline signing for segwit inputs (#3302) This has already worked for Trezor. Offline segwit signing can be combined with online imported addresses wallets.
  • Added Revealer plugin. ( https://revealer.cc ) Revealer is a seed phrase back-up solution. It allows you to create a cold, analog, multi-factor backup of your wallet seeds, or of any arbitrary secret. The Revealer utilizes a transparent plastic visual one time pad.
  • Fractional fee rates: the Qt GUI now displays fee rates with 0.1 gro/byte precision, and also allows this same resolution in the Send tab.
  • Hardware wallets: a "show address" button is now displayed in the Receive tab of the Qt GUI. (#4316)
  • Trezor One: implemented advanced/matrix recovery (#4329)
  • Windows: use dnspython to resolve dns instead of socket.getaddrinfo (#4422)
  • Importing minikeys: use uncompressed pubkey instead of compressed (#4384)
  • SPV proofs: check inner nodes not to be valid transactions (#4436)
  • Qt GUI: there is now an optional "dark" theme (#4461)
  • Several other minor bugfixes and usability improvements.
  • Fix DNS resolution on Windows
  • Fix websocket bug in daemon

Electrum-GRS Mobile Android

What is Electrum-GRS Mobile?

Electrum-grs is a lightweight "thin client" groestlcoin wallet Android based on a client-server protocol. Its main advantages over the original Groestlcoin client include support for multi-signature wallets and not requiring the download of the entire block chain.

Changes

  • Android: fix some crashes
  • If present, libsecp256k1 is used to speed up elliptic curve operations. The library is bundled in the Windows, MacOS, and Android binaries. On Linux, it needs to be installed separately.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

BE PART OF THE COMMUNITY - You're not a coder but you want to help this great open source project? Here's what you can do

So the crypto space is no longer populated solely by programmers. Many people can't write a line of code but are really excited about the fast-paced developments, especially in an open-source context and want to help in other ways. For those people I've listed some things anyone can do to help the VIA community. This is a work in progress, I'll be happy to add suggestions!
Note that this is not a guide to pumping VIA. This is solely a list of ways to help the community progress and give the project more visibility.
Connect with VIA's social media channels
Since you're reading this, you're probably already subscribed to /viacoin on Reddit. Here are some other channels to like/subscribe/follow/...:
Twitter
Facebook
LinkedIn
Telegram
Slack
But...but... I don't even use TwitteFacebook/... much, why would I join the channel? Social media numbers are important indicators for exchanges, investment groups, etc. When you apply to be listed on an exchange, they ask for the number of subscribers on these platforms. They want to know that there's a solid basic interest in the project.
Plus, higher numbers make people more curious in general. We see many others are interested in a topic, we ourselves start wondering what it's about.
The Telegram is more or less the beating heart of VIA on the marketing and exposure side. Take a look at it once in a while to see if there is currently an exchange polling for new coins, a reddit post that needs some exposure, etc.
Donate to the marketing budget
The VIA marketing team is currently experimenting with ads on social media. These don't cost much, but there is a cost involved. Consider a small donation to the marketing budget:
BTC: 333qb5W7hskvwTmGaWLAvyirgYe4zpFYZR
VIA: VrJ5UDJu72o1y8FFAmiPZeNgCChPytxibM
This way it's not always the same people bearing the costs.
Spread the word about VIA online
Post news and other content about VIA in forums, local websites, crypto groups, etc. Be prepared for scepticism or lack of response. There are many smaller crypto projects out there and people only have so much time. The focus for VIA has been on technical improvement for a long time, only now is marketing and PR catching up. Persistence is key. After letting 10 messages about VIA pass, someone might start wondering what this project is about after message 11.
When myself and some others started posting on this subreddit and in the big crypto related subreddits about VIA, we'd get an average of 2 upvotes, 2 downvotes and 0 comments. Two months later /viacoin has doubled its subscriber count and posts about VIA are starting to get traction: https://www.reddit.com/CryptoCurrency/comments/7abfyh/the_viacoin_team_is_working_on_via_integration/ is an example. There's still a long road ahead, but progress comes with perseverance.
Tell someone about VIA offline
We're not talking about shilling here. With all the news about Bitcoin in mainstream media the subject might pop up at your next family dinner. Tell people about that currently underground cryptocurrency with the 24 second block time, atomic swaps and soon anonymous transactions. It's all about brand awareness here and nothing beats word of mouth in that regard.
You may also think about telling retail store owners about VIA. The local store you visit every day may regret missing the e-commerce boom and want to jump on this train first. Mainstream adoption always creates great exposure for cryptocurrencies.
Don't be annoying online and be a positive member of the community
Go in the VIA telegram chat and tell people about the great idea you have for VIA, instead of asking "When Moon?". Hop on over to the Bitcointalk ANN and let the developers know the hard work is appreciated. Give ViacoinMike a shout out for so enthusiastically working to put VIA in the picture.
When an exchange lists VIA or a big news website dedicates an article to it send them a message saying that you appreciate it. It's a small world, word goes round about communities' ways.
No one in the VIA community is being paid for the efforts they put into this project. It's all passion, a little compliment once in a while encourages people to keep pushing on.
Vote
It closes soon, but there is currently a vote on new coins to be added to the Binance exchange: https://www.binance.com/vote.html
You may look at the current rankings and think there's no way VIA could catch up and reach the number 1 spot. You'd be correct. But it's still important to show exchanges that, while VIA doesn't yet have the numbers of the big hype coins, there is a solid community that makes it worth listing at some point in time.
Get creative
Become Viacoin Jesus.
Make a Viacoin puzzle
Draw Viachan
Put some sneaky viral marketing on your band's instagram (disclaimer: mine)
...
To conclude: it doesn't take much to help an open-source project like VIA. But when you start noticing the positive impact of your small contributions, it's very rewarding. Be part of something big.

[uncensored-r/CryptoCurrency] COSS Exchange and COSS Token - A Full Summary

The following post by ychok is being replicated because some comments within the post(but not the post itself) have been openly removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ CryptoCurrency/comments/74rjfo
The original post's content was as follows:
Let me get started by stating I am no way involved with the COSS team. I simply am a COSS holder who wants to share this coin with others. Please note, I am writing this without an opinion and just stating facts (I will include a portion below with my opinions and an explanation of my thought process). Everything I say can be double checked with some DD and if I have time, I will come back and link said facts!
What is COSS?
  • coss.io stands for Crypto One Stop Solution. Essentially, COSS is doing a lot. From their own exchange, to their own markets, a payment gateway for businesses to accept crypto as payments, and even more planned on their roadmap, COSS has a lot on their plate. The ICO ended a few days ago at a rate of 1 ETH for 6000 COSS making the price about 5 cents a COSS.
What does COSS do?
  • Well as an exchange (no its not decentralized), COSS charges fees for trading. COSS also charges fees for their marketplace or using their payment gateway plug-ins. 50% of the total revenue they obtain is distributed to the COSS tokens weekly. The way it works is that the crypto that was received in revenue as a fee is what is distributed. Example: If the total trading volume on the exchange is 100,000,000 for the week and Ether was 20% of that volume and BitCoin was the other 80%, the payout will be 80% in bitcoin and 20% in ether.
What is the payout formula?
  • [(Daily Trading Volume) x 7 x 0.002 x 0.5]/93 mil = payout per coin. Multiply this by how many COSS you hold for the value of your payout, but remember the payout will be in a plethora of coins that are traded on COSS!
When are payouts?
  • Payouts occur EVERY Sunday (weekly), with the first payout to be this Sunday (October 8th). I am not sure what time of day this will occur.
How do you receive payouts?
  • The simplest way to receive payouts is by holding COSS tokens in your COSS wallet on coss.io
  • You can receive the payout if you hold COSS on MEW, but it requires additional steps in order to have those coins be a part of the payout. If you use MEW you need to do a bit of configuration. Use this tutorial: https://coss.io/coss-token-revenue-share-tutorial
What is the total supply?
  • Currently, the circulating supply is 93 million. 80 million of this 93 million are token holders, 10 million is set aside such that the revenue generated by these 10 million tokens goes to charity, and the last 3 million are used by the team to payout bounties and such. (Coinmarketcap has yet to be updated, request has already been sent in)
What is the current marketcap?
  • At a rough price of 15 cents per coin, the marketcap for COSS is around 14 million
Where can I buy COSS?
  • At the moment, COSS is being traded on coss.io, etherdelta, and HitBTC
My opinions:
1) COSS, based on numbers, is simply undervalued. For a token that already has an existing functional product, its marketcap is well below what it should be. Trading volume has also increased significantly in the past few days! Imagine receiving profits from an exchange like Bittrex or Binance I urge you to browse their website and look at everything for yourself to make your own judgement!
2) There is a lot of work to be done on the exchange, but it is just getting started and is still in Beta. Good things take time. I remember when Binance first began and the struggles it went through, and look at it now. I have faith COSS can do that same. Currently, the things I believe that need to be fixed are exchange UI upgrades to make them more appealing to the eye and deposit/withdrawal times.
3) There is a lot of concern about COSS being a scam due to the team's association with VRS. I definitely had to look into this and found that Rune, on of the founders, addressed this concern. For me it was a satifactory explantion stating that VRS was not a scam, but a failed project. Please read bullet 4 to get the link to the full statement and other FAQ's
4) There are tons of FAQ's and known issues that are being asked about COSS. These two links pretty much cover them all at the moment. Each link has some different information, so please read both!
FAQ - 1 https://www.reddit.com/COSS/comments/74pw7h/all_info_to_clear_up_confusion/?st=j8gjl9jz&sh=b777583e
FAQ - 2 https://www.reddit.com/COSS/comments/7471mv/fqa_for_coss/?st=j8gawdbq&sh=d4cf9518
