In a year filled with plague and disruption, 2020 was one that resulted in transition and positive momentum for Coin. We transitioned to a sole focus on decentralized finance (DeFI) and $COIN from a security to a utility token. Additionally, reshifted focus on the following three priorities:

  1. Community
  2. Token utility and value
  3. Engineering

These priorities will continue to ensure that Coin is in complete alignment with our token holders. This has included the Coin network’s revenue model which guarantees that the team will only be rewarded as the network grows and value is created for $COIN. …

Happy holidays to you and all of your loved ones around the world! We wanted to provide an update regarding to token events:

  • $COIN airdrop for previous security token holders
  • $COIN token burn

For all previous holders of $COIN, we completed an airdrop of 2% of the total token supply. More specifically, we used 2% (2,142,857) of the total token supply of 107,142,857 and distributed that amongst the old token holders to demonstrate our appreciation for your continued support through the years. The distribution was in accordance with current balance and did not include any corporate addresses. This resulted in a ~17% token bonus. …

So let’s first talk history. We started our journey in 2017 and began using the ticker symbol/mark $COIN as our token ticker symbol for the following reasons:

  • Alignment with the company name
  • No record of trademark and use in commerce by any other company
  • Alignment with our mission of simplicity (which we believe the name embodies)

As with other IP, we found value in this asset and wanted to protect the symbol for the best interests of our business and our token holders (which is not an uncommon practice). This process included months of time and resources working alongside the USPTO office for approval. …

We are excited to reveal details of our staking rewards program. This is a program that gives stakers the opportunity to earn rewards as a direct result of revenue from the Coin Exchange platform. As a staker, you earn more $COIN as the Coin ecosystem grows!

By staking your $COIN and participating in the Coin staking program, you accrue rewards immediately. Each month Coin’s staking rewards will be calculated at 7% of the current $COIN in the staking reserve (21,785,714 $COIN). The first month’s rewards are 7%, approximately 1,525,000 $COIN, that will be distributed across all stakers. Each month thereafter, the smart contract will take 7% of the new staking reserve balance for distribution again. The staking reserve will continuously be refilled from $COIN buybacks from revenue on a weekly basis. In short, this means the more the Coin platform is used, the more you benefit. With that said, even with low initial volumes, rewards are high because of the initial balance in the Coin staking reserves. Your reward percentage will be calculated based on your contribution to the total staked $COIN on the network. …

Hello Coinvestors;

Let us begin by saying that today is a milestone day in many aspects. It marks the culmination of months of work and planning. We were very excited about this release of our DEX to MainNet and all the activities planned around this.

We have always endeavored to be completely transparent with our Coin family and that continues with this update. Our plan has been to execute the following activities today on Monday, December 21st:

  • Last Tranche of Token Distribution for the TrustSwap Liquidity Offering
  • Coin Exchange MainNet launch
  • Coin Exchange Browser Extension and AI Launch
  • $COIN Utility Token upgrade for existing token…

Today, the traditional financial system operates on a centralized model. With forms of money that always require third party custody and arbitration, we miss out on the benefits of programmability and automation, not to mention the lack of real ownership and risks of censorship.

This changes with the advent of Bitcoin and blockchain technologies, which enable people to both own and program money. The result is the rapid advances in peer-to-peer (P2P) finance, transactions that do away with centralized intermediaries. One key innovation which enables this is Hash Time Locked Contracts (HTLCs).

Simply put, HTLCs are time-bound conditional payments through programmable escrows which enable conditional P2P value transfer to minimize counterparty risks. …

On October 16 this year, OKEx, one of the largest crypto exchanges in the world, suspended all cryptocurrency withdrawals after one of its keyholders Star Xu was being investigated by the public security bureau in China. It exposes one of the key weaknesses of centralized exchanges — that users are not in control of their private keys and cryptocurrency holdings.

It is an irony for the crypto industry, which prides itself on its decentralization ethos, to be dominated by centralized exchanges. The custodian of funds and processing of transactions on behalf of users has led to many problems, including costly fees, delays, security, and regulatory risks. …

In the last article, we explored the primary risk that users face while using a centralized exchange, namely the relinquishing of control of cryptocurrencies’ private keys and personal information to the exchange. As security and privacy are increasingly valued by users, more and more centralized exchanges are implementing decentralized technologies.

The most popular format for a decentralized exchange is a decentralized gateway. This can be thought of as a network of gateway keepers that hold digital assets sent to them by users who are then issued IOUs for trading.

Here is the key improvement over centralized exchanges: the IOUs issued are not stored in a centralized database. Rather, the user retains control over the private keys to their IOUs, which are managed through a blockchain. Furthermore, the actual assets that the gateway hold is controlled by several people or parties via a multi-signature address. This provides an improved measure of security and decentralization. …

Today there are thousands of cryptocurrencies out there. Technically, each cryptocurrency is tied to its native blockchain which records the transaction history. While it is easy and secure to transact cryptocurrencies within the same blockchain, it is more complicated and less secure to do so across different blockchains due to the lack of an inter-chain trading mechanism.

Thus was born centralized crypto exchanges. In essence, a user who deposits digital assets into a centralized exchange gets back an “I Owe You” (IOU) from the exchange acknowledging that it owes the user the actual assets represented by the IOUs.

IOUs are an efficient and effective tool for trading cryptocurrencies, compared with transacting across two distinct blockchains. Within a single environment controlled by the exchange owner, the IOU exchange process is fast, simple, and user friendly. As the exchange aggregates a large group of users, liquidity and trading pairs gradually ramp up. As the exchange achieves scale and automation, it allows for sizable profits through the levy of trading fees. This in turn funds better user interface and business development to attract even more users and trading volumes, turning this into a virtuous cycle. …

Uniswap is a decentralized exchange protocol that allows users to swap ERC20 tokens, peer-to-peer. These are tokens built on top of the Ethereum blockchain. In this article, we will explain how Uniswap and its liquidity pool work.

As a decentralized exchange protocol, Uniswap does not rely on the traditional order book model which is adopted by centralized exchanges. Instead, Uniswap uses exchange contracts that hold a pool of specific ERC20 tokens and ETH that users can swap with each other.

Anyone can initiate an exchange contract to register a new token for trading. To trade ETH for a token, a user first sends ETH to the contract’s pool, the location of which is specified by the exchange contract address. …
