ABCC Digital Asset Exchange will issue ABCC Token (AT) on July 9th 2018 (UTC+8) as part of our User Incentive Plan. 1. What is ABCC Token?

Participating in various activities such as community building, interaction between members and ABCC, proposing suggestions to ABCC and others. 3. Initial Allocation Below is a breakdown of the initial allocation of AT. 4. Issuance We will adopt a mechanism called “Trade Contribution + Simultaneous Release” to issue AT. 4.1 Trade Contribution In order to encourage our users to trade on ABCC, we have decided to reward our members with 50% of the total supply of AT. Of the 50% rewarded to users, 4/5 (i.e. 40% of the total supply) will be used to reward members who trade on our exchange platform via the “Trade-to-Mine” (ToM) mechanism. The other 1/5 (i.e. 10% of the total supply) will be granted to users who traded prior to the issuance of AT. 4.1.1 Trade-to-Mine (ToM) 40% of the total supply of AT will be used to reward members who trade on our exchange platform via the “Trade-to-Mine” (ToM) mechanism. Drawing inspirations from the Bitcoin mining model, we have adopted a similar inflation model for AT. In particular, the ToM mechanism includes two steps, i.e., “release” and “distribution”. Release The release of AT follows a half-life decay pattern. There are 6 half-life periods in total with each period being 120 days (roughly 4 months). We will release half of the total supply of AT in the first 120 days. The number of AT to be released in the following half-life period will be halved, and so on. Please see details of AT release schedule below. Within each half-life period, one “block” will be generated every 6 hours. The same number of AT will be released for every block inside the same half-life period. For example, the number of AT to be released for one block in the 1st half-life period is calculated as follows. The total number of AT in the 1st half-life period: 42,000,000; The number of days in the 1st half-life period: 120 days; One block will be generated every 6 hours; The number of blocks to be generated every day: 24 hours / 6 hours = 4; Therefore, the number of AT to be released for one block in the 1st half-life period: 42,000,000/120 / (24 hours / 6 hours) = 87,500. Distribution We will distribute AT released in a block to members per the percentage of their trading fees within that block. If it so happens that there are no members eligible for the rewards in a certain block, the released AT assigned to this block will be distributed in the next block. 4.1.2 Reward for Historical Trades 10% of the total supply of AT will be used to reward eligible existing users. We will distribute the rewards to the eligible users based on their cumulative trade volume contribution ending 24:00 June 27th, 2018 (UTC+8). The rewards will be frozen for 180 days after the launch of AT. 4.2 Simultaneous Release AT will be released to the platform, team and investors in proportion to the number of AT released and distributed to members via Trade-to-Mine (ToM). The number of AT released via Simultaneous Release = the number of AT released and distributed via ToM * (50% / 40%).
Grin coin is a private & lightweight open source project based on the mimblewimble blockchain implementation. MimbleWimble is a lightweight blockchain protocol proposed by anonymous author that goes by the name Tom Elvis Jedusor (inspired by Harry Potter) in July 2016. Since then, the proposal has gained a huge following among Bitcoin and privacy advocates. Unlike bitcoin or ethereum, there are no addresses in Grin. In order to transact using Grin, both wallets must communicate with each other online with the results broadcasted to the network. Another key different is that transaction history (sender, receiver, amount) will not be recorded on the blockchain. Due to the removal of these information from the transaction, the data size remains small and that keeps the blockchain lightweight. New nodes can easily join the network without having to download a large blockchain. Grin coin was launched without an ICO, fundraising, or pre-mine. Developers around the world contribute openly with the goal to ensure the coin distribution remains as fair as possible. There are 2 popular wallets widely available to interact with the Grin network.

There are 2 hashing algorithms involved with Grin. Cuckoo-29 is meant for GPU mining while Cuckoo-31 is meant fo ASIC mining. This is a deliberate design to encourage miners to eventually move into ASIC mining for efficiency while keeping it fair at the beginning of the launch. Grin coin has launched its mainnet on 15th January 2019 and is now available for mining and trading.
