Raicoin(RAI): A Revolutionary Coin for Real Life & Daily Use

================================================================================================

Raicoin is designed for real life & daily use, it's a crypto system with: high performance, low latency, well decentralized, easily extendable. We introduce many novel designs to achieve these goals.

1.Block-lattice with Reward

All nodes with election weight can earn reward.
The block-lattice idea is first introduced by NANO, by the amazing technique, transaction latency is reduced to less than 1 second. But NANO and those similar coins do not have reward for nodes, most of coin holders have no incentive to run their own nodes, they just put coins in exchanges or set official nodes as their representatives. We can see only Binance Exchange itself controls more than 20% NANO total supply (https://nanocean.org/top/ @2020/08/24). It is basically impossible to achieve well decentralization without node incentive.
Another reason Raicoin introduces reward is we need it to motivate third parties to develop various extensions.

2.Credit Secure Mechanism

Accounts destroy little amount coin to get credits from the network, than allowed to do (20 x credits) transactions every day(In a word, buy once for life).
Any account must have at least 1 credit when it is created.
The cost of credit will gradually decrease.
Transactions from accounts with high remaining percentage of allowed transactions will be processed first when the network is busy.

3.Achievable and Sustainable high performance

Two types of nodes are designed: light node and full node. light nodes can not only do pruning but also unpruning when needed.
light nodes are designed to run on ramdisk/NVMe/SSD as election nodes, and full nodes run on HDD as backup nodes.
Rough performance on different device: 10k+ txs/s (ramdisk), 2k+ txs/s (NVMe), 1k txs/s(SSD), hundreds txs/s(HDD).

4.Fullmesh Network & Bandwidth Saving

We design a fullmesh network layer to optimize election algorithm, it will save up to 90% bandwidth cost.
The fullmesh network is also used for fair proven airdrop.

5.Programmable
More than 50% of the block content can be programed by the upper layer services and third party apps. By this feature, we can easily add new features for the project. The system is also suitable for running various third-party apps.

6.Privacy
Coin mixer can be developed based on the Programmable feature. Third party may be happy to develop and run a mixer to get users and node reward. An official implementation may also be developed if necessary.

7.Account Types

There are three kinds of accounts: Transaction, Airdrop, Representative.
Transaction accounts are generated in wallet for normal use, these accounts are allowed to Send, Receive, Change Representative, Increase Credit.
Airdrop accounts are used to fulfill airdrop, these accounts are allowed to Receive, Change Representative, Destroy Self, the coins in airdrop accounts can't be spent.
Representative accounts are running on nodes, equivalent to node accounts.

8.Distribution

All coins except those in airdrop accounts are generated by node reward.
How node reward works:
The reward is transaction driven, that is any new block created by Airdrop accounts or Transaction accounts will allow their Representative node account to create a reward block with average 24 hours delay.
New generated coins of each year:
   1st year: 40M,
   2nd year: 30M,
   3rd year: 20M,
   4th year: 10M, from 5th year: about 5% coins.

9.Airdrop

There are 10000 Airdrop accounts as genesis accounts, each of them have 1000 RAI coins that can't be spent. These accounts are running on rai_airdrop app automatically.
These airdrop accounts change their representatives every 24 hour. The choice is randomly and based on the cumulative online time of the qualified nodes, that is, the higher online time, the higher probability to be chosen.
Because the Raicoin network is a full mesh network, every node connects with each other, so all participants can count and get same result of the whole network's online statistics, then check it with the actual airdrops to verify fairness.
Airdrop will last 4 years, the approximate amounts by time:
1st quarter of 1st year: 7M,
2nd quarter of 1st year: 4M,
3rd quarter of 1st year: 3M,
4th quarter of 1st year: 2M,
2nd year: 5M,
3rd year: 2M,
4th year: 1M.
To anti sybil attack, in the first 2 quarters, only invited nodes can get airdrop. And after then all nodes can get airdrop.
