Scratch

1. Create a user account list to which stores user balances

2. Implement the user account as wallets

3. A feature to create and save the current state of chain

4. A feature to load a saved state of chain

5. Create multiple nodes to mine the blocks

6. Create a feature to send coins to other users

7. [API] Create a feature to view the balance of a user

8. Create a feature to view the transactions of a user

9. Create a feature to view the blocks

10. Create a block explorer

11. Create a database to store all the accounts for reference which has balance>1 (to be used in the block explorer). It will also act as a node.

Ideas

1. Use the NATS server to create a pub/sub system to push updates and syncronize the chain across all the nodes.
2. Create a central publisher for transactions to push them to mempool and again get status and push the transaction status to user, create a sql db to keep track of this transaction per user.

Notes

• Pos concept: How do we assign proper weights to them based on the number of tokens they staked? We fill our lotteryPool with copies of the validator’s address. They get a copy for each token they’ve staked. So a validator who put in 100 tokens will get 100 entries in the lotteryPool. A validator who only put in 1 token will only get 1 entry. We randomly pick the winner from our lotteryPool and assign their address to lotteryWinner.
