Lakichain is a proof-of-work blockchain which contains blocks of transactions consisting of the currency Lakicoin
- There is a finite number of transactions per block
MAX_TRANSACTIONS_PER_BLOCK
The "mining" of a block basically works by brute forcing a value called nonce so that the hash of the block including this nonce contains
a specified amount of 0's (MINING_DIFFICULTY) at the start. The hash is base16 so the amount of 0's in binary would be 4-times as much
The transactions are based on public/private key cryptography. They get signed and verified with the ed25519 algorithm using the ring crate
After a transaction has been created and signed with the private key that belongs to the public key of the sender of the transaction, it can
be added to the list of current_transactions of a Lakichain object. It is not immediately validated (has the address enough balance? etc.),
it instead is only validated when the mining of a new block is requested, which looks trough all pending transactions, orders them
by the highest fee first and also removes transactions from current_transactions that are already in the blockchain.
You can see if a transaction is pending or valid by using the supplied functions.
A miner can request a block from the chain, mine it and send the nonce he calculated back to the chain. The block he receives also includes
the miner reward transaction where he receives all fees of the transactions included and also a MINING_REWARD.
The blocks the miner request get added to a pending_blocks list, which makes sure the nonce sent back from the miner belongs to
the block he originally requested. If someone else mined the block with the same index first, all other miners that mine this block get a invalid response after
sending back their nonce
The the current amount of Lakicoin someone owns depends completely on the transactions that are in the blockchain
