UTXO Change Digest #59

Open zack-w opened 6 years ago

zack-w commented 6 years ago

Problem: There is no easy way to communicate main chain UTXO changes between trusted parties. Currently, any parties wishing to update a UTXO ledger must process a block which contains complex logic.

Solution: When one party has processed a main blockchain block, the party can generate a UTXO Change Digest [BN -> BN+1] which is in the following format:

{
   block: N+1,
   balances: {
       addr1: balance,
       addr2: balance,
       ...
   }
}

A UTXO Change Digest can easily be used to update Main Blockchain Ledger LN -> LN+1
