[Bitcoin-ml] [Research] Masterblocks: Scaling Blockchain by summarizing balances

[Alexey Eromenko]

If you don't download all blocks (which includes all UTXO), how do you
know balances? You can't !
My idea allows to download only a subset of blocks (all blocks since
Masterblock) for a new node setup.
