Hello, I've written this proposal. C&P of the overview:
Satoshi's original paper describes a way of prunning spent transactions in the blockchain to save storage space while it remains consistent and verifiable, but it's useless for partial blockchain downloads: while you can know if a given transaction is in the blockchain, you can't know if it has been spent in a subsequent transaction. This proposal describes how to add a hash-tree based check in the blockchain that allows to verify if a transaction is unspent without downloading and checking all the blockchain. The idea is not new, but at the time of this writing there isn't any technical description of how this should be done. Aditionally, this solution is rather simple. https://en.bitcoin.it/wiki/User:DiThi/MTUT Cheers -- Alberto Torres Ruiz (a.k.a.
