Title: Incremental chain download using SPV proofs? Post by: grau on November 02, 2013, 05:21:48 PM What do you think of a protocol extension for SPV style chain download of the subset relevant for one's wallet?
A node would query SPV style proofs for transaction inputs relevant to it until proofs reach coin bases or verified by previous proofs. Title: Re: Incremental chain download using SPV proofs? Post by: Mike Hearn on November 02, 2013, 05:25:32 PM Wallets don't need to know the dependencies of their own transactions, so I don't see why this would be useful.

Post by: Peter Todd on November 02, 2013, 10:07:25 PM Applications that care about origin, colored coins in particular, are already very SPV compatible; you're just looking at it from the wrong direction. What they could do is start with the genesis transactions and scan the chain forwards, rather than starting with a alleged colored coin and scanning backwards.
