As I perceive the SVP protocol, a shopper may be moderately sure {that a} transaction has been accepted on the blockchain in the event that they know it’s a member of a sure block, by way of the Merkle path, and an affordable variety of blocks have been mined on high of that block.
How a lot complete knowledge would that be, roughly? I suppose in the event you have been starting with 0 information, you would want the entire block headers, starting from the genesis block? However as soon as you’re satisfied you’re looking on the head of the suitable chain, you can discard the entire historic block headers, and simply save a current one as a trusted place to begin to guage subsequent transactions?
I suppose the premise of my query is defective, as a pretend transaction may all the time be embedded in a pretend chain, if sufficient computing assets have been accessible. So, there is no such thing as a quantity of information that insures a transaction is legitimate, with out entry to different data, e.g., what’s the longest chain presently in existence.
A greater query for my functions could be how a lot would the electrical energy value to create one pretend block header at right now’s issue degree? Figuring that blockchain presently pays round $60K to mine one block, I might guess it have to be in that order of magnitude, although smaller since we’re eradicating the race situation.
