As I perceive the SVP protocol, a consumer 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, through the Merkle path, and an affordable variety of blocks have been mined on prime of that block.
How a lot whole information would that be, roughly? I suppose in the event you had been starting with 0 information, you would want the entire block headers, starting from the genesis block? However as soon as you might be satisfied you’re looking on the head of the proper chain, you can discard the entire historical block headers, and simply save a latest one as a trusted start line to judge subsequent transactions?
I suppose the premise of my query is defective, as a pretend transaction may at all times be embedded in a pretend chain, if sufficient computing sources had been out there. So, there isn’t a quantity of information that insures a transaction is legitimate, with out entry to different info, e.g., what’s the longest chain at present 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 at this time’s problem degree? Figuring that blockchain at present pays round $60K to mine one block, I’d guess it should be in that order of magnitude, although smaller since we’re eradicating the race situation.
