As I perceive the SVP protocol, a shopper might 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 high of that block.
How a lot complete information would that be, roughly? I suppose for those who have been starting with 0 data, you would want all the block headers, starting from the genesis block? However as soon as you’re satisfied you’re looking on the head of the precise chain, you would discard all the historic block headers, and simply save a latest one as a trusted place to begin to judge subsequent transactions?
I suppose the premise of my query is defective, as a faux transaction might at all times be embedded in a faux chain, if sufficient computing assets have been obtainable. So, there is no such thing as a quantity of knowledge 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 can be how a lot would the electrical energy value to create one faux block header at at the moment’s problem stage? 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.
