Satoshi’s Shield

The wall.

Every output the shield is made of, oldest block first. One cell is one coinbase transaction, fifty bitcoin each, mined between January 2009 and April 2010.

Loading the wall.

The block list comes from the Patoshi pattern found by Sergio Demian Lerner and curated by Jameson Lopp. Every height was re-checked against the coinbase script the chain serves today, and anything that did not match is in the rejected list, not in the shield.

The output

Press a cell in the wall, or type a block height above.

How the set was built

One. The published Patoshi block list is read as a claim: a block height and the public key that block paid.

Two. For every one of those heights the chain is asked for the first transaction of that block and its raw bytes, and the output script is parsed from them.

Three. The public key in that script has to match the claim. Anything that does not match is reported and kept out of the shield.

Four. The script’s hash is asked for its unspent outputs. If the coinbase output is still there, the cell is asleep. If it is gone, the cell is marked moved and the transaction that took it is recorded.
