Tokens

Instead of free text, a block can hold transactions. Change an amount and every block from there on is no longer valid.

Try this
  1. Change an amount in block 3 of Peer A. Which blocks turn red?
  2. Change the From or To name instead. Any change at all, however small, breaks the block.
  3. Compare the three peers. If they disagree, who is telling the truth?
Puts everything back as it was.
