- bmh_ca 9y agoIsn't a double (n+1) ledger the definition of the inability to double spend (presuming Atomicity or reconcilability)? That's a genuine question.
- bhaak 9y agoIt's distributed. You can't presume atomicity. The consensus rules ensures that everybody (eventually) stays on the same chain and the PoW mechanism ensures that (after a few confirmations) it would be too costly to change the blockchain for a double spend.
