One reason Nockchain is so scalable is that it doesn't require multiple executions across nodes. This is a key ingredient in our "secret sauce," so it's worth understanding it. Bitcoin nodes, for instance, must verify blocks by re-executing signatures and scripts for the transactions within them, while the "work" is the separate task of SHA-256 hashing. In Nockchain, the "work" is the act of proving itself. Nodes on the Nockchain network do not replay transaction history; instead, they just verify a single, succinct proof included in the block. This proof confirms that any offchain computations and the batch of transactions are consistent with the prior state. Forcing everyone to re-run the same execution is a huge bottleneck, so it should be easy to intuit why this is a game-changer!
