Computers Quote by Vitalik Buterin
“I think people don't realise that running a piece of code that verifies some conditions for a financial transaction, that by itself is a lot less work than verifying a cryptographic signature, and so even if the virtual machine is inefficient, the cryptographic signature is still going to dominate.”
About This Quote
Source Talk: Ethereum Scaling Discussion, 2021
Verifying a cryptographic signature is computationally heavier than checking transaction conditions, so signature verification dominates performance costs.
In simple terms: Signature checks cost more than logic checks.
Key Takeaway
Optimize signature verification for efficiency.
