WebJan 28, 2024 · The key to “Smart Contracts” on Blockstack is making sure both parties digitally signed the same hash (as depicted above). The digital signature is unique to you and nobody can forge it. Websmart contract (based on the transaction steps to be performed), the more gas that must be paid to execute the smart contract. Thus, gas currently acts as an impor-tant gate to prevent overly complex or numerous smart contracts from overwhelming the EVM.2 Smart contracts are presently best suited to execute cspf engineering limited
