Gas (Transaction Fee)
Definition
Gas is the unit measuring computational effort for blockchain operations, determining transaction fees. Users pay gas to incentivize validators and prevent spam. Post-quantum transactions may require different gas calculations due to larger signature verification costs.
Technical Explanation
Gas components: base fee (protocol-determined minimum), priority fee (tip to validators), and gas limit (maximum units for transaction). Total fee = gas used × gas price. Complex operations (smart contracts) consume more gas than simple transfers.
Post-quantum impact: larger signatures mean more data (storage cost) and verification computation. Gas models may weight signature verification differently. Optimized implementations minimize the post-quantum overhead.
SynX Relevance
SynX transaction fees account for SPHINCS+ signature verification costs. The fee model balances quantum resistance overhead with practical transaction costs. Optimized verification keeps fees reasonable despite larger signatures.
Frequently Asked Questions
- Are post-quantum transactions more expensive?
- Slightly—larger signatures mean more data. Optimizations minimize the difference versus classical transactions.
- How do I estimate transaction fees?
- Wallets estimate automatically. Simple transfers have predictable costs; complex operations vary.
- What if I set gas too low?
- Transaction may fail or wait indefinitely. Use recommended settings from your wallet.
