What Are Gas Units in the Chronicle Protocol?

Gas Units Explained

• Every blockchain operation consumes a certain number of gas units. For example, a simple ETH transfer on Ethereum requires 21,000 gas units, while more complex operations (like ERC-20 transfers or DEX swaps) can use between 45,000–500,000 gas units1.
• In Chronicle, gas units represent how much computational work is needed to submit and process oracle updates.
• The cost an entity pays is determined by gas units × gas price (in gwei); more units or a higher price means greater cost.

Gas Units in Chronicle's Oracles

• Chronicle Labs uses Scribe, a gas-efficient oracle design leveraging Schnorr signature aggregation, which drastically reduces the number of gas units needed for updates23.
• According to recent data:
  • In Q2 2024, Chronicle updates on Ethereum required 53,000–76,000 gas units1.
  • In Q3 2024, the average was about 85,000 gas units on Ethereum, but improved to 64,100 by Q4 2024 after further optimizations231.
  • On Layer-2s, gas units per update averaged 130,800 in Q4 20243.
• These figures show that Chronicle’s oracles are among the most gas-efficient in the market, often rivaling simple ERC-20 transfers.

Why Gas Efficiency Matters

• The fewer gas units required, the cheaper and faster updates are for users and protocols.
• Chronicle’s optimizations enable significant cost savings compared to competitors (e.g., Chainlink), making oracles more accessible and scalable for DeFi projects31.

Additional Context

• Gas units themselves don’t have a direct USD value—they measure computation. The final transaction fee in USD depends on current ETH prices and network congestion1.
• Chronicle can’t control the gas price set by the network but focuses on minimizing the gas units needed for each update.
