Summary
The team successfully Ragnarok’ed the existing network which was useful in identifying some issues that had to be fixed. The testnet will be re-deployed with these fixes to the public shortly. An additional testnet will also be deployed soon for potential THORNode validators to practice joining and leaving.
Dynamic Network Fees
A feature that was added was “Dynamic Network Fees”. This monitors all reported gas fees on incoming transactions (both fee-amount and fee-rate) and saves to the chain. Transactions are charged an amount 3 times the trailing average for the gas for each chain, and the actual gas used by the nodes is 1.5 times the incoming. This means outbound transactions are always prioritised *more* than incoming, and the gas used is always subsidised. An example is:
- The average of incoming Bitcoin fees is 10 sats/byte, with average amount 4000 sats used. ( feeAmount = 4000, feeRate = 10, feeCoin = BTC.BTC ). (Incoming Bitcoin transactions will likely be of type 2-in-3-out so around 400 bytes).
- The user who is swapping to Bitcoin is charged 3 * 4000 BTC.BTC = 12000 BTC.BTC . This is taken from them as RUNE valueInRune(12000, BTC.BTC) (since all transactions go via RUNE at some point) and paid into the TotalReserve.
- Nodes then use a rate of 15 sats/byte to pay the outbound transaction. Most likely the outbound transaction is a 2-in-2-out so around 300 bytes, so the total amount is 4500 BTC.BTC which is taken from the Bitcoin vault balance.
- This transaction is then observed and reported back into THORChain and the Bitcoin pool is paid an amount equal to twice the fee (9000 BTC.BTC ) but in RUNE. This cause arbitrage and the Bitcoin pool is topped up by the market at an amount at least equal to 4500 BTC.BTC .
While appearing complex, this mechanism has the following simple characteristics:
- Fee rates are responsive to short-term fluctuations and should be high enough to always be processed in their respective mempools.
- The fee mechanisms is standard across all chains, no matter the fee-type.
- Liquidity stakers are providing the capital for gas, but should always be reimbursed.
- The network makes a small margin on every swap.
