- add 'attester.grace' grace period to attester service
- enable 'latest' beacon block root strategy
- add combined attestation pool strategy
- use strategy fetchers for data where appropriate
Plus the usual round of performance, stability and security updates. The full list of changes can be found in CHANGELOG.md.
Notes for multi instance
Multi instance gives the option of running a secondary instance of Vouch with a static-delay. The secondary instance will attempt to perform validator duties if it does not detect another instance performing them. Key considerations:
- You should only attempt to use multi instance if you have slashing protection external to Vouch (e.g. Dirk). A multi instance setup without slashing protection will likely lead to your validators getting slashed.
- You should test your setup thoroughly on testnets before moving to mainnet.
- The
static-delayparameters you need to set will be relative to your infrastructure. As a general guide - shorter delays will lead to more duplicate signing attempts; the longer the delay the less likely the secondary will perform duties within the necessary window.
