Events By Dec 07, 2023 No Comments
TL;DR: Zac from Edge & Node shared more information on Horizon, a new design for The Graph protocol that promises improved trust, efficiency, direct indexing fees, a larger addressable market, and greater simplicity. The article also covers updates on various protocols and repositories.

Welcome to another edition of Indexer Office Hours!

Today is December 5, and this is Indexer Office Hours 136.

Opening remarks

Welcome, and introduction shout out to indexer, Stake Machine, for being interviewed on the GRTiQ podcast. Congratulations!

The latest updates to important repositories

Execution Layer Clients

  • Erigon v2.0 New release v2.55.0 :
    • Fix outstanding know header==nil errors + reduce bor heimdall logging.
    • Flags: bump default value of db.size.limit to 12TB.
    • Existing nodes whose MDBX page size equals 4kb must add –db.size.limit=8TB flag. Otherwise, you will get MDBX_TOO_LARGE error. To check the current page size, you can use make db-tools && ./build/bin/mdbx_stat datadir/chaindata.
  • Nethermind: New release v1.23.0 :
    • Nethermind can now be an execution client for OP Stack chains, including Optimism and Base mainnets.
    • The OP Stack network has EL and CL concepts similar to Ethereum’s. Nethermind works as an EL client; refer to optimism docs for how to run op-node as your CL client.
    • Reduced memory usage spikes when a node is overloaded with CL requests.
    • There is now support for initializing the Nethermind database from a .zip snapshot file.
  • Avalanche: New release v1.10.17 :
    • Added avalanche_{chainID}_blks_build_accept_latency metric

      • pull_gossip
      • push_gossip
      • put_gossip which is deprecated
      • built
      • unknown
    • Added avalanche_{chainID}_issuer_stake_sum metric

        • Updated the default value to 1 to align with the change in default gossip frequency
      • -consensus-on-accept-gossip-validator-size
      • -consensus-on-accept-gossip-non-validator-size
      • -consensus-on-accept-gossip-peer-size
