2.60.8

Highlights

This release schedules the Ahmedabad hardfork for the Polygon mainnet and the Gandhinagar hardfork for Amoy. Thus it's mandatory for all Polygon users.

This release also fixes Issue #11936 debug trace RPC error in Polygon Amoy.

2.60.7

Breaking change:

Release process:

Starting this release we're introducing some changes to our release process:

• release version without prefix “v” in a docker tags, released artifacts, git tag, etc.;
• released archives now includes 10 binaries: erigon, downloader, devnet, evm, caplin, diag, integration, rpcdaemon, sentry, txpool;
• released docker image now includes 7 binaries: erigon, integration, diag, sentry, txpool, downloader, rpcdaemon (same binaries as built for released archives just baked to the docker image);
• docker images will be released on Dockerhub repository “erigontech/erigon”. Previous images, released in repository “thorax/erigon” will remain as is. We are not planning to copy old images to the new dockerhub repository.
• multi-platform docker image available for linux/amd64/v2 and linux/arm64 platforms and based on alpine:3.20.2; No need to pull another docker image for another different platform.
• docker images now contains label “org.opencontainers.image.revision” which refer to commit id from the erigon project, used to build artifacts.
• all build flags now passed to the release workflow — so, user can see previously missed build info in our released binaries (as well as in docker images) and also better build optimization expected;
• We are not publishing Windows binaries as it requires some work. We will publish it again once it will work as expected. Meanwhile Windows users can build erigon binaries locally on Windows machines.

Description of the change

Require resync

Yes

Improvements:

• Sync now including .idx files (indices). Erigon downloding them instead of re-generating
• Starup time fixed
• Too high read-IO fixed
• latest state (domain folder) size reduced by 30% (~200gb on bor-mainnet)
• 2x reduced chaindata: 12Gb on eth-mainnet, 32Gb on bor-mainnet
• 2x less RAM: 25Gb on eth-mainnet, 40Gb on bor-mainnet. We will reduce it in future
• mining suppport
• prune doesn't impact chain-tip performance
• new CI for binary artifacts release. and docker.

Known problems

• trace_callMany multiple txs support: #11798

v2.60.6

Improvements:

• compatibility with geth - of stateDiff encoding by @AskAlexSharov in #11362
• callTracer: don't capture logs txs failed with error by @AskAlexSharov in #11375
• diagnostics: export system info by @dvovk in #11567

Bugfixes:

• fixed missing blobs in backfilling by @Giulio2002 in #11569

Full Changelog: v2.60.5...v2.60.6

v3.0.0-alpha2

Key features

alpha2 focuse on initial sync:

• Erigon becomes "Evergreen": it can download latest files even if you not using latest Erigon version
• We starting release files near chain-tip (10K-100K blocks)

Numbers from 128Gb RAM, 16CPU, NVMe machine:

If you have any perf problems on chain-tip - first please rm -rf chaindata - likely it will help. If not - report us issue.

alpha3 will focus on chain-tip perf and peak RAM usage.

Upgrade from Erigon3-alpha1

amoy - pleas re-sync. other chains can upgrade without re-sync.

Roadmap

Next release will focus on "chain-tip" performance and peak RAM reduction.

v2.60.5

Improvements:

• Diagnostics: snapshot stage info gathering by @dvovk in #11105
• support of hex-encoded Nonce in genesis.json and eth_feeHistory by @AskAlexSharov in #11264
• PIP-35: enforce 25gwei gas config for all polygon chains for erigon 2 by @manav2401 in #11295
• tracer: add support bailout on evm.create() on e2 by @lupin012 in #11259
• RPC throughput increase (mutex-contention reduce on block files) by @tholcman and @AskAlexSharov in #11155

Bugfixes:

• TxPool: prevent db grow by @AskAlexSharov in #11200
• Fix on logCount param management by @lupin012 in #11258

Full Changelog: v2.60.4...v2.60.5

v3.0.0-alpha1

Erigon3 user guide

RAM requirement is higher: 64gb. We will reduce it in next releases.

Golang 1.21

Almost all RPC methods are implemented - if something doesn't work - just drop it on our head.

Supported networks: all (except Mumbai).

E3 changes from E2:

• Sync from scratch doesn't require re-exec all history. Latest state and it's history are in snapshots - can download.
• ExecutionStage - now including many E2 stages: stage_hash_state, stage_trie, stage_log_index, stage_history_index,
  stage_trace_index
• E3 can execute 1 historical transaction - without executing it's block - because history/indices have
  transaction-granularity, instead of block-granularity.
• E3 doesn't store Logs (aka Receipts) - it always re-executing historical txn (but it's cheaper then in E2 - see point
  above). Known perf issues: #10747
• --sync.loop.block.limit is enabled by default. (Default: 5_000.
  Set --sync.loop.block.limit=10_000 --batchSize=2g to increase sync speed on good hardware).
• datadir/chaindata is small now - to prevent it's grow: we recommend set --batchSize <= 2G. And it's fine
  to rm -rf chaindata
• can symlink/mount latest state to fast drive and history to cheap drive
• Archive Node is default. Full Node: --prune.mode=full, Minimal Node (EIP-4444): --prune.mode=minimal

Known Problems of E3:

• eth_getLogs fields index always 0: #10324

E3 datadir structure

datadir        
    chaindata   # "Recently-updated Latest State" and "Recent History"
    snapshots   
        domain    # Latest State: link to fast disk
        history   # Historical values 
        idx       # InvertedIndices: can search/filtering/union/intersect them - to find historical data. like eth_getLogs or trace_transaction
        accessors # Additional (generated) indices of history - have "random-touch" read-pattern. They can serve only `Get` requests (no search/filters).
    temp # buffers to sort data >> RAM. sequential-buffered IO - is slow-disk-friendly
   
# There is 4 domains: account, storage, code, commitment 

E3 can store state on fast disk and history on cheap disk

If you can afford store datadir on 1 nvme-raid - great. If can't - it's possible to store history on cheap drive.

# place (or ln -s) `datadir` on slow disk. link some sub-folders to fast disk.
# Example: what need link to fast disk to speedup execution
datadir        
    chaindata   # link to fast disk
    snapshots   
        domain    # link to fast disk
        history   
        idx       
        accessors 
    temp   

# Example: how to speedup history access: 
#   - go step-by-step - first try store `accessors` on fast disk
#   - if speed is not good enough: `idx`
#   - if still not enough: `history`
