on GitHub

Description

Release v1.1.12 is a performance release. the following two features are introduced in this release.

1. Separate Processing and State Verification.
2. Pruning AncientDB inline at runtime.

Fast Node

Fast Node is introduced in #926, it is a new syncing protocol to lower the hardware requirement and improve the syncing efficiency.

This release introduces two types of nodes to make full use of different storage, one is called fast node, and the other is called verify node. The fast node will do block processing with a flattened key-value DB, it will do all verification against blocks except the state root. The verify node receives diffhash from the fast node and then responds MPT root to assist with the state root verification. If you want to learn more about this feature, please refer to the docs.

It turns out that the fast node can slow down the storage growth by 60%~90% according to different settings and increase the syncing efficiency by about 30%. We encourage node operators who do not care about 100% state consistency to enable fast nodes by appending --tries-verify-mode none to the node command.

Note: fast node can never revert to full node.

Pruning AncientDB inline at runtime

A new flag is introduced to prune ancient undesired block data at runtime, it will discard block, receipt, header in the ancient DB to save space.

Example: geth --config ./config.toml --datadir ./node --cache 8000 --rpc.allow-unprotected-txs --txlookuplimit 0 --syncmode full --pruneancient.

Note:

• once turned on, the ancient data will not be recovered again
• only under ‘--syncmode full’ mode supports --pruneancient flag

Removed

1. --yolov3
2. --vm.ewasm
3. --vm.evm
4. --rpc (use --http)

6. --rpccorsdomain (use --http.port)
7. --rpcvhosts(use --http.corsdomain)
8. --rpcapi (use --http.vhosts)

Added

1. --dev.gaslimit Initial block gas limit
2. --sepolia Sepolia network: pre-configured proof-of-work test network
3. --override.arrowglacier Manually specify Arrow Glacier fork-block, overriding the bundled setting
4. --override.terminaltotaldifficulty Manually specify TerminalTotalDifficulty, overriding the bundled setting
5. --rpc.evmtimeout Sets a timeout used for eth_call (0=infinite)
6. --gpo.ignoreprice Gas price below which gpo will ignore transactions
7. --metrics.influxdbv2 Enable metrics export/push to an external InfluxDB v2 database
8. --metrics.influxdb.token Token to authorize access to the database (v2 only)
9. --metrics.influxdb.bucket InfluxDB bucket name to push reported metrics to (v2 only)
10. --metrics.influxdb.organization InfluxDB organization name (v2 only)

Changed

1. --syncemode removed the fast mode
