The latest v1.1.12 is a performance release. The following three features are introduced in this release.
Fast Node
Fast Node 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 to 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.
Pruning AncientDB 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.
Merge Go-Ethereum V1.10.15
We upgrade the code base of Go-Ethereum from v1.10.3 to v1.10.15. A lot of new features, bug fixes, library upgrades, as well as some breaking changes from Go-Ethereum are merged to BSC v1.1.12.
