@gzliudan gzliudan force-pushed the abstract-node-scheme branch from fa79eb3 to add6411 Compare June 19, 2025 10:13
@gzliudan gzliudan changed the title [WIP] core, eth, trie: abstract node scheme #25532 core, eth, trie: abstract node scheme #25532 Nov 12, 2025
This PR introduces a node scheme abstraction. The interface is only implemented by `hashScheme` at the moment, but will be extended by `pathScheme` very soon.

Apart from that, a few changes are also included which is worth mentioning:

-  port the changes in the stacktrie, tracking the path prefix of nodes during commit
-  use ethdb.Database for constructing trie.Database. This is not necessary right now, but it is required for path-based used to open reverse diff freezer
