## Description
Cannon's memory is currently structured as a binary merkle tree of depth 27 with 32 byte leaf values, representing a 32-bit address space. There are some performance bottlenecks wit…

### Summary
IBC Clients require a means of verifying parts of state of a counterparty chain. This is usually done in two steps 1) Verify the state root from a previous one 2) verify some set of dat…

Merkle (Patricia) tree proofs essentially prove that a certain element (or several elements) belongs to a certain data collection (list in the case of Merkle trees; map in the case of MPTs). Essential…

The section [Data Validation](https://nemtech.github.io/concepts/data-validation.html) describes Merkle trees data validation bu doesn't explain yet how Merkle **Patricia** Trees can be used to verify…

We need exhaustive tests for various corner cases of merkle patricia trie proofs to exercise this code here: https://github.com/near/rainbow-bridge/blob/master/libs-rs/eth-prover/src/lib.rs#L177-L315

It'd be often helpful for debugging if the state test runner would optionally (e.g. given a `--dumpState` flag) print either the full post state (all accounts in trie and their storages) or the state …
