* histor. batch proof: make best block arg optional
* correct testing range
* make generate_batch_proof stub for historical
* merge generate_{historical_}batch_proof functions
* merge generate_{batch_}proof functions
* merge verify_{batch_}proof functions
* merge verify_{batch_}proof_stateless functions
* remove {Leaf}Proof
Not utilized by API anymore, so superfluous.
Removal consistent with prior changes to just use "batch" proof API.
* rename BatchProof->Proof
no need to qualify if only one universal proof type.
* cleanup
* expose verify_proof rpc api
* document verify_proof
* expose verify_proof_stateless rpc api
* add optional BlockHash to mmr_root rpc api
* fixup! expose verify_proof rpc api
* fix documentation phrasing

Substrate ·

Substrate is a next-generation framework for blockchain innovation 🚀.
Getting Started

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
