Hyperledger Burrow
A permissioned Ethereum smart-contract blockchain node
...Burrow provides transaction finality and high transaction throughput on a proof-of-stake Tendermint consensus engine. Burrow is a fully-fledged blockchain node and smart contract execution engine -- a distributed database that executes code. Burrow runs Ethereum Virtual Machine (EVM) and Web Assembly (WASM) smart contracts. Burrow networks are synchronized using the Tendermint consensus algorithm. A node can detect if its state is corrupted or if a validator is dishonestly executing the protocol. Run a private or public permissioned network. Stakeholders may vote for autonomous smart contract upgrades. ... -

LBRY Chainquery
Chainquery parses and syncs the LBRY blockchain data
...While the blockchain is the innovation that makes LBRY possible, the Data Network is the layer that actually makes the blockchain useful. The job scheduler schedules different types of jobs to update the Chainquery database example. These jobs synchronize different areas of the data either to make queries faster or ascertain information that is not directly part of the raw blockchain. The example provided is leveraged to handle the status of a claim which is actually stored in the ClaimTrie of LBRYcrd. So it runs periodically to make sure Chainquery has the most up-to-date status of claims in the trie. -

BlockSci
A high-performance tool for blockchain science and exploration
...But that’s unnecessary for blockchain analysis where the data structures are append-only. We take advantage of this observation in the design of our custom in-memory blockchain database as well as an analysis library. BlockSci’s core infrastructure is written in C++ and optimized for speed. (For example, traversing every transaction input and output on the Bitcoin blockchain takes only 1 second on our r5.4xlarge EC2 machine.) To make analysis more convenient, we provide Python bindings and a Jupyter notebook interface. -
