JavaDB

  •    Java

Tendermint - Tendermint Core (BFT Consensus) in Go

  •    Go

Tendermint Core is Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language - and securely replicates it on many machines.

orbit-db - Peer-to-Peer Databases for the Decentralized Web

  •    Javascript

OrbitDB is a serverless, distributed, peer-to-peer database. OrbitDB uses IPFS as its data storage and IPFS Pubsub to automatically sync databases with peers. It's an eventually consistent database that uses CRDTs for conflict-free database merges making OrbitDB an excellent choice for decentralized apps (dApps), blockchain applications and offline-first web applications. All databases are implemented on top of ipfs-log, an immutable, operation-based conflict-free replicated data structure (CRDT) for distributed systems. If none of the OrbitDB database types match your needs and/or you need case-specific functionality, you can easily implement and use a custom database store of your own.

iSQL-Viewer - JDBC compliant database front end

  •    Java

iSQL-Viewer is JDBC compliant database front end. It implements across multiple platforms features of the JDBC API. It does everything through a single interface. iSQL-Viewer works with most database platforms, including PostgreSQL, MySQL, Oracle, and Informix.

Rippled - Decentralized cryptocurrency blockchain daemon implementing the XRP Ledger in C++

  •    C++

Ripple is a network of computers which use the Ripple consensus algorithm to atomically settle and record transactions on a secure distributed database, the Ripple Consensus Ledger (RCL). Because of its distributed nature, the RCL offers transaction immutability without a central operator. The RCL contains a built-in currency exchange and its path-finding algorithm finds competitive exchange rates across order books and currency pairs.


catena - Catena is a distributed database based on a blockchain, accessible using SQL.

  •    Swift

Catena is a distributed database based on a blockchain, accessible using SQL. Catena timestamps database transactions (SQL) in a decentralized way between nodes that do not or cannot trust each other, while enforcing modification permissions ('grants') that were agreed upon earlier. A Catena blockchain contains SQL transactions that, when executed in order, lead to the agreed-upon state of the database. The transactions are automatically replicated to, validated by, and replayed on participating clients. A Catena database can be connected to by client applications using the PostgreSQL wire protocol (pq).

ydn-db - Javascript database module for Indexeddb, Web SQL and localStorage storage mechanisms supporting version migration, advanced query, SQL and transaction

HyperGraphDB - Database for Storing Strongly-Typed Hypergraphs

  •    Java

HyperGraphDB is a general purpose, open-source data storage mechanism based on a powerful knowledge management formalism known as directed hypergraphs. While a persistent memory model designed mostly for Knowledge management, Artificial Intelligence and Semantic web projects, it can also be used as an embedded object-oriented database for Java projects of all sizes. It could also be used as graph database or as (non-SQL) relational database.

ScalikeJDBC - SQL-based DB access library for Scala developers

  •    Scala

ScalikeJDBC is a tidy SQL-based DB access library for Scala developers. This library naturally wraps JDBC APIs and provides you easy-to-use and very flexible APIs. What’s more, QueryDSL makes your code type-safe and reusable.

eos-go - EOS.IO Go API library

  •    Go

This library provides simple access to data structures (binary packing and JSON interface) and API calls to an EOS.IO RPC server, running remotely or locally. It provides wallet functionalities (KeyBag), or can sign transaction through the keosd wallet. It also knows about the P2P protocol on port 9876. As of before the June launch, this library is pretty much in flux. Don't expect stability, as we're moving alongside the main eosio codebase, which changes very fast.
