VMware Research is actively participating in advancing blockchain technology to provide the most secure, reliable, and scalable blockchain platforms.
Concord SBFT released and open sourced on Github!
Project Concord is a highly scalable and energy-efficient distributed trust infrastructure for consensus and smart contract execution.
The core engine of project Concord is concord-bft, a generic state machine replication library that can handle malicious (byzantine) replicas. This library is designed to be used as a core building block for replicated distributed data stores, and is especially suited to serve as the basis of permissioned Blockchain systems. Its implementation is based on the algorithm described in the paper SBFT: a Scalable Decentralized Trust Infrastructure for Blockchains.

In order to remove existing barriers for adoption, there is a clear need for building robust and secure high-throughput, high capacity distributed ledger technologies that rely on careful distributed-system design and strong engineering.
Our unique vision centers around five points:
permission, private distributed ledgers, not Proof-of-Work.
high-throughput data replication, not quorum-based.
a world of many ledgers , not a global database.
seamless core cross-ledger transaction support, no escrow required
built-in reconfiguration capability and membership, not just authX/authZ
Atop a distributed ledger, which is the "ground truth" from which information is drawn, the fintech disruption occurs at two additional levels: Contracts, and Services.
Contracts: Broadly speaking, Contracts are formats for expressing secure business transactions. Contracts leverage the underlying ledger and anchor within ledger blocks. There is a growing interest in utilizing the protocol framework for a variety of use-cases. One is carrying direct business-to-business deals without involving a trusted third party. Another is to assume there is a settlement agency involved, and use Contracts to facilitate a fast turnaround and versatility in expressing transactions.
Services: Having a Blockchain of transactions opens access to data which was not accessible before. There are a lot of potential services and applications that can be built to make use of the data: Business analytics, prediction tools, personal management apps, identities, and many many more.
Announcing: Decentralized Cryptocurrencies and Blockchains 2018
