R3 releases Corda as blockchain strains start to show

Even as some original founders withdraw from the R3 consortium of banks developing blockchain proofs of concept, it opens up what could become a key piece of infrastructure for the future of wholesale financial services.

R3, the financial innovation firm attempting to coordinate a multitude of efforts among a 70-strong consortium of banks and buy-side firms to develop blockchain-based wholesale financial services, released Corda on Wednesday.

This is the distributed ledger platform, jointly developed by leading IT system architects at many of the world’s largest banks, which they hope will be a key underpinning in future for much cheaper and more secure transfer of all manner of financial and other assets.

A key aspect of Corda’s release is that R3 grants the global developer community universal access to its source code so as to encourage collaboration, review and contribution to the platform.

Richard Gendal Brown, chief technology officer at R3, whose hire last year from IBM was pivotal in the consortium quickly gaining credibility, discussed some of the key differences between the bitcoin blockchain that first seized the imagination of bankers in 2015 and the Corda distributed ledger they have now helped to build.

He told a DTCC-sponsored London forum on disruptive technologies on Tuesday: "I call Corda not a blockchain but a distributed ledger or sometimes a decentralized database because it allows counterparties who know each other and who trust each other enough to trade – but perhaps not enough to have the other side manage their own internal books and records – to come to consensus about certain shared facts that are important to them, such as details of a transaction, say, or margin requirements on a deal, very quickly and efficiently."

Corda is, therefore, very different from the bitcoin blockchain that first inspired it. That operates in an unregulated marketplace where no one trusts anyone, identities are hidden behind pseudonyms and proof of work is required to achieve broad consensus to validate each transfer of tokens and agree who owns what.

By contrast, Corda has been developed for a regulated wholesale financial market and is designed to allow different approaches to consensus for different asset classes.

Crucially, financial agreements on Corda take the form of smart contracts, linking business logic and data to associated legal prose to ensure the trades on the platform are rooted firmly in law.

Not everyone needs to see everything and the design is such that details might be confirmed only between nodes on a network that are the actual counterparties to a particular transaction and perhaps to regulators as well, or central market authorities that require trade confirmation.

David Rutter, CEO of R3, comments: "The applications being built therefore need to be based on common, open, interoperable platforms – much like the common protocols on which the internet operates today. Open sourcing Corda is the next step in making Corda one of these platforms."

R3’s Brown says, in the early stages of technology development: "I agree that premature standardization is almost always a mistake, but we have tried to standardize where we can." Where for example? "Corda is open source, but with agreed standards for licensing the underlying code."

This is part of the effort to open up Corda as a platform on which vendors’ and banks’ own coders might in future develop different protocols for transferring, confirming and settling flows not just in financial assets but also in hard assets and in data, such as know-your-customer identity checks.

The release of Corda comes after a torrid few weeks for R3 in which a number of the first wave of banks that founded the consortium decided not to renew their $100,000 annual membership fees. The biggest intrigue centres on the decision of Goldman Sachs not to renew, while it appears Santander has also decided not to, as well as later joiners including Morgan Stanley and National Australia Bank.


These decisions come as sources tell Euromoney R3 is in the midst of restructuring an institutional funding round in which it hopes to raise $150 million mainly from consortium members. The target size has been cut from the $200 million first mooted in the summer, with the ownership percentage to be divided between consortium banks also cut, reportedly from 90% to 60%.

These sources see two different forces at work behind the recent high-profile departures from R3.

The first is the traditional power struggle familiar to any consortium of banks that want to work together on a particular market structure project while still competing ruthlessly in the same business line.
