Dubbed ledgerconnect, the blockchain platform will offer applications and services provided by different vendors in areas such as customer compliance checks, sanctions screening and collateral management, the companies said.

LedgerConnect is similar to consumer app stores and should make it easier and cheaper for financial firms to use blockchain-based software.

Blockchain, which first emerged as the system underpinning cryptocurrency bitcoin, is a shared ledger of transactions that is maintained by a network of computers rather than a centralized authority. Banks and other financial institutions have been investing millions of dollars in developing the technology which they believe can help them simplify some of their processes and cut costs.

While many blockchain-based applications are being tested by banks, few have gone into production.

CLS and IBM hope that LedgerConnect can help speed up adoption by making blockchain-based software for financial firms more readily available, they said.

Building and testing each application individually by banks would be too costly and time consuming, they said.

CLS settles over $5 trillion of payment instructions a day for its members which include many of the world’s largest financial institutions such as Barclays and Citi.

“Barclays is participating in the LedgerConnect proof-of-concept so we can gain an understanding and experience of a new network for blockchain applications – and also test some candidate use cases on that network”, Lee Braine, from the chief technology office of Barclays’ investment bank, said in an email.

After the platform has been tested, and provided there is sufficient market demand, CLS and IBM hope to make it widely available to the industry.
