The early promise of blockchain is beginning to bear fruit as financial services firms invest in DLT projects to reduce risk and cost.

The growth in popularity of privately issued digital currencies, most of which are cryptocurrencies like Bitcoin and Ethereum, has taken the world by surprise and highlighted many other uses for the "blockchain" distributed ledger technology (DLT) that underpins them.

Blockchain is a decentralized external ledger that records and verifies digital currency transactions, using encryption to secure their validity. The Bank of England, Sweden's central bank and the Bank for International Settlements (BIS) have all published papers exploring the feasibility of central bank-issued digital currencies - government-backed "fiat" money that would compete with private cryptocurrencies.

Banks, asset managers, insurers, financial market infrastructures and venture capitalists are all investing heavily in blockchain projects that seek to provide new financial services as well as deliver old ones more efficiently.

Martin Arnold, Banking Editor of the Financial Times, says "blockchain is the hottest buzzword in the financial sector". "Financial institutions are setting up consortiums of like-minded companies and carrying out proofs-of-concept to test the potential of the new technology," he says.

"There's an awful lot of activity and excitement. Some of the areas of banking I have seen most progress in are clearing and settlement, payments, trade finance and syndicated loans."

"There are cool things going on, like the World Wildlife Fund exploring DLT for tracking endangered species, and the former drummer of Guns N' Roses using it to collect music royalties. Its uses are being explored for shipping, supply chain management, food safety and identity management."

In finance, the greatest potential lies in areas "where data is more sensitive, where the management of assets and liabilities is not as automated as it could be, where speed is important, and where there is a multilateral workflow between companies," adds Mr Levy.

"The promise of blockchain is helping you move beyond your firewall, letting data flow in the ether, safely and securely. It is also where there is a heavy interaction with cash, in terms of reconciliation, in areas like loans, OTC derivatives, collateral management and repo."

IHS Markit is developing a blockchain-based system to handle payments in syndicated loan trading. Called Stax, it should reduce the complexity of cash transactions and reconciliation between parties in a syndicated loan.

Richard Crook, Head of Emerging Technology at RBS, says that a big advantage of DLT is that it is an open technology. "No single vendor has ended up owning it. That's a great thing," he says.

The fact that it can be complicated does not matter to users. "Most people don't know what TCP/IP internet protocols are but they use the internet. They might not know how GPS navigation works, but they use it," says Mr Crook.

Rhian Lewis, Co-Founder of CountMyCrypto and London Women in Bitcoin, agrees. "The point at which blockchain will become mainstream will be the point at which people don't know they are using it."
