Commonwealth Bank has built a &#39;working blockchain&#39;

Two of Australia's big four banks are taking steps to bring their blockchain ambitions closer to reality, according to Australian Financial Review. Commonwealth Bank of Australia (CBA) has built a 'working blockchain' in its Innovation Lab by putting together five 1-gigabyte computer boxes and loading them up with ledgers and keys. Each of the five computers represent a 'node' in the dummy blockchain and will host a distributed ledger to validate transactions rather than through one central party. It will, for the first time, allow CBA customers, regulators and bank employees to see for themselves how the blockchain works in practice. Westpac, another of the big four banks, is this week holding a 'blockchain design challenge', where developers will hear about the technology’s potential from senior technology executives, bankers and lawyers.

Commonwealth Bank of Australia (CBA) literally built a blockchain. According to Australian Financial Review, CBA put together five 1 GB computer boxes and loaded them up with ledgers and keys. Each computer represents a node in the dummy blockchain and would host a distributed ledger to validate transactions.

It reportedly took the bank's IT team two weeks to build the code for the scheme.

Bitcoin's blockchain and other distributed ledger systems inspired by it are envisioned to change the way banks settle securities and Payments Payments One of the bases of mediums of exchange in the modern world, a payment constitutes the transfer of a legal currency or equivalent from one party in exchange for goods or services to another entity. The payments industry has become a fixture of modern commerce, though the players involved and means of exchange have dramatically shifted over time.In particular, a party making a payment is referred to as a payer, with the payee reflecting the individual or entity receiving the payment.

CBA earlier this year announced plans to adopt the Ripple protocol for currency transfers. It was also one of the first banks to join a startup-led consortium that aims to develop blockchain technology in collaboration.

On the surface, it would seem that Australian banks have a love-hate relationship with cryptocurrency. They have been proactive with their blockchain technology endeavors, and CBA CIO David Whiteing even hinted that the cryptocurrencies themselves aren't so bad.

On the other hand, Australia's banks have also reportedly been closing the accounts of bitcoin startups, and the country's competition watchdog reportedly began investigating.

Another one of the big four, Westpac, is holding a "blockchain design challenge", which will bring together developers, technology executives, bankers and lawyers. Westpac too announced plans to explore Ripple earlier this year, and was disclosed as one of the investors behind Coinbase's record-breaking $75 million funding round.
