An unnamed source at Barclays says that the bank, along with UBS and BNP Paribas, are exploring Ethereum.

All three banks have already publicly disclosed their exploration of Bitcoin’s  Blockchain  Blockchain Blockchain comprises a digital network of blocks with a comprehensive ledger of transactions made in a cryptocurrency such as Bitcoin or other altcoins.One of the signature features of blockchain is that it is maintained across more than one computer. The ledger can be public or private (permissioned.) In this sense, blockchain is immune to the manipulation of data making it not only open but verifiable. Because a blockchain is stored across a network of computers, it is very difficult to tamper with. The Evolution of BlockchainBlockchain was originally invented by an individual or group of people under the name of Satoshi Nakamoto in 2008. The purpose of blockchain was originally to serve as the public transaction ledger of Bitcoin, the world’s first cryptocurrency.In particular, bundles of transaction data, called “blocks”, are added to the ledger in a chronological fashion, forming a “chain.” These blocks include things like date, time, dollar amount, and (in some cases) the public addresses of the sender and the receiver.The computers responsible for upholding a blockchain network are called “nodes.” These nodes carry out the duties necessary to confirm the transactions and add them to the ledger. In exchange for their work, the nodes receive rewards in the form of crypto tokens.By storing data via a peer-to-peer network (P2P), blockchain controls for a wide range of risks that are traditionally inherent with data being held centrally.Of note, P2P blockchain networks lack centralized points of vulnerability. Consequently, hackers cannot exploit these networks via normalized means nor does the network possess a central failure point.In order to hack or alter a blockchain’s ledger, more than half of the nodes must be compromised. Looking ahead, blockchain technology is an area of extensive research across multiple industries, including financial services and payments, among others.

The source told International Business Times UK that while the three banks are currently the front runners in working with Ethereum, their research is not "in any great depth."

"You are talking about 100 or 200 people that are building stuff with this and some of them are from banks," the source said, adding, "It's the beginning. It's not even the end of the beginning. It's the beginning of the beginning."

Ethereum formally launched its platform last week, releasing a command line version of its first tool, Frontier. “What bitcoin does for  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. Most commonly the basis of exchange involves fiat currency or legal tender, be it in the form of cash, credit or bank transfers, debit, or checks. While typically associated with cash transfers, payments can also be made in anything of perceived value, be it stock or bartering – though this is far more limited today than it has been in the past.The Largest Players in the Payments IndustryFor most individuals, the payments industry is dominated currently by card companies such as Visa or Mastercard, which facilitate the use of credit or debit expenditures. More recently, this industry has seen the rise of Peer-to-Peer (P2P) payments services, which have gained tremendous traction in Europe, the United States, and Asia, among other continents.One of the biggest parameters for payments is timing, which looms as a crucial element for execution. By this metric, consumer demand incentivizes technology that prioritizes the fastest payment execution.This can help explain the preference for debit and credit payments overtaking check or money orders, which in previous decades were much more commonly utilized. A multi-billion-dollar industry, the payments space has seen some of the most innovation and advances in recent years as companies look to push contactless technology with faster execution times.

Read this Term, Ethereum does for anything that can be programmed,” according to its creators.

However, the source noted that there are drawbacks with Ethereum, such as the difficulty to debug applications built on it. Ethereum may be working on another version of its platform that is “more amenable” for banks. At a briefing on Frontier’s launch, a spokesperson went as far as to claim that the platform was "the only game in town for banks looking to build blockchains."

The source also noted the “pockets of innovation” at Barclays- some are working on promoting “social good”, while others, such as in the investment bank, are working on creating efficiency.

The approach taken in working with 'Bitcoin 2.0' technologies like Ethereum follows that of parallel projects: development would be of the not-for-profit, open source variety. It would require the collaboration of several institutions. "The whole value proposition here depends on banks being open and working together," he said. However, "They don't really do this. They seem to be worried about being competitive. Whatever reason they give is bo***cks."

He claimed that “most banks are just looking at Bitcoin technology; most of them have developed coins,” noting the irony that at the same time, many are unwilling to offer banking services to Bitcoin businesses.

One coin being experimented with is “govcoin”, which may help authorities save £4-5 billion in annual benefits overpayments and fraud.

"The floodgates are waiting to be opened," he said.
