Playing with blockchain

Although not presently in widespread use, blockchain has great potential to transform transaction processing across the economy – particularly for participants in the banking, financial services and retail sector.

 

The largest and most famous blockchain in use today is Bitcoin. But for many businesses a private or a public / private hybrid using blockchain promises to improve business operations. Blockchain is a transparent, electronic ledger in which transactions are recorded, mined and reviewed by participants. A blockchain shows that a transaction happened, when it happened and – upon consensus – that it happened correctly, without exposing confidential, identifiable details, including party identity and asset subject.

 

By storing transaction data in chronological order – or “chaining” it – rather than overwriting pre-existing iterations of a deal, it becomes far harder to change deal terms without the knowledge of all transaction participants. New proposed blocks are available for review by all parties. Only upon approval of the terms by a new party is a new block added to the chain, changing the original transaction. This reduces the likelihood of fraud within the network.

 

Challenges & Challenges

 

Blockchain - case studiesBlockchains, in order to work, must build trust between partners. Without that trust, participants are often unwilling to join, significantly diminishing the “power in numbers” benefits that make blockchain systems work. Moreover, immature and evolving technology standards, complications related to intra- and extra-enterprise connection and collaboration, ill-defined regulatory views of transaction legality and encryption and security concerns serve as significant barriers to rapid blockchain adoption.

 

However, when these and other challenges are overcome, all transactions within the blockchain network become transparent to all parties, making a central clearing house unnecessary. By exercising the power of the network for validation in lieu of central clearing house, blockchain stands to benefit participants in numerous ways, including increasing settlement speed, improving operational efficiency through increased digitalization, improving audit processes through review of stored blocks, reducing risk of fraud and reducing transaction costs. In short, blockchain has the potential to speed business, reduce costs and losses and improve efficiency.

 

Blockchain Investments

 

As a result of perceived market advantages to its use, blockchain development and investment is moving rapidly. According to PricewaterhouseCoopers (PwC) 1.4 billion dollars were invested in blockchain startups during the first 9 months of 2016.

 

Because of perceived competitive advantages, including reduced costs, faster transaction settlement times and improved transactional accuracy, traditional banking and financial services institutions are particularly interested in blockchain. As a result, 90% of major banks in the United States, Canada and Europe are exploring blockchain technology, with 30% involved in developing proof-of-concept systems related to intra- and inter-bank transfers, corporate payments and person-to-person transfers.
