More than half of the world’s large corporations are looking into blockchain (distributed ledger technology), according to a study by U.K. research firm Juniper Research.

The research, released on Monday, found that 57 percent of large corporations – defined as any company with more than 20,000 employees – were either actively considering or in the process of deploying blockchain.

And two-thirds of companies surveyed by Juniper said that they expected the technology to be integrated into their systems by the end of 2018.

“It is clear that companies across the board have a significantly greater understanding of blockchain technology than was the case 12 months ago,” the report said.

“This stems in part from a surge in R&D (research and development) both internally and in partnership with third parties, with a recognition that blockchain has the potential to be deployed in a variety of use cases.”

The report added: “As the number of research projects has increased, so too has awareness, both amongst the participants and elsewhere in their industries, with competitor companies in turn beginning to consider whether they too should seek to gain competitive advantage from deployment.”

Blockchain is a form of distributed ledger technology (DLT). This means that it maintains records of all virtual currency transactions on a distributed network of computers, but has no central ledger.

The original blockchain network was created by bitcoin-founder Satoshi Nakamoto to serve as the public ledger for all bitcoin transactions.

In June, tech giant IBM was selected to build a blockchain-based international trading system for seven of the world’s biggest banks, including Deutsche Bank, HSBC, KBC, Natixis, Rabobank, Societe Generale and Unicredit.

It signaled one of the first cases of blockchain entering the mainstream for big financial institutions.

The research by Juniper also warned against using blockchain technology without first considering other alternatives.

“In many cases, systemic change, rather than technological, might be a better and cheaper solution than blockchain, which could potentially cause significant internal and external disruption,” Windsor Holden, the author of the research, wrote.

The research found that some companies underestimated the scale of challenge of deploying blockchain.

Survey respondents indicated progressive concern as their companies came closer towards full deployment. Concerns were also raised over clients refusing to embrace the technology.
