The deal is likely to be formally announced within the next six months, but financial terms are still unclear, the people said.
Around 25 people currently work on the Quorum team globally, and it is unclear whether they will join ConsenSys after the merger, the people said.
Blockchain emerged over a decade ago as the software tracking cryptocurrency transactions. Since then, banks and other large corporations have been investing millions of dollars to develop and test a range of business applications using the nascent technology. Efforts have had mixed results, with few projects achieving significant impact.
JPMorgan built the Quorum blockchain internally using the ethereum network, the software that underpins ether, one of the most well known cryptocurrencies.
It is being used by JPMorgan to run the Interbank Information Network, a payments network that involves more than 300 banks. JPMorgan, the largest U.S. bank by assets, also said it would use Quorum to issue a digital currency called JPMorgan Coin that it designed to make instantaneous payments using blockchain.
A merger with ConsenSys would have no impact on the IIN and other JPMorgan projects running on Quorum, one of the people said.
JPMorgan has been considering spinning off Quorum for around two years, evaluating options including setting up an open-source foundation, creating a new startup or merging it with another company, the person said.
A merger with ConsenSys was chosen as the best path forward as both organizations work with ethereum and have been involved in joint initiatives in the past.
ConsenSys, a prominent blockchain startup that grew rapidly during the 2017 crypto bubble, was founded by Joe Lubin, one of the co-founders of ethereum. The company announced last week that it had laid off around 14% of its staff, as it undergoes a restructuring to separate its software development business from its venture activities.
A merger with Quorum would align with its shift toward growing its software division.
Quorum is open source, meaning its code is free and may be modified and redistributed. The plan after the merger is to maintain the Quorum brand and keep the technology open source, one of the people said.
