It's been fascinating following JPMorgan's path into blockchains — they didn't tumble in all at once, it was a step-by-step build. The earliest piece most people point to is the Interbank Information Network (IIN), which quietly started in 2017 as a way for banks to share payment information and reduce friction. Then JPM Coin, which many headlines latch onto, was unveiled to the public in 2019 as a pilot for tokenized fiat transfers between institutional clients. Those two efforts, plus a few internal experiments, were folded into a more formal brand effort in 2020 when JPMorgan announced 'Onyx' — the corporate umbrella created to house and scale their blockchain and digital payments projects. The official Onyx announcement came around October 2020, and that’s the date most reports use for when the bank said, “we’re serious about doing blockchain at scale.”
After that formalization, Onyx kept iterating. Through 2021 and beyond they expanded pilots around tokenized cash, settlements, and digital asset services, and the group kept experimenting with things like wholesale digital currency prototypes and custody-related services. I followed a few deep-dive threads and articles back then and loved watching the shift: early experiments in 2017–2019, formal Onyx launch in late 2020, and then broader productization and pilots across 2021–2022. If you’re tracing precise milestones, think: IIN (2017) → JPM Coin pilot (2019) → Onyx branded launch/announcement (Oct 2020) → ongoing pilots and product work after that. It’s a gradual evolution rather than a single launch day.
If you want pointers for reading, I kept up with a mix of mainstream financial press and crypto trade outlets during the rollout — they capture both the corporate spin and the gritty tech details. For casual context, imagine a giant bank assembling its own internal toolkit across a few years and then giving it a proper name once the pieces were mature enough to run together. That’s essentially what happened with Onyx, and watching those separate experiments coalesce felt a bit like seeing a slow-building season premiere finally drop.
