The intermingling of public and private ledgers emerged as a key narrative in enterprise blockchain discussions at CoinDesk’s Consensus 2019 conference.
At the three-day event, which wrapped up Wednesday, heavyweight companies and infrastructure providers alike could be seen plotting a spectrum of blockchain strategies. Some were new entrants to the space, others were stalwarts, but these were the five storylines that shaped the enterprise conversation at the industry’s biggest conference.
So-called “Blockchain-as-a-Service” was front and center this year, with Amazon Web Services (AWS) taking to the stage at Consensus for the first time to talk about its new Managed Blockchain Service, which deploys Hyperledger Fabric with public ethereum soon to be added.
AWS was also there to talk about its Quantum Ledger Database (QLDB), a centrally administered immutable data ledger, which Gartner predicts could eat up a sizeable chunk of the enterprise blockchain space.
This is likely to happen as companies realize they don’t need so much in the way of distributed consensus or tokenization, Gartner said, but really just an immutable system of record. (By 2021, at least 20 percent of projects envisioned to run on permissioned blockchains will instead run on centralized auditable ledgers.)
Rahul Pathak, general manager of AWS Managed Blockchain Services, chose not to speculate on whether Gartner’s claims might be accurate, but he did confirm the rumor that QLDB started life not as an alternative to permissioned chains, but rather as an internally developed tool with Amazon’s vast retail business.
“We have a very long and healthy tradition of bringing forward internally developed projects at Amazon.”
