Ernst & Younger revealed an enterprise contract administration service that will let purchasers put contracts on a public blockchain whereas retaining enterprise info non-public via zero-knowledge circuits. The agency markets its OpsChain Contract Supervisor as operating on Ethereum, though it at present runs on Polygon proof-of-stake (PoS).
The accounting agency — one of many “large 4” alongside Deloitte, KPMG, and PwC — has been toying with enterprise implications for zk proofs since no less than 2018. The announcement could present one other concrete step towards the institutional use of public blockchains, a month after asset administration large BlackRock launched a tokenized fund on Ethereum.

In a press launch, EY mentioned the service would convey enterprise agreements to Ethereum, however this isn’t precisely the case. Dusk, the zero-knowledge rollup EY developed to do issues like handle enterprise contracts, really runs on Polygon PoS, an unbiased blockchain.
EY Blockchain plans to maneuver Dusk to Ethereum mainnet and to a layer-3 in Dusk’s subsequent improve, Paul Brody, who has led EY’s blockchain arm since 2016, mentioned.
Brody, reached via a spokesperson, added that Dusk was developed on Ethereum and is deployed to Ethereum’s take a look at community, however to date, EY’s industrial customers have been drawn to Polygon for its low transaction prices.
Personal blockchains aren’t non-public
In a previous profession cease, Brody was partly chargeable for constructing IBM’s first blockchain based mostly on the alpha model of Ethereum with the assistance of Ethereum co-founder Vitalik Buterin, Brody advised Blockworks in an interview.
Utilizing blockchain expertise for enterprise isn’t a brand new concept. In earlier days of Bitcoin and blockchain, teams just like the Distributed Ledger Group sprang as much as discover methods for companies to utilize distributed ledger expertise, usually utilizing non-public blockchains.
This period of so-called enterprise blockchain has largely fallen out of focus for crypto’s vanguard. Brody mentioned a future for blockchain functions for large enterprise will lie on public blockchains like Ethereum.

“The issue with non-public blockchains is that they don’t really present privateness,” Brody mentioned. “Folks jumped into this with out actually understanding the expertise, and it was solely after they received into it that it’s like, ‘Oh, all people within the non-public chain can nonetheless see every little thing.’”
Personal blockchains saved rivals from working collectively partly as a result of they might reveal delicate info like, as an example, the amount and costs of a enterprise’s purchases, Brody defined.
Alongside Dusk, EY additionally created Starlight, a zero-knowledge compiler that takes current sensible contracts and privatizes them with hashing.
With these instruments, EY will begin letting companies execute enterprise contracts utilizing Polygon’s sensible contracts. Dusk is just accessible to enterprises. The testnet is free, and the complete product is priced by EY, Brody mentioned, including that utilizing a public blockchain makes the deployment price cheaper for enterprise functions, for the reason that underlying infrastructure is already constructed.
A promotional doc for the contract supervisor says EY’s product “revolutionizes how enterprises assist handle their contracts by harnessing privacy-enabled blockchain expertise to streamline processes and improve transparency.”
