Joseph Lubin, Ethereum co-founder and head of ConsenSys, appeared on Bloomberg Crypto on October 7 and confirmed that ConsenSys is constructing a prototype for SWIFT’s new blockchain-based shared ledger. Introduced by SWIFT at Sibos in Frankfurt final week, the plan will add a permissioned, ever-running ledger to the worldwide messaging cooperative’s infrastructure and essentially combine ISO. 20022 Monetary Messaging.
SWIFT is constructed on Ethereum.
Lubin mentioned the primary construct “will most positively implement messaging, monetary messaging, utilizing ISO 20022.” Whereas SWIFT itself is “cautious to concentrate on the messaging half,” some collaborating banks are “enthusiastic about probably diving into the funds layer,” he added.
“You need to watch out about what I say. This can be a venture that we’re constructing. There will likely be technologists on their aspect and loads of technologists on our aspect. And I am glad you name it a prototype, as a result of that is what it’s,” the ConsenSys founder added.
He declined to offer a timeline for distribution. “I’ve an thought of what sort of timeline it’s and I can not say an excessive amount of about it. We’re defining what we imagine the ultimate state will likely be and we’re pulling again on that, so I do not know if SWIFT will likely be snug with releasing the timeline at this level,” Lubin mentioned.
SWIFT’s transfer, explicitly structured as a shared ledger that information, orders and verifies transactions, was revealed on September 29, with the cooperative saying the venture will present instantaneous 24/7 cross-border transactions on a worldwide scale whereas remaining asset-agnostic and interoperable with private and non-private networks, and “create a path to digital finance.” He emphasised that the purpose is to speed up the “transition.” The official materials didn’t specify the identify of the bottom chain, however did record ConsenSys as a key expertise companion and highlighted ISO 20022 compliance and sensible contract enforcement enterprise guidelines.
Within the Bloomberg interview, Lubin emphasised broader strategic modifications. In different phrases, the long-standing separation between “TradFi” and “DeFi” is breaking down. “Ever since Ethereum launched, we’ve got needed to keep in our personal orbit. The temper in Frankfurt was very totally different,” he mentioned, explaining the overwhelmingly optimistic financial institution suggestions and saying “it’s time for TradFi to merge or leverage DeFi.” He additionally characterised the present construct as a real prototype with expertise specialists “on their aspect and lots of on our aspect” and reiterated that SWIFT will management the messaging scope and the financial institution will discover deeper layers similar to atomic settlements.
What “Utilizing Ethereum” Actually Means
SWIFT didn’t formally specify the bottom chain in its press launch, however a number of business stories following Sibos and subsequent public feedback from Lubin point out that the prototype will run on Ethereum infrastructure, particularly ConsenSys’ Linea, an Ethereum Layer 2 community utilizing zero-knowledge proofs to fulfill banking compliance necessities. They mentioned they might deploy their builds throughout the Ethereum ecosystem whereas sustaining permissioned boundaries. These stories are per ConsenSys’ personal assertion that it “helps Swift with early-stage prototypes” for shared ledgers.
Institutional context issues. SWIFT’s ledger initiative comes amid the speedy progress of the $300 billion stablecoin market and a wave of financial institution tokenization pilots. The acknowledged design purpose is to not change present rails, however to increase them, permitting banks to decide on tokenized processes that enhance pace, transparency, and finality.
Past SWIFT: Rubin’s Treasury Paper
Lubin additionally used the Bloomberg phase to debate the rise of “digital asset-backed bonds” (DATs), such because the Ethereum-focused car he chairs at SharpLink. He argued that company ETH accumulation is a “volatility dampening issue,” described ETH as “a productive, yielding asset, not like Bitcoin,” when staking, and outlined a Berkshire-style flywheel the place the rising ETH base can be distributed throughout Ethereum-based protocols for non-dilutive progress.
The strategic path is evident. As monetary establishments standardize on Ethereum-based rails for messaging and funds, stability sheet ETH will change into a strategic asset for establishments looking for publicity to community exercise and yield.
At press time, ETH was buying and selling at $4,484.
