"Interop between permissioned Besu ledgers" isn't even 5% of a solution for what DTCC needs, which is why Chainlink is being used. What about interop to Solana? Tempo? Hyperliquid? Zero? Canton? Stellar? Arc? Canton, Stellar, and Arc are the actual *already* announced chains that DTCC’s tokenization service is expanding to (with many more to come). Besu has absolutely no way of enabling interop to where DTCC already confirmed they are launching. But on top of that, what about composability with non-financial networks like Fedwire, Fednow, Swift, DTCC, CLS, FIX, credit card networks, etc, which clear and settle transactions offchain? You need a protocol that can do "orchestration" to allow for bidirectional movement of data, value, and state sync with these off-chain systems. What about all the data needs? What about compliance? What about privacy? The goal of tokenization is to have synchronized data and value across many different chains *and* systems to enable regulated 24/7 markets with atomic DvP & PvP with T+ 0 settlement. "Interop between permissioned Besu chains" and/or intracluster connectivity within Ethereum L1 isn't even a 5% solution. Chainlink is the only protocol that *already* does: Data (Risk parameters, continuous price updates, NAV, Proof of Reserves, etc.) - Interoperability between all blockchains, public and private - Compliance (KYC/AML/Sanctions list, etc.) - Privacy (Confidential computations required to protect sensitive information) - Connectivity to existing financial systems (Swift, etc.) - Connectivity to AI Agents - and more Now you see how trivial a single blockchain is compared to the true problem. But it doesn't just end there. We've all these extra things to add into the transaction. Are we gonna use multiple separate solutions for each, each with their own architectures, security models, etc.? No, what we need is a fully verifiable, decentralized runtime environment to orchestrate everything a transaction needs. Enter the Chainlink Runtime Environment. Every single operation in a transaction (from the list of requirements above) is fully verifitable, tamper-proof, traceable, and auditable. The Chainlink Runtime Environment (CRE) is what orchestrates the full lifecycle of these transactions. Just look at the quotes from DTCC CTO and the slide from the workflow they just demoed at SWIFT's SIBOS conference. No blockchain even comes close to fulfilling this.
