Wall Street’s tokenization rollout just went live. 🏛️ @The_DTCC has launched its service on @CantonNetwork and Besu, with 20 firms signed up and @OndoFinance among its ecosystem collaborators.

DTCC picks Canton for launch, Stellar and Arc for 2027 DTCC (@The_DTCC) will launch its Tokenization Service this month on the @CantonNetwork and Besu, DTCC's private network. It starts with 25 stocks, ETFs, and US Treasuries, tokenized 1:1 with securities held at DTC and transferable 24/7 between registered wallets. DTCC puts the pool of assets available to tokenize at about $30 trillion. @StellarOrg and Circle’s @arc are expected to join in 2027, per DTCC’s roadmap, which it says may still change.

Three of the largest G-SIBs and the world's three largest CSDs use LFDT technologies. A new @LedgerInsights report, commissioned by LFDT, maps 80 institutional platforms: #LFDT# #opensource# @Besu_eth

Consensys is heading to @Sibos Miami. @mkriak and @davebarna will be meeting with financial institutions to discuss how they can benefit from Ethereum, Linea and Besu. If you’ll be at Sibos, get in touch with Mike and Dave to connect in Miami. 📍 Miami 📅 28 Sept - 01 Oct

Using the methodology behind CertiK’s Chain Scan initiative, our team independently uncovered five resource-exhaustion vulnerabilities in @Besu_eth, including two rated Major. All five were responsibly disclosed and patched in v26.7.1. Read the research ↓

Meet Roman, one of our Engineer at @Consensys & @LineaBuild. Roman works on Lineth across: the Coordinator that sequences transactions and orchestrates proving, Maru the consensus client, the rollup guest programs, and some of the Lineth Besu plugins that tie the stack to the client underneath it. In this Developer Showcase interview he explains what it means to build Lineth in the open within the @lfdecentralized community.

🚨 @The_DTCC's Tokenization Service went live today: - 34 securities available to tokenize at launch - DTCC didn't publicly disclose which ones, but said they'd come from select large-cap Russell 1000 stocks, select ETFs and US Treasuries - Each token is backed 1:1 by a security held at DTC with the same legal rights - Tokens can move 24/7 between DTC-registered wallets @CantonNetwork and DTCC's private Besu network are live at launch, with @StellarOrg and Circle's @Arc expected in 2027. For context, DTC has about $30 trillion in assets under custody.

DTCC ran live tokenised stock and treasury trades with JPMorgan, BlackRock and Goldman on 15 July. Nearly 40 firms took part. The standout moment: JPMorgan tokenised shares of the Invesco QQQ ETF, posted them as collateral to meet a margin call at CME Group, then converted them back. A central counterparty accepted tokenised assets as margin — for the first time. Pilots settled on Hyperledger Besu and the Canton Network. 📷 Listen to the latest episode on
