SBI backs institutional blockchain infrastructure

SBI Holdings disclosed on May 21 that it led an investment round in Temple Digital Group, a New York company building trading infrastructure on the Canton Network blockchain. SBI said the investment was made through a subsidiary and identified Temple Chief Executive Evan Varsamis and Chief Strategy Officer Dan Simerman in the announcement. Temple said the round comes as it expands a product suite built around private, compliant trading and settlement infrastructure for institutional users. On its website, the company describes itself as a trading, liquidity and asset-issuance platform powered by Canton, and said this week it is preparing to list regulated markets in the second half of 2026. ### Why does SBI’s backing matter here? (sbigroup.co.jp) SBI Holdings is one of Japan’s most active financial groups in digital assets, so its participation gives Temple a strategic sponsor with an established institutional footprint. SBI’s filing described Canton as a blockchain foundation for institutional investors and framed Temple as a provider of institutional trading infrastructure on that network. (templedigitalgroup.com) May 20 was the date Temple published its own account of the round, saying it was taking on new capital as it expands products and prepares regulated market listings later this year. Temple also said it is among the leading applications on Canton by network revenue, a claim made in its company announcement. ### What exactly is Temple building? (sbigroup.co.jp) Temple says its stack is aimed at capital-markets use cases rather than retail crypto trading. The company’s site says it offers compliant, private infrastructure with trading, vaults, and SDK and API tools, while earlier company materials said it was building a privacy-focused technical stack to trade capital markets on Canton. January 2026 brought Temple’s launch of a 24/7 institutional trading platform on Canton, according to reports indexed in search results, with non-custodial trading and central-limit-order-book style functionality described as part of the platform. (templedigitalgroup.com) Those descriptions align with Temple’s broader pitch around real-time settlement and composability across financial applications.

Its website says orderbooks are a native primitive, and a recent Dune announcement described the network as designed for ultra-low latency, high throughput and full EVM composability for spot, perpetual and other orderbook-based markets. RISE marketing materials cite about 1 millisecond latency, more than 50,000 transactions per second and native shared orderbooks. (ainvest.com) A Gelato profile of the project said the network is trying to match centralized-exchange performance while keeping Ethereum-based security and composability. ### Are Temple and Rise solving the same problem? Temple and RISE are aimed at adjacent layers of market infrastructure rather than the same product slot. (risechain.com) Temple is positioning itself around institutional market access, privacy, compliance and settlement on Canton, while RISE is promoting an execution environment for fully onchain orderbook markets on Ethereum infrastructure. That comparison is an inference from the companies’ public descriptions of their products. (risechainmomo-phi.vercel.app) Canton’s pitch centers on privacy and institutional interoperability, while RISE’s pitch centers on speed, shared state and orderbook-native execution. Both are targeting financial-market plumbing, but they emphasize different technical constraints in their public materials. ### What should readers watch next? The second half of 2026 is Temple’s stated window for listing regulated markets, according to its May 20 announcement. (templedigitalgroup.com) SBI has not publicly disclosed the size of the round in the materials reviewed, but Temple’s next visible milestone is those planned listings. RISE’s near-term benchmark is whether developers and market operators adopt its orderbook-focused infrastructure beyond promotional claims. (sbigroup.co.jp) For now, the most concrete public markers are its live network materials, Dune integration and published latency and throughput targets. (dune.com) (templedigitalgroup.com)
