Brazil’s biggest bank is taking another step into tokenized assets, adding to a growing list of the country’s financial heavyweights experimenting with putting traditional investments on blockchain rails. Itaú Unibanco has started working with digital-asset infrastructure provider OpenAssets on a tokenization pilot run by Brazilian Financial and Capital Markets Association ANBIMA, the companies said Tuesday.
You can prove you are over 18 without revealing your birthday. You can prove you have enough money for a transaction without revealing your balance. You can prove a computation was performed correctly without revealing the inputs. Zero-knowledge proofs make all of this possible, and they are quietly becoming the most important cryptographic primitive in
Ethereum can process roughly 15 transactions per second. That is less than a single Starbucks checkout line. Rollups are the technology that lets Ethereum handle thousands of transactions per second without sacrificing the security that makes it valuable in the first place. They work by executing transactions off chain and posting compressed proofs back to
Smart contracts are powerful, but they are also blind. They cannot see prices, read weather data, or verify that a payment arrived in a bank account. Oracles are the infrastructure that connects blockchains to the outside world, and the security of more than $200 billion in DeFi depends on them working correctly. Most explanations of
Without raising the gas limit or shortening block times, $BNB Smart Chain is planning a significant block-building upgrade that could almost double network throughput. One particular inefficiency is addressed by BEP-675: builders and validators currently run the same block twice before it is sealed. Block execution and validation Specialized builders assemble and execute blocks under
A decade ago, most conversations about putting real-world assets on a blockchain in Asia were theoretical, hampered by the absence of clear rules and workable platforms. That era is over. According to a new report from Sygnum Singapore, the shift toward APAC tokenized assets has moved from cautious curiosity to active portfolio building, with the
ADI Chain, a blockchain platform, and Shipfinex, a Dubai-based maritime asset tokenization firm, have announced plans to bring the global ship finance market, estimated at roughly $680 billion, onto blockchain infrastructure. The initiative, first reported by CoinDesk, aims to open up a traditionally closed and relationship-driven financing sector to broader institutional participation. Understanding the Ship
Sui has unveiled Tessera, a business-to-business payments and settlement network designed to keep transaction amounts private, according to an announcement on its official X account. The prototype aims to address a long-standing barrier to blockchain adoption in institutional finance: the public visibility of transaction details. Why privacy matters for institutional settlement Institutions are often reluctant
Dogechain, a separate Ethereum-compatible network from the Dogecoin blockchain, kept producing blocks after its announced 12:00 UTC shutdown on Aug. 8. Its project-run bridge page also remained online, while a Dogechain-specific QuickSwap route continued sending users to Polygon. Dogechain announced the cutoff in July and warned that assets remaining on the chain might become inaccessible
Chain Fusion is the set of protocols that let smart contracts on the Internet Computer ($ICP) read, hold, and sign transactions on Bitcoin and other blockchains directly, without routing funds through a bridge or a wrapped token. Instead of trusting a third-party custodian to lock up Bitcoin and mint a copy somewhere else, $ICP nodes
