Real time transactions are coming to Abstract. In this demo, we built a simple cookie clicker where every click is an onchain transaction. You can see each transaction happen immediately with almost no delay. A web2 UX secured by a blockchain under the hood. This is how every app on Abstract will be built in the near future. This particular demo leverages AGW and session keys to remove the need for wallet popups. It uses a special RPC endpoint (which will be live on our mainnet soon) to fetch transaction statuses ahead of time.

Ledger users can now keep their Zcash private in Ledger's own app Ledger added shielded Zcash 🛡️ support to Ledger Wallet Desktop, with every transaction approved on the Ledger device. The private balance covers only $ZEC in Ironwood, the shielded pool that went live in July. Ledger will pull the older Zondax-built Zcash Shielded app from download on Nov. 5, so holders using it need to move their funds before then.

RIPPLE, JP MORGAN, & ONDO TEAM UP TO MAKE HISTORY @OndoFinance, JP Morgan, Mastercard and Ripple joined forces to execute a "landmark pilot transaction connecting the XRP ledger with interbank settlement rails". The pilot transaction leveraged the infrastructure of all three parties to allow Ripple to redeem Ondo Short-Term US Government Treasuries on $XRP Ledger, but outside of traditional banking windows. Though small, the experiment is meaningful, clearly demonstrating blockchain's ability to drive efficiency in the global financial system.

Hey Ledger we need a way to hide near-zero-value transfers, and we need it soon. Address poisoning is flooding the transaction history with dust from lookalike addresses, and it's making the wallet UI almost unusable. A simple "hide dust transfers" toggle would solve this.

Watch the #bitcoin network in action. Each dot on the map represents a computer node, each holding a complete ledger of every transaction. This global network verifies the next block of transactions every ~10 minutes. The system ensures every transaction is recorded on a public ledger, accessible by anyone, yet secure and tamper-proof. As each new block is found, it's transmitted across the network, node by node, in real-time. This decentralized process eliminates the need for a central authority, highlighting Bitcoin's innovative approach to maintaining consensus and security. The nodes, distributed worldwide, are the backbone of Bitcoin's decentralized architecture. Watching them work together to verify transactions and add them to the blockchain provides a clear view of how the system operates efficiently and securely.

StratoVM Development Update - Testnet Upgrade Commencing... Our team has been diligently working behind the scenes to deliver an enhanced testnet version of StratoVM. In response to the increased transaction load and the demands of our rapidly expanding user base, we are preparing to upgrade our testnet infrastructure. This upgrade will introduce a more robust and decentralized node architecture, capable of seamlessly managing higher transaction volumes. Furthermore, the updated testnet will feature enhanced modular capabilities, facilitating the integration of essential DeFi components such as bridges, oracles, and more. This represents a significant milestone for our development team and our partners, who are building on the StratoVM testnet.

Cardano Targets 60X Speed Boost to Rival XRP Ledger Charles Hoskinson says the upcoming Leios upgrade could boost Cardano's throughput by 60 times, putting it on par with the $XRP Ledger. Speaking in an interview with David Gokhshtein He said higher performance could attract more users, increase transaction activity and lift DeFi TVL. The comments come after Hoskinson warned Cardano's ecosystem could suffer if key upgrades fail to gain approval.

⚡️ 100000 $ARTY Were Burned! ⚡️ 🦾 The $ARTY supply just got even smaller – 100000 $ARTY tokens have been burned, reducing the supply by almost 0.5%! This reduction has already increased the value of $ARTY, making it even more exclusive! 🔥 Burn transaction - 📃 If someone wants to burn more $ARTY, you can use a simple instruction: 1. Follow the link - 2. Click on the “Connect wallet” button and connect your wallet. 3. Click on the “burn” function and specify how much of your $ARTY you want to burn. In the “amount" field, you must enter the number of burned $ARTY + 6 zeros. 4. Click on the “Write” button and confirm the transaction. Your $ARTY will be burned.

Canton Network vs. Ethereum: What's the Difference? Ethereum (Ethereum) is a general-purpose public blockchain where transactions and smart contract activity are broadly visible across the network. Validators use proof-of-stake to agree on the chain’s state. Canton Network (Canton Network) takes a different approach, focusing on privacy, interoperability, and institutional financial workflows. Here are the key differences: (1) Privacy Ethereum is transparent by design. Addresses, balances, transactions, contract calls, and events can generally be inspected publicly. Ethereum is now researching additional privacy technologies, including private reads, private transactions, and zero-knowledge proofs. Canton uses sub-transaction-level privacy. Participants only receive the transaction data relevant to them, while sensitive information is shared on a need-to-know basis. (2) Network Structure Ethereum operates as a public blockchain with a shared global state maintained by its network of nodes and validators, plus layer 2 networks that settle back to it. Canton is designed as a network of networks. Applications can operate across different participant nodes and synchronizers while remaining interoperable, connected through the public Global Synchronizer run by super validators. (3) Consensus Ethereum’s proof-of-stake system uses validators to propose and attest to blocks, with validators staking ETH to participate in network security. Canton separates transaction validation from transaction ordering and confirmation. The participants involved in a transaction validate the relevant smart contract state, while synchronizers coordinate ordering and commits. (4) Smart Contracts Ethereum uses the Ethereum Virtual Machine, allowing developers to deploy programmable smart contracts across a broad public ecosystem. Canton uses Daml-based smart contracts and gives applications control over privacy, governance, permissions, and operating policies. This makes Canton particularly suited to workflows where different institutions need to interact without exposing every transaction to the entire network. (5) Main Use Cases Ethereum has developed into a broad platform for DeFi, NFTs, stablecoins, decentralized applications, and other permissionless applications. Canton is focused heavily on financial infrastructure, including tokenized assets, payments, institutional markets, and workflows requiring confidentiality. So, Ethereum emphasizes public verification and permissionless composability, while Canton emphasizes privacy-preserving interoperability between institutions on a public network.
