we hacked ledger. the OneKey Anzen team has successfully... reproduced a transaction replacement attack against ledger ethereum app 1.22.1 in our lab. the bug is a race condition between the transaction display logic and the underlying transaction buffer. an attacker can overwrite the transaction waiting to be signed while the user is still reviewing a legitimate one. in simple terms: - you see transaction a on your ledger. - you approve transaction a. - your ledger can end up signing transaction b. - and you never see transaction b. to reproduce this, we built the 1.22.1 ELF ourselves, fixed the speculos reset 502 issue, and got the full attack flow working end to end. ledger fixed this in ethereum app 1.22.3. if you’re still on an older version, update it.show more

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.show more

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.show more

XRP’s Centralization Debate Took a Major Hit Asset manager,... 21Shares, has challenged one of the longest-running criticisms surrounding ripple:native and Ripple’s relationship with the XRP Ledger. The asset manager says Ripple operates only one validator among roughly 35 on the default trusted list. XRP Ledger has more than 150 validators in total as per its documentation. For protocol changes, a minimum of 80% of the validators need to agree, which further reduces the control of Ripple. According to 21Shares, Ripple’s dominance does not equate to control over transaction validation.show more
