Vitalik Buterin wants to “make Ethereum cypherpunk again”
Ethereum needs to reignite the cypherpunk revolution first envisioned for the blockchain in its early days, says Vitalik Buterin, one of the network’s founders.
According to a Dec. 28 blog post from Buterin, Ethereum was initially envisioned as a “public decentralized, shared hard drive” that could leverage peer-to-peer messaging and decentralized file storage. However, the vision began to fade in 2017 with the turn toward the financialization of Ethereum.

Transaction Substitution Vulnerability Discovered in Ledger's Ethereum Application

A vulnerability involving transaction substitution has been identified and confirmed in the Ethereum application for Ledger hardware wallets. The issue was a race condition between the transaction data displayed on the device's screen and the buffer holding the actual transaction data. This flaw allowed a malicious actor to overwrite a pending transaction while the user was reviewing a legitimate one on the display, potentially leading to the signing of an unseen transaction. The vulnerability was independently discovered by multiple parties. On August 22, 2026, researcher TestMachine disclosed it after detection by the Azimuth scanning tool. Later, on August 27, OneKey's founder Yishi Wang announced his team had successfully replicated the attack in a lab environment on app version 1.22.1. Ledger's security team, Donjon, responded that no real-world exploits or user losses occurred. They stated the flaw was internally identified and patched in Ethereum app version 1.22.2, released on August 13, 2026—prior to the public disclosures. An update to the underlying Ledger Secure SDK (v26.6.1) followed on August 21. Official security bulletin LSB 023, published August 27, details the vulnerability as residing in the SDK's I/O handling. While there is minor public discrepancy over whether version 1.22.2 or 1.22.3 fully resolved the issue, all parties strongly urge users to update their Ethereum application to the latest version via Ledger Live. The incident highlights a critical security principle: the safety of a hardware wallet depends on the entire chain of components—firmware, SDK, and applications—with a flaw in any link compromising the overall system.
