Ethereum co-founder Vitalik Buterin caused debate this week by criticizing X’s new feature that automatically reveals a user’s country, calling it a dangerous form of forced doxing that puts crypto users at risk.

The Arbitrum team argued that WebAssembly (WASM) is a more flexible, secure, and future-proof choice, and warned that hardwiring RISC-V into Ethereum could lock the network into a rapidly evolving proving technology. Buterin Slams X for Exposing User Locations Ethereum co-founder Vitalik Buterin joined a growing chorus of people in the crypto industry criticizing X’s newly introduced feature that automatically displays a user’s country of origin.
