Reminder that WalletConnect can easily track and link all the dapps you visit and who you are WalletConnect relays can know that some wallet with some website domain used by some device with some IP address, is connected to some dapp with some website domain used by some device with some IP address Let's say you connect from MetaMask on your iPhone at home, to Uniswap on your computer at home but under VPN WalletConnect will know for sure that: - wallet is MetaMask (got from MetaMask's project ID) - wallet used this IP address and thus some relatively precise location - wallet is on a phone (if we suppose lack of HTTP headers with means it's a native app which means it's probably on a phone) - dapp is Uniswap (got from HTTP origin header or by Uniswap's project ID) - dapp used this IP address which is a VPN and thus can link your home address to your VPN address as both are connected together - dapp used these language settings (got from HTTP language header) - dapp used Chrome/Firefox/whatever (got from HTTP user-agent headers) So they know all the dapps you used with MetaMask on your phone, as well as your IP addresses and other funny metadata Even worse, WalletConnect has a cookie-like thing named "client_id" that can track you even if you change your IP address, so they can know all the previous IP addresses of some user So if you use VPNs thinking it would break the link, it actually reinforces it by linking your VPN address to whatever previous IP adresses you used, unless you actually clear all caches But now I will release some tools to fix it all so like and subscribe ☀️

Litecoin took a 13-block reorg. On-chain timestamps show blocks 3095930-3095943 took ~3h to mine, normally a 30-minute window. Block time during the attack: 13.5 min average, 5.4x slower than baseline. That's the signature of a 51% attack: public chain mines slowly while the attacker builds a private chain in parallel. Once the private chain becomes longer, it replaces the public one. 13-block reorg is the outcome. Anyone running cross-chain LTC infrastructure needs to extend confirmation requirements or pause inflows. Low-hashrate L1s aren't safe collateral for cross-chain value anymore.
