The "100 ETH" pool on Tornado Cash experienced a significant 40% drop in its Total Value Locked (TVL) over the past week, with 120,600 ETH being transferred, according to crypto analyst Cryptosolv. Onchain Lens identified the address involved as belonging to crypto developer Richard Heart, potentially linked to his new project, ProveX. Over the last four months, Heart has moved a total of 162,937 ETH through Tornado Cash. ProveX is reportedly designed to facilitate fully trustless, peer-to-peer cryptocurrency transactions and settlements using zero-knowledge proof technology. This development highlights the ongoing shifts in the crypto landscape as developers explore advanced privacy and transaction solutions.
