Privacy has become a major topic in blockchain. While many once believed Bitcoin transactions were anonymous, blockchain tools later showed that most transfers can be traced. Launched in March 2018, it is a privacy-focused DeFi platform that uses Mimblewimble and LelantusMW to hide wallet balances, transaction amounts, and user identities.Unlike many privacy coins that focus solely on payments, Beam is gradually expanding into a private DeFi ecosystem, integrating NFTs, decentralized exchanges, and confidential smart contracts.
