BTC Privacy on L2: Fully Self-Custodial Bitcoin L2s With VMs Can Enable Stealth Addresses, Says @muneeb — What Traders Should Watch

According to @muneeb, Bitcoin will likely never add privacy at the base layer, placing future privacy features on BTC L2s instead. source: @muneeb He states that if BTC on L2 is fully self-custodial and the L2 offers a full VM, stealth BTC addresses can be implemented at the L2 level. source: @muneeb He adds that information leakage occurs when bridging, but moving from a public L1 address to a stealth L2 address also leaks data, with the design keeping the public address on L1 and the stealth address on L2. source: @muneeb He identifies the core technical hurdle as guaranteeing fully self-custodial L2 BTC so users can always reclaim BTC even if the L2 fails. source: @muneeb He concludes that once fully self-custodial, programmable BTC on L2 exists, a new privacy design space opens, positioning BTC privacy as an L2-driven narrative for traders to track. source: @muneeb
