Commentary is resurfacing on the 'blockchain trilemma' β the difficulty of achieving scalability, security and decentralisation at once β which has kept blockchain from mainstream adoption. Writers point to persistent lack of transaction privacy and fragmented interoperability between networks, causing congestion, high fees and exposure of sensitive financial data. Zero-knowledge proofs are being floated as the technology that could overcome these limits.

Researchers have introduced a proposal called 'Shielded Bitcoin' aimed at bringing transaction privacy to Bitcoin without requiring a network-wide soft fork. Misha Komarov, co-founder of alloc/init, explains that the design uses zero-knowledge proofs and Bitcoin PIPEs to hide on-chain transactions. The proposal is drawing attention in crypto circles, where privacy upgrades to Bitcoin have long been debated given the trade-offs between confidentiality and network consensus rules.

Signal has enabled registration without a phone number in Android Beta 8.28.1, with iOS support planned later. The optional feature is a one-time purchase costing $2.99 or β¬3.49, with payments processed using zero-knowledge proofs so transactions cannot be linked to accounts. Privacy-focused users welcomed the move as a step away from phone-number identity requirements, though the paid model has drawn some debate.
