Ripple Lays Out Four-Stage Plan for XRPL Quantum Defense
Ripple has outlined a four-stage security roadmap to prepare the XRP Ledger for post-quantum cryptography, partnering with Project Eleven to ensure full network readiness by 2028.
Proof-of-activity
Proof-of-activity (PoA) is a hybrid blockchain consensus mechanism that combines elements of proof-of-work and proof-of-stake. Initially, miners use proof-of-work to generate a block template, after which selected stakeholders validate the block through proof of stake. This approach reduces energy consumption compared to traditional proof-of-work while maintaining network security and decentralization. It incentivizes both miners and stakeholders to participate honestly in block creation. PoA provides a balanced consensus model that enhances efficiency and security.
