Tools: Blockchains Don’t Have A Privacy Problem. they Have A Memory Problem

This article challenges a core assumption of blockchain design: that transaction history must be stored indefinitely. While debates focus on stronger cryptography and privacy coins, the deeper issue is permanent data retention. Privacy degrades over time as analytical techniques improve and archived transaction structures become more revealing. A non-persistent ledger architecture — where transactions are verified but not permanently stored — could fundamentally reduce long-term risk, reframing privacy as an outcome of minimized historical data rather than stronger encryption alone.
