TREE NEWS update: BIT (formerly Matrixport) published version 2.0 of its Trust Whitepaper, outlining a layered security model in which identity, permissions, operations and asset custody are separated. The disclosure follows a September breach on the Bitcoin sidechain Liquid Network in which an attacker exploited a validation flaw in Elements software to move roughly 4,000 BTC, worth about $320 million at the time, even though PAK and Federation keys were not compromised.
BIT Trust Whitepaper V2.0 Details Multi-Layer Security After $320M Liquid Network Breach
The timing is the message: BIT is publishing a trust architecture weeks after a breach that bypassed key-based security entirely, suggesting the industry's custody debate is shifting from key management toward validation and software integrity. The separation of identity, permissions, operations and custody is a governance answer to a technical failure, and it matters most for institutional counterparties assessing trust infrastructure. Whether such layered models become standard across custodians, or remain a differentiator for early movers, is the open question.
