SRA says keep everything. ICO says delete it all. Nexum Ledger satisfies both — immutable audit trails with GDPR-compliant cryptographic erasure, built in Rust.
Solicitors Regulation Authority
“Maintain tamper-evident, immutable records of all client account activity and compliance events. Any gap in the audit trail is a disciplinary matter.”
Information Commissioner's Office
“On request, permanently erase all personal data relating to the data subject. The right to erasure is absolute when the data is no longer necessary.”
Today, most firms manage this with two separate systems and a compliance officer manually reconciling between them. It's expensive, error-prone, and leaves the firm exposed to both regulators simultaneously.
Purpose-built cryptographic infrastructure that makes audit immutability and data erasure structurally compatible.
Every compliance event is SHA-256 hash-chained. Modify any record and every subsequent hash breaks — detectable instantly by any auditor.
Each record is encrypted with a unique key. On erasure request, the key is destroyed — data is gone forever, but the audit chain stays intact.
Merkle roots are anchored to Bitcoin via OpenTimestamps. Any party can verify your audit trail with open-source tools — no dependency on Nexum.
Client account activity, trust transactions, and case events from your practice management system are ingested, encrypted with a unique key, and appended to a hash-chained audit log.
When a client invokes their GDPR Article 17 right, Nexum destroys the encryption key. The data becomes permanently unrecoverable. A destruction certificate is generated as evidence.
Because hashes were computed over encrypted payloads, the chain is unbroken. Your SRA audit passes. Your GDPR obligation is met. Both regulators satisfied, simultaneously.
