Logical Erasure, Key Destruction & GDPR Alignment

Meet GDPR and privacy reviews without pretending the chain rewrote itself. Evercore destroys operational keys, revokes access, and issues attestations while retention and legal hold stay in the same policy lane as the rest of the trust layer.

Address the GDPR objection without pretending the chain rewrote history.

Arweave transactions remain immutable. Evercore’s erasure posture focuses on what regulators actually need in practice: destroying operational decryption material, revoking access paths, and recording an auditable attestation that ciphertext is practically irrecoverable through the product — alongside retention and legal-hold policies you already define.

Value

Logical erasure with cryptographic intent

Key destruction and access revocation mean the service no longer has a supported path to recover plaintext, even though the ciphertext blob remains addressable on-chain.

Works with retention and legal hold

Policy evaluation still runs before destructive actions so holds and WORM classes are respected in the same governance lane as exports and rooms.

Evidence-friendly narrative

Legal and DPO reviews get a documented flow (what was destroyed, what proof was emitted) instead of hand-waving about “delete from blockchain.”

How it works

Immutability stays true

Arweave does not rewrite blocks. Marketing and legal copy must say so plainly — then layer what you can control.

Governance gate

Retention classes and legal holds evaluate before destructive work. Same policy engine as exports and rooms.

Key destruction + revocation

Operational decryption material is destroyed; API access and sharing paths are revoked so the product cannot recover plaintext.

Attestation & audit trail

Certificates and audit logs document what ran, when, and under which approval — for DPIAs, regulators, and customer security reviews.

For operators

• Wire erasure requests into your data-subject workflow after classification — not as a silent background sweeper.
• Keep export packs and trace IDs aligned so post-erasure audits can still prove what was disclosed before destruction.
• Treat permanence as a feature for integrity; treat erasure as a feature for eligibility — document both in customer DPIAs.

For buyers

• Removes the single largest emotional blocker to selling permanent storage into EU-heavy accounts.
• Gives compliance teams language that matches how cryptography actually behaves.
• Complements SOC2 / HIPAA monitoring narratives: controls, logs, and attestation — not magic deletion.

Does Evercore delete data from Arweave?

No vendor can erase historical blocks from Arweave. Evercore implements logical erasure: destroy keys and access paths, document the event, and align with retention and legal-hold policy so operations match GDPR expectations for practical unavailability.

How is this different from "delete" in S3?

Mutable object stores can remove bytes from their control plane. Here, ciphertext may remain addressable on-chain while your governance story is about irrecoverability through Evercore and provable process — not about rewriting the permaweb.

Who approves an erasure request?

Configure approvals to match your organisation: DPO, security, or automated policy when risk is low. The API supports multi-step approval before execute.
