# Evidence retention, measured

Measured from the live ledger on every read: 1288 ledger entries in 662 sealed blocks, an average entry payload of 2682 bytes, 3454288 measured payload bytes. The storage meter is live-computed from the ledger on every read. The byte figure is an estimate, derived as ledger entries × the measured average payload size of those entries (SQLite LENGTH(payload) averaged over the live ledger_entries table at the moment of the read); it covers entry payloads only — block headers, signatures, indexes and database overhead are not counted, so it is a payload-size estimate, not a disk-usage figure. Nothing is cached or stored.

Derivation: ledger entries × measured average entry payload size: 1288 entries × 2682 bytes (the live average of LENGTH(payload) over the ledger_entries table) = 3454416 bytes. Payloads only; block headers, signatures, indexes and database overhead are excluded.

## Retention plans

- **Public ledger archive** (ledger_archive) — retains: Public ledger entries; Sealed ledger blocks. Kept: Indefinite — the ledger is append-only by design; entries are the product. Free: verification is free forever and ledger reads and verification are never charged. Founder pricing applies; nothing charged today — no retention price is published, no payment rail is connected, and the first 25 accounts to use each fee-bearing feature hold that feature free permanently under the founder model published at /pricing.
- **Account evidence retention** (account_evidence) — retains: Rights Receipts and signed rights manifests; Activity statements and signed evidence packages. Kept: Life of the account plus the published archive period. Founder pricing applies; nothing charged today — no retention price is published, no payment rail is connected, and the first 25 accounts to use each fee-bearing feature hold that feature free permanently under the founder model published at /pricing.
- **Extended activity retention** (extended_activity) — retains: API activity records. Kept: A limited period by default (180 days in the current configuration); this plan is the waitlist for a longer period. Founder pricing applies; nothing charged today — no retention price is published, no payment rail is connected, and the first 25 accounts to use each fee-bearing feature hold that feature free permanently under the founder model published at /pricing.
