The Ledger — Immutable Replacement and Historical Reads

How new source-pinned testnet posts work, how legacy messages were recorded, and the limits of testnet/RPC data availability.

5 min readTutorial

Storing data in transaction calldata

EVM transactions include input data containing ABI-encoded function arguments. A successful legacy `post(message)` call placed message bytes in that transaction input and emitted a `MessagePosted` event. The contract has no function to edit a confirmed transaction. Availability still depends on the LiteForge testnet and an RPC, archive, or explorer retaining the relevant history. The Lester website is a paginated event/RPC view, not a complete archive or a perpetual-storage guarantee. The legacy owner could change the fee and treasury route, so the system was not admin-free.

A confirmed transaction cannot be edited through the Ledger contract, but testnet continuity and historical RPC availability are not guaranteed. Paid posting to the legacy Ledger is disabled.

Reading and verifying a historical message

1

Go to The Ledger

Navigate independently to lester-labs.com/ledger. A wallet is not required to read the sampled feed.

2

Locate the exact transaction

Use the displayed hash to retrieve the exact transaction, status, block, sender, target, input data, and event log through an independently selected RPC or explorer.

3

Authenticate the posting target

Never call the legacy Ledger or send it zkLTC. A new post must target the immutable replacement on chain 4441 and show its exact runtime, message, 0.01 zkLTC minimum value, and fixed test-treasury behavior before signing.

4

Interpret the record narrowly

The sender address proves only which key authorized the transaction. It does not prove a real-world identity, message accuracy, project endorsement, or perpetual availability.

Reading The Ledger without a wallet

The Lester feed requests historical events through LitVM RPC and presents a bounded, paginated view. When exact completeness matters, query a separately selected archival data source and preserve the transaction hash and receipt. No single public RPC or website is assumed to retain every historical record indefinitely.
