Byte-for-byte comes first
A hash is only comparable when both parties agree on the exact bytes: encoding, line endings, whitespace and whether metadata is included. Keep the original payload and the provider's canonicalisation rule. A screenshot of a transaction is not enough; an independent reader should be able to recompute the same digest.
Prove sequence, then test the trade
A public timestamp can support the claim that a commitment existed before a later market outcome. It does not prove the trading instruction was complete, delivered to subscribers on time, filled at the advertised price or profitable after fees. Check the original entry, stop, exit rule, exchange venue and revision history separately.
Crypto-specific execution checks
Use the exchange and pair that a subscriber could actually access. Account for maker or taker fees, spread, funding on perpetuals, liquidity, exchange outages and delisted assets. A token's candle high is not evidence that subscribers could sell there. An honest archive includes calls that never triggered as well as calls that failed.
