DemoFor public education only. These blocks are built by PisoScan from published PhilGEPS records to show how a budget ledger like CADENA would work. No government agency created or signed them, and this is not an official ledger. How it works
How a public budget blockchain would work
Every PhilGEPS construction award is fingerprinted, grouped into one block per award day, and chained to the block before it. Change one peso in any record and every block after it stops matching. Try it on any transaction page, for example this DPWH contract, which also shows its budget-to-payment trail.

1. Fingerprint every record
Each award is turned into a SHA-256 hash. Change any field and the hash changes completely.
2. Chain the blocks
Each day's records form a block. The block stores the hash of the block before it, so the blocks form one unbroken chain.
3. Anyone can check
Re-hash the records and compare. One edited record breaks its block and every block after it.
