BlockChained Custody.
Custos records each stage of renewable gas, digestate and carbon credit production as a signed, tamper-evident record. Every blockchain entry proves who supplied each tonne, the standard it meets, and that nobody else has claimed it.
System overview
Signed proof at every stage of production.
Custos is a digital chain of custody platform for renewable gas, digestate fertiliser and carbon credits. It records feedstock intake, anaerobic digestion, pyrolysis, grid injection and land application as cryptographically signed, tamper-evident records. Nine interlocking modules carry that proof from farm to grid, so origin, standard and single-claim ownership can be verified end to end.
Blockchain certification
What each module writes, and what only reads.
Some modules mint new signed records the moment output is produced. Others consume those records without writing new ones. The distinction defines what Custos certifies and what it only reports on.
How Custos uses blockchain certification at each module exit, from feedstock intake through to community reporting
Each of these writes a new cryptographically signed record the moment its output is produced, locked so it cannot be edited after the fact.
These consume already-certified records rather than minting new ones, and the draft system scope doesn't specify chain writes for them.
