| # MANTRA |
|
|
| **A deterministic, auditable programming language for ledger operations, cryptographic sealing, and verified integer computation.** |
|
|
| Zero external dependencies. Pure Python. Auditable SHA-256. MUMPS gateway. |

|
| ## What It Is |
|
|
| MANTRA is a purpose-built language for sovereign ledger operations. Every computation is deterministic and traceable. Every output can be cryptographically sealed. No external dependencies — the SHA-256 implementation is pure Python and auditable line by line. |
|
|
| ``` |
| # Constants and variables |
| const GENESIS = "0000000000000000000000000000000000000000000000000000000000000000" |
| let amount = 450000 |
| |
| # Annotated deterministic function |
| @deterministic |
| define seal(tx) |
| let h = sha256(tx) |
| Result::ok(h) |
| end |
| |
| # Run |
| python mantra.py run examples/ledger.m |
| python mantra.py hash "hello world" |
| ``` |
