Hayyānu

Scriptum’s proof-of-work is SHA3-512. It is post-quantum safe — the same stance taken throughout the protocol, where Dilithium3 and Kyber replace classical cryptography. It is also simple. Where memory-hard miners introduce tuning layers, JIT compilation, and sandboxed VM logic, SHA3-512 needs no such machinery. Less complexity is less attack surface.

This choice does mean specialised mining hardware will emerge over time. That is acceptable. The protocol does not fight economic gradients; it expects them and ensures decentralisation through other means.

Hayyānu is the Scriptum miner. It connects to a running Ilmarinen node, registers a reward address, receives mining jobs, hashes against SHA3-512, and submits valid solutions. One binary. One job. Nothing else.

The name Hayyānu is Ugaritic for the Skilled One — the divine craftsman, the smith who forged weapons for the gods. The miner forges the chain’s blocks. The name fits.
