ML-DSA-44 block signature (M2)

M2 is an experimental rule of this test network. From a height set in its build, a node that enforces M2 accepts a block only if, besides the classical signet signature, the block carries a valid ML-DSA-44 signature by the Ark-0 block key, in its coinbase's witness commitment output. This page shows that signature; it does not check it.

Block 19963 is below the activation height 20000: nodes do not require this signature, and only log the result of checking it when run with -debug=validation. The block producer adds it from height 18000 on, so that nodes can check it before it is required.

Status

In the form M2 requires, followed by the signet solution push (the classical signature)
