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 29113 is at or above the activation height 20000: nodes that enforce M2 accept a block there only with a valid ML-DSA-44 block signature.

The node behind this site enforces M2 and holds this block, so its block signature passed the node's check.

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