The coordinator's page. Paste the unsigned proposal and the signatures the signers sent back; the block is assembled here and shown through the same decoder the signers used. Nothing is sent until you press Transmit.
Transmit
Requests votes from the representatives of the chosen network, then publishes the staple to every one of them individually and reports each answer.
MAINNET. This publishes a block that moves real value. Read the decoded block above once more.
Representatives may demand a fee. The fee is paid by a separate block authored by this account; it is unrelated to the block's signers and the amount is tiny. Leave empty to try without — if a fee is required, transmit fails with a clear message and nothing is published. Never stored, never sent; Wipe clears it.
What this does and does not tell you
Signatures are matched to signers by address and put in the order the block requires. The library rejects a correct set in the wrong order, so this ordering is load-bearing, not cosmetic.
The hash is recomputed from the assembled bytes and must equal the proposal's hash. If attaching signatures changed it, assembly refuses.
The decoded view below the hex comes from the final bytes, not from what you pasted.
Transmit publishes to every representative individually. One acceptance is enough for the network; a representative that already holds the staple may report a failure.
