Moving Spaces

Space UTXOs are indistinguishable from standard Bitcoin UTXOs and may carry any value. Spaces can be transferred by following a simple rule. If the space is at input index N, then it will be at output index N + 1.

Listing spaces for sale

You can sell spaces in a trustless way by creating a PSBT with the space as an input and required payment as the output signed with SINGLE|ANYONECANPAY. Then anyone can complete the transaction paying the required amount and getting the Space as one of their outputs.
