+excerpt: >
+  **Ark** is a trustless joinpool-style protocol where a large number
+  of users share a UTXO by accepting a counterparty as a co-signer on
+  all transactions within a certain time period.  This spreads the cost
+  of onchain fees from using that UTXO across many users, minimizing
+  their individual costs.
+
+---
+The users can either unilaterally withdraw their bitcoins onchain
+after the expiry of the time period or instantly and trustlessly
+transfer them offchain to the counterparty before the end of the time
+period.  Normally, a user will simply roll their bitcoins into another
+contract with the counterparty, which can be highly fee efficient when
+done with many other users at the same time.  Alternatively, the
+counterparty may help the user make a payment onchain, through LN, or
+through any other protocol supported by the counterparty.  Presumably,
+the counterparty would pass along to the user any fees the
+counterparty had to pay for using the payment protocol, e.g.
+forwarding fees if LN was used.
+
+Ark can be implemented on Bitcoin with no consensus changes required,
+but it will support a larger number of users---making it much more fee
+efficient---if a [covenant][topic covenants] feature is added to
+Bitcoin.
