By using OP_CHECKTEMPLATEVERIFY, a large volume payment processor may aggregate all their payments into a single O(1) transaction for purposes of confirmation. Then, some time later, the payments can be expanded out of that UTXO when the demand for blockspace is decreased. |

Various approaches to alleviate this have been proposed, most prominent of which are payment and state channels, sidechains, commit-chains, rollups, and sharding. This work puts forth a novel commit-chain protocol, Bitcoin Clique. It is the first trustless commit-chain that is compatible with all major blockchains, including (an upcoming version of) Bitcoin. |

It details the current state of DLC protocols, the computational complexities involved, and how CTV can optimize these processes. By using CTV and Taproot, DLCs can reduce computational costs and data exchanges, simplify threshold oracle setups, and eliminate certain multiplications. These improvements make DLC transactions faster and more efficient, even on resource-constrained devices, though with some trade-offs in witness size and transaction distinguishability.</description></item><item><title>Decentralized options</title><link>https://utxos.org/uses/options/</link><pubDate>Sun, 11 Oct 2020 10:45:58 -0700</pubDate><guid>https://utxos.org/uses/options/</guid><description>Trading of bitcoin derivatives is a huge market nowadays.

6 | 6 | Main protocol Option creation will follow this protocol: |
7 | 7 | Use an atomic swap to sync these two operations: User pays fee to underwriter Underwriter sends tokenized USD [1] to an address that is encumbered by the script: After X+K blocks: Send to underwriter After X blocks: If spending tx sends Y BTC to underwriter, send to user When the option reaches maturity the user can exercise it by sending a transaction that: Sends BTC to underwriter Spends the UTXO created on step 1 and sends it to the user&rsquo;s wallet If the user doesn&rsquo;t exercise it on time the underwriter can just spend it to itself Reduction of capital requirement As it is, this protocol requires locking 100% of the collateral for as long as the option stays in effect, but it would also be possible to reduce the capital requirement quite substantially by changing the protocol to make the underwriter lock only 30-50% initially and, at option expiration, make it provide the rest of the payment in case the user decides to exercise the option.</description></item><item><title>Drivechains</title><link>https://utxos.org/uses/drivechains/</link><pubDate>Sun, 11 Oct 2020 10:45:58 -0700</pubDate><guid>https://utxos.org/uses/drivechains/</guid><description>Partial Retraction &ndash; Please See Below Drivechain&rsquo;s peg-out mechanism could be implemented at the transaction level through scripts that force the funds being withdrawn from the sidechain to go through a chain of N transactions, each one of these being in a different block. More specifically, this would be implemented by creating N scripts that would contain an integer constant and would only be spendable to another copy of the same script with the constant increased or decreased by one, with the exception of the script where the constant reaches the value N, in which case the UTXO would be spendable only to a specific address provided in the beginning of the process.</description></item><item><title>Resources</title><link>https://utxos.org/resources/</link><pubDate>Thu, 28 May 2020 17:48:34 -0700</pubDate><guid>https://utxos.org/resources/</guid><description>This page serves as a general index of resources. |
