The channel can be between -the sender and recipient or a target of recipient's choice. Using an CHECKTEMPLATEVERIFY, the -recipient may give the sender an address which makes a tree of channels unbeknownst to them. -These channels are time insensitive for setup, as all punishments are relative timelocked to the -penultimate transaction node. -Thus, coins sent using a congestion controlled transaction can still enjoy instant liquidity. - -====Non-Interactive Channels==== - -When opening a traditional payment channel, both parties to the channel must participate. This is -because the channel uses pre-signed multi-sig transactions to ensure that a channel can always be -exited by either party, before entering. -With CHECKTEMPLATEVERIFY, it’s possible for a single party to construct a channel which either -party can exit from without requiring signatures from both parties. -These payment channels can operate in one direction, paying to the channel "listener" without need -for their private key to be online. -<img src="bip-0119/nic.svg" align="middle"></img> - -====Increased Channel Routes==== - -In the Lightning Network protocol, Hashed Time Locked Contracts (HTLCS) are used in the construction -of channels. A new HTLC is required per route that the channel is serving in. -In BOLT #2, this maximum number of HTLCs in a channel is hard limited to 483 as the maximum safe -size to prevent the transaction from being too large to be valid. In common software implementations -such as LND, this limit is set much lower to 12 HTLCS. This is because accepting a larger number of -HTLCS makes it more difficult for transactions to confirm during congested periods as they must pay -higher fees. -Therefore, similarly to how congestion control is handled for normal transaction, lightning channel -updates can be done across an CHECKTEMPLATEVERIFY tree, allowing nodes to safely use many more -HTLCS. -Because each HTLC can have its own relative time lock in the tree, this also improves the latency -sensitivity of the lightning protocol on contested channel close. - -===Wallet Vaults=== - -This section will detail two variants of wallet vault that can be built using -CTV. Wallet vaults are a useful tool when greater security is required for -cold storage solutions, providing default transactional paths that move funds -from one's cold storage to a hot wallet. - -One type of cold wallet can be set up such that a customer support desk can, -without further authorization, move a portion of the funds (using multiple -pre-set amounts) into a lukewarm wallet operated by an isolated support desk. -The support desk can then issue some funds to a hot wallet, and send the -remainder back to cold storage with a similar withdrawal mechanism in place. -This is all possible without CHECKTEMPLATEVERIFY, but CHECKTEMPLATEVERIFY -eliminates the need for coordination and online signers, as well as reducing -the ability for a support desk to improperly move funds. Furthermore, all such -designs can be combined with relative time locks to give time for compliance -and risk desks to intervene. This is a 'Coins at Rest' or 'Optically Isolated' -vault, and is shown below. - -<img src="bip-0119/vaults.svg" align="middle"></img> - -An alternative design for vaults is also highly effective and simpler to -implement in Sapio, a smart contract programming language. In this design, the -user commits to a single UTXO that contains a program for an annuity of -withdrawals from cold storage to a hot wallet. At any time, the remaining -balance for the annuity can be cancelled and funds locked entirely in cold -storage. The withdrawals to the hot wallet can be 'cancelled' before a maturity -date to ensure the action was authorized. These sort of vaults strongly benefit -from non-interactivity because the withdrawal program can be set up with cold -keys that are permanently offline, except in case of emergency. The image below -shows an instance of this type of wallet vault created with Sapio in Sapio -Studio.
