The Lightning Network is a second layer constructed on prime of the Bitcoin Network that enables for transactions to occur extra rapidly and effectively with out the necessity to wait on blocks being confirmed on-chain.
To circumvent the necessity to look forward to on-chain confirmations for every transaction, node operators open fee channels to different nodes with a selected quantity of bitcoin going into the channel. This preliminary transaction is confirmed on chain, however as soon as a channel is opened, funds can transfer seamlessly by means of fee channels throughout nodes all through the community.
But one of many challenges with Lightning Network is the difficulty of liquidity. Lightning funds can solely journey throughout nodes which have adequate funds on each the inbound and outbound aspect of the channel.
To discover this basic problem to Bitcoin’s most widely-used second layer protocol, a bunch of specialists gathered at Bitcoin 2022 for a panel dialogue titled “Lighting Service Providers And Liquidity.” The group included: Michael Tidwell, who is head of system operations at Zebedee and organizer of The Atlanta Bitcoin Conference; Lisa Neigut, a Core Lightning developer (previously c-lightning) at Blockstream; Roy Sheinfeld, the co-founder and CEO of Breez; João Almeida, the co-founder and CTO of OpenNode; and Ryan Gentry, the director of enterprise improvement at Lightning Labs.
Sheinfeld, who coined the time period “Lightning service providers (LSP),” mentioned, “LSPs are similar to IP addresses because they facilitate connectivity to the Lightning Network,” related to how IP addresses permit folks to join to the web. He continued, “The LSP is the bridge between the network and the Lightning node.”
Gentry defined, “There’s the core of the network which is the big nodes that are doing the routing and the edge of the network which are the users.” The LSP helps join the sides of the community to the core. Almeida mentioned, “Eventually the goal is for the business to be self-serving. Every business should run their own [Lightning] infrastructure.”
Neigut helped clarify what liquidity means for the Lightning Network.
“When we’re talking about liquidity, we’re talking about bitcoin that’s being committed to Lightning channels,” she mentioned.
LSPs assist to fill within the hole for the sides of the community by serving to customers get inbound liquidity so as to obtain funds.
Neigut mentioned, “LSPs are the service that provide the ability to receive and send payments over Lightning, but receiving is the main challenge.”
Inbound liquidity is one of many greatest challenges for onboarding new folks.
Kraken not too long ago included Lightning and it rapidly grew to become one of many top-ten nodes with bitcoin capability. This is not as easy for the typical person. Sheinfeld mentioned, “I will say there are two different issues: onboarding new users and connecting to other nodes in the network.”
LSPs are attempting to resolve each of those challenges by pushing liquidity to the brand new customers and in addition leasing liquidity.
Liquidity advertisements is a proposal that Neigut wrote for the Lightning spec that may hopefully be built-in with all various kinds of Lightning implementations. This is a means you promote that you’ve got capital and may set a fee for a way a lot you need to be paid.
Pool is Lightning Labs’ liquidity answer, the place bitcoin is leased to a person for a fee channel and funds are locked right into a channel that may’t be closed till the lease time period is up. Sheinfeld shared among the causes behind LSPs. “There is a misconception that Lightning is free. In order for Lightning to be successful, routing fees need to go higher.”
Almeida mentioned the problem of custodying bitcoin, the authorized challenges of working a enterprise and the problems with being a custodial LSP.
“I would say the biggest challenge is the user onboarding today. Obviously, custodial service makes it easier. Is it the best solution? I don’t think it is.”
Lightning Labs has one other service known as Loop which is a bridge between on-chain and Lightning bitcoin the place customers can ship or obtain funds on Lightning and Lightning Labs will change the funds for on-chain funds and vice versa.
Tidwell requested, “Does BOLT12 or Taproot affect LSPs?”
Gentry responded, “Taproot from a basic stage opens up lots of what might be accomplished on Lightning. Taproot permits far more use circumstances on Lightning,” Almeida expanded, “Taproot will bring more privacy to Lightning.”
Neigut pushed back against this idea, saying, “I don’t think Taproot is going to solve the privacy problem. I think blinded routes with BOLT12 will be a better solution.”
Gentry shared that BOLT12 was not a priority for Lightning Labs this quarter. Sheinfeld believes that both will be important for privacy on Lightning.
