Spark — Lightspark’s Bitcoin Layer 2
Spark is a Layer 2 protocol for Bitcoin that leverages statechain know-how. In brief, customers can maintain fractions of bitcoin off-chain, and switch these by sending personal keys to different customers (relatively than signing transactions with the keys).
Lightspark created Spark to raised help the onboarding of customers to the Lightning Community, which usually requires an on-chain transaction for every cost channel in addition to the locking up of some quantity of bitcoin in these channels so customers can ship and obtain transactions.
The layer 2 was primarily borne from the frustration that the Lightspark staff encountered in making an attempt to create a non-custodial Lightning pockets for customers.
“Self-custodial Lightning wallets, particularly at scale, simply aren’t viable,” Lightspark CTO Kevin Hurley informed Bitcoin Journal.
“If you’re opening channels for billions of customers, charges are going to undergo the roof, and you are going to refill block house. It is simply one thing that is not going to be affordable and also you lock up liquidity for each single person,” he added.
Hurley additionally shared that Lightspark didn’t need to watch for the enabling of Bitcoin opcodes (like CheckTemplateVerify or TapleafUpdateVerify) that may make it cheaper to open new Lightning channels. Lightspark needed to supply customers a non-custodial possibility instantly.
So, they constructed Spark, a Bitcoin Layer 2 that provides customers low-cost, on the spot funds in addition to a permissionless, unilateral exit to the Bitcoin base layer. It additionally allows offline obtain, or the power to obtain bitcoin even when your gadget isn’t related to the web.
Moreover statechains, Spark additionally makes use of atomic swap know-how. Its design is much like that of Mercury Layer in that it allows the off-chain switch of possession of Bitcoin UTXOs whereas benefiting from close to on the spot and fee-free transactions, based on Hurley.
“Mercury has numerous core limitations that we transcend,” defined Hurley.
“In Mercury, for instance, you’ll be able to switch complete UTXOs solely. You’ve absolute time bombs the place it’s a must to return on chain at some absolute time. So, you’ll be able to solely accomplish that many transactions. Additionally, we pull in numerous items like connector transactions from Ark, for instance, however, aside from that, we’re not much like Ark in any respect,” he defined.
“I believe it is arduous to check it to one thing, as a result of it pulls in numerous totally different elements, and I believe the trade-offs that we selected to make are totally different than many others in all probability selected to make.”
Moreover bitcoin, it’s additionally doable to situation and use stablecoins on Spark. Or you’ll be able to situation stablecoins through Taproot belongings, LRC-20 or RGB on the bottom layer and switch them to Spark.
A novel dimension of Spark, although, is that the belongings on the layer 2 are all UMA enabled.
“Now you can have non-custodial customers sending on to the financial institution accounts of UMA Prolong customers,” stated Hurley, mentioning one of many new functionalities of UMA addresses.
UMA Prolong
UMA Prolong integrates the Lightning Community with conventional banking methods, permitting customers to make worldwide financial institution transfers in seconds.
