‘Multi-Part’ Payments Could Bring Bigger Bitcoin Sums to Lightning Network

Bitcoin tech startup Blockstream said its c-lightning program staff is first to establish a functioning version of “multi-part payments.” 

While the name, c-lightning v0.8.0, is a mouthful, it’s a considerable advancement for the customer experience of the lightning network, a brand new layer that’s possible bitcoin’s biggest shot scaling to promote a far bigger number of duties. The change upgrades the plumbing of lightning network duties so users can send larger lightning duties, with a much smaller prospect of those failing.

 “The user experience of lightning clients is a topic that is brought up often, and we are working actively on improving the status quo, together with the teams working on other lightning implementations. Our goal is to make using lightning as easy as using an on-chain wallet,” quad-core developer Christian Decker explains in a blog post.

Right now, it isn’t quite as easy. For one thing, there’s a possibility there won’t be adequate liquidity in the network to promote the trade, especially for larger obligations. Say a person transmits 0.5 bitcoin through the network. Under the hood, it pops from one node to another until it reaches its destination. Each of those nodes should possess 0.5 bitcoins it might pass into a different node.

If one of these nodes in the road Doesn’t Have enough bitcoin, the customer is outside of luck and the payment fails. )

Multi-component payments manage this dilemma by making it possible to divide a payment into smaller pieces that are easier to send across the network, as a person may combine bitcoin from multiple channels they have available to send duties.

“Multi-part payments allow a lightning node to bundle the capacity in all its channels when making a payment, making larger payments than any individual channel on its own would allow,” Decker writes. “This greatly reduces the headache of managing how many channels to open, and how to allocate funds to them, since you can now simply combine them as and when necessary.” 

Notably, while this release supports sending such payments, it is not feasible to receive them. That performance is still worked.

Decker maintains the code shift additionally “greatly increases” the resiliency of the entire payment network. Since users sending payments aren’t as inclined to should transact employing a massive node, which can be a “single point of failure.”

“The capacity of the largest channel used to be the limiting factor when performing payments. As such, users were incentivised to open a single channel, with as many funds as possible, to a node that was as stable as possible. This led to users rating the reliability of nodes before opening a channel with them, since that node would now be their single point of failure, i.e., if that node was down, they couldn’t do much. With multi-part payments, users can now open multiple channels to multiple nodes, while at the same time being sure that the funds will be there when they need it. For the network, this means more connectivity and better resilience against the threat of big nodes suddenly disappearing.”

Blockstream asserts that the technology will probably be expanded upon in future releases. )
