Scaling Lightning? How Revive Could Boost Bitcoin’s Boldest Scaling Plan

Computer researchers from the Swiss university ETH Zürich have uncovered a way to make off-blockchain payment networks even much more scalable.

At the heart of this function lies bitcoin’s years-previous scaling discussion, which will come down to the fact that bitcoin and all cryptocurrencies today have confined transaction potential. To get all around this, cryptocurrency protocols have made payment channel networks that force transactions off-blockchain, these types of as bitcoin’s Lightning Network, initial proposed in 2015.

But researchers Rami Khalil and Arthur Gervais believe that payment devices like the Lightning Network never go much sufficient, and they have proposed the Revive payment channel design, an plan that would empower extended-lasting payment channels that interact even significantly less with the blockchain.

The paper explains:

“Apart from in the situation of disputes (equivalent to typical payment channels), our remedy does not need on-chain transactions and as a result boosts the scalability of present blockchains.”

At its main, Revive enables buyers to securely shift cash from 1 channel to one more off-blockchain, a departure from the Lightning Network’s design.

Rebalancing act

As proposed, all Lightning-type networks require to use on-blockchain transactions (and the accompanying costs) to established up and close payment channels.

End users with various payment channels open – for example, 1 could continue to be open with a coffee store, while one more could pay back for streaming Tv set – typically have to “rebalance” the channel via on-chain transactions just about every time a channel operates out of bitcoin.

Revive, on the other hand, enables cash from the coffee channel to be despatched to the Tv set streaming channel if its funds turn out to be depleted.

“As these types of, alternatively of refunding a channel (which incurs high priced on-chain transactions), a consumer should be able to leverage his present channels to rebalance a improperly funded channel,” the paper explains.

It may well feel like a modest improve, but just about every optimization could matter, in particular at a time when on-chain transaction costs are raising (and could maximize even much more if the cryptocurrencies turn out to be much more common).

The scientists go on to reveal that Revive can be employed for any Lightning Network-like undertaking on any blockchain, which includes Raiden Network, an in-progress payment channel design for ethereum, wherever the researchers have unveiled a Revive proof-of-notion.
