Bitcoin doesn’t scale.
That shouldn’t be learn to imply that Bitcoin, the asset, or alternative ways to use it don’t scale. However Bitcoin’s blockchain doesn’t scale. It is a elementary and simple actuality of its structure. We’ve identified this definitively because the Blocksize Wars (nicely, Bitcoiners have identified this). Some folks, reminiscent of James A. Donald — an nameless cryptographer who was the primary individual to answer to Satoshi on the cryptography mailing record — and Hal Finney himself, knew this from the very starting.
It isn’t potential for each individual on Earth to need to obtain, confirm and retransmit the transactions of each different individual on the planet. The notion that it is a viable concept is definitely fairly insane.
However that is essentially how Bitcoin works. Its safety and integrity is barely assured via the method of each person receiving and verifying the exercise that’s processed on the blockchain. So how will we reconcile these two contradictory issues?
We discover creative methods to decide to transactions with out utilizing the blockchain, basically “caching” them till an acceptable time to truly interact in closing settlement on-chain.
The Lightning Community is the primary and most mature instance of a system designed to perform this reconciliation in a decentralized style.
Lightning has not precisely developed as we hoped it might — a pure end-user funds community — but it surely has undeniably demonstrated itself as the primary viable second-layer scaling answer for Bitcoin. It’d wind up changing into extra of an mixture settlement layer, or a community extra appropriate for companies and companies than finish customers (although not unattainable for them to make use of), however it’s so far a convincing success.
It has been an absolute pleasure and honor to behave because the Editor-in-Chief for this difficulty, as this matter is one thing very near me personally. Bitcoin is one thing that should scale to be able to create the optimistic and impactful change that I wish to see it create.
I’d wish to thank all of the contributors and group members who’ve made this difficulty occur, and, most significantly, Aaron van Wirdum’s stewardship and assist through the technique of passing the torch to me.
I hope you all get pleasure from gaining a greater understanding of one of the crucial vital initiatives on this area since Bitcoin itself was launched.

Don’t miss your chance to own The Lightning Issue — that includes an unique interview with Lightning co-creator Tadge Dryja. It dives deep into Bitcoin’s strongest scaling layer. Restricted run. Solely accessible whereas provides final.
This piece is the Letter from the Editor featured within the newest Print version of Bitcoin Journal, The Lightning Situation. We’re sharing it right here as an early have a look at the concepts explored all through the complete difficulty.
