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 basic and plain actuality of its structure. We’ve identified this definitively because the Blocksize Wars (nicely, Bitcoiners have identified this). Some individuals, equivalent to James A. Donald — an nameless cryptographer who was the primary particular person to answer to Satoshi on the cryptography mailing record — and Hal Finney himself, knew this from the very starting.
It isn’t doable for each particular person on Earth to should obtain, confirm and retransmit the transactions of each different particular person on the planet. The notion that it is a viable concept is definitely fairly insane.
However that is basically how Bitcoin works. Its safety and integrity is barely assured by way of the method of each consumer receiving and verifying the exercise that’s processed on the blockchain. So how can we reconcile these two contradictory issues?
We discover ingenious methods to decide to transactions with out utilizing the blockchain, basically “caching” them till an applicable time to truly have interaction 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 will — a pure end-user funds community — however it has undeniably demonstrated itself as the primary viable second-layer scaling resolution for Bitcoin. It would wind up turning into extra of an combination 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 problem, as this matter is one thing very near me personally. Bitcoin is one thing that should scale to be able to create the constructive and impactful change that I wish to see it create.
I’d wish to thank all of the contributors and staff members who’ve made this problem occur, and, most significantly, Aaron van Wirdum’s stewardship and assist throughout the means of passing the torch to me.
I hope you all take pleasure in gaining a greater understanding of one of the crucial essential tasks on this house 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 Difficulty. We’re sharing it right here as an early take a look at the concepts explored all through the total problem.
