A fundamental characteristic of Bitcoin’s blockchain architecture is its inherent limitation in scalability. While Bitcoin’s assets and various usage methods may scale, the blockchain itself cannot, due to the requirement for every participant to receive, verify, and relay all transactions occurring on the network. The notion that every individual must fully verify each transaction is ultimately impractical. Bitcoin’s security and integrity rely fundamentally on this collective verification process by all users.
To address these inherent contradictions, solutions have been sought that temporarily secure transactions off-chain, allowing for final settlement on the blockchain at a later, appropriate time. The Lightning Network was developed as the first and most advanced system designed to solve this problem in a decentralized manner. Although the Lightning Network has not evolved exactly as anticipated—falling short of becoming a pure peer-to-peer payments network for users—it has nonetheless established itself as Bitcoin’s first viable second-layer scaling solution. This network may be better suited for businesses and services, although individual users can also benefit from it, and it has emerged as a significant achievement to date.
It is both an honor and a privilege as an editor to work on a subject of such personal importance. Scaling Bitcoin is essential for enabling meaningful and effective progress. I extend my gratitude to all contributors and team members who made this issue possible, especially Aaron Van Wirdum, whose guidance was invaluable throughout the process.
Included in this edition is an exclusive interview, notably with Lightning co-founder Taj Dryja, which delves deeply into the intricacies of Bitcoin’s most powerful scaling layer. This special issue will be available as a limited edition, accessible only while supplies last.
