The best way to scale Bitcoin has been a hot topic since its inception. Whether it be through Bitcoin-backed banks as Hal Finney suggested back in 2010, increasing the throughput on the Bitcoin blockchain, layer 2 solutions like the Lightning Network, or federated custodian options like Fedimints.

Over the past year, the surge in Bitcoin transaction fees, largely attributed to the emergence of BRC20 tokens, ordinals, and inscriptions, has once again brought the topic of scaling Bitcoin to the forefront of conversation. High fees have priced smaller transactions out of the market, and the Lightning Network, hailed as a potential solution to scalability challenges, has faced some initial hurdles.

The different scaling solutions all have different trade-offs. Trustlessness and trust minimization are key tenets of Bitcoin, ensuring that users do not need to trust any central authority or third party. The Lightning Network aligns with these principles as it enables trustless, peer-to-peer transactions, reducing the need for custodial services and enhancing individual control over funds.

While Bitcoin's primary focus is on decentralization and self-sovereignty, some developments, such as the concept of the "Wallet of Satoshi" or Bitcoin ETFs, aim to make Bitcoin more accessible and user-friendly to a broader audience. Wallet of Satoshi is a custodial Lightning wallet designed to simplify the user experience, while Bitcoin ETFs provide a means for traditional investors to gain exposure to Bitcoin without directly holding the asset. These developments have the potential to expand Bitcoin's adoption, but may raise concerns about centralization and counterparty risk.
