Raising the Bar for Bitcoin Application Performance with the Blockstream Explorer API

Bitcoin adoption is climbing. Developer mindshare is returning to Bitcoin as the dominant chain for building serious applications. Wallets are gett...

112 years ago today, the Federal Reserve Act was passed. A plan drafted in secret by seven bankers on Jekyll Island controlling 1/4 of the world's wealth. It's how central banks took control of the money and why Bitcoin in self-custody with Jade offers an exit.

This code implements RSA encryption—the foundation of secure communication. In the 90s governments classified it as a weapon & tried to ban its export. Bitcoin uses digital signatures, applying these same public-key cryptographic principles to secure the network. Math won. Wear the math they couldn't ban. Support the principles that Bitcoin is built on. Limited edition RSA t-shirt available now. https://store.blockstream.com/products/rsa-t-shirt-2025-limited-edition

New from Blockstream Research: Cryptography Lead Jonas Nick and Mikhail Kudinov analyze post-quantum signature schemes optimized for Bitcoin. Signature sizes reduced to ~3-4KB, practical for on-chain use, while building on hash functions Bitcoin already trusts. Full Paper: https://eprint.iacr.org/2025/2203.pdf

@npub1qg8j...24kw joined Yahoo Finance’s Market Catalysts this morning to break down: 🔹 Why Bitcoin’s 2025 price action looks “lackluster” on the surface 🔹 Why Bitcoin treasury companies are becoming a compelling investment theme 🔹 How today’s landscape compares to when he first got involved in 2013 A great overview of where Bitcoin stands heading into 2026.

In the 1990s, governments tried to ban strong encryption. Cypherpunks printed RSA code on t-shirts to prove a point: you can't stop math. Three decades later, Bitcoin proves they were right: you can't stop math. You can't ban freedom. When @npub1qg8j...24kw printed the original RSA code t-shirt in 1995, he showed that mathematical truth can't be banned. Today's limited edition version carries that spirit forward. Wear the code that challenged authority just by existing. https://store.blockstream.com/products/rsa-t-shirt-2025-limited-edition
