This year globally, reachable Bitcoin nodes grew ~19.3% in total number. Each node is a computer running Bitcoin software that records the full blockchain, independently verifies every transaction, and relays data to peers, making Bitcoin more secure.

We support both Native Segwit and Taproot addresses, each with its own balance. When you enable Bitcoin in Phantom, Native Segwit is the default BTC address. Here’s how to turn on Taproot 👇

Each dot on this animated #bitcoin network map represents a node and connection to one of the estimated ~50,000 computers with a full record of all transactions. Nodes use this information to audit, validate, and secure the globally decentralized system:

I used Opus 5.5 to build & port 3 procedural buildings from Blender geometry nodes to the web. The node graphs run live in three.js, a procedural city wraps around them, with light & camera presets. Live demo, source-code & .blend files included:

Core Lightning developers are telling node operators to go offline after AI uncovered critical flaws "Core Lightning team sounds the alarm as AI uncovers critical flaws. To be clear, there has been no exploit. This is saying there are flaws that could be exploited." "This is Lightning, the very popular L2 on Bitcoin that's existed forever, that many systems are built on, that allows you to send Bitcoin and other things cheap and almost instantaneously." "The core developers have sounded the alarm and basically said stop running your nodes. There's an emergency update that will be coming available." "Telling node operators to take their Lightning nodes offline is a pretty big deal. This isn't Ravencoin or Harmony chain, this is Bitcoin Lightning."

ColliderVM: Stateful Computation on Bitcoin without Fraud Proofs First milestone to implement a proof of concept done. The demo here simulates the whole flow using the Bitcoin Script interpreter in Rust. Hash collision based commitment scheme baby. Next milestone will be to generate transactions and submit them on Signet. Negotiating price of covenants on Bitcoin warming up.

for better understanding of how bitcoin works, i decided to build a fork called TETSUO. bitcoin uses secp256k1 ECDSA with SHA256/RIPEMD160 hashing for addresses and transaction signing. TETSUO maintains that exact same cryptographic foundation, we inherit decades of security research. but we optimized the transaction format: - sequence numbers set to 0xffffffff for full script compatibility - SIGHASH_ALL appended to the signing preimage before hashing (not after) - proper little-endian encoding throughout this meant rebuilding the entire signing pipeline. started by forking the bitcoin-core codebase, then built a complete TypeScript wallet SDK on top. implemented BIP39 mnemonic generation, UTXO selection, fee estimation, all the stuff wallets need. the critical part: client-side signing only. your private keys never touch any server. transaction is built locally, signed locally, broadcast to network. open source: (the node) (the SDK) (block explorer) understanding bitcoin meant understanding every layer of the protocol.
