This hex representation corresponds to the locking script (scriptPubKey) in a Pay-to-Witness-Public-Key-Hash (P2WPKH) output. When a Bitcoin transaction creates an output with this script, it essentially “locks” the funds to the specified conditions. Let’s dissect an example, the following is a hexadecimal representation of a P2WPKH script: Breaking it down: Now, let’s explain each part: […]
Did the code from ChatGPT compile straight away? No. Keep reading to see what I had to fix… The Cargo file is the main reason why it didn’t compile, and interestingly the screenshot here uses the Coinbase API, but an earlier question to ChatGPT replied with code using CoinGecko. Each time the issues were with […]
If you have any interest computer science or own any money at all then learning about Bitcoin is time well spent. The best training resource that you can start with is the “Saylor Academy : Bitcoin for developers“ The video below was first broadcast 8th March 2023 and just after halfway through has a great […]
In the near future I will be demonstrating more concepts using Python code, Jupyter notebook, and Rust. I will be sharing my progress as I learn about Bitcoin, Bitcoin Core and all things related to Bitcoin’s code. I also recently passed CS120: Bitcoin for Developers with Saylor.org: Certificate : https://certificates.saylor.org/d74173c9-1dde-409b-9aa5-70603d066ce5 Run your own node All […]
Using secp256k1 Rust bindings for Pieter Wuille’s secp256k1 library, which is used for fast and accurate manipulation of ECDSA signatures on the secp256k1 curve. Such signatures are used extensively by the Bitcoin network and its derivatives. secp256k1 This article shows the code used to create a public/private keypair using secp.generate_keypair in Rust. Also, make sure […]
The idea is to use “regtest” to try out bitcoin-cli with RPC and create a wallet, create a transaction. This is not about mining, this is about the code used to “Buy” or “Sell” Bitcoin and how you can interact with the blockchain using either the bitcoin-cli or Python code. https://github.com/RGGH/bitcoin
