In this article, we learn how a Bitcoin HD Wallet is created from a generated seed. Deterministic wallets solve the issue of address reuse and management of multiple keys by using a single seed that can be a 128, 256, or 512-bit random number as the...
In this article, we learn how to generate mnemonics and how the mnemonic is converted into a seed that is used to derive public keys for different transactions. In the prerequisites article, we learned about BIPs and their purpose in the Bitcoin bloc...

Extended Public keys, are a combination of a public key and a chain code used to create children and generate branches in the HD wallet tree structure stored as a 512-bit(256-bits each, for the keys and chain code) sequence. In this article, we will ...
Cryptography, more specifically public-key cryptography is at the heart of blockchain technology. Hashing is also used to secure transactions and prevent blockchain mutability. In public-key cryptography also known as asymmetric cryptography, we gene...
In this article, we learn about Bitcoin signature hashes that add flexibility to Bitcoin by allowing users to specify data that is to be committed in a transaction. Blockchain technologies are built upon cryptography such as elliptic curve algorithm ...
