Analyzing Mining Pool Behavior to Address Bitcoin Core’s Double Coinbase Reservation Issue
Written by Sadiq Ismail In theory, Bitcoin Core’s block-building algorithm reserves 4,000 WU for miners’ coinbase transactions. This means it should generate a block template with a weight of 3,996,000 WU. However, in practice, this is not the case due to an accidental double-reservation bug (see

Schnorr Signatures: A Solution to ECDSA's Malleability in Bitcoin Transactions
Written by Sadiq Ismail In our journey to understand Bitcoin's cryptography, we've already seen how the ECDSA (Elliptic Curve Digital Signature Algorithm) plays a key role in securing transactions. But, as Abubakar Sadiq Ismail pointed out in his previous piece, ECDSA comes with a notable vulnerability;

ECDSA Digital Signatures
Written by Sadiq Ismail Digital signatures are crucial for ensuring the authenticity and integrity of digital documents, offering a level of security that physical signatures simply can't match. Among the various digital signature algorithms available, the Elliptic Curve Digital Signature Algorithm (ECDSA) stands out for its efficiency and

Bitcoin Block Construction Using Rust: A Step-by-Step Guide
Written by Collins Okafor A Bitcoin block is a fundamental component of the Bitcoin blockchain, acting as a container for a group of transactions. Each block is linked to the previous one, forming a secure chain of data. At the heart of each block is a block header, which includes

Blinded Diffie–Hellman–Merkle for Ecash Mints
Written by Charles Chege Ecash, conceptualized by David Chaum in the 1980s, was one of the first attempts to create anonymous digital currency. Chaum's idea used cryptographic proofs to mint and manage electronic tokens, ensuring the privacy of transactions through blinded digital signatures. These early ideas laid the

Initial Peer Discovery in Bitcoin
Written by Aurelia Naiyoma In the Bitcoin Network, peer discovery is an essential process that ensures nodes can effectively connect and exchange information. This plays a critical role in securing the network by ensuring blocks are propagated and transactions can be validated, forming the core basis of how the network

Merkle Trees Implementation In Git and Bitcoin
Written by Aurelia Naiyoma Imagine an instance where every tiny code change is traceable, and transactions are secured with unbreakable chains of verification. This is the power of Merkle trees, a deceptively simple data structure at the heart of systems like Git and Bitcoin. Merkle trees work by converting data

HODL Invoices vs BOLT11 Invoices: A Comparison
Written by Oghenovo Usiwoma Lightning is a second layer for Bitcoin that uses micropayment channels to scale the blockchain’s capability to conduct transactions more efficiently. This layer consists of multiple nodes that can open and close payment channels with each other, without having to broadcast every transaction to the

Types of Backups In The Lightning Network
Written by Ibironke Marvellous The Lightning Network is a second-layer payment protocol built on the Bitcoin network. It is designed to improve the scalability of the Bitcoin network and provide near-instant, low-cost transactions. In contrast, the Bitcoin network is a first-layer payment protocol that supports secure, decentralized transactions. The Lightning

Transaction Malleability In Bitcoin: What Is It and Why It Matters
Written by Nasser Saazi One of the most fundamental properties of Bitcoin as a medium of exchange is that transactions, once made, remain valid and cannot be double spent. When Alice pays Bob, she wants the assurance that the payment made can never be invalidated. This is critical to the

Why a Bitcoin Address Is Not Like An Account Number
Written by Abubakar Sadiq Ismail Bitcoin address is a set of alphanumeric characters which can also be encoded in a QR code format, bitcoin addresses have uniform prefixes 1, 3, bc1 etc., and each prefix type has a meaning. Bitcoin addresses are used to receive bitcoin payments from other bitcoin
