Understanding 51% Attacks in Blockchain Networks
A 51% attack occurs when a single entity controls most mining power, enabling them to manipulate transactions, double-spend coins, and undermine trust in a blockchain network.
Understanding Multisig: Multi‑Signature Bitcoin Security
Multisig, or multi-signature, enhances bitcoin security by requiring multiple private keys to authorize a transaction, reducing single-point-of-failure risk for individuals and organizations.
Understanding Proof of Work in Bitcoin Security
Proof of Work is the backbone of bitcoin’s security. It requires miners to solve complex puzzles, making attacks costly and protecting the network’s integrity and transaction history.
Understanding Bitcoin Transaction Confirmations and Security
bitcoin transaction confirmations measure how deeply your payment is embedded in the blockchain. More confirmations generally mean higher security against reversals.
Bitcoin’s Biggest Risks: Regulation, Tech, and Trust
bitcoin faces major risks beyond price swings: uncertain regulation, potential technical flaws or attacks, and fragile trust in exchanges, developers, and the broader ecosystem.
Understanding Hardware Wallets for Bitcoin Security
Hardware wallets store bitcoin private keys offline, shielding them from malware and phishing. By isolating signing operations, they greatly reduce the risk of theft and unauthorized access.
How Many Confirmations Make a Bitcoin Payment Safe?
bitcoin transactions are often considered safe after a certain number of confirmations, but how many are truly enough? This article explains what confirmations mean and how to assess risk.
Understanding Multisig: Multi-Signature Bitcoin Security
Multisig, or multi-signature, enhances bitcoin security by requiring approvals from multiple private keys. This reduces single-point-of-failure risks for wallets, businesses, and shared funds.
Can Bitcoin Be Hacked? Network Secure, Users Vulnerable
bitcoin’s blockchain is highly secure against attacks, but users and exchanges remain vulnerable to hacks, scams, and key theft. Strong practices and custody choices are crucial to protect funds.
