A fundamental part of any blockchain ecosystem, including cryptocurrencies like Bitcoin or Ethereum, is the concept of a ‘wallet’. These digital wallets don’t hold money in the conventional sense; instead, they store cryptographic keys – single key or multisig (multi-signature) keys, that allow users to send or receive cryptocurrency on a blockchain network.  Let’s dive in to discuss these two options, outlining their advantages and disadvantages to provide a comprehensive understanding. Single Key Wallets Single key wallets are the simplest form of blockchain wallets. In this setup, the ..read more

As multisig technology develops, it becomes more and more relevant to the cryptocurrency world. Multisig wallets are much more potent than before, which brings them closer to practical usability for crypto holders. Essentially, what they allow you to do is create a peer-to-peer security network where each point has to verify a transfer. In other words, there’s no single point a hacker can attack to create a security breach and initiate a fraudulent transfer. In a way, they work similarly to cryptocurrencies themselves, which rely on the blockchain to maintain their stability. As such, it’s no ..read more
