Even seasoned crypto enthusiasts can fall victim to online scams and hacks - here are some crypto security precautions you can take to help stay safe online.

Scams and fraud are an unfortunate reality in cryptocurrency. By learning what to look for, users can better protect themselves and their funds.

Decentralized networks like Bitcoin, Litecoin, Ethereum or Bitcoin Cash have no central authority that would validate their crypto transactions or safeguard their records.

Maintaining privacy in the digital world is getting more and more difficult nowadays. Internet giants have made it their mission to gather as much data on their users as possible. There are even companies whose sole purpose is to collect user data, with or without consent, and sell it on to others.

Learn about the benefits of using cold storage for securing cryptocurrencies and discover some tips for choosing the right cold storage solution.

When you buy something, you rely on someone to authorize that you’ve paid for the product or service. In traditional exchanges, this someone is a third party who enjoys the trust of everyone involved in the transaction.

One of the difficulties that distributed blockchain networks face is reaching an agreement on which transactions are legitimate, which blocks are valid and which chain is longest. To solve this problem, each blockchain implements a series of consensus rules to which every user, or node, must adhere.

Blockchain policy rules refer to configuration options that modify the behavior of nodes. Each node can set its own rules to serve its individual interests.

Multi-party computation (MPC) is a cryptographic protocol that enables multiple parties to compute a single function based on their individual inputs without any input being revealed to the other parties. MPC wallets are a practical implementation of MPC technology, offering benefits such as security and efficiency of fund transfer.

Digital currencies like bitcoin or ether (Ethereum) are not called cryptocurrencies without good reason. Having no physical form and no central authority to verify transfers and ownership of coins, the functionality of cryptocurrencies fundamentally depends on cryptography.

Vulnerable smart contracts have technical weaknesses of various types that can be exploited by attackers to steal funds or data.

A 51% attack (also referred to as a majority attack or a double-spend attack) is a potential attack on blockchains that are created through the process of mining.

A MultiSig wallet is a digital wallet that operates with multisignature addresses. This means that it requires more than one private key to sign and authorize a crypto transaction or, in some cases, that several different keys can be used to generate a signature.

A Sybil attack is an attack against peer-to-peer networks in which a single attacker creates many fake identities to gain an advantage in the network. Other users do not recognize these identities as fictitious, which gives the attacker a disproportionately large influence over the network.
