Arbitrage trading is a relatively low-risk trading strategy that takes advantage of price differences across markets. Most of the time, this involves buying and selling the same asset (like Bitcoin) on different exchanges. Since the price of Bitcoin should, in theory, be equal on Binance and on another exchange, any difference between the two is likely an arbitrage opportunity.

In short, a DoS attack (or Denial-of-Service attack) is a method used to disrupt legitimate users' access to a target network or web resource. Typically, this is accomplished by overloading the target (often a web server) with a massive amount of traffic - or by sending malicious requests that cause the target resource to malfunction or crash entirely.

A dusting attack refers to a relatively new kind of malicious activity where hackers and scammers try and break the privacy of Bitcoin and cryptocurrency users by sending tiny amounts of coins to their wallets. The transactional activity of these wallets is then tracked down by the attackers, who perform a combined analysis of different addresses to deanonymize the person or company behind each wallet.

Market trends are among the most fundamental aspects of financial markets. We can define a market trend as the overall direction that an asset or a market is going. As such, market trends are closely watched by both technical analysts and fundamental analysts.

A consensus algorithm is a mechanism that allows users or machines to coordinate in a distributed setting. It needs to ensure that all agents in the system can agree on a single source of truth, even if some agents fail. In other words, the system must be fault-tolerant (see also - Byzantine Fault Tolerance Explained). In a centralized setup, a single entity has power over the system. In most cases, they can make changes as they please – there isn’t some complex governance system for reaching consensus amongst many administrators.

A digital signature is a cryptographic mechanism used to verify the authenticity and integrity of digital data. We may consider it as a digital version of the ordinary handwritten signatures, but with higher levels of complexity and security.

You probably know the drill with cryptocurrency exchanges. Sign up with your email, come up with a strong password, verify your account, and start trading cryptocurrency. Decentralized exchanges are like that, minus the hassle of sign-ups. In most cases, there’s no depositing or withdrawing crypto. The trade happens directly between two users’ wallets, with limited (if any!) input from a third-party.
