Eclipse Attack

An eclipse attack is a type of attack that targets a blockchain network by isolating and surrounding a specific node or a group of nodes within the network, in order to control and manipulate their communication with the rest of the network.

During an eclipse attack, the attackers may attempt to control the targeted node's communication, block its access to other nodes, and even manipulate the information that is being transmitted. This can allow the attackers to double-spend their digital assets or launch other malicious activities that can harm the network's integrity.

Eclipse attacks are a significant threat to decentralized systems like blockchain, as they can compromise the network's security and cause significant financial losses for users. To prevent such attacks, blockchain networks usually implement various security measures, such as firewalls, encryption, and multi-factor authentication.

It's worth noting that an eclipse attack is different from a 51% attack, where an attacker gains control of the majority of the network's computing power. In an eclipse attack, the attacker does not need to control the majority of the network's computing power; instead, they isolate and manipulate a targeted node or group of nodes to carry out the attack.

Merged Mining
Merged mining, also known as auxiliary proof-of-work (AuxPoW), is a mining process that allows miners to simultaneously mine multiple cryptocurrencies that share the same hashing algorithm. In merged mining, a miner can mine blocks for one cryptocurrency while also submitting valid proofs-of-work for other compatible cryptocurrencies.
Full Node
A full node refers to a type of node in a decentralized network, such as a blockchain, that stores a complete copy of the network's transaction history and is capable of independently validating and relaying transactions.
Colocation is a practice in the financial industry where trading firms place their servers in the same data centers as the exchanges they trade on. By doing so, they can significantly reduce the latency, or delay, in their trading data, which can give them an edge over other market participants.
Bear Market
In the world of finance, a bear market refers to a market in which prices of assets, such as stocks, bonds, and cryptocurrencies, are generally declining. The term is often used to describe a market that is experiencing a prolonged period of decline, lasting several months or even years.
