The miner uses one of three clients to connect to the Ethereum network: Geth, Eth, or Pyethapp. With that in mind, miners typically focus on GPU processing. While CPUs can be used, GPUs have a much higher hash rate, or speed of computing hash functions than CPUs. Once the network passes a certain size and is widely distributed, this becomes impractical enough to be considered impossible.Įach miner on the network needs three things to be successful: A very large network of miners is needed to prevent this risk of fraud and corruption. In order to hack or rewrite blocks, a malicious agent would need to control at least half of the Ethereum network of miners. While the Ethereum network does not want collisions, in practice each miner would love to detect one. In the cryptocurrency world, if a collision is detected then the algorithm used to create the collision is abandoned in favor of one which is more complex and secure.īecause of the threat of collisions, a bounty is placed on detecting them. Think of this as two cars attempting to use the same parking space at the same time.īecause of the risk of collisions and the need to ensure data security, hash functions for mining operations are complex and require significant computational power. CollisionsĪ collision occurs when two different sets of data calculate the same checksum or hash function. This is the cryptographic element of cryptocurrencies and is used to ensure anonymity. Hash functions are then collected into hash tables, which can be used to quickly organize and sort data records.īecause of the nature of hash functions, algorithms can be built that will ensure the original data set cannot be reproduced from the hash function itself. It also ensures no accounting errors or ledger mistakes can occur.Ī hash function is a checksum algorithm that converts data files of arbitrary size to a data string of fixed size. In cryptocurrencies, checksums are used to make sure that once you spend your coin, everybody knows you have spent it and you can’t spend it again. If even one bit of the original data set is altered, the checksum will be altered, alerting the system to an error.Ĭhecksums are used in many computer programming situations when data is transferred or stored and there is a risk of data corruption. Hash FunctionsĪll hash functions are checksums, but not all checksums are hash functions.Ī checksum is a calculation that represents a large data set with a smaller, unique data set used to detect errors in data transmission or storage. Once validated, a new block is connected to the chain of all previous blocks and is then said to be integrated into the blockchain. Let’s take a closer look at each of these elements below.Ī blockchain is a massively distributed set of dynamic records and is essential for cryptocurrency trading.Īs records accumulate, they are collected into blocks and validated.
