CCN » What is Cryptocurrency?
USD, but designed for the purpose of exchanging digital information through a process made possible by certain principles of cryptography. Put another way, cryptocurrency is electricity converted into lines of code with monetary value. In the simplest of forms, cryptocurrency is digital currency. Most cryptocurrencies are designed to decrease in production over time like Bitcoin, which creates a market cap on them. That’s different from fiat currencies where financial institutions can always create more, hence inflation. Bitcoin will never have more than 21 million coins in circulation.
The technical system on which all cryptocurrencies are based on was created by Satoshi Nakamoto. The first cryptocurrency was Bitcoin. Bitcoin was created in 2009 by a pseudonymous developer named Satoshi Nakamoto. Bitcoin is a cryptocurrency that is based on the proof-of-work system. DNS to make internet censorship more difficult.
Paypal for cryptocurrencies that supports any fiat currency, cryptocurrency, commodity or even frequent flier miles. Bitcoin is the largest cryptocurrency in both market capitalization, volume, acceptance and notoriety, but it’s not the most valuable coin. What is a Cryptocurrency Hash? Cryptocurrency mining power is rated on a scale of hashes per seconds. Every time a miner successfully solves a block, a new hash is created. A hash algorithm turns this large amount of data into a fixed-length hash.
Like a code if you know the algorithm you can solve a hash and get the original data out, but to the ordinary eye it’s just a bunch of numbers crammed together and remains practically impossible to get the original data out of. The different hashing functions were adopted to answer concerns with the SHA-256. Before, individuals were able to mine Bitcoin with their GPU’s, which require a large amount of energy. But as Bitcoin grew in popularity, ASIC SHA-256 machine were built which made GPU mining obsolete. To give you an idea of just how powerful these machines are, a mining rig running 4 GPU’s would get a hash rate of around 3. This effectively killed GPU mining and left many individuals worried about the security of the network. With less individuals being able to profitably mine from their home computer, the network become less decentralized.
Scrypt mining was implemented with the promise of being ASIC resistant due to the memory problem it introduced. Scrypt hashes require lots of memory, which GPU’s are already designed to handle and ASIC machines were not. Scrypt also taut that their proof-of-work is much more energy efficient than SHA-256. Bitcoin blocks are solved at a rate of 1 per 10 minutes while Litecoin blocks are solver at a rate of 1 per 2.
The security of cryptocurrencies is two part. The first part comes from the difficulty in finding hash set intersections, a task done by miners. Even at this point the attacker is limited to what he can do. The attacker could reverse his own transactions or block other transactions.
