During the introduction of Bitcoin in 2009, a cryptocurrency was created, ie a payment instrument existing in a digital form. Moments later, more currencies began to emerge - one of them is Ethereum, the second in terms of capitalization of cryptocurrency, which, like Bitcoin, is decentralized - thanks to this, changes on the market have less impact on it. Bitcoin is the first digital currency in the world. You can use public channels to serve transactions using Bitcoin, such as shopping outlets, exchange offices, banks and the Internet. At the core of Bitcoin's idea lies a blockchain which is an open network that everyone can access - using applications, stock exchanges or shopping outlets.
Thanks to the records contained in the block chain, Bitcoin can not be released twice, stolen or changed, so that the potential user can be calm. Transactions and their history can be verified using the application. Saved transactions in the block chain are irreversible, this is based on so-called peer-to-peer networks without central computers and transaction verification systems. Bitcoin can be saved on a personal computer in the form of a transaction book file or held in a third-party site or company. Transaction books are in the form of data sets storing information about recent transactions carried out in the network, they are encrypted using cryptographic methods. Only those users whose transactions concerned relate to them have access to them.
Ethereum, on the other hand, is not as much a cryptocurrency, but a platform that one of the main features is the ability to create scripts of contracts that are saved in the code without the participation of third parties, why they can act as autonomous mechanisms. As one of the main reasons for the creation of Ethereum was to obtain a larger, more profitable currency than Bitcoin - that's why it was decided to introduce a Gas limit instead of the block size limit - this means that in one block there will be as many transactions as users paid for Gas.
That's probably enough
