Both a cryptocurrency and a blockchain platform, Ethereum is a favorite of program developers because of its potential applications, like so-called smart contracts that automatically execute when conditions are met and non-fungible tokens (NFTs).
Cryptocurrencies are various forms of digital money that are usually based on blockchain technology. Blockchain technology allows most cryptocurrencies to exist as “trustless” forms of transactions. This means there is no centralized authority overseeing the transactions on a cryptocurrency’s blockchain.

Created in 2009 by Satoshi Nakamoto, bitcoin (BTC) is the original cryptocurrency. As with most cryptocurrencies, BTC runs on a blockchain, or a ledger logging transactions distributed across a network of thousands of computers. Because additions to the distributed ledgers must be verified by solving a cryptographic puzzle, a process called proof of work, bitcoin is kept secure and safe from fraudsters.
Bitcoin cryptocurrency
Met een web wallet kunnen gebruikers communiceren met de BTC-blockchain via een interface op een webbrowser en worden hun persoonlijke sleutels en andere “toegangsgegevens” op een online server opgeslagen. Hierdoor is een web wallet ook een hot wallet.
Op 31 oktober 2008 publiceerde Nakamoto de whitepaper van Bitcoin, waarin in detail werd beschreven hoe een peer-to-peer online valuta kon worden geïmplementeerd. Er werd voorgesteld om een gedecentraliseerd grootboek te gebruiken met transacties verpakt in batches (“blocks” genoemd) en beveiligd door cryptografische algoritmen — het volledige systeem kreeg later de naam “blockchain.”
Papieren Wallet: als je echt ouderwets wil zijn, kun je je bitcoinadres opschrijven op een papiertje — of deze uitprinten. Deze aanpak is niet risicoloos. Als je je papieren wallet verlies, kan je BTC voor altijd verloren gaan.

What is cryptocurrency mining
As we’ve now seen, miners must hash the block header repeatedly using different nonce values. They do so until they find a valid block hash, after which the miner who found it will broadcast this block to the network. All other nodes will check if the block and its hash are valid and, if so, add the new block to their copy of the blockchain.
There are, however, efforts to mitigate this negative externality by seeking cleaner and green energy sources for mining operations (such as geothermal or solar sources) and utilizing carbon offset credits. Additionally, some jurisdictions have taken action to reduce Bitcoin’s adverse effects on the climate and environment.
Due to the halving process and increasing prices, miners want to receive as many bitcoins as possible because the supply of new coins is slowly dwindling. Sometime around 2140, there will be no more new bitcoins created.
