AltCoins

Altcoin est la combinaison de deux mots « alt » et « coin » et inclut toutes les alternatives au Bitcoin. Les altcoins présentent souvent des différences sous-jacentes par rapport au Bitcoin. Par exemple, Litecoin vise à traiter un bloc toutes les 2,5 minutes, plutôt que les 10 minutes de Bitcoin, ce qui permet à Litecoin de confirmer les transactions plus rapidement que Bitcoin. Un autre exemple est Ethereum, qui dispose d'une fonctionnalité de contrat intelligent qui permet d'exécuter des applications décentralisées sur sa blockchain.
