Blockchain is the underlying technology behind most cryptocurrencies. It is a decentralized and distributed digital ledger that stores and tracks all transactions of a given cryptocurrency. Blockchain’s distributed nature makes it resistant to tampering and censorship, while its transparency provides users full control over their own funds and the security of their transaction data. This allows for fast, secure, low-cost, and trustless financial transactions, which is why blockchain technology is becoming increasingly adopted for cryptocurrency use cases.
