Blockchain, a transparent digital ledger, tags transactions with unique “hashes” and drives Bitcoin’s success. It promises to transform the digital economy by challenging norms.

Understanding the distinction between coins and tokens is crucial in cryptocurrencies. Coins like Bitcoin and Ethereum function independently, resembling traditional currency for transactions and value storage.

Tokens on existing blockchains serve various purposes, from granting access to verifying identities and tracking supply chains. Notably, NFTs authenticate uniqueness and even represent physical assets. Ether exemplifies token usage on Ethereum, facilitating immutable transactions.
