The digital currency, also known as crypto currency or digital gold, is a form of payment and store of value that utilizes cryptography for security purposes. It operates independently of a central bank and relies on decentralized networks to facilitate transactions.

Digital currencies have several defining characteristics:

1. Decentralization: Digital currencies are not issued by a central authority such as a government or bank. Instead, they rely on a network of computers around the world to authenticate and verify transactions.

2. Transparent: Every transaction recorded on a blockchain is publicly viewable, from the creation of a new coin to its final transfer to a user. This transparency helps prevent fraud and corruption.

3. Security: Each transaction on a blockchain is protected by complex algorithms and cryptographic keys, making it nearly impossible for hackers to intercept or alter data.

4. Immutable: Once a transaction is added to a blockchain, it cannot be changed or deleted. This ensures the integrity of the ledger and reduces the risk of double-spending.

5. Consensus: To add a new block to a blockchain, miners (computers) must solve complex mathematical problems. Only those who solve these problems first are eligible to add a block, further ensuring the security and reliability of the network.

6. Universal: Digital currencies can be used across borders and international payments are made instantly and without the need for intermediaries like banks.

7. Digital: They are entirely digital in nature, stored and transferred electronically.

8. Interoperability: Digital currencies can be used to make purchases with other digital currencies or traditional fiat currencies.

In summary, the key features of digital currencies include their decentralized structure, transparency, security, immutability, consensus mechanism, universality, digital nature, and interoperability.
