3a. What is a Cryptocurrency?


A cryptocurrency, is an array of binary data which is developed to work as a means of exchange, personal coin ownership information are saved in a ledger that is a computerized database using sturdy cryptography to stable transaction information, to manipulate the advent of extra coins, and to confirm the switch of coin ownership. A distinguishing feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them immune to government interference or manipulation.

Cryptocurrency is digital or virtual, not in a physical form (like like the local currency) and is generally not issued by a central authority. Cryptocurrencies is recognized under a decentralized system as against the central bank currency. But it can also be considered centralized when a crypto coin is issued by a single issuer.

Cryptocurrency are stored in wallets, either a mobile wallet or an online wallet. Many people uses a mobile wallet, like trustwallet, bitcoin wallet and many more to store their cryptocoin. It is said that their money is in their hands.

b) What is Cryptography and how does it make cryptocurrencies secure?


The word "crypto" means "secret" while the word "graphy" means to "write". Therefore, " cryptography" means the capacity or the ability to send messages that can only be read by the premeditated receiver. cryptography technology can ensure relatively full anonymity, depending on the structure. the security of the transactions carried out by by individuals is protected and independent of any central authority.

Cryptography technology is used for many purposes, some of which are ensuring the security of various transactions that occur on the platform, for verification of the transfer of digital assets and tokens. And for controlling the creation of new currency

how does it make cryptocurrencies secure?

Cryptography makes cryptocurrencies secure due to the fact that cryptocurrency rely on modern asymmetric encryption techniques. Holders of cryptocurrency use the private key as a proof of ownership for their cryptocoin or cryptocurrency. Transactions made on a network are secured, using hashing and blockchain encryption methods/techniques.
