Cryptocurrency or crypto uses encryption to ascertain transactions. This simply means that advanced coding is involved in storing and transmitting cryptocurrency data between wallets and to public ledgers. The reason of the encryption is to provide safety and security.

Cryptocurrency is assembling or a collection of binary data which is designed to work as a means of exchange wherein individual coin ownership records are stored in a ledger.

Cryptocurrency is a digital currency that can be used to buy goods and services, but uses an online ledger with solid cryptography to protect online transactions. The interest part in these unregulated currencies is to trade for gain or profit, with speculators at times driving prices upwards.

Cryptocurrency is also a form of payment that can be trade online for goods and services. That is, a online payment system that doesn't rely on banks to confirm transactions. This is a peer-to-peer system that can give power to anyone anywhere to send and receive payments. Instead of being physical money that is carried around and exchanged in the real world, cryptocurrency payments exist purely as digital entries to an online database that give an account of definite transactions. Alot of companies have make available their own currencies, which is called tokens, and these can be traded particularly for the good or service that the company gives.

Cryptocurrencies deeply work by using a technology called blockchain. Blockchain is a decentralized technology stretch out to many computers that manages and records transactions. The section pleasing of this technology is its role in security.

How Secure Is Cryptocurrency?

Cryptocurrencies are mostly constructed using blockchain technology. Blockchain gives account of the way transactions are recorded into blocks and time sealed. In otherwords, it's a fairly complex, technical process, but the outcome is a digital ledger of cryptocurrency transactions which is hard for hackers to interfere with.

Q2a: WHAT IS CRYPTOGRAPHY AND HOW DOES IT MAKE CRYPTOCURRENCIES SECURE

Crptography or Cryptology is the study of protected communications techniques that gives room to only the sender and intended recipient of a message to view it's contents. In this case, data is encrypted using a secret key and then both the encoded message and secret key are sent to the recipient for decryption.

Clearly, the word Crypto represents (secret), and Graph also represents (write). Therefore, this can be visible in the sense that the medium through which information are been sent and processed through the sender or receiver without the prevention of any intermediary and it forms an unknown ecosystem in which transactions are encoded and protected by a single other.

Cryptograghy helps in verification and transactions procedures, which normally effect inside every users and offers a signature such as layout for every transactions.

The three (3) types of Cryptograghy:

Cryptograghy can be broken down into there (3) Different types.👇🏽👇🏽
▪️ Secret key Cryptograghy
▪️ Public key Cryptograghy and
▪️ Hash Functions.

Q2b: HOW DOES IT MAKE CRYPTOCURRENCIES SECURE

Cryptography has its reason of coded data, and it guarantees that all data or informations can be be able to run through, from one nodes to other secret from the general public and has been made feasible with the keys of coded data and may simplest be utilized by the legal receiver to access, process, decode and encoded informations on it normal format. With this wonderful sample, cryptocurrencies are protected and some distance far way from been stolen, due to the fact that without a key one can't open a door while it's close.
