3. Blocks and Blockchain

A Block is an encrypted record of data or transactions of buying and selling of cryptocurrency. It can only hold a certain amount of data, so once the limit is reached, another block is added, creating a chain of Blocks. This is called a Blockchain.

Blockchain cannot be altered, making it a secure record and information database. The records are public and stored on several different computers around the world.

4. Burning

Burning is the process of sending cryptocurrencies to an unknown wallet address that can only receive funds. This process is usually done to create an artificial scarcity of the cryptocurrency, resulting in lesser coins in circulation. This helps raise the value of the cryptocurrency.

5. Cryptocurrency


Cryptocurrency, also known as Crypto, is a digital form of currency and uses cryptography to secure transactions and their details. Its value is generally not backed by any currency, which is why it is so volatile. It is a decentralized currency native to a Blockchain network and is also referred to as Coin.

6. Crypto Wallet

Crypto Wallet, also called Hot Wallet, is a digital online wallet where you can store your cryptocurrency. These Wallets are a convenient place to store, access, receive, and transfer your cryptocurrencies. They come with a public address that is used to link your wallet with Dapps and other decentralized services and make payments via cryptocurrency easier.

7. DAO

DAO stands for Decentralized Autonomous Organization. It means an organization where the decisions related to the project, Treasury, or Blockchain are made by voting. To participate in the voting process, you must own a Governance token which is a cryptocurrency specific to that blockchain that gives voting rights.

8. Decentralization

decentralization vs centralization

Decentralization is the system where the power is distributed instead of having a central authority. Blockchains are decentralized as they require approval from most distributed nodes, making them more secure and tamper-proof.

Hacking a central server might give you access to a lot of information but hacking a decentralized system will not be effective, as one would have to hack more than 50% of the nodes to make changes.

9. Decentralized Finance (DeFi)

DeFi or Decentralized Finance is a term coined for traditional financial activities that are performed over a decentralized network. There is no middleman like Banks or Governments, and it uses blockchain technology and smart contracts to verify and secure transactions.

They are usually open-sourced, so anyone can look at the code, and their decentralized nature helps keep every user's data secure. A large number of Dapps are based on the Ethereum Blockchain.

11. Ethereum

Ethereum is a blockchain network created by Vitalik Buterin in 2015. Its native coin Ether is the second-largest cryptocurrency by market capitalization after Bitcoin. It was an alternative to Bitcoin and added Smart contracts to its blockchain, which is why Ethereum is home to several Dapps and DeFi platforms. The sub-currency of Ether is called Gwei.

Miners race to verify a transaction and add it to a block by solving a complicated cryptographic puzzle. The miner that comest first receives the reward while others are left empty-handed.

This is inefficient as it wastes a lot of energy and isn't cost-effective. This is why Ethereum is moving toward the Proof of Stake method.

This saves a lot of unnecessary use of computer resources and electricity. The more cryptocurrency staked, the higher the chances of getting chosen.
