Blockchain Basics: The Most Important Common Terms and Concepts You Need to Know

Here are some common blockchain terms and their definitions:

1. Blockchain: A decentralized, digital ledger of transactions that is secured through cryptography. Each transaction is recorded on multiple computers, making it virtually tamper-proof.
2. Cryptography: The practice of secure communication, which involves encoding messages in such a way that only the intended recipient can decode them.
3. Decentralization: A system in which power is distributed among multiple parties, rather than being centralized in a single authority.
4. Digital ledger: A record of transactions that is maintained and updated electronically.
5. Cryptocurrency: A digital or virtual currency that uses cryptography for security and is decentralized, meaning it is not controlled by any central authority.
6. Mining: The process of verifying and adding transactions to the blockchain. Miners use specialized computers to solve complex mathematical problems, and in return, they are rewarded with cryptocurrency.
7. Wallet: A digital storage location for cryptocurrencies. A wallet can be software installed on a computer or phone, or it can be a hardware device.
8. Smart contract: A self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein are replicated and stored on the blockchain network.
9. Consensus: The process of verifying and approving transactions on the blockchain. Consensus is reached when all parties agree on the state of the blockchain.
10. Node: A computer that is connected to the blockchain network and participates in the consensus process by validating transactions and adding them to the blockchain. Nodes can be full nodes, which store a copy of the entire blockchain, or lightweight nodes, which do not store the entire blockchain but still participate in the consensus process.
