Crypto Fundamentals: 10 core concepts explained
This guide covers crypto fundamentals across four areas: network principles, fees and incentives, on-chain applications, and asset security. It focuses on how different blockchains operate, as well as the risks associated with private keys, seed phrases, and stablecoins. The content is for introductory learning only and does not constitute investment advice.
How Blockchains Work
A blockchain is a distributed digital ledger maintained collectively by multiple computers. Transaction data is written into interconnected blocks in chronological order and is generally difficult to alter once recorded. Decentralization means that control is distributed among network participants, but the degree of decentralization varies across networks. Smart contracts encode agreements as code, execute automatically when conditions are met, and can be used to build decentralized applications.
Consensus, Fees, and Incentives
Consensus mechanisms help networks validate transactions and maintain security. Proof of Work relies on miners investing hardware and energy to solve computational problems; Proof of Stake relies on validators staking cryptocurrency to participate in network maintenance and is generally more energy-efficient. Users submitting on-chain transactions may also pay gas fees, whose prices fluctuate with network demand. Tokenomics is used to analyze an asset’s supply, utility, and distribution.
DeFi and Stablecoins
Decentralized finance uses blockchains and smart contracts to provide services such as lending and trading. Users do not need to rely on traditional financial intermediaries, but they must still be aware of smart contract and liquidity risks. Stablecoins attempt to maintain relatively stable prices through fiat reserves, crypto-asset collateral, or algorithmic mechanisms. However, they may still depeg and may be affected by reserve management, regulation, and smart contract vulnerabilities.
Wallet Security Fundamentals
A public key can be used to receive funds, while a private key is used to prove ownership of and control the assets associated with the corresponding address. It should never be disclosed to anyone. A seed phrase usually consists of 12 to 24 random words and can restore an entire wallet and its derived private keys, so its scope of authority is often greater than that of a single private key. Store the seed phrase offline in a secure location. If it is lost or exposed, access to the funds may be impossible to recover or may be seized by others.
