Blockchain Industry Terms
1. Utility Token
A utility token grants holders the right to access a specific service or platform.
Example:
Utility tokens are often used as payment for services within decentralized applications (dApps).
6. Public Chain (Public Blockchain)
A public chain is a fully decentralized blockchain where anyone can participate in transaction validation.
Example:
Bitcoin and Ethereum are public blockchains that allow open participation.
Key Features:
- No central authority.
- Transactions are transparent and immutable.
7. Scalability Issues
Scalability issues refer to bottlenecks in transaction processing speed due to blockchain size limitations.
Example:
Ethereum’s high gas fees highlight its scalability challenges.
8. Gas Fee
Gas fees are transaction costs on the Ethereum network, paid in ETH.
Example:
High network congestion increases gas fees.
9. Liquidity Mining
Liquidity mining incentivizes users to provide liquidity to decentralized exchanges (DEXs) by rewarding them with governance tokens.
Example:
Platforms like Uniswap reward liquidity providers with trading fees and tokens.
10. DeFi (Decentralized Finance)
DeFi refers to blockchain-based financial services (e.g., lending, trading) without intermediaries.
Example:
Compound and Aave enable decentralized lending/borrowing.
11. Proof of Stake (PoS)
PoS is a consensus mechanism where validators stake crypto to secure the network (vs. energy-intensive Proof of Work).
Example:
Ethereum’s transition to PoS aims to reduce energy use.
12. dApps (Decentralized Applications)
dApps run on blockchains (e.g., Ethereum) and operate without centralized control.
Example:
Crypto games (e.g., Axie Infinity) and DEXs are dApps.
What Is Blockchain?
Blockchain is a decentralized digital ledger that records transactions across a peer-to-peer network.
Key Features:
- Immutability: Data cannot be altered once recorded.
- Transparency: All participants view the same ledger.
- Security: Cryptographic hashing prevents fraud.
Real-World Uses:
- Cryptocurrencies: Bitcoin, Ethereum.
- Smart Contracts: Self-executing agreements (e.g., NFT sales).
- Supply Chain: Tracking goods from origin to consumer.
FAQs
Q: How does blockchain ensure security?
A: Through cryptographic hashing and decentralized validation (e.g., mining/staking).
Q: What’s the difference between Bitcoin and blockchain?
A: Bitcoin is a cryptocurrency; blockchain is the underlying technology enabling it.
Q: Can blockchain be hacked?
A: Extremely difficult—it requires controlling 51% of the network’s power.
