Algorithmic trading uses computer programs to execute trades automatically based on predefined rules, mathematical models, and technical indicators without human intervention. These algorithms (bots) can process market data, identify patterns, and execute thousands of trades per second far faster than humans. Algorithmic trading has grown significantly in crypto markets, with institutions and hedge funds using sophisticated systems that respond to Fibonacci levels, moving averages, order book depth, and liquidity conditions.

Auto-deleveraging (ADL) is an exchange mechanism that forcibly closes profitable leveraged positions to cover losses from underwater accounts and maintain platform solvency during extreme volatility. When liquidations cascade faster than the exchange can process, ADL systems automatically close winning traders' positions, taking their profits, to ensure the exchange doesn't become insolvent. This typically affects 0.5-2% of highly profitable positions during crashes, meaning your hedge or winning short can disappear exactly when you need it most.

Gas fees are the transaction costs paid to blockchain network validators for processing and confirming cryptocurrency transactions, calculated based on network congestion and transaction complexity. These fees are denominated in the blockchain's native currency (ETH for Ethereum, SOL for Solana) and fluctuate wildly from pennies during low activity to $50+ during peak congestion. Gas fees represent a significant cost for active traders and DeFi users, often making small transactions economically unviable.

Layer 1 refers to base blockchain protocols like Bitcoin, Ethereum, and Solana that process and finalize transactions directly on their main chain with native security. Layer 2 solutions are secondary protocols built on top of Layer 1 blockchains that handle transactions off the main chain to improve speed and reduce costs, then settle final state back to Layer 1 for security. L2s inherit security from their parent chain while offering 10-100x faster transactions and lower fees, though they add complexity and additional trust assumptions.

Proof of Stake is a consensus mechanism that selects validators based on the amount of cryptocurrency they lock (or “stake”) as collateral. Instead of using computational power, PoS secures the network through economic incentives. Validators are rewarded for confirming transactions correctly and penalized (slashed) for malicious behavior. PoS is more energy-efficient than PoW.

Proof of Work is a blockchain consensus mechanism where miners solve complex mathematical puzzles to validate transactions and add new blocks. The process requires significant computational power and energy. It’s designed to prevent spam and double-spending while ensuring network security. PoW also issues new coins as block rewards to incentivize miners.
