How the machinery works
Gas, staking, rollups, liquidity pools and slippage — the mechanisms, so the next unfamiliar screen is one you can reason about.
-
Finality and Confirmations: When Is It Settled?
Proof of work settles by depth, proof of stake can finalise explicitly. What a reorg undoes, and why exchanges pick different confirmation counts.
intermediate -
Gas Limit vs Gas Price: What Each Number Does
Understand the difference between gas limit and gas price, what happens when the limit is too low, and why high estimates may signal contract issues.
-
How Crypto Bridges Work: Lock, Mint, Burn
Learn what a crypto bridge does with your original asset—locked, burned, or custodied—and why bridges are a top source of crypto losses.
-
How Gas Fees Work: What You Pay For
Understand what gas fees are, why they vary with network demand, and why failed transactions still cost you. Learn the base fee and priority fee split.
-
How Staking Works: Validators, Lock-ups, and Slashing
Learn the mechanics of crypto staking: validators, delegation, lock-ups, unbonding, and slashing risks. Understand what your coins actually do.
-
Impermanent Loss: How It Works and When It Applies
Understand impermanent loss: why liquidity pools rebalance against you, when it becomes permanent, and how it interacts with trading fees.
-
Layer 2 Networks: How They Work
Understand layer 2 networks: what moves off-chain, how rollups work, and the withdrawal wait. A clear, risk-aware explanation of L2 mechanics.
-
Liquidity Pools: How They Work
Learn how liquidity pools power decentralized exchanges, how fees are earned, and the risks like impermanent loss.
-
MEV and Sandwich Attacks: Ordering Has Value
A public mempool makes transaction ordering valuable. How a sandwich exploits loose slippage, and what private order flow trades away for protection.
intermediate -
Nonce and Transaction Order: Why One Stuck Blocks All
The nonce forces a strict order per account, which is why one pending transaction blocks every later one. How replacement and cancellation actually work.
intermediate -
Proof of Stake Explained: Validators, Slashing, and Lock-ups
Learn how proof of stake replaces mining with validators, what they risk, and how it differs from proof of work in practical terms.
-
Slippage in Crypto: What It Is and How to Manage It
Learn why crypto trade prices differ from quotes, what slippage tolerance authorizes, and how high tolerance invites sandwich attacks.
-
Stuck Crypto Transactions: Causes and Fixes
Learn why crypto transactions get stuck, how nonces work, and how to speed up or cancel a pending transaction. Understand the risks and what not to do.
