Bitcoin Basics
Bitcoin timelocks put a condition on when a spend can become valid
Bitcoin timelocks restrict when a spending transaction can become valid. They do not schedule a guaranteed payment at an exact wall-clock time.
Bitcoin Basics
A transaction in a mempool is still waiting for inclusion in a block
A Bitcoin mempool contains transactions a node has accepted but not yet seen in a block. Read pending status separately from confirmation and final payment handling.
Blockchain Fundamentals
Bitcoin block weight and byte size count data differently
Read Bitcoin block size and block weight as different measurements, with a simple calculation showing how base and witness data are counted.
Bitcoin Basics
A Bitcoin change output can send the remainder back to your own wallet
Bitcoin spends transaction outputs rather than subtracting from a single account balance. A change output can return the remainder to a wallet-controlled address.
Blockchain Fundamentals
Bitcoin’s coinbase transaction has a special job inside a block
Bitcoin’s coinbase transaction creates the block’s permitted reward rather than spending an ordinary previous output. Learn why the name does not mean the exchange.
Blockchain Mechanics
A Bitcoin dust threshold is a relay-policy detail, not a market price
Understand Bitcoin dust as a transaction-output policy concept, separating node relay rules, spending costs and the market price of bitcoin.
Consensus Mechanics
Ethereum slashing is different from missing a validator reward
Ethereum slashing is not a synonym for every validator penalty. Separate missed duties from specified slashable behaviour when reading staking information.
Blockchain Mechanics
Ethereum’s base fee and priority fee take different paths
Separate Ethereum’s base fee from the validator priority fee and read a transaction’s gas calculation without mistaking fee caps for final cost.
