What is Inscriptions?Bitcoin inscriptions make it possible to bind arbitrary on-chain content to a specific satoshi

What is Inscriptions?Bitcoin inscriptions make it possible to bind arbitrary on-chain content to a specific satoshi. The interesting part is not just that Bitcoin can store media, but that ordinals give one sat identity, so wallets and indexers can follow the inscribed sat as it moves through normal Bitcoin transactions.Mar 21, 202625 min read

What Is the Lightning Network?The Lightning Network matters because Bitcoin’s base layer is excellent at settlement but poor at handling many small, fast payments

What Is the Lightning Network?The Lightning Network matters because Bitcoin’s base layer is excellent at settlement but poor at handling many small, fast payments. Lightning changes the unit of work: instead of asking the blockchain to record every transfer, it records only the opening and closing of relationships and lets the transfers happen in between.Mar 21, 202625 min read

What is a Change Output?A Bitcoin payment often creates an output back to the sender

What is a Change Output?A Bitcoin payment often creates an output back to the sender. That is the change output, and it exists because Bitcoin does not let you shave value off a coin in place: a UTXO is spent whole, with any remainder explicitly returned in a new output.Mar 21, 202622 min read

What Is Child Pays for Parent (CPFP)?Child Pays for Parent solves a simple but important problem: what if a transaction is valid but underpaid, and you cannot or do not want to replace it? By attaching a high-fee child that spends one of its outputs, you can make miners care about the package rather than the weak parent alone

What is Bitcoin Script?Bitcoin Script is the small, deliberately constrained programming language that decides whether a Bitcoin spend is allowed

What is Bitcoin Script?Bitcoin Script is the small, deliberately constrained programming language that decides whether a Bitcoin spend is allowed. Its power comes not from being general-purpose, but from being narrow enough that every node can evaluate it predictably while still supporting multisig, timelocks, and Lightning-style contracts.Mar 21, 202627 min read

What Is Bitcoin?Bitcoin matters because it solved a problem that had blocked digital money for decades: how to let strangers agree on ownership without trusting a bank or operator

What Is Bitcoin?Bitcoin matters because it solved a problem that had blocked digital money for decades: how to let strangers agree on ownership without trusting a bank or operator. Its design is simple at the center but demanding at the edges, which is why Bitcoin can be both remarkably durable and frequently misunderstood.Mar 21, 202627 min read
