Ethereum transactions carry more than value — they trigger computation. Here's how the account model, gas mechanism, EVM execution, and EIP-1559 fee market work together.

A Bitcoin transaction is a cryptographically signed message that transfers ownership of unspent outputs from one address to another. Understanding the UTXO model, digital signatures, and confirmation process explains why Bitcoin behaves the way it does.

The metaverse in crypto refers to blockchain-anchored virtual environments where digital ownership is recorded at the protocol layer rather than controlled by a central platform. This post explains how it works, where the constraints live, and what would need to change for the concept to move beyond its current footprint.

Web3 describes an internet architecture built on public blockchains for ownership, identity, and value transfer without platform intermediaries. Here's how the model actually works — and where the gap between idea and reality currently sits.

A memecoin is a cryptocurrency whose primary value driver is social attention rather than technical utility or economic mechanism. Here's how the system actually works — and why most collapse while a few endure.

Dogecoin is a proof-of-work blockchain forked from Litecoin in 2013, with no supply cap and ~1-minute block times. This post explains the mechanism, the design tradeoffs behind unlimited inflation, and what the sparse development environment means for the network.

Polkadot is a relay chain connecting independent blockchains (parachains) under shared security. Parachains inherit Polkadot's validators rather than bootstrapping their own, and communicate cross-chain through XCM.

Cosmos is a network of independent blockchains that communicate natively via IBC. This post explains the hub-and-zone architecture, how the Inter-Blockchain Communication protocol works, and where the system's real constraints live.

Avalanche achieves sub-two-second finality through repeated random subsampling — a different class of consensus design. Here's how the mechanism works, where the tradeoffs live, and what the subnet architecture actually means.

Polygon is Ethereum scaling infrastructure — a sidechain with cheap fast transactions and a growing suite of ZK-proof technology. This post explains how Polygon PoS works, how it differs from true rollups, and what is changing with the ZK transition.

BNB Chain is a smart contract blockchain developed by Binance that runs Ethereum-compatible applications at low fees. This post explains how it works, what its validator structure means for trust, and what would change your understanding of it.
