A layer 2 (L2) is a network or system designed to handle transactions with help from an underlying blockchain. Learn how rollups work, what security they inherit, how bridges fit in, and what to check before using an L2.
A zero-knowledge proof lets you show that a claim is true without handing over the secret that makes it true. Learn how the cryptography works, where blockchains use it, and what it can—and cannot—protect.
A blockchain is a shared digital record maintained by a network of computers. Learn how blocks, nodes and consensus fit together, what the technology can do, and where its limits matter in practice.
A blockchain is a shared digital record that participating computers update according to agreed rules. Learn what the term means, how transactions are recorded, and where blockchain’s benefits and limits matter in 2026.
Cloud mining lets you pay a company for access to cryptocurrency mining hardware instead of buying and running the machines yourself. Learn how contracts and payouts work, what can make them unprofitable, and how to check a provider before risking money.
Crypto mining is the process that lets proof-of-work networks such as Bitcoin order transactions and secure their blockchains. Learn how miners compete, how rewards work, what equipment and costs matter, and why mining is different from staking.
Proof of Stake (PoS) is a way for blockchains to agree on valid transactions by requiring validators to put crypto at risk. Learn how staking, rewards, slashing and finality work—and what PoS does and does not guarantee.
Proof of work is a way for open blockchain networks to agree on transaction history without relying on a central operator. Learn how mining works, what it secures, and where its costs and limits lie.
SORA is a blockchain-based economic network, and XOR is its native token. Learn what the project is designed to do, how XOR fits in, what SORA Nexus means, and how to check a token or network before taking action.
Superbridge is a cross-chain transfer platform for moving supported assets between compatible networks. Learn how its routes work, what to check before bridging, and how to manage fees, delays and transaction risks.
Algorand Foundation ran a Build-A-Bull hackathon in late 2023 with a $200,000 prize pool in USDC. This guide explains what the event was, how its prize structure worked, what happened after it closed, and what builders can do with the same playbook today.
Algorand is a proof-of-stake layer-1 blockchain that records every transaction in a public, permanent ledger. This guide explains its origins, how the network reaches agreement, how its data can be read, and how collectible and museum-style projects use it.
Algorand secures its network through pure proof of stake, and holders who keep ALGO online can take part in the protocol and earn participation rewards. This guide explains how that works, how the security model operates, what risks to weigh, and where to check current rules because reward terms can change.
Avalanche is a layer 1 blockchain built for fast transaction finality and customisable networks. This guide explains its three built-in chains, the AVAX token, how validators reach agreement, and how to start safely.
Avalanche subnets are custom blockchains that run on Avalanche's shared infrastructure, each with its own validators, fee token and rules. This guide explains how they work, when a dApp benefits from one, and which trade-offs to check before building or using one.
Injective is a Layer-1 chain built for finance, so most of its dApps are trading, lending and derivatives venues, with NFTs and games as smaller areas. This guide explains how to judge which Injective dApps are worth using and how to check their current status.
Reports in the past week describe a very large theft from Binance, with ETH holders asking what it means for their funds. This guide explains what the reports say, which figures are still unsettled, and the defensive steps that apply to exchange and self-custody users.
Blast is an Ethereum layer-2 network that pays native yield on ETH and stablecoin deposits. This guide covers how it works, how to bridge onto it, what its airdrop left behind, and the risks to weigh before depositing.
Blockchains are separate networks that do not natively share assets or data, which limits liquidity, users and applications. Interoperability is the set of methods that let them exchange value and messages, and Lisk is one platform that has built its own approach to it.
Boba Network is an Ethereum layer-2 whose future for dapps and DeFi depends on liquidity, bridges and its current activity. This guide covers the stable facts, the factors to watch and how to check the network's status yourself.
Stacks is a smart contract layer that works alongside Bitcoin, letting developers write applications that use BTC-backed assets. This guide explains how the network fits with Bitcoin, how Clarity contracts are built and tested, and how to deploy a Stacks app with care.
Ethereum Classic can run smart contracts and host dapps, but its path is narrower than Ethereum's. This guide explains the factors that matter, from security and tooling to liquidity, and how to check each one yourself.
Ethereum Classic can run Solidity smart contracts, so it can host dapps, but its smaller user base, thinner tooling and proof-of-work security trade-offs shape what a builder should expect. This explainer covers how it works, where it fits, and how to check its current state.
Cardano and Solana are both proof-of-stake layer-1 blockchains, but they differ in how they reach consensus, how quickly they confirm transactions and how developers build on them. This guide explains those differences and where to check figures that change over time.
