A hardware wallet is usually a physical device that stores private keys to access crypto tokens offline. These wallets are physical devices like Key fobs or USB sticks; you can think of them as portable vaults that digitally store vital information, such as private keys, to access crypto tokens. Private keys You…

Cosmos introduction Cosmos (ATOM) is a crypto project that aims to solve issues faced by traditional networks like Bitcoin and Ethereum. These issues include low throughput, scalability issues, and high fees. Proof-of-work blockchains require massive amounts of electricity, which is harmful to the environment. Cosmos has many objectives, but its primary aim…

ERC-20 stands for Ethereum Request for Comment 20, a set of technical rules for smart contracts on Ethereum. Fabian Vogelsteller proposed ERC-20 in 2015 as a set of rules for developers to follow to build their crypto tokens on Ethereum. It provides a common set of functions used by different…

What are smart contracts? Smart contracts are self-executing computer programs that automate actions when pre-agreed conditions are met. The transactions are irreversible and trackable once these programs are executed. They allow trusted transactions to be carried out without intermediaries. How do smart contracts work? Nick Szabo, a computer scientist, first proposed Smart contracts in the 1990s and famously compared…

What is staking in crypto? Staking involves committing crypto assets to a blockchain network to participate in transaction validation. This process is used by blockchain protocols that use the proof-of-stake (PoS) consensus system. Validators earn interest on their crypto investments while also waiting for block rewards. Compared to proof-of-work (PoW) blockchains, proof-of-stake (PoS) blockchains are…

A flash loan is an uncollateralized loan that allows users to borrow crypto assets with no upfront collateral. But this loan must be paid back within the same blockchain transaction. The decentralized finance space initially offered traditional financial services such as lending, borrowing, exchanges, and options markets for crypto users…

Zero-knowledge rollups, also known as zk-rollups, are layer-2 scalability solutions. These layer-2 scaling solutions enable blockchain protocols to validate transactions faster while maintaining security and low gas fees. Zk rollups operate better than conventional layer-1 blockchains due to their ability to combine on and off-chain processes. The Ethereum network uses…

A collection of funds locked in a smart contract is known as a liquidity pool. They are used to facilitate deFi lending, borrowing, and trading. Decentralized exchanges (DEX) are based on such liquidity pools. Users who invest their crypto tokens in such liquidity pools are known as liquidity providers (LPs)…
