Understanding TPS: Which Blockchains Are the Fastest?

Transaction per second (TPS) in blockchain is a metric that measures the number of transactions a blockchain can process in a second.  TPS indicates the number of transactions a network can process per second. A high TPS is often associated with increased throughput, efficiency, and enhanced capacity for handling transactions/operations, thus making it a key […]

What Are Blockchain Oracles?

A blockchain oracle is a third-party service that provides external data to smart contracts, enabling them to access real-world or off-chain data. This access allows smart contracts to execute based on inputs and outputs from off-chain data, ultimately determining the outcomes of certain smart contracts. Blockchain oracles bridge the gap between smart contracts and the […]

Everything You Need To Know About Multisig Wallets

Multisig wallets, also known as multisignature wallets, are cryptocurrency wallets that require multiple signatures to approve and execute transactions, rather than just one. Each signature used to authorise a transaction is associated with a different private key and the wallet has an already predefined  minimum threshold of signatures required to sign before a transaction is […]

What is an Ethereum Virtual Machine (EVM)?

Ethereum Virtual Machine (EVM) is a decentralised runtime environment that executes smart contracts, processes transactions, updates account balances and has memory to save information thus maintaining the state of the Ethereum blockchain.  The software runs across the thousands of nodes that make up the Ethereum network, meaning the EVM doesn’t have a central computer or […]

What is DePIN (Decentralised Physical Infrastructure Networks) in Crypto?

From time to time, a disruptive and innovative protocol or narrative emerges in the blockchain and crypto space, gaining momentum and capturing widespread attention. These innovations reflect the boundary-pushing nature of participants in the Web3 ecosystem. In this article, we will explore one such innovation: Decentralized Physical Infrastructure Networks (DePINs). This rapidly growing narrative has […]

Understanding and Preventing Reentrancy Attacks in Crypto

A reentrancy attack is a vulnerability exploit where an attacker takes advantage of the asynchronous nature of certain operations in a smart contract to repeatedly call a function before the previous call is complete.  This loophole allows for repeated execution of actions intended to occur only once enabling attackers to manipulate the contract’s state leading […]

What is Maximal Extractable Value (MEV) In Crypto?

Maximal extractable value formerly known as miner extractable value is the maximum profit a block producer( miner or validator) can get by/from manipulating the ordering and arrangement of transactions in a block before they are added to the blockchain.  The concept started gaining popularity when DeFi protocols and DEXs emerged on the Ethereum network. The […]
