Blockchain

A 51% attack occurs when a group or an individual controls more than 50% of a network's computing and creates invalid transactions to steal tokens.

Proof-of-Stake (PoS) is a consensus mechanism for processing transactions and creating new blocks in a blockchain. In a proof-of-stake blockchain, the staking reward of a validator and the total amount of the staked collateral are often positively related. As each validator attempts to create a block, when a block is selected as a new block, the validator can record the transactions and receive a reward.

As the leading Ethereum layer 2 scaling solution, Optimism has hosted a series of airdrop events and made its name known to the crypto community. This article will bring you into the world of Optimism.

Sharding is a database partitioning technique that helps blockchains build scalability, allowing transactions to be processed in parallel by multiple sharding chains to reduce network congestion and increase transactions per second (TPS).

EVM is an abstraction layer between the code and the host that serves as a guarantee to maintain the smooth operation of Ethereum. What is EVM after all? What are the principles and typical use cases of EVM? Let’s dive deeper into it.

Understanding an essential encryption program for the modern age

Digital signature is one of the most important technological features in current identity verification, especially for crypto.

Polygon is a layer-2 scaling solution that was created to transcend some of the common limitations associated with Ethereum Blockchain.

A multisig wallet is a digital wallet that requires at least two or more private keys to sign in and make a transaction.

ERC-20 has emerged as the technical standard used for all smart contracts on the Ethereum Network.

A protocol that ensures mutual agreement and reliability in the blockchain network.
