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.

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).

What is PoW? What is mining? Which blockchains use the PoW? Pros and cons of PoW.

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.

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.

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.

Layer 2 is a protocol built on top of an existing blockchain (layer 1) for increased performance and output. This is achieved without compromising the security of the blockchain. With the rise in the number of users and transactions on layer 1 blockchains like Bitcoin and Ethereum, there is a need for increased throughput without compromising security and decentralization.

A fork occurs when a change to the protocol is proposed and two distinct groups of nodes follow different sets of rules, creating two separate blockchains.
