# Ethereum Cheat Sheet 



Ethereum basics - Transactions, Accounts, EIPs & more



## Terminology 



- Accounts: Externally owned accounts vs. Contract Accounts.  

- Transactions: cryptographically signed instrıctions from EOAs. 

    - The tx signature: proves that the tx came from the sender (signed with the senders private key)

    - An ethereum client like geth will handle the signing process

    - There are different types of tx: regular (tx from one account to another), contract deployment, execution of a contract

    - The tx lifecycle is: 1. A ts hash is generated --> 2. tx is broadcasted to the network and added to the tx pool --> 3. A validator must pick up your tx and include it in a block --> 4. the tx will become finalized once its included

- Gas: cost of the computation required to process a transaction. 

- Block: batches of transactions with a hash of the previous block in the chain.

- EVM: Ethereum Virtual Machine defines the rules for computing a new valid state

- Node: Instance of an ethereum client software that's connected to other computers. A node has two running clients: execution client and consensus client. 

    - There are different kind of nodes that you can run: full, light, archive node

        - Full:

        - Archive:

        - Light: Instead of downloading every block, light nodes only download block headers. The light nodes can not partiicpate in ethereum consensus however they can acess the blockchain with same functionality. 

    - Client diversity is a huge topic 

- Sequencer 

- Validator 

- PoS: In PoS validators have to stake 32 ETH as collateral. In every slot a validator is randomly selected to be the block proposer. The validator bundles the transactions together, execute them and determines the new "state." 

- PoW vs PoS: Proof-of-Stake (POS) uses randomly selected validators to confirm transactions and create new blocks. Proof-of-Work (POW) uses a competitive validation method to confirm transactions and add new blocks to the blockchain.

- Flashbots Protect: node thats does not track your ip

- Flashbots for Searchers: Connects searchers to validators while avoiding the public tx mempool. 



## EIP's

Ethereum Improvement Proposals's are standarts for potential new features or processes for Ethereum.



- 4844: Porto-danksharing: sub blockchains or shards

- 4337: Account Abstraction: single type of accounts. Upgrades EOAs so that they can be controlled by a smart contract (account recovery, batch tx) and also upgrading smart contract accounst so that they can initiate transactions.
