+Solana is a high-performance blockchain designed for mass adoption. Compared to rival blockchains like [[Ethereum]], it offers super-fast 400ms confirmation times and low transaction fees, with a median fee of 0.00064 SOL per transaction. Solana aims to provide the best experience for developers and users to build and use decentralized applications.

 ## Technical Details
 
 ### Innovative Consensus Mechanism
 
+Both Ethereum and Solana use a consensus mechanism called [[Proof of stake]] (PoS). Solana introduces an innovative global clock design called Proof of History (PoH), which arranges the sequence of blocks, transactions, and events. In the event of a fork, Solana can quickly resolve it using PoH, whereas Ethereum validators need to calculate attestations from the genesis block to the latest block, which is time-consuming.
+
+### On-Chain Programs
 
+In Solana, [[Smart Contract]]s are referred to as "on-chain programs" and are written in Rust. Each program is an on-chain account that stores executable logic, organized into specific functions called instructions. There is a framework called [Anchor](https://github.com/coral-xyz/anchor) that helps developers write, test, and deploy on-chain programs efficiently.
 
-### On-Chain Program
+### Account Model
+The most significant difference between Solana and Ethereum is the account model. In Ethereum, each account can be either an Externally Owned Account (EOA) or a Contract Account, where the contract logic and storage are tied together. In Solana, the contract account and storage account are separated, making contract accounts completely stateless.
