The first NFT powered social platform on Solana
SPL
is a collection of on-chain programs maintained by the Solana team
SPL stands for
Solana Program Library
The SPL Token program
the token standard of the Solana blockchain. Similar to ERC20 tokens on the Ethereum network, SPL Tokens are designed for DeFi applications

Dexlab
1) is a decentralized exchange where users can mint and list SPL tokens. 2) It will provide all the standard DeFi tools, 3) as well as a GUI that facilitates the creation of SPL tokens. 4) Our Minting Lab allows users to manage all aspects of a token, as well as 5) the deployment of smart contracts that best suits their needs.
Optimistic Concurrency Control
The distributed system technique that says a centralized database can replicate itself while maintaining high availability and not compromising much on the transaction rate.
Solana tps as of apr 2021
65,000 transactions per second (TPS) with a block time of 400ms
solana block time as of apr 2021
400ms
solana tps on a standard gigabit network
(where the transactions are no more than 176 bytes large on average,) the system can support up to 710,000 TPS.
Solana tps on a 40-gigabit network
28.4 million TPS.
SRM token
the governance token of Serum.
MSRM
If you are able to collect 1 million SRM tokens, you can stack them together to form 1 MegaSRM or MSRM. Holding 1 MSRM would give you a flat 60% discount on fees.
Serum Swap
an Automated Market Maker built on Serum.
what makes Serum Swap stand out?
the fact that it is really fast. It takes the platform just 1 second to add or remove a pool or to settle a trade. 2) And guess what the gas fees are? Roughly $0.00002 [2 hundred thousandths of a dollar, or 2 thousandths of a cent] per trade! That’s it!
Serum Swap fees
Takers are charged a flat 0.30% of the total transaction value, of which, 0.25% goes to the liquidity providers (LPs), 0.4% goes to SRM burn/buy, and 0.01% goes to the GUI hoster.
What’s stopping Solana from being 710k tps?
All nodes have to be on a 1 gigabit network

Solana programs vs Eth programs with regard to state
Remember earlier I said Solana programs are stateless. They don’t hold data permanently. This is very different from the world of Ethereum smart contracts — which hold state right on the contract.
But, Solana programs can interact w/ “accounts”.
Again, accounts are basically files that programs can read and write to. The word “accounts” is confusing and super shitty. For example, when you create a wallet on Solana — you create an “account”. But, your program can also make an “account” that it can write data to. Programs themselves are considered “accounts”.
