Well, time to take a look at Solana, which looks like an interesting crypto project.
Cursory review of the docs, ooh they say they're based on the research of a Turing prize winner. Claiming theoretical 710,000 transactions per second.
It's a proof of stake coin.
Whoa, silver, 17.6 billion transactions, and currently averaging about 700 transactions per second. Theoretical max of 710k tps, so they're only at 0.1% of theoretical max.
They're going to be doing weekly office hours.
Notes from the Twitch stream
- Accounts are like files.. and you need to pay rent to store them
- Max size of storage is 10MB
- If you pay 2 years rent, then it becomes rent free
- Smart contracts don't hold any state
- Program derived accounts (PDAs)
- an account that doesn't have a private key
- can only be signed by the program
- basically holds state for the program
- Smart contracts cannot themselves create accounts; accounts have to be created beforehand
- solana-program-library has reference implementations in Rust on github
- Other libraries exists to interact with the RPC (Remote Procedure Calls) server
- No serialization preference, you have to choose the library
- Fungible and Non-Fungible Tokens are the same just with limit of 1 for NFTs
- There's a wormhole bridge between Ether and Solana
- 200k operations per instruction max
- calculate fees based on number of signers
- not number of operations
- In order to create a wrapped Sol you add add the Native Mint hardcode address
- Native asset vs Sol token : what does this mean?
- The max number of accounts on a transaction
- SOL transaction are limited by UDP frames - 1200 bytes that can be used by the transaction,
- each account address is 32 bytes, so max 30 addresses
- way around it would be to split into multiple transactions
- Fake randomness: how to do it
- suggests offchain randomness
- time is not a good source of randomness
