ERC20 tokens are the most common type of token built on top of Ethereum. They are fungible in nature, meaning that there isn’t a distinction between individual tokens. For example, if I have 100 metal marbles in my hand that are all the same size and color, it doesn’t matter which one I give you. In the same way, if I have 100 of the same ERC20 token, it doesn’t matter which one I give you. This contrasts with ERC721 tokens which are non-fungible tokens (NFTs) such as cryptokitties. ...

tags: Solana, Solana 101: 1. Develop Model Account: a Memory region The solana term for a memory region is “account”. Some programs own thousands of independent accounts. Programs own accounts, aka the owner of accounts. Transactions and Accounts You can make a program read and write data by sending transactions. Programs provide endpoints that can be called via transactions (In reality it’s a bit more complex than that but frameworks like Anchor abstract away this complexity). A function signature usually takes the following arguments: ...

tags: Solana, Solana 101: 1. Develop Model Program Owns Accounts And each memory region has a program that manages it (sometimes called the “owner”). How to Communicate with Solana Programs? Off-chain This means your programs aren’t on-chain program, you can submit transactions with instructions to the network, it could be done via the JSON RPC API or any SDK built on top this API.
