Registered Tokens

[kroggen]

Only registered ARC1 and ARC2 tokens will appear on the Token section of AergoScan

At the same time, we may use a different strategy from other blockchains:

Instead of allowing many tokens with the same symbol, we may limit to only 1 token with a given symbol

This has one advantage: it is easier for people to sign transactions, as instead of displaying the token address, it can display the token symbol. Then the symbol can be "resolved" to the address on chain

If registered tokens were used only by aergoscan, then it could be stored on an external database.
But if also used on-chain, then it must be done on a smart contract.

It can be a dedicated contract with the purpose of storing registered tokens, or even a "name service"

I am writing a contract from scratch for the purpose of storing registered tokens

It may support these queries:

symbol -> address

Used to resolve a symbol to the contract address

symbol -> all metadata

Similar to above, but returns the entire table

address -> symbol

Used to check if a contract is registered
It returns null if not

If any other queries are required, please inform

[kroggen]

Such a contract cannot be controlled by a single person

It should work like a DAO, requiring confirmation from other members
