Give personal currency sensible names / allow users to personalize the name on creation about circles-contracts HOT 8 CLOSED

We would need some kind of oversight to make sure people didn't make offensive named coins. How easily could this be automated?

Offensive I wouldn't worry about, but we should sanitize for code-injection: https://hackernoon.com/how-one-hacker-stole-thousands-of-dollars-worth-of-cryptocurrency-with-a-classic-code-injection-a3aba5d2bff0

I have thought about this before:

• We would need some kind of oversight to make sure people didn't make offensive named coins. How easily could this be automated?
• There is a gamifying element to this: I am sure there will be people who will collect a coin of each of their friends; they may also want to keep coins given them by famous people etcetera
• A cool idea that I have pondered in the past: Users can add a string to coins either when they mint them or when they first transfer them. This could serve as a way to add some kind of 'cultural history' to the system. People might just thank the reciever or congratulate them on some life event, or even just write a motivational message or a note for posterity. This would take an order of magnitude more 'monitoring', in whatever form that takes, and there are other issues, but tell me why it's a crazy idea anyway.

Recycling this issue, because it seems related ..

ERC20 has three standard 'informational' variables - name, symbol, and decimals. These are primarily used by wallets and sites like etherscan for display. Would be great if our tokens are displayed properly in as many uis as possible.

For name, I'm thinking the user should probably be able to set their own name. For decimals, it seems a system-wide (or at least hub-wide) number is the only real path (the community has been coalescing around 18). Jury is out for me on symbol - thinking this could be user set, but also could be a system-wide, like all circles tokens display as CRC or something.

And of course the final question, which is if we go with a system wide symbol, what should it be?

hello! can you give me an example of how symbols look like? I agree that people should be able to set their own name.. the decimal thing I have no clue about but the symbol seems to be important.. :)

from circles-contracts.

Probably decimal is to set which kind of decimal marker you want. (in US/UK it's . and in EU it tends to be ,)

Symbol is probably an ascii code. I vote for ©

Decimals is a weird software thing, because the evm doesn't have good support for floating point numbers. Numbers are stored as integers based on their least significant digit. So like, for 20.00 USD, the evm would store 2000 and decimals = 2. For ether, it's 18. Most tokens use 18 too. It's kind of technical thing, not something users need to think about.

Symbol is like a ticker symbol, like 'USD' or 'ETH'.

hmmm. Seems like CRC isn't taken, at least according to wikipedia (which is kinda cool cos it also means Capablanca Random Chess)

Ok, gonna go with CRC for now
