Evaluate alternative token standards

[goeddea]

We want to use a token standard that is widespread and accepted in the market - which at the moment is ERC20.

At the same time, newer token standards may provide features that we need/can use to make our life easier.

Candidates for evaluation:

• ERC223 - ERC223 token standard ethereum/EIPs#223
• ERC777 - ERC777 Token Standard ethereum/EIPs#777 - this has authorization for "operators" which can update token balances

the current token is using the zeppelin reference implementation: https://github.com/xbr/xbr-protocol/blob/master/contracts/XBRToken.sol

but I agree: the (unfixable) bugs in the ERC20 token (API) .. bad.

I've looked into both of the newer proposal you mention, and I am +1 on ERC777, and -1 on ERC223.

Reason: only ERC777 is backward compatible with ERC20.

• ERC777 Token Standard ethereum/EIPs#777

see https://github.com/PhABC/ethereum-token-standards-list/blob/master/README.md for a bigger list.

because of #22, ERC-865 and ERC-965 are of particular interest.

Right now, we are using the standard/battle-tested openzeppelin erc20 token implementation (https://github.com/crossbario/xbr-protocol/blob/master/contracts/XBRToken.sol).

I don't think the additional features of alternative tokens justify the risks and hassles of migrating - at least for now. closing: won't fix (at this point)

so rgd the token used in markets: we have redesigned this, and now allow any ERC20 token as a means of payment when creating the market https://xbr.network/docs/protocol/api/index.html#createmarket

consequently, this issue is kinda void

consequently, this issue is kinda void

it is, for market coins, but not the xbr network token

we now have market specific coins
