Has anyone floated the idea of Wrapped COMB?

You mean like Etherbrush? ^_^

It's possible to replicate/simulate haircomb cryptography in Ethereum yielding a separate haircomb-like currency (on ethereum).

In a nutshell you need 3 gobal static mappings in the contract.

Mapping from uint256 to [2]uint - the commitment set

Mapping from uint256 to uint64 - the accounts table

Mapping from uint256 to uint256 - accounts redirect table - flow graph of currency

Then you need some public accesor to add commitments. anyone can call with their uint256 value
to insert it into the commitment set. the [2]uint are assigned automatically, first is block height (block.number)
the second is a counter from 1 that increments and resets to 1 when block.number is detected to be higher.

Next when someone chooses to reveal their claim, they reveal {X uint256, H uint} so that sha3(whitepaper+X) maps to {H, 1}. when that
happens new money are generated and inserted to the accounts table according to subsidy formula (can be the original, a new dope one,
or one based on halvings). you can then change the value {H, 1} to {H, 0} in the commitment set to prevent the claimer from doing this
twice.

Next you need 4 public functions to replay comb histories into the contract.

- Trickle function. User inserts uint256, if account and redirect table contains that uint256 key, all money from account
"redirect key" is hopped to account "redirect value".

- Haircomb function. If validated (using the normal haircomb doublespend detection), creates a redirect from the haircomb
public key to the destination address.

- Liquidity stack function. The user inserts CH uint256, OUT uint256, AMT uint64. If validated that HASH=sha3(CH cat OUT cat AMT)
contains >= AMT coins in the account table, AMT coins are immediately moved to OUT, and redirect from HASH to CH is created.

- Merkle function. The user inserts decider + merkle path. Decider is validated (using the normal decider doublespend detection).
If valid, a redirect is inserted from the sha3(decider address cat merkle root) to merkle leaf that was proved using the Nth merkle
path, so that N was signed using the decider.

Bonus points:

- implement some ERC20 api so that people can insert their ethereum shitcoins and turn them to haircombs somehow, or just trade them.

- implement a hidden mint function and rug other users ^_^
