# Abstract
|
|
|
|
Currently, the bitshares-core do not allow asset creation that start or end with a numerical character. Creation of index style assets like `CRYPTO500` are not possible.
|
|
|
|
This BSIP proposes a protocol change to allow number characters at the end of the created asset name.
|
|
|
|
# Motivation
|
|
|
|
Economical, enable more asset names to be created in the exchange.
|
|
|
|
|
|
# Rationale
|
|
|
|
No valid reason was found until now about why this is not allowed. The creation of index style assets will bring new business to the exchange.
|
|
|
|
# Specifications
|
|
|
|
Restriction in asset names are detailed in `asset_ops.cpp`:
|
|
|
|
```
|
|
/**
|
|
* Valid symbols can contain [A-Z0-9], and '.'
|
|
* They must start with [A, Z]
|
|
* They must end with [A, Z]
|
|
* They can contain a maximum of one '.'
|
|
*/
|
|
```
|
|
|
|
BSIP proposes to change third rule to:
|
|
|
|
`They must end with [A, Z0-9]`
|
|
|
|
As file where the changes are needed(`asset_ops.cpp`) do not have access to the database, we are unable to use `head_block_time()` to create the hardfork guard.
|
|
|
|
The process is more complicated and it is described as follows:(quote from @abit in github ticker: https://github.com/bitshares/bitshares-core/issues/620#issuecomment-364803143):
|
|
|
|
"To make the change, need to loose the validation code in `asset_ops.cpp`, add a hard fork guard code with original rule to asset_evaluator to make sure no rule change before the hard fork, add corresponding hard fork guard code in proposal_evaluator. After hard fork, those hard fork guard code can be safely removed."
