Referral code based on Query ID

[oleganza]

This is a proposal to split query ID in two halves: app identifier and the random app data.

Specification

[mr-tron]

Please add algorithm for creating first part. I suggest to user CRC32 IEEE like for tlb schemes.
for example

crc32('tonkeeper') = 0x546de4ef
crc32('dedust') = 0xc671412d

I think it need to be explicitly mentioned that this data can be used only for offchain analysis and can not be fully trusted.

[oleganza]

@mr-tron @EmelyanenkoK added notes as you suggested. Please review.

[howardpen9]

looks cool for me.

But what is the impact for this to DeFi like STON.fi and DeDust?

I remember they use query_id in zero only I am afraid.

Second 32 bits (low bits) are reserved for arbitrary use: identifying individual queries in smart-contracts...

By the way, is there any onchain usecase which would allow to "identify individual queries" securely? I have not seen one so I guess main (and probably the only) usecase for query IDs is optimizing blockchain indexers.
