I have never seen a PoW minable coin where the block hashes aren't actually the proof of work (a bunch of zeros in front of the hash)

Why is bata designed this way? Just a general curiosity

Hi here is an example of a raw block:

{
"hash": "2959d2161759004644c9bda9ac37507a29b67b7bb3580ba1bcc610c3fa8b11d9",

"tx": [

}

If you are referring to chain work then an explanation is available here:

https://bitcoin.stackexchange.com/questions/26869/what-is-chainwork

"The chainwork value is really just the total amount of work in the chain."

I know about chain work, its the cumulative work on the chain. I was wondering about the block hash, which tells the work on the individual block. Why is it hashed this way in bata.

Example a peercoin pow block:

Code:

{
"hash": "0000000000000000ee2f9eeca90dd0708459b7e78de9c64d19bc3e73fd2d8e8a",
"size": 3790,

"previousblockhash": "4235e040578bae46616f11daa644fd1cb485db7c6a5948f5e40608785aa4a6b8",
"nextblockhash": "00000000000000011b4841bb4aead702f2e266ba645b7484c3a239bf67101f3d",
"flags": "proof-of-work",
"proofhash": "0000000000000000ee2f9eeca90dd0708459b7e78de9c64d19bc3e73fd2d8e8a",
"entropybit": 0,
"modifier": "213b2338aec7bc5a",
"modifierchecksum": "4ba28af2",
}

The proofhash is the same as the block hash.

Again I am just curious, if there is a special reason for this design decision

I fail to see any zeros in front of Bata hash.

Peercoin is sha-256.

Here is an example of Litecoin instead:
