9. Mining Safecoin
Every mining interval, the Pmid Manager group around a vault will perform the mining for
that vault. The Pmid Manager will generate a Random Attempt Target (R.A.T) based on the
following calculation:
R.A.T = Sign(Hash( (merkle_tree_root + msg_id) XOR R.A.T prev ))PmidManagerGroup ------ 4
where : merkle_tree_root is generated from all the chunks stored on that vault
msg_id is the agreed random ID among the Pmid Manager group.
Sign()PmidManagerGroup means the PmidManager group in charge shall sign the hashed
result. This makes RAT as proof of mining, allowing other vaults to verify.
The R.A.T will then be sent to the Data Manager as a PUT request, claiming the ownership
of that token on behalf of that vault. If DataManager has no record of a token data bearing
same token_index (first 32 bits), the token data will be passed to PmidManager to be held,
and the correspodent MaidManager will be notified of the success. Otherwise, the request
will be muted.
The mining interval allowed for a vault is determined by its contribution to the network. The
