Signed Proof-of-Work
“Marathon Digital Holdings announced on March 30, 2021 the launching of the first Bitcoin mining pool in North America that is fully compliant with the United States regulations, including anti-money laundering and the Office of Foreign Asset Control's standards.
The mining process will include an algorithm that is able to exclude transactions from personas that are named on the Department of Treasury's Specially Designated Nationals and Blocked Persons List.
This reminds us of the importance of censorship resistance and proves that any centralization of mining, including mining pools is bad.
Therefore we are going to introduce botnet and mining pools resistant solo mining, so-called “Signed Proof-of-Work”. Main idea behind SPoW algo is to sign header data with the private key of the miner and that the address in the coinbase transaction correspond to this key. For CryptoNote this is a bit more complicated to implement but we know how.
To make it even more resilient we will probably add our another in house developed botnet and pool resistance technique, called BloDHa.
Stay tuned...
