The only overlap is to make it so miners can search for proof-of-work for both networks simultaneously.<br/><br/>The networks wouldn't need any coordination. Miners would subscribe to both networks in parallel. They would scan SHA such that if they get a hit, they potentially solve both at once. A solution may be for just one of the networks if one network has a lower difficulty.<br/></div><br/>This sounds very very interesting, something to explore.<br/><br/>Can you elaborate on how would it work in practice? Separate networks and block chains implies hashing one block header for each network, with different resulting hashes, does it not?<br/><br/>The only thing I can come up with is the completely naive and slightly cache-unfriendly implementation...<br/><br/>while (nonce < 0xffffff)<br/> nonce++<br/> for each network<br/> data_block[nonce_offset] = nonce // ie. our nonce<br/> scanhash(data_block)<br/><br/>or<br/><br/>for each network<br/> while (nonce < 0xffff)<br/> data_block[nonce_offset]++<br/> scanhash(data_block)<br/><br/>I could easily update cpuminer to poll multiple RPC endpoints for 'getwork'...<br/></div> text/html
