Algorithm 1 Custom Proof-of-Work Algorithm cPoW

Input:  the new block header $bh:=(ph,mt,sl)$, the target value tv, the voting weight function $\mathcal{F}$, the key binding identification lid, and the ring member set R Output:  weight w and proof info    1:parse $w:=0$, $info:=⌀$, the current timestamp is $tm$;    2:while  $tm<sl+q+\Delta$ do    3:  if find ne to make $\mathcal{H}(tm,ph,ne,mt,\mathcal{H}(lid\left|\right|R\left)\right)<tv$ then    4:    $w=w+\mathcal{F}\left(tv\right)$, $info=info\cup (ph,tm,ne,mt,tv,lid,R)$;    5:return$(w,info)$;
