testing:

I think this might be a hex dealio, so I did some stuffs in node based on what the googles told me to do to parse

> var thing = '0x2BFC8E2B3561C04FBBC73FA43D5D96540D0AA008B30924CE47DA0EC67530D3'
undefined
> var bytestring = Number(thing).toString(10);
undefined
> bytestring
'7.771749672767704e+73'
> parseInt(bytestring, 2).toString(16);
'NaN'
> parseInt(bytestring, 2)
NaN
> bytestring
'7.771749672767704e+73'
> Number(bytestring)
7.771749672767704e+73
> parseInt(Number(bytestring), 2)
NaN
> var numbs = Number(bytestring)
undefined
> typeof(numbs)
'number'
