This service allows you to obtain the prizes of the draws of the https://lotodobicho.com application based on the HASH of the Bitcoin immediately after the date and time established for a draw.

For this purpose, the 128-bit Hash obtained in the previous draw (prevHash) is used. (In the first draw use '' as prevHash).

For example this 128 bits hash belong previous draw: d57cbd9ef56e9bc773c9ad93a2131d2e3ab64acf54ed1466da21efdd145b243
