An electronic sports betting system and method includes a betting extension in a browser of a client computer, communicating with an odds modeling engine of a betting platform. The betting platform defines a tournament structure of an electronic sports tournament comprising teams performing the electronic sports tournament on a computer network, and generates a module for each of a number of distinct parts of the tournament structure. The betting platform successively simulates each module to generate a model for the electronic sports tournament, the model representing possible actions and outcomes by the teams performing each of a number of distinct parts of the tournament structure. The betting platform then models team behavior of each of the teams based on the model, and generates odds of the possible actions and outcomes of the electronic sports tournament based on the successive simulation of each module.

A system, method, device, and platform for performing a gaming utilizing blockchain. A player profile is created in response to information received from a player. Gaming information is received from the player associated with the one or more games. Selections are assigned to the player for the one or more games utilizing player profile and the gaming information. Winners and a host with each of the one or more games of the one or more games are compensated once the one or more games are completed. The player profile, the gaming information, the selections, and the winners are documented utilizing the blockchain.

The present invention provides an improved system and method for using cryptography to secure computer-implemented choice mechanisms. In several preferred embodiments, a process is provided for securing participants' submissions while simultaneously providing the capability of validating their submissions. This is referred to as a random permutation. In several other preferred embodiments, a process is provided for securing participants' advance instructions while simultaneously providing the capability of validating their advance instructions. This is referred to as a secure advance instruction. Applications include voting mechanisms, school choice mechanisms, and auction mechanisms.

A system for presenting a skill-based game, the system includes at least one server to serve a set of matchups of participants of an event, to a plurality of presentation devices, the plurality of presentation devices displaying the set of matchups on a display; to receive over the wide area network data from the presentation devices characterizing a set of user selected winners of the matchups made by the users; update the event data pertinent to participants in the actual events; using the updated data to calculate and assign payoffs to the users based on fixed payoff odds. A related computer-implemented method provides participant matchups to an operator organizing such a skill-based game.
