A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. The cryptographic token is written to a blockchain using a smart contract that is configured to enable a transaction associated with the token in response to two or more of: a signature by the encryption chip, a signature by the owner of the diamond asset, and a validation of a visual layout of the diamond asset.

Methods and systems are provided for crowdsourced funding via a blockchain system. A token contract, associated with a token issuer, is generated on a blockchain system. Tokens are issued to a plurality of token holders. Each of the plurality of token holders is allowed access to a feedback mechanism associated with the token issuer. A performance of the token issuer in an associated field is monitored to provide at least one performance metric. A dividend is paid to each token holder proportional to a number of tokens held by the token holder after a predetermined amount of time based on the at least one performance metric.

A system and method is disclosed for assuring that networked communications between parties playing a game on a network (e.g., the Internet) are not tampered with by either of the parties for illicitly gaining an advantage over the other party. An initial sequence of tokens (e.g., card representations) for playing the game are doubly encrypted using an encryption key from each of the parties. Accordingly, during play of the game neither party can modify the initial sequence of game tokens during the game. At termination of the game, at least one of the parties can fully decrypt the initial sequence of tokens, and thereby, if desired, compare the played token sequence with the corresponding the initial token sequence.

Embodiments of systems and methods for the aggregation, analysis, display and monetization of pricing data for commodities in general, and which may be particularly useful applied to vehicles are disclosed. Specifically, in certain embodiments, historical transaction data associated with a particular vehicle configuration may be obtained and processed to determine pricing data associated with the vehicle configuration. The historical transaction data or determined pricing data may then be presented in an intuitive manner.

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.

Different aspects of the invention implement an enhanced DLT system, and corresponding method, that allows the peer-to-peer transmission of huge amounts of data packets of content between users, and to be stored in the DLT network, in a secure, trustworthy and efficient manner. By allowing the interface between any type of existing layer 1 DLT network, it does not require the complex, slow, costly and highly risk process involved in the generation of a new layer 1 DLT network. It opens up the range of possible applications of the DLT network to applications in Big Data, IOT, Web 3, MMOG, or any other environment that needs the trust provided by the immutability of data stored in the DLT network.
