A system that can transfer tokens of multiple classes from issuers to recipients is disclosed. The system generates class-specific token specification that include parameters that must be satisfied for the first user to acquire, from another user of the system, any token that is created according to the class-specific token specification. The system will save the records for each of the class-specific token specifications to a digital ledger that is accessible to users of the system. When a transfer request is received for a particular token, the system will execute a smart contract by (a) accessing the digital ledger to verify that a class-specific token specification exists which corresponds to the class of the particular token, and (b) in response to the verifying write, to the digital ledger, a first ledger entry that includes a record indicating that the amount of the particular token has been transferred to the recipient.

Provided is a process for tracking trees. The process of tracking trees may include one or more of generating a listing of trees, generating digital tokens representing the trees, or performing one or more operations associated with the trees using the digital tokens (e.g., creating a market place for trading digital tokens, trading digital tokens, or computing carbon credits associated with a tree).

Systems and methods for administering fractionalized interests in assets in a decentralized network are described. In some embodiments, a system may be configured to receive a first plurality of fungible tokens representing fractionalized interests in a first asset and a second plurality of fungible tokens representing fractionalized interests in a second asset. The system may be configured to receive a message from a user. In response to receiving the message from the user, the system may be configured to transfer to the user a randomized set of fungible tokens to the user, the randomized set comprising one or more of the fungible tokens of both the first plurality of fungible tokens and the second plurality of fungible tokens.

A custom cryptographic token and smart contract that is configured to exist in one of two groups and is issued by the same bank or depository institution that also collects corresponding fiat currency deposits. The two groups are a circulation group and a non-circulation group. The non-circulation group is not associated with any given user, but rather an issuing entity. Custom cryptographic tokens residing in the circulation group are associated with a user and are traded according to smart contract protocol.

A method for mining a block in a decentralized blockchain consensus network (DBCN) includes sending, by a mining computing entity (MCE), a signing request for mining a new block of a blockchain to a trusted execution environment computing entity (TEE-CE), the signing request including block information, the block information including block height information, and comparing, by the TEE-CE, the block height information of the signing request with block height information from a last signing request and providing a matching, when the difference between the block height information of the signing request and the block height information from the last signing request satisfies a defined value. The method further comprises, upon providing the matching, signing, by the TEE-CE, the new block based on the block information, and providing, by the MCE, the new signed block to the DBCN.

Systems and methods for a comprehensive online media marketplace are provided that increase the efficiency of media sharing between consumers and content producers. In one embodiment, a method comprising streaming media content from a streaming platform to a consumer device, creating a stream report for the media content based on a smart contract associated with the media content, wherein the smart contract identifies a media content producer of the media content, recording the stream report on a blockchain, issuing tokens based on a pre-determined rate of inflation, and distributing a portion of the tokens to the media content producer based on the stream report.

The present disclosure provides NIR- and SWIR-active small molecule polymethine dyes with improved properties for use in optical imaging, photothermal therapy, and photodynamic therapy.

A computer-implemented method includes: determining assets held by a remitter, the assets to be spent in a remittance transaction between the remitter and one or more payees, in which each asset corresponds to a respective asset identifier, a respective asset amount, and a respective asset commitment value; determining a remitter pseudo public key and a remitter pseudo private key; determining a cover party pseudo public key, in which the cover party pseudo public key is obtained based on asset commitment values of assets held by the cover party; and generating a linkable ring signature for the remittance transaction.

Disclosed are various embodiments for blockchain-based product configuration and referral. An originator may interact with a product configuration service to generate a product combination, which may include a particular combination and arrangement of physical or virtual items. A blockchain data object may be generated that is unique to the product configuration. The blockchain data object may be inserted into a blockchain using a blockchain network service such that, when the product configuration is subsequently accessed or consumed by another user account, a predetermined task is performed in association with a user account of the originator.

Systems, apparatuses and methods may provide for technology for establishing and managing trusted payment tokens. The technology may include a database of trusted payment tokens and identifiers. The technology may receive a request for a trusted payment token, generate a trusted payment token based on parameters received, and return a trusted payment token identifier. The technology may further receive a trusted payment token identifier, verify the token based on parameters received, and return a token approval notice, authorizing a cash payment or deposit according to the token amount.
