A device may obtain digital signature information relating to a quantity of a type of cryptocurrency, and receive transaction data relating to a credit account, associated with a user, after obtaining the digital signature information. The transaction data may include information identifying a transaction amount. The device may determine, after receiving the transaction data, an amount, of the type of cryptocurrency, that satisfies the transaction amount, perform, using the digital signature information, an action to conduct a sale of a portion of the quantity of the type of cryptocurrency based on determining the amount, and cause proceeds from the sale to be transferred to the credit account as payment for the transaction amount.

An automated computerized trading system is provided wherein a decentralized autonomous organization (DAO) includes a wallet having blockchain-based, smart-contract controlled cryptoassets associated with a commodity. The DAO receives data infeed from Application Programming Interfaces (APIs) from the blockchain to obtain cryptoasset price data and from an exchange to obtain commodity price data. The DAO stores commodity price and cryptoasset price spread targets and automatically initiates trading activity based on the price spread targets. A governance smart contract automatically distributes governance cryptoassets to public wallets that have contributed the crytpoassets to the DAO wallet.

Systems and methods for offering and purchasing tokenized securities on a blockchain platform meeting current and future federal, state, and offering and holding entity rules and regulations. Tokenized securities purchased during or after the tokenized securities offering are tradable on a secondary market. The server computer of the tokenized securities provides an automated transfer capability for tokenized securities holders.

A mechanism for verifying digital information provenance and attestation using blockchain distributed ledger technology which reveals unauthorized tampering with credentialed information. Content modifications are detectable leveraging only local edge validation supported by the normative Bitcoin Core cryptographic libraries or equivalent blockchain implementations. The invention prevents unauthorized access, unregulated copy distribution, and orphaned ownership lacking issuer provenance and attestation. The preferred embodiment provides tamper detectable digital content containers supporting credentialing, remote administration, localized validation, distributed access control, and processing instruction signaling. Intermediary third-party services are not required to verify provenance and issuer attestation. Blockchain integrated cryptographic information containers and administrative transactions immutably record the binding between participating parties (e.g., issuer, administrator, requestor) and associated digital assets (e.g., insurance card, medical records, driver's license, passport, biometric, business contract, software application files, data).

Systems and methods to track display of a digital content item and distribute rewards based on the display are disclosed. Exemplary implementations may receive a display request identifying the digital content item, effectuate display of the digital content item on a wearable device, receive display information associated with the display of the digital content item on the wearable device, determine and distribute rewards to the user in accordance with the display information, and/or perform other operations.

Systems and methods are provided for minting payment tokens to conduct transactions within a blockchain-based supply chain payment network. The payment tokens can be pegged to fiat currency or digital currency. The payment tokens can be minted by a computing system that is a node in the blockchain-based supply chain payment network. A number of payment tokens to be provided to a network participant as payment can be determined. The network participant can be a supplier associated with the blockchain-based supply chain payment network. The number of payment tokens can be provided for deposit in a digital wallet associated with the network participant as payment. The cryptocurrency tokens can be redeemed as fiat or digital currency.

Disclosed herein are systems to effectuate cost-sharing communities on one or more forms of computer readable media utilizing sharing protocols and a set of rules-based, configurable set of methods, and processes over which the specific transactions can be modeled and implemented.

A solution for controlling access to a resource such as a digital wallet implemented using a blockchain. Use of the invention during set-up of the wallet can enable subsequent operations to be handled in a secure manner over an insecure channel. An example method comprises splitting a verification element into multiple shares; determining a common secret at multiple nodes in a network; and using the common secret to transmit a share of the verification element between nodes. The shares can be split such that no share is sufficient to determine the verification element and can be stored at separate locations. Upon share unavailability, the share can be retrieved a location accessibility. For safe transmission of the share(s), the common secret is generated at two different nodes independently and used to generate an encryption key for encrypting at least one share of the verification element to be transmitted securely.

Method for the secure execution of programs (smart contracts) implemented between a first wallet node (WN) (WN1) and a second wallet node (WN2), at least the second WN being implemented in an enclave of a processor, and the WNs being capable of executing programs designated in the messages that reach them, the method comprising the following steps: a) sending by WN1 to WN2 of a pre-message; b1) in response to this pre-message, execution in the enclave of a first program (WNRoT); b2) generation by the enclave of a certificate of authenticity of said first program and of the integrity of its execution; b3) sending said certificate to WN1; c) verification by WN1 of said certificate; d) in the event of successful verification, sending by WN1 to WN2 of a message intended to trigger the execution of a given program in WN2, and e) execution of said program in WN2.

A method for distributed-ledger based intercompany netting may include: receiving, from a first entity within an organization, a deposit of a first amount of funds to a first account; tokenizing the first amount of funds and writing the first amount of funds to a first token wallet for the first entity on a distributed ledger; receiving, from a second entity within an organization, a deposit of a second amount of funds to a second account; tokenizing the second amount of funds and writing the second amount of funds to a second token wallet for the second entity on the distributed ledger; and executing a transaction involving a transfer of a transaction amount from the first entity to the second entity by deducting the transaction amount from a token balance in the first wallet and adding the transaction amount to a token balance in the second wallet.
