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.

The creation of a private sub-blockchain from a main blockchain is disclosed including receiving a request including a trust requirement and an agility requirement, receiving monitoring data from at least one of a plurality of validator nodes of the main blockchain, the monitoring data generated by monitoring the execution of transactions and the exchange of consensus messages by one or more of the plurality of validator nodes, determining a minimum number of validator nodes required to meet the trust requirement, identifying a subset of the plurality of validator nodes of the main blockchain that meets the agility requirement based on the received monitoring data, the subset containing at least the determined minimum number of validator nodes required to meet the trust requirement, and creating a private sub-blockchain of the main blockchain, the private sub-blockchain including the identified subset of the plurality of validator nodes of the main blockchain.

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 computer-implemented method for improving the security of a data record distribution process using a blockchain having a group of input nodes and a group of output nodes, each group having a private-public key pair, but wherein the nodes only have a key share of their respective private key and no node has a full private key. Using threshold signature scheme, secret share joining, and stealth addresses, data records from the input nodes are pooled at a stealth address determined through collaborative action of the input nodes, requiring cooperative determination of their public key, a shared secret, and the stealth address. The public key is copied into the transaction. The output nodes locate the transaction and extract the public key, collaboratively verify its authenticity, and collaboratively determine the shared secret. Having done so, the output nodes may, collectively, sign a second transaction for distributing data records from the stealth address to the output addresses. The invention may be used in conjunction with the Bitcoin blockchain, for example, or another blockchain implementation.

Disclosed herein is digital object generator that makes uses a one-way function to generate unique digital objects based on the user specific input. Features of the input are first extracted via a few-shot convolutional neural network model, then evaluated weight and integrated fit. The resulting digital object includes a user decipherable output such as a visual representation, an audio representation, or a multimedia representation that includes recognizable elements from the user specific input.

Systems, methods and/or computer program products issuing and transferring presentation rights between users during digital events using NFTs and incentivizing audiences to remain active attendees of digital event as new presenters take over the presentation. Value exchanged for obtaining NFTs representing presentation rights can correlate to a speaker score which is calculated using audience metrics collected by the platform. Presenters with higher presenter scores and larger or more active audiences can result in higher valuations, increasing the value of the NFT being purchased. Exchanges of value and NFTs are executed using non-custodial wallets and/or smart contracts. The value exchanged for the NFT can be split between original presenters' wallets and wallets of the audience members in pre-determined ratios. Funds provided to audience members' wallets during digital events can be locked or restricted for pre-set minimum amounts of time, incentivizing audience members to remain attentive to the next presenter.

A method to facilitate processing of recyclable items. Accordingly, the method may include capturing, using at least one sensory device, sensory data associated with at least one recyclable item. Further, the method may include receiving, from the at least one sensory device, event data associated with a recycling process. Further, the at least one sensory device may include at least one of a hyperspectral camera, a spectroscopic scanner and a colored filter scanner configured for capturing at least one image of at least one recyclable item undergoing the recycling process. Further, the method may include analyzing, using a processing device, the event data using at least one image processing model. Further, the method may include issuing, using the processing device, the predetermined amount of crypto tokens to a second crypto account associated with a second user device based on the generating and the sensory data.

Disclosed are various embodiments directed towards devices, systems, and methods involving the use of cryptocurrency in player tracking and reward systems. A player may deposit cryptocurrency into a player account for the purpose of funding casino play. The player may also withdraw funds from the player account in the form of cryptocurrency. The player may also redeem player loyalty points for cryptocurrency accepted by various merchants. The casino's cryptocurrency may be a wrapped version of a public cryptocurrency and may mimic a public stablecoin. The cryptocurrency held by the casino may be maintained on an enterprise blockchain or in a distributed ledger system in which multiple casinos participate to provide an efficient common private cryptocurrency in any of the participating casinos with a minimal cost per transaction.

Provided are private networks for peer-to-peer financial transactions and value transfers comprising, for each peer-to-peer financial transaction, an electronic document comprising at least the core terms of the peer-to-peer financial transactions; a unique identifier for that transaction; the identities of each party involved in the transaction; an authorization approval section for the document that requires use of the signing key unique to a party authorizing the transaction; and a timestamp corresponding to the time a party authorized the transaction.

Systems and methods for facilitating a transaction between a first entity and a second entity using a digital currency are described. In some aspects, a computing node participates in a private distributed ledger for a financial institution and stores one or more transaction blocks representing transactions in a digital currency. The digital currency is issued by the financial institution and is fixed with respect to a fiat currency. The computing node is configured to receive a transaction for transferring an amount of digital currency from a first entity to a second entity, generate a new transaction block representing the transaction, transmit the new transaction block to other computing nodes participating in the private distributed ledger, receive an indication of validity of the new transaction block, and insert the new transaction block into the private distributed ledger.
