The present disclosure describes transaction-enabling systems and methods. A system can include a controller and a fleet of machines, each having at least one of a compute task requirement, a networking task requirement, and an energy consumption task requirement. The controller may include a resource requirement circuit to determine an amount of a resource for each of the machines to service the task requirement for each machine, a forward resource market circuit to access a forward resource market, and a resource distribution circuit to execute an aggregated transaction of the resource on the forward resource market.

A system may receive a request for user data associated with a user account, transmit the user data in response to the request, and receive an authorization request for a transaction from a merchant device. The authorization request may include transaction data and an item identifier. The system may also approve the transaction in response to a user account having sufficient funds available and store the transaction data and the item identifier in association with the user account.

The technology teaches a distributed gaming system, comprising a server-side node configured to administer transactions for a gambling casino, selling and redeeming chips using a private database, and recording transactions on a distributed ledger using crypto-tokens for a house account, with a token vault wallet that has a unique identifier and private key to track transactions. Customer wallets, intermediary accounts and one-way redemption wallets track transactions on the distributed ledger. Client-side nodes accept token purchase messages and transfer tokens in the ledger and record in the database, accept token-to-chip messages from an intermediary account and transfer tokens on the ledger to the redemption wallet to extinguish and record the exchange, accept chip-to-token messages from an intermediary account and transfer tokens from the vault to the customer account and record the exchange, and accept token-to-fiat messages from an intermediary account and transfer tokens to extinguish, and record the exchange.

Methods, systems, and apparatuses for block chain security schemes for electronic cash tokens are described herein.

A secure method for exchanging entities via a blockchain is presented. The method comprises receiving, from a user over a communications network, an invitation to perform an exchange of entities; generating a redeem script comprising metadata; hashing the redeem script to generate a redeem script hash; sending the first script and the first script hash on a distributed hash table (DHT); and generating an invitation transaction comprising an output associated with an encrypted digital asset, and a hash of a script comprising an indication of entities to be exchanged, conditions for the exchange, and a public cryptographic key associated with the user.

Provided herein is a computer-implemented method, a system, and a non-transitory computer-readable storage medium. The system may be implemented using a blockchain network. The computer-implemented method includes: i) attaching a digital asset of a first entity to an exchange platform; ii) computing a first shared key associated with the digital asset using a key of the first entity and a first key of the exchange platform; iii) generating and broadcasting a first blockchain transaction to a blockchain network; and iv) initiating, by the first entity, transfer of ownership of the digital asset from a first entity to a second entity; v) computing a second key and a second shared key; vi) replacing the first key associated with the exchange platform with the second key associated with the exchange platform; and vii) detaching, by the second entity, the deposit from the exchange platform using the second shared key.

Methods and devices for propagating transactions in a network of nodes, each node having one or more connections to other nodes. The method includes receiving a plurality of incoming transactions over a time period; combining the plurality of incoming transactions using network coding to generate a composite message; sending the composite message to one or more nodes in the network; and determining an adjusted time period based on an equilibrium constant parameter and a count of transactions in the plurality of incoming transactions received over the time period.

There may be provided a computer-implemented method. It may be implemented using a blockchain such as, for example, the Bitcoin blockchain. The computer-implemented method includes: i) joining a congress by transferring, by a node operating in a proof-of-work blockchain network, one or more digital assets to a congress pool having one or more other digital assets associated with other members of a congress; ii) detecting, by the node, a special transaction of digital assets on the proof-of-work blockchain network to an address associated with the congress pool, the special transaction satisfying determined criteria; and iii) minting, by the node, one or more digital assets on a proof-of-stake blockchain network in response to detecting the special transaction.

A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions (involving the transformation, conversion or transfer of information or value) are processed concurrently in a scalable, reliable, secure and efficient manner. In one embodiment, the computing network fabric or “core” is configured to support a distributed blockchain network that organizes data in a manner that allows communication, processing and storage of blocks of the chain to be performed concurrently, with little synchronization, at very high performance and low latency, even when the transactions themselves originate from distant sources. This data organization relies on segmenting a transaction space within autonomous but cooperating computing nodes that are configured as a processing mesh. Each computing node typically is functionally-equivalent to all other nodes in the core. The nodes operate on blocks independently from one another while still maintaining a consistent and logically-complete view of the blockchain as a whole. According to another feature, secure transaction processing is facilitated by storing cryptographic key materials in secure and trusted computing environments associated with the computing nodes to facilitate construction of trust chains for transaction requests and their associated responses.

Systems and methods for providing risk determination in a crypto currency transaction include receiving, through a network via a broadcast by a first payer device, a first crypto currency transaction that includes a first payee public address. A first request for a determination of risk associated with the first crypto currency transaction is then identified in the first crypto currency transaction, with the first request including risk criteria. A first payee involved in the first crypto currency transaction is then identified using the first payee public address, and first payee risk information is accessed via at least one external risk information database based on the identification of the first payee. If it is determined that the first payee risk information satisfies the at least one risk criteria in the first request, the first crypto currency transaction is provided for addition to a block in a crypto currency public ledger.
