A system and method for digital smart wallet communications that operates by managing separately-owned, private blockchains to reduce processing times, eliminate proof of work burdens, and retain blockchain immutable security while allowing protection of confidential information contained on each blockchain. The system and method may further comprise auditability of blockchains, and may be operated on an integrated communications platform that allows seamless interoperability of communication devices across multiple modes of communication, and automates digital smart wallet transactions.

A system for transacting in an environment with intermittent connectivity via a network backbone to a blockchain. A merchant device transmits a set of credentials for an ad hoc network to a buyer device and establishes a private peer-to-peer ad hoc network connection with the buyer device. It then conducts a transaction with the buyer device via the private peer-to-peer ad hoc network. If no network connection is available to a transaction blockchain, the merchant device stores a record of the transaction until such network becomes available and later sends the record of the transaction to the transaction blockchain.

According to an embodiment, a method for automatically providing a cryptocurrency to a recommender using social networking service (SNS) propagation comprises a recommending step in which a blockchain membership node of a member having membership in a proof-of-expansion (PoX) blockchain platform server recommends an identity (ID) of an SNS friend of the member to the PoX blockchain platform server, a registering step in which the PoX blockchain platform server newly registers the ID of the SNS friend as a blockchain membership node, and a reward rate determining step in which the PoX blockchain platform server determines a reward rate for each blockchain member in association with the number of SNS friend IDs that the blockchain member recommends.

The disclosed embodiments provide a distributed transaction system including a group of validator nodes that are known to each other in a network but are indistinguishable to other network nodes. The validator nodes form a Committee including a Leader node and one or more Associate nodes. The Committee may be dynamically changed, such that new network nodes may be added to the Committee or may replace existing validator nodes. The Associate nodes also may coordinate with each other to select a new Leader node. The disclosed embodiments reduce the distributed system's reliance on the stability of any particular node(s) in the network, as the validator nodes in the Committee may be changed at a sufficient frequency to remove unreliable, unavailable, or otherwise untrusted nodes. Further, the disclosed embodiments provide a scheme that helps ensure the Leader node, as well as the other Committee members, functions properly.

A system and method receive a plurality of crypto profiles that include customizable rules for different cryptocurrencies and operating state information that initialize containerized lending applications. The system and method ink the crypto profiles to a matching engine before the containerized lending applications and the matching engine match a plurality of borrower requests for a debt or an equity denominated in a cryptocurrency to lending requests. The system and method collect cryptocurrency payments in response to the use of the debt or the equity by the borrower. Each containerized lending application include executable software, runtime code, system tools, and system libraries that enable the containerized applications to run on two or more computing environments without modification.

Examples relate to multiple microprocessor architecture for cold storage of digital currency. A hardware wallet may include a first microprocessor configured to establish a secure connection with a mobile device connected to a network having access to a blockchain and a second microprocessor configured to generate a private key and a public key for communication of transaction data onto the blockchain. The second microprocessor may initially use a hash function and the private key to encrypt the transaction data and produce a digital signature independent from the first microprocessor and subsequently provide the digital signature and the public key to the first microprocessor for communication onto the blockchain via the secure wireless connection with the mobile device. The second microprocessor may also encrypt and store the private key securely within the wallet's memory such that the private key is readable only by the second microprocessor.

Extracting the beneficial elements from Bitcoin, discarding the negative aspects of this ground breaking currency, BitMint*LeVeL replaces the single public/private key formula with coin-owner selected surprise formulas to shift security responsibility to the trader, and create a quantum safe currency with robust anonymity while maintaining a smooth extension of legacy currency, and relying on a community of mints (an InterMint) to keep the community in control.

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 system and method for preventing the double-spending of digital currency that transfers between multiple distributed ledger technology (DLT) networks. The system and method includes receiving an authorization to monitor transaction requests associated with a first DLT network. The system and method includes detecting a transaction request to transfer the first digital currency from the first DLT network to the second DLT network. The first digital currency is created on the first DLT network based on a unit of fiat currency. The system and method include transferring, responsive to detecting the transaction request, the first digital currency from the first DLT network to the second DLT network.

The disclosed computer-implemented method for hindering malicious computing actions may include (i) identifying an attempt by an agent to perform an action on a computing resource that is vulnerable to attempted actions performed by unauthorized agents, (ii) requesting from the agent, in response to identifying the attempt to perform the action on the computing resource, a payment to an owner of the computing resource equal to a monetary value assigned to performing the action on the computing resource, (iii) receiving, by the owner of the computing resource, the payment of the monetary value from the agent, and (iv) allowing, in response to receiving the payment of the monetary value from the agent, the attempt by the agent to perform the action on the computing resource. Various other methods, systems, and computer-readable media are also disclosed.
