A digital platform enables 3D printing where the designs are protected from piracy/redistribution. A single board computer (SBC) communicates with a first server and a second server. The SBC requests a unique hardware ID from the first server, which assigns and sends the ID to the SBC. The SBC submits the ID and a secret key to the second server to request registration of a user and a printer, and the second server sends private certs, a client ID, and a unique public identifier to the SBC. The second server also receives and stores 3D print designs through a designer portal, and on-demand displays the designs in a GUI screen. The SBC user may purchase a 3D print design, and the second server, in response, sends an access token to the SBC. The SBC redeems the access token for a selected 3D print, and the second server adjusts gcode for the selected 3D design for the particular printer, and streams the adjusted gcode to the printer through the SBC, thereby protecting the code from unauthorized user/replication.

The invention provides a smart cryptocurrency wallet. Embodiments of the invention provide a blockchain-implemented system and corresponding method for the secure, cryptographically enforced execution of a task. The invention may be implemented in conjunction with the Bitcoin blockchain, a variation thereof or an alternative blockchain platform. The invention provides an enhanced digital wallet which is capable of performing extended functionality beyond that of known cryptocurrency wallets. A system in accordance with the invention comprises a digital wallet; and a process execution component, e.g. an interpreter, embedded within, associated with, or arranged to interact with the digital wallet. The interpreter is arranged to execute or initiate at least one process in response to at least one trigger associated with or provided in a script for a blockchain transaction. The trigger may comprise one or more codes and/or parameters. The trigger may be codified within metadata in a locking script, and be provided to the wallets interpreter upon spending of the transaction output. The interpreter may be installed as a plug in or extension to the wallet.

The usage of money has been always abused for financial crime. The invention of cryptocurrency on Blockchain did not change that since the ownership essentially remained anonymous. The present invention deals with the programmatic parameterization of cryptocurrency Smart Contracts to include the binding between the user's cryptocurrency transaction and user's Identity, thus creating permissioned crypto-token transfer. Such binding has advantageous properties as being resilient to any form of financial crime, preventing cryptocurrency theft, and precluding bad actors from using this cryptocurrency. The system for Identity-Bound Cryptocurrency Transfer (IBCT) will include IBCT Blockchain Smart Contract, IBCT Blockchain Oracle Smart Contract, and off-chain Identification-as-a-Service for the IBCT owner using dedicated CryptoWallet for executing IBCT Smart Contract. The Financial crime-preventive usage of cryptocurrency is achieved through user-opted, while pseudonymous, binding of the user's Blockchain public address with the user's identity. This Financial crime-preventive usage of cryptocurrency is facilitated via a specialized crypto wallet.

A method to provide direct incentivization for data accuracy for distributed ledger-based reconciliation processes. The invention describes a method to quantify and potentially reward consensus between different parties storing data on a distributed ledger. The implementation of distributed ledgers enables a new class of business methods that enable and incentivize data accuracy at granular levels via distributed consensus.

Confidence coin, in short Coco, is an upgrade to the cryptocurrency technology, it replaces P2P network with Royal Network and using a special block encoding that together allows blocks as big as Gigabytes of data. It offers micro and macro transactions via Decentralized Trusted Parties. It also increases users privacy and helps government regulators to protect the system from illegal trades and fraudulent activities. Coco upgrades smart contracts to Automated Smart Contracts that allow automatic payments. And it has a leadership organization, founded by Coco system itself with a single purpose of making Coco great.

Systems and methods for payment processing using cryptocurrency assets.

System and method for synchronizing blockchain nodes by using snapshots.

A method of increasing security of digital assets stored in an isolated device by associating the isolated device with a plurality of accounts of the user each configured to store a limited value of digital assets, each of the plurality of accounts is assigned an asymmetric cryptographic key pair (comprising a unique private key encrypting the respective account and a corresponding public key identifying the respective account), transmitting, via a unidirectional secure channel, the public key assigned to each of the plurality of accounts to one or more computing nodes connected to a network community regulating the digital assets and transferring a value of the digital assets by transmitting, to one or more of the computing nodes, the private key of one or more of the plurality of accounts cumulatively storing the transferred value thus releasing the limited value stored in the respective account(s).

A system for operating a payment network with a blockchain-based ledger may prepare a request to complete a transaction from an account associated with a payer digital wallet for entry on the blockchain. The request may include an amount and payee address associated with a payee digital wallet. The system may also send the request to the blockchain using a blockchain interface. The system may approve or decline the request. The system may further adjust a balance of the payer a balance of the payee to reflect approval of the request. The adjustment may include writing the transaction to the blockchain.

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.
