A system and method that relies upon smart contracts to facilitate cryptocurrency trades through a plurality of different exchanges. The system and method preferably operate on the blockchain.

Aspects of the disclosure relate to storing sensitive information. A computing platform may split a signature key into shares, which may be used to regenerate the signature key. The computing platform may encrypt these shares using corresponding SEKs, and may subsequently encrypt the SEKs using corresponding operator keys. The computing platform may distribute the operator keys to user devices via corresponding HSMs. The computing platform may store the encrypted shares, encrypted SEKs, and identifiers of the user devices. The computing platform may receive requests for the encrypted SEKs from the user devices, and may send the respective encrypted SEKs accordingly. The user devices may return, to the computing platform, corresponding decrypted SEKs. The computing platform may use the SEKs to decrypt the encrypted shares, which may then be used to reconstruct the signature key.

Apparatus and methods are provided for the approximation of two bones, the apparatus including a first anchor that is rotationally driven into a first bone by a second bone anchor, which receives driving torque from a driver tool. After the first anchor is secured in the first bone, the second anchor is disengaged from the first anchor but remains connected to the first anchor by a flexible link of a designed length. The second bone anchor is secured in the second bone and has provisions to be lengthened or shortened to adjust the overall length of the implant, thereby adjusting the approximation between the two bones.

A wallet device comprising, a central control server device to accept a trading request data from external, a transaction manage device, a hot wallet server device, a cold wallet server device and a remote signature device, the transaction manager device comprising unit to create/output transaction data conforming to the bitcoin network in the internet, is located in-between the central server device creating internal format model transaction and other devices group of hot wallet server device, cold wallet server device and the remote signature device performing to sign multi-signatures, providing more secured wallet device for cryptocurrency.

In general terms this invention provides embodiment of systems that permit better usage of consumer generated data that permit the consumer methods to monetize the information and maintain control over the data at the time of its creation and at later times. Certain embodiments comprise a user whose interaction can cause a provider to create data regarding the interaction. The user can authenticate the data using encryption aspects and permit the user to self-publish data. The self-publishing can occur in a manner that only requires direct trust of the technology provider regarding the data validity. The invention may incorporate an Ethereum network. Embodiments of the system may verify, exchange, encrypt and decrypt data allowing purchasers to purchase the data or certain portions of it.

Example methods, apparatuses, and systems are presented that allows a consumer to conduct a purchase backed by a volatile currency that is not recognized by a merchant as a valid form of payment, such as a cryptocurrency. A third-party payment system is configured to issue a secure, reliable token to replace a reserved amount of volatile currency that represents a reliable amount of currency that is recognized by the merchant as a valid form of payment. The third-party payment platform may issue the reliable amount of currency in the reliable token based on one or more risk factors associated with the volatile currency. After purchase, the third-party payment platform may perform a consumer settlement process at a later time, including performing a cryptocurrency blockchain verification process that typically takes at least several minutes and would be impractical to perform at the point of sale.

One or more techniques and/or systems are disclosed for mitigating distribution costs for travel providers while allowing customers to buy, sell, and view available travel reservations on a de-centralized GDS/PMS/OTA network driven by Blockchain technology. Further, the system can allow for customer-to-customer sales of travel reservations using the de-centralized GDS/PMS/OTA solution.

Disclosed embodiments may include systems and methods for the creation of self-executing smart contract computer programs (Smart Contracts) recorded on one or more blockchains as on chain contracts comprising machine extracted terms from non-blockchain recorded (off chain) digital contracts. Disclosed systems include means of conversion of fiat currencies to cryptographically generated and unique tokens (crypto-tokens) at a pre-set market exchange rate that does not fluctuate after the initial exchange and until directly exchanged back to the original fiat currency. Disclosed systems facilitate automated digital performance of the payment terms of off-chain contracts via on-chain smart contracts and crypto-tokens. Upon the performance of an on-chain self executing smart contract, the system will automatically release crypto-tokens or other consideration that is either held in escrow or held by an interested party. In case of a contract dispute, the system will issue a judgment using electronic data, pre-defined rules and machine logic.

A blockchain asset that is transferred from a second blockchain member is received at a first blockchain member in response to an asset transfer request for transferring an asset between a payer and a payee, where the first blockchain member and the second blockchain member associated with a blockchain. In response to receiving the blockchain asset, an off-chain asset transfer-out operation for the payee is performed by the first blockchain member. If the off-chain asset transfer-out operation fails, a transaction reversal application for an asset transfer transaction corresponding to the asset transfer request is written into the blockchain by the first blockchain member. In response to writing the transaction reversal application, an asset clearing with the second blockchain member for an off-chain asset corresponding to the off-chain asset transfer-out operation is performed by the first blockchain member.

An asset transfer request to transfer an asset to a blockchain member associated with a blockchain is detected, where the asset is of a specified asset type and is issued by a specified anchor in the blockchain. Whether there is a maximum trusted asset limit configured by the blockchain member for the specified anchor and that corresponds to the specified asset type is determined. If it is determined that the maximum trusted asset limit is not configured, application of the asset transfer request to the asset is prohibited. However, if it is determined that the maximum trusted asset limit is configured, whether the maximum trusted asset limit is exceeded is determined. If it is determined that the maximum trusted asset limit is not exceeded, the asset transfer request is applied to the asset.
