Systems and methods for enabling the secure use of cryptocurrencies (such as but not limited to Bitcoin, Ethereum, or Litecoin) in prize funds or gift cards that accept purchases or wagers in fiat currencies and payout in cryptocurrency. The prize funds can be associated with lotteries, charitable gaming, or casino environments with the inherent volatility of cryptocurrencies optionally mitigated and cryptocurrency payouts enabled for consumers or players without prior digital wallets as well as consumers or players with preexisting digital wallets.

The present invention is systems and methods of self-administering protocols on a blockchain platform. A system and method of self-administered protocols on a blockchain platform, comprising: self-administering one or more of the following actions: consensus, governance, self-forking, view change or finality of transactions on the blockchain platform; operating without a hierarchical structure to make decisions; validating the decision to avoid rogue decisions or attacks; setting of a time period to lapse to finalize the decision; allowing the set time period to lapse; finalizing the decision by saving the state on the blockchain platform. Self-administering also includes the capability of the blockchain platform to prune the state of the smart contracts and the global state of the blockchain platform.

Techniques are disclosed which include receiving, by a central entity computer, a request for digital currency. The request includes a serial number and a denomination of a physical currency. The central entity computer generates the digital currency for the denomination and linked to the serial number. The generating includes recording the digital currency on a blockchain. The central entity computer transmits a notification of the generation of the digital currency. The central entity computer causes removal of the physical currency from circulation in a fiat currency system.

A method and system for providing electronic universal incentive awards processing with blockchains. Universal incentive award points are earned for academic (e.g., tutoring, homework completion, lab completion, project completion, etc.) athletic (e.g., watching sports events, participating in sports events, assisting with sports events, etc.), mentoring, volunteering, extra-curricular activities, clubs, community service and/or other selected activities. The universal incentive award points earned are stored in a blockchain. The blockchain allows the creation and use of universal electronic universal incentive award points with transparency, authentication, verification and fraud prevention. The universal incentive award points are immediately redeemable from the blockchain for goods and services. The incentive award points information can be immediately sent and received with wireless, contactless transfer of information.

Provided is a blockchain-based crowdfunding device and a crowdfunding service method using the platform, the blockchain-based crowdfunding device, comprising: a blockchain unit comprising: a membership certification part configured to treat admission and certification of the patentee and the investor as members, and function to form an electronic wallet; an electronic coin issuance part configured to issue an electronic coin which can be traded in an electronic money exchange bureau and can be used in a scope of all the business carried out in the patent value coin platform; and a patent value coin issuance part configured to issue a value coin that is intended for securing a right and value owned by the patentee and investor and can be used for the right and value only when crowdfunding is performed in the crowdfunding device; and a funding service unit comprising: a patent art provision part configured to quantify value of a patent art, thereby calculating an amount of money corresponding to the quantifying value; a funding channel management part configured to connect the investor and the patentee with each other, cause them to hold mutual information in common, and provide a code corresponding to the patent art; and a service promotion management part configured to provide the patentee and the investor of a funding channel with various service promotions.

The present disclosure generally relates to the field of digital currency, more particularly, cryptocurrency and secure payment systems using Public-key cryptography. The new cryptocurrency system utilizes digitally locked coins that can be owned and exchanged anonymously without the need for any owner account. Coin owners exchange coins by sending the digital keys of the coins, and recipients use the received digital keys to change the digital locks of the received coins. The digitally locked coins are tracked in a public book that is maintained centrally or distributively by one or more bookkeepers. The new cryptocurrency system is efficient and provides fast, anonymous, and secure transactions.

A road usage charge system uses a proprietary blockchain to conduct transactions for road usage fees. While driving, a mobile device or equivalent tracks the vehicle location, speed, time of day, day of week, and any other parameter that may be used to modify a base road use fee are tracked and applied to conditional modifiers of the smart contract to create a new transaction block. As a result, the tedious reconciliation process normally associated with vehicular payments can be avoided.

The present invention relates to a system and a method of securing cryptocurrency by a precious object, wherein the value of cryptocurrency is backed by the precious object. The system of present invention comprises a cryptocurrency issuer institution which owns the precious object, wherein the precious object is divided into a plurality of 3D fragments, each of which represented by one cryptocurrency coin, created by the cryptocurrency issuer institution. The main purpose of present invention is to allow any person including normal people with small savings, to invest in the precious object through the cryptocurrency. The system and method of the present invention address many substantial advantages over traditional way of investment.

A cryptocurrency mining method and a cryptocurrency mining controller device are provided. The method includes: obtaining electricity price information and cryptocurrency price information; determining operation control parameters of the cryptocurrency mining system according to the electricity price information and the cryptocurrency price information; and controlling an operation of a target group of cryptocurrency miners according to the operation control parameters. The operation includes switching between operation states, and the operation states includes at least a running state and an off state.

A method for acceptance of blockchain payment at a traditional point of sale device direct to a merchant includes: receiving an authorization request for a fiat payment transaction including a transaction account number, transaction amount, and merchant identifier; identifying blockchain payment acceptance for a transaction account associated with the transaction account number; transmitting an address request to an exchange server including the merchant identifier; receiving a destination address associated with the merchant identifier for a blockchain network from the exchange server; transmitting a new blockchain transaction to a blockchain node in the blockchain network including the destination address and a cryptocurrency amount based on the transaction amount; and transmitting an authorization response for the fiat payment transaction to a payment network for routing to a point of sale device, the authorization response including an indication that clearance and settlement of the fiat payment transaction is not required.
