Abstract: A cryptocurrency system with a communication channel, a wallet, where the wallet has a paycode and associated private key and the paycode is associated to enhanced identity. The wallet can send a zero knowledge proof on the communication channel to prove ownership of the private key and thus proof of the enhanced identity information. The wallet may include a blockchain address and associated private key. The wallet may send a zero knowledge proof on the communication channel to prove ownership of the blockchain address and thus provide proof of funds. The cryptocurrency system may include a communication channel, a wallet with a private key, where the wallet can send a zero knowledge proof on the communication channel to prove control of the private key.

Abstract: A cryptocurrency wallet included preloaded data that consists of a copy of the addresses involved in blocks from a blockchain. The wallet updates the account balance to the most recent block by examining the preloaded copy of addresses involved in blocks, and then retrieving the addresses involved in blocks absent in the preloaded data. The preloaded data in the wallet may be compressed, and the compression may utilize Golomb-Rice encoding sets for compression. Additionally, the preloaded data may be stored in binary format.

Abstract: A cryptographically secured voting process that includes applying a blinding process on a voting serial number during registration to hide the vote serial number from a registration authority so there is no way for the registration authority to associate the voting serial number with an identity credential of a voter. The voting process may include applying to a ballot an encrypted voting ticket identifier where the ballot has vote selections, y, and the encrypted voting ticket identifier is s?(x), where, x is a voting ticket id, and function s?( ) is private signer function of an election authority. The voting ticket identifier may be randomly generated. The voting process furthermore including: applying to the ballot an error check hash of the vote selections and the encrypted voting ticket identifier where the error check hash=h(y+s?(x)), where y+s?(x) is a concatenation of y and s?(x).

Abstract: A crypto expansion card including a computer interface, a secure computing enclave having a secure microcontroller unit running smart contracts. The computer interface can couple the computer expansion card to a computing device. The secure computing enclave may be coupled to the computer interface. The secure computing enclave includes a secured micro controller unit configured to run smart contacts by: receiving a cryptographic request via the computer interface, verifying the cryptographic request is properly signed and processing the verified cryptographic request. The processing of the verified cryptographic request includes using a private cryptographic security key. The processing of the verified cryptographic request on the secure micro controller unit may include using the private cryptographic security key to generate a cryptographic signature that may be part of a multi signature address.

Abstract: The crypto hardware wallet system with a secure crypto processing environment and a secure transaction authorization device. Where the secure crypto processing environment is on a single die IC with encrypted memory that holds an encrypted entry that has sensitive data. An encryptor/decryptor is coupled to the encrypted memory and decrypts the encrypted entry using an internal security mechanism. A micro controller unit coupled to the encryptor/decryptor requests and receives the sensitive data. The micro controller unit receives a request and uses the sensitive data to fulfill the request. The internal security mechanism may include an internal cryptographic key derived from a micro radiation source. The secure transaction authorization device may include a secure computing environment and a user experience device coupled to the secured computing environment via a switch. Where the secure computing environment controls whether the user experience device is communicating to the secured processing environment.

Abstract: A hybrid crypto process includes calling an on-chain smart contract function. The smart contract function receives a ghost blockchain address. Then the hybrid crypto function can call an oracle function with arguments that include the ghost blockchain address. The oracle function is associated to a program payment code and the oracle function can determine from the ghost blockchain address a payment code. If the request is to receive crypto assets, then the payment code is a sender payment code. The request may include a crypto asset amount and the oracle function may associate the crypto asset amount with the sender payment code. If the request is to send crypto assets, then the payment code is a destination payment code, and the oracle function returns a destination blockchain address. The ghost blockchain address may be generated according to BIP 33, BIP 47 or OBPPV5.
