| Issuer | None |
| Publishing Entity Overview | Publishing Program’s Organization・Shared management by recorder of Unspecified Holding・Transfer management ledger |
| Issue method | In order to maintain ledger data for distributed Held value and Transfer value, cryptocurrency is issued as compensation/indemnification for the recorder conducting cryptography calculation and value recording |
| Issuable quantity | 20,999,999.9769BTC |
| Recording Transfer value and information using electronic information processing system method | Public Blockchain |
| Confidentiality of Held・Transfer records | Hash function （SHA-256、RIPEMD-160）, Recording of Encryption process application data of Elliptic Curve Public Key Encryption |
| Ensuring Credibility Mechanism of Transfer Value records | Proof of work Consensus Algorithm, (a formula to eliminate fraud transactions within distributed ledger in which all recording members must give consent) is one of the methods of distributed ledger transaction being approved by all recording members when achieving a certain calculated amount has been confirmed by recorders as well as by administrators. |
| Transfer value confirmation mechanism | Ledger format. Recorders will decode encrypted data required for Transfer value confirmation. The authenticity of users and transfer content will be confirmed and will be settled as recordings in Transfer value record Ledger. |
| Transfer Value Network Reliability Explanation | Open network vulnerability , depending on encryption chain of ledgers (blockchain), or depending on recorder majority voting, adopting an authentication mechanism for confirmation. Depending on the number of the participation recorders into the network, eliminating the functions of data tampering, and ensuring reliability. |
| Recorder Credibility Explanation | Due to the agreement of several recorders fraud can be prevented, with a sufficient number of recorders, not have to rely on recorders individually, record maintenance mechanism is the foundation of its reliability. |
