"abstract": "\nA blockchain system has an identity-based blockchain account including a primary chain, a secondary chain, and at least one key book applying to the account, the at least one key book having a key page. The system includes: a hardware processor; and a memory device storing instructions. When the instructions are executed by the processor, they cause the processor to: record a multi-signature transaction originating from the account in the secondary chain; associate the transaction with the key page of the at least one key book, the key page including (i) a signature-authorization rule, and (ii) a plurality of keys corresponding to a plurality of transaction authorizers; record, in the secondary chain, an authorization of the transaction from a transaction authorizer of the plurality of transaction authorizers; and once a number of authorizations recorded on the secondary chain satisfies the signature-authorization rule, record the transaction on the primary chain for execution.\n"

"title": "Transactional sharding of blockchain transactions",
"abstract": "\nA complex cryptographic coinage transaction is transactionally sharded into multiple simple cryptographic coinage transactions. The complex cryptographic coinage transaction specifies cryptographic debits and/or deposits to/from multiple input accounts and/or multiple output accounts. The simple cryptographic coinage transactions, however, only specify a single one of the input accounts and/or a single one of the output accounts. A single server within a blockchain environment may thus process one of the simple cryptographic coinage transactions without requiring calls for data from other servers responsible for other accounts.\n"

"title": "Import and export in blockchain environments",
"abstract": "\nImportation and exportation allows software services in blockchain environments. Blockchains may import data and export data, thus allowing blockchains to offer software services to clients (such as other blockchains). Individual users, businesses, and governments may create their own blockchains and subcontract or outsource operations to other blockchains. Moreover, the software services provided by blockchains may be publically ledgered by still other blockchains, thus providing two-way blockchain interactions and two-way ledgering for improved record keeping.\n"

"title": "Load balancing in blockchain environments",
"abstract": "\nHardware and software resources are load balanced when processing multiple blockchains. As more and more entities (whether public or private) are expected to generate their own blockchains for verification, a server or other resource in a blockchain environment may be over utilized. For example, as banks, websites, and retailers issue their own private cryptocoinage, the number of financial transactions may clog or hog networking and/or hardware resources. A blockchain load balancing mechanism thus allocates resources among the multiple blockchains.\n"

"title": "Computer system and method for programmatic collateralization services",
"abstract": "\nA computer system processes a digital representation of an illiquid asset, to confirm accuracy of the digital representation and value of the asset, and generates an asset-information table indicating where the various sections of the digital representation are stored. The system also generates an asset-value token, financial-return tokens, and a data structure that includes a self-executing program. The program associates the asset-value token with the financial-return tokens, so that the illiquid asset becomes a collateral for a decentralized loan transaction implemented using blockchain technology. The use of blockchain technology for decentralized loan transactions enables immutable data traceability.\n"

"title": "Validating authenticity of electronic documents shared via computer networks",
"abstract": "\nAuthentication of electronic document is based on multiple digital signatures incorporated into a blockchain. Structured data, metadata, and instructions may be hashed to generate the multiple digital signatures for distribution via the blockchain. Any peer receiving the blockchain may then verify an authenticity of an electronic document based on any one or more of the multiple digital signatures incorporated into the blockchain.\n"

"title": "Smart contracts in blockchain environments",
"abstract": "\nDigital or “smart” contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular decision table and/or the digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the decision table and/or the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements.\n"

"title": "Auditing of electronic documents",
"abstract": "\nAuditing of mortgage documents is faster and simpler. An electronic mortgage application often contains or references a collection of many separate electronic mortgage documents. Electronic data representing an original version of an electronic mortgage document and its current version may be hashed to generate digital signatures. Any auditor may then quickly compare the digital signatures. If the digital signatures match, then the audit reveals that the electronic mortgage document has not changed since its creation. However, if the digital signatures do not match, then the electronic mortgage document has changed since its creation. The auditor may thus flag the electronic mortgage document for additional auditing processes.\n"
