A 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.

Methods and devices for propagating blocks in a blockchain network. At a first mining node, while hashing a first block header of a first candidate block, the first mining node sends, to other mining nodes, a first message specifying transactions and their order in a first ordered set of transactions contained in the first candidate block. To prevent the other nodes from relying on the first mining node having validated the transactions in the candidate block, the first mining node seeds the first ordered set with one or more invalid transactions to create a poisoned ordered set, and provides an encrypted list identifying the invalid transactions. Once a proof-of-work is found for the candidate block, the first mining node provides a decryption key to decrypt the encrypted list and identify the invalid transactions. It may further provide replacement transactions for the invalid transactions.

A permissioned blockchain, using off-chain storage, provides advantages over blockchains that rely on consensus and/or store information within the blockchain. Advantages include enhanced viability, compactness, and the ability to register material with distribution limitations (e.g., military classified). Examples create an immutable public record of data signatures that confirm when data is intact, without distributing the data itself, so that widespread availability of the blockchain (beyond those privileged to see the data) advantageously increases the size of the community that is able to detect spoofing or forgery attempts. A permissioning entity limits submissions to manage blockchain growth, foreclosing problematic material that may risk long-term viability. Examples render blockchain operations resistant to advanced persistent threats (APTs), leverage digital signatures as additional trust elements for high-risk data, link records to track pedigree and enable identification of superseded (obsolete) data, and leverage out-of-band date proof to enable independent verification of integrity and no-later-than data-of-existence.

A method performed in a layered network. The layered network comprises a core layer comprising one or more core nodes, one or more intermediate layers each comprising one or more intermediate layer nodes, and one or more outer layers each comprising one or more outer layer nodes. Each core node is a node of a blockchain network. At least some intermediate layer nodes are database nodes. At least some outer layer nodes are client nodes. Each database node stores at least part of a distributed database. The method comprises, at a database node: receiving one or more update requests from one or more client nodes requesting to update a database entry; and for each update request, applying the update locally and/or forwarding to another database node. At least one transaction including an indication of the one or more update requests is also recorded on a blockchain of the blockchain network.

This application provides a validation method for a blockchain network, applied to a validation system for a blockchain network. The system validates a transaction through token staking. The system includes a plurality of decentralized application nodes and a distributed validator technology DVT network. A sum of tokens for staking held by the plurality of decentralized application nodes meets a staking requirement. The method includes: The plurality of decentralized application nodes aggregate, by using a key aggregation algorithm, public keys held by the plurality of decentralized application nodes, to generate a public address of the blockchain network, and separately transfer the tokens to the public address. The plurality of decentralized application nodes transfer the tokens at the public address to a staking account, generate a plurality of staking private keys, and allocate the plurality of staking private keys to the DVT network. A plurality of DVT nodes sign a transaction by using the staking private keys respectively held by the plurality of DVT nodes, to obtain an aggregated signature, and then provide the aggregated signature for a consensus node, to participate in validation of the transaction. In this way, a scope of trusted staking is expanded, and use scenarios are prevented from being limited by staking conditions.

0000 A device and method provide a visible or audible indication of whether an integrated circuit (IC) is authentic using cryptographic hashes stored on a blockchain. The IC includes a cryptographic mining circuit that creates blocks for storage in the blockchain. Each such block includes the value of a cryptographic hash function applied to a serial number unique to the IC and the hash value most recently stored in the blockchain. The necessary data are communicated between the IC and a blockchain server by an intermediary electronic authentication device, which also receives data from the server that indicate whether the second hash value equals an expected hash value computed by (or provided to) the server. The electronic authentication device accordingly provides a suitable visible or audible message to a user.
