Apparatus and methods are provided for determining AR filter coefficient and numbers of synchronization. In one novel aspect, the AR filter coefficient and times of synchronization are determined based on the temperatures of the oscillator. In one embodiment, the UE determines a temperature drift rate by collecting sets of temperatures before and after the UE in the sleep mode of the CDRX, generates one or more threshold look-up tables and performs an optimization selection based on the temperature drift rate and the one or more threshold of look-up tables, wherein the optimization selection comprising selecting an alpha coefficient and a number of subframes for synchronization. In another embodiment, the optimization selection is further determined based on a subcarrier spacing, and a channel type of being a static channel type and a fading channel type. The UE further performs an on-the-fly oscillator S-curve calibration based on the set of temperatures.

A computer-implemented method for use with a database computer system including a database data set that includes machine readable data in the form of a plurality of records, the computer-implemented method comprising: (i) defining a plurality of sets of permission rule(s); (ii) receiving a first user profile for a first user; (iii) establishing a plurality of user identities to the first user; (iv) generating a plurality of tokens; and (v) for each given user identity of the first user, adding a given token of the plurality of tokens to the first user profile and associating the given user identity and the given token.

Allocating multiple database access tokens to a single user

An example operation may include one or more of initializing a smart contract (SC) and appending it to a blockchain, registering each of a plurality of participants as a party to the SC, receiving from at least some of the participants an encrypted confidential input commitment, appending the encrypted input commitments to the blockchain, decrypting the encrypted input commitments, executing by the SC at least one business rule using the decrypted input commitments to obtain a business rule result, and identifying a prevailing participant based at least in part on the business rule result.

Ensuring information fairness and input privacy using a blockchain in a competitive scenario governed by a smart contract

An example operation may include one or more of creating, by a blockchain user of a blockchain network, a world state checkpoint transaction requesting world state validation, endorsing, by one or more endorser nodes or peers, the world state checkpoint transaction, transferring endorsements to the blockchain user, recording, by an orderer node or peer, the endorsed world state checkpoint transaction into a block, validating and committing all transactions in the block, calculating and signing a hash of a current world state, by all blockchain nodes or peers of the blockchain network, and verifying, by the blockchain user, world state integrity from the calculated and signed hashes of the current world state.

Database world state integrity validation

An example operation may include one or more processing transactions of a plurality of blocks of a blockchain of the blockchain network to determine a user of a plurality of users that is a party of the respective transaction and a mining pool of one or more mining pools that included the respective transaction in the blockchain, performing a statistical analysis of the transactions to determine if the transactions of a user of the plurality of users is distributed across the one or more mining pools in a statistically expected manner, determining that the user has a special relationship with one or more of the one or more mining pools if the transactions of the user are not distributed across the mining pools in a statistically expected manner, and for a user that is determined to have a special relationship, determining one or more of the mining pools with which the determined user has a special relationship.

Special relationships in a blockchain

An example method of operation may include one or more of identifying a number of share chains from a smart contract stored in a blockchain, identifying a contributed block received from a miner entity associated with one of the share chains, determining whether the contributed block is valid for the one share chain, and updating the one share chain based on the contributed block.

Decentralized pooled mining for enabling proof-of-work on blockchains

An example operation may include one or more of storing a first hashed timelock request in a first storage structure, where the first hashed timelock request is hashed based on a first secret, generating a second secret based on the first secret and a public key of a client, hashing the second secret to generate a hashed second secret, and transmitting a request for a second hashed timelock request to the client, where the request comprises the generated hashed second secret.

Preserving privacy of linked cross-network transactions

An example operation may include one or more of receiving one or more responses to a storage request for a blockchain from one or more endorser nodes of the blockchain, extracting transaction data of the storage request included in the one or more responses, generating a zero-knowledge proof of endorsement based on the extracted transaction data and the one or more responses, and transmitting the zero-knowledge proof to a blockchain node for inclusion within a data block among a hash-linked chain of data blocks.

Zero-knowledge proof for blockchain endorsement

Analyzing software change impact is provided. Feedback is received regarding a predicted impact of a software change to a set of components of a service. It is determined whether the predicted impact of the software change is correct based on the feedback. In response to determining that the predicted impact of the software change is correct based on the feedback, the software change is applied to the set of components of the service increasing performance of the service and a server computer hosting the service.

Analyzing software change impact based on machine learning

An example operation may include one or more of receiving, at an endorser node, a request message from a client system which comprises data to be stored on a blockchain, determining whether to endorse the data via invocation of chaincode which receives the data as input and executes the data against a current state of the blockchain, in response to a determination to endorse the data, generating a response message including a result of the execution and signing the response message based on a traceable blinded ring signature associated with the endorser node, and transmitting the generated response message that has been signed with the traceable blinded key ring to the client system.
