Abstract: There may be provided a computer-implemented method. The computer-implemented method includes: i) broadcasting, by a node in a blockchain network (such as, for example, the Bitcoin network), a transaction to transfer one or more digital assets to a public group address associated with a congress public key, the public group being associated with one or more other digital assets associated with other members of a congress; ii) generating a private key share to be used in a threshold signature scheme in which at least a threshold of private key shares must be used to generate a valid signature through combination of partial signatures on behalf of the congress, and wherein other holders of the private key shares are the other members of the congress who have joined the congress by transfer of respective digital assets to the public group address; and iii) using the private key share to cooperatively generate a valid signature for a transaction from the public group address.

Abstract: The invention relates to distributed ledger technologies such as consensus-based blockchains. Computer-implemented methods for smart contract outcome determination are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A set of conditions is determined between counterparties, with the set of conditions having a plurality of possible outcomes that includes a first possible outcome associated with a first distribution of a digital asset and a second possible outcome associated with a second distribution, different from the first distribution, of the digital asset. A counterparty transaction is created that includes, as output, the set of conditions encoded into computer-executable instructions and the digital asset. An outcome is received from a third party, with the outcome corresponding to the first possible outcome or the second possible outcome.

Abstract: A method in accordance with the invention includes: providing to a hub, from an enclave associated with a TEE at a node, an enclave public key; establishing a channel with the hub by broadcasting to a blockchain network a funding transaction which encumbers a digital asset with a first public key, a second public key and a third public key such that the encumbrance of the digital asset may be removed by: 1) both a first signature generated from a first private key corresponding to the first public key and a second signature generated from a second private key corresponding to the second public key; or 2) a third signature, valid for the third public key, the third public key associated with a group; receiving a commitment transaction encrypted with the enclave public key; detecting a failure; and issuing a failsafe activation request to the group using data from the enclave.

Abstract: There may be provided a computer-implemented method for use with a blockchain. The computer-implemented method includes: broadcasting a first deposit transaction configured to allow a first digital asset to be unlocked after a defined period of time through generation of a signature which is valid for a first public key and unlocked at any time through generation of a signature which is valid for a second public key; before expiration of the defined period of time, broadcasting a first funding transaction which encumbers a second digital asset with the first public key, the second public key and a third public key; and after expiration of the defined period of time, broadcasting a transaction unlocking the first digital asset with a signature which is valid for the first public key.

Abstract: A computer-implemented method includes: storing an encryption public key that is associated with a group of nodes, each node in the group associated with a private key share, the private key shares associated with a threshold private key reconstruction scheme for the group to allow an encryption private key associated with the encryption public key to be determined from at least a threshold of the private key shares; iteratively obtaining a plurality of indicators provided by a plurality of nodes of the group, each of the indicators representing one of an encryption private key share or a dummy signal; and identifying the encryption private key by iteratively: i) selecting a subset of the indicators; ii) calculating a possible shared secret; and iii) evaluating each possible shared secret against the encryption public key to determine whether the possible shared secret is the encryption private key. The invention is suited for implementation on a blockchain.

Abstract: A computer-implemented method is described for enabling recovery of one or more digital assets held on a blockchain by a user under a public key Pk after a corresponding private key Sk for accessing the one or more digital assets is lost. The computer implemented method comprises setting access for the one or more digital assets held on the blockchain under the public key Pk and accessible using the corresponding private key Sk of the user such that the one or more digital assets are also accessible using a private key x shared by a congress on the blockchain network, the congress comprising a group of users on the blockchain network, each member of the congress having a private key share xi, the private key share xi to be used in a threshold signature scheme in which at least a threshold of private key shares must be used to generate a valid signature through the combination of partial signatures of the congress to access the one or more digital assets on behalf of the user.

Abstract: There may be provided a computer-implemented method. It may be implemented using a blockchain such as, for example, the Bitcoin blockchain. The computer-implemented method includes: i) joining a congress by transferring, by a node operating in a proof-of-work blockchain network, one or more digital assets to a congress pool having one or more other digital assets associated with other members of a congress; ii) detecting, by the node, a special transaction of digital assets on the proof-of-work blockchain network to an address associated with the congress pool, the special transaction satisfying determined criteria; and iii) minting, by the node, one or more digital assets on a proof-of-stake blockchain network in response to detecting the special transaction.

Abstract: The present invention relates to the use of water-based control fluid in subsea systems as barrier fluid for electric motors (2) coupled to subsea pumps (1). For that purpose, a hose (HFL) (12) is arranged between an umbilical termination unit (9) and the electric motor (2) of the submersible pump (1), by means of a connection plate (MQC) (7). This installation makes more rational use of the space on the floating production unit by reducing the number of devices required for the implementation thereof, and by facilitating logistics regarding these products and devices.

Abstract: A collaboration message is received at a computer system network node of a computer network that operates in a decentralized arrangement such that network nodes comprise work process sources and destinations, and the collaboration messages convey process state updates among the collaborators. There is no central authority though which all process messages and state updates must pass and which thereby may create a system bottleneck and limit system growth. The computer system is scalable and system operation remains efficient with increasing numbers of network nodes.

Abstract: The present invention relates to methods and compositions for detecting a target nucleotide sequence in a sample. In particular, the methods and compositions of the present invention employ a reporter enzyme tethered to a solid support via a tether nucleotide sequence. A disclosed method for detecting a target nucleotide sequence comprises providing a linker nucleotide sequence comprising a probe sequence that can hybridize to the target sequence and a trigger which can hybridize to the tether nucleotide sequence when the probe sequence binds to the target. The linker nucleotide can have a stem-loop structure. When the trigger hybridizes to the tether nucleotide sequence, the tether is able to be digested by a nuclease, releasing the reporter enzyme from the solid support. The activity of the released reporter enzyme on a spatially or temporally separated substrate generates a detectable signal.
