Distributed ledger technology and asset ownership management systems

Glossary

Term DefinitionsBlockchainA distributed database that uses cryptography to ensure data security and integrity. Data is linked together in blocks to form an immutable record.Smart ContractA self-executing contract stored on a blockchain. When predefined conditions are met, the code in the contract is automatically executed.CryptocurrencyA digital or virtual currency that uses cryptography to ensure transaction security and control currency creation. It usually operates in a decentralized manner and is not controlled by a central bank.Private KeyIn cryptography, a private key is a key used to decrypt messages or sign digital signatures. The private key must be kept secret and can only be used by the owner.A public key is used in pairs with a private key to encrypt messages. Anyone can send an encrypted message using the public key, but only those with the corresponding private key can decrypt it.Cryptocurrency AddressA string of characters that represents a specific account in a cryptocurrency network. Users can receive and send cryptocurrency through the address.Distributed LedgerA database that is shared, replicated, and synchronized among multiple participants. There is no central administrator. All participants have a copy of the data.Transaction RecordAn entry on the blockchain that records the details of a cryptocurrency transaction, including the sender, recipient, amount, and timestamp. Shared ledger A ledger maintained by multiple participants, all of which can access and verify transaction records in the ledger. Rotating Credit Association (RCA) A savings and credit system in which participants contribute to a common fund on a regular basis and receive the full amount in turn. Potential Value Score (PSV) A measure of the value of adjustable load or generation resources in a power system based on a predetermined benchmark or reference value. Power Trading Block (PTB) A standardized unit for trading electricity in a power market. The size of a PTB is determined by the grid operator or independent system operator. Non-fungible token (NFT) A cryptocurrency token that represents a unique digital asset. NFTs are not interchangeable. Each token has a unique identifier and attributes.

Short Answer Question

Briefly describe how blockchain technology is used to verify transactions. Blockchain technology uses distributed networks and cryptographic algorithms to verify transactions. Each transaction is broadcast to all nodes in the network. The nodes confirm its validity by verifying the digital signature and hash value of the transaction and add the valid transaction to the block. The immutability of the blockchain ensures the reliability of transaction records.

Explain the role of smart contracts in facilitating the transfer of ownership of digital assets. Smart contracts can automatically execute predefined contract terms, including the transfer of ownership of digital assets. When the contract terms are met, smart contracts automatically execute the ownership transfer operation without the need for a third-party intermediary, thereby improving efficiency and security.

Discuss the advantages of using cryptocurrency addresses to track digital asset ownership. Each cryptocurrency address is associated with a unique private key, and only the private key owner can control and transfer the digital assets associated with the address. This mechanism ensures the clarity and security of asset ownership, and the transaction records are open, transparent, and easy to track.

Briefly describe how a rotating credit union (RCA) works. RCA members regularly contribute to a mutual fund, and one member is selected each cycle to receive the entire amount. This method can help members obtain short-term loans or savings goals, especially for groups that are difficult to reach with traditional financial services.

Explain the role of potential value scores (PSV) in power systems. PSV is used to measure the value of adjustable loads or generation resources in power systems. It can help grid operators optimize the allocation of power resources, improve the reliability and efficiency of power systems, and promote the integration of renewable energy.

Describe how power trading blocks (PTBs) facilitate transactions in power markets. PTB is a standardized unit for trading electricity in the power market. It can bring together power resources for large-scale trading, thereby improving the liquidity and efficiency of the power market.

Discuss the application of non-fungible tokens (NFTs) in the management of digital artwork ownership. NFTs can represent unique digital artworks and record their ownership information. Due to the indivisibility and uniqueness of NFTs, it can effectively solve the copyright issues of digital artworks and provide artists with new creation and sales channels.

Briefly describe how digital fingerprints can be used to verify the authenticity of physical assets. Each physical asset has unique physical characteristics, and digital fingerprints can be generated through scanning technology and stored on the blockchain. When the authenticity of the asset needs to be verified, the fingerprint scanned on site can be compared with the fingerprint stored on the blockchain.

Explain how biometric technology can be used to enhance digital identity authentication. Biometric technologies, such as fingerprints, facial recognition, and iris scanning, can be used to verify the identity of users. Compared with traditional password verification, biometric technology is more secure and reliable because it relies on the user's physiological characteristics and is difficult to forge.

Discuss the potential advantages of applying blockchain technology to intellectual property management. Blockchain can provide a secure, transparent, and traceable recording system for intellectual property. It can help streamline the IP registration, transfer and licensing process, and combat piracy and infringement.
