Answer

The patent US11488176B2 obtained by Salesforce involves distributed ledger technology, blockchain platform, smart contracts, cloud computing environment and other technical fields.

Blockchain technology solves the problems of centralized risk, inefficiency, data security, etc. in traditional financial systems through its decentralized, transparent and tamper-proof characteristics.

A smart contract is a piece of code stored on a blockchain that can automatically execute pre-set agreement terms. Smart contracts can improve transaction efficiency, reduce transaction costs, and ensure transaction security.

A forked blockchain refers to a branch that starts from a certain block on the basis of the original blockchain to form two or more independent blockchains. A forked blockchain can extend the functionality of a blockchain, such as supporting different consensus mechanisms or application scenarios.

A sidechain is an independent blockchain connected to the main chain that can interact with the main chain for assets or data. A sidechain can extend the functionality of the main chain, such as increasing transaction speed or protecting user privacy.

The consensus mechanism is a mechanism for all nodes in the blockchain network to reach an agreement, which ensures the security and consistency of blockchain data. Common consensus mechanisms include proof of work (PoW) and proof of stake (PoS).

E-commerce platforms can write product information into the blockchain to generate a unique digital identity. Consumers can query the product information on the blockchain by scanning the QR code on the product or other means to verify the authenticity of the product.

Merkle tree is a binary tree structure that can store the hash values ​​of a large number of data blocks in the leaf nodes of the tree, and recursively calculate the hash values ​​of the upper nodes to finally obtain a root hash value. Merkle tree can efficiently verify the integrity of blockchain data and facilitate data indexing and retrieval.

Private blockchains are only accessible to internal personnel, public blockchains allow anyone to join, and permissioned blockchains control the permissions of participants.

Smart operations can be declared by defining a new custom function, which specifies the basic function to be called, the additional required fields to be captured, and the function name. Smart contracts can be associated with custom functions to perform verification and add transactions to the blockchain.

Key Glossary

Blockchain: A decentralized distributed ledger technology that forms an unalterable data chain by packaging data into blocks and connecting data blocks using cryptographic technology.

Smart Contract: A piece of code stored on the blockchain that can automatically execute pre-set agreement terms.

Distributed Ledger Technology (DLT): A data storage and management method in which data is distributed and stored on multiple nodes, each node has a complete copy of the database, and the nodes use a consensus mechanism to ensure data consistency.

Fork: A blockchain branches from a certain block to form two or more independent blockchains.

Sidechain: An independent blockchain connected to the main chain that can interact with the main chain for assets or data.

Consensus Mechanism: A mechanism for all nodes in the blockchain network to reach consensus, which ensures the security and consistency of blockchain data.

Proof of Work (PoW): A consensus mechanism that requires nodes to perform a lot of computing work to obtain accounting rights.

Proof of Stake (PoS): A consensus mechanism that allocates accounting rights based on the amount of equity held by nodes.

Digital Twin: A digital representation of a physical entity or process that can simulate the behavior of a physical entity or process and provide real-time data and analysis.

Merkle Tree: A binary tree structure used to efficiently verify the integrity of blockchain data and facilitate data indexing and retrieval.

Private Blockchain: A blockchain that is only accessible to internal personnel, usually used for data management within an enterprise.

Public Blockchain: A blockchain that allows anyone to join, such as Bitcoin and Ethereum.

Permissioned Blockchain: A blockchain that controls the permissions of participants, usually used in alliance chains or industry chains.

Cloud Computing: A computing model based on the Internet, where users can obtain computing resources on demand through the network.
