How is blockchain product traceability traceable?

Blockchain product traceability uses distributed ledger technology and operates through the following steps: 1. Collect and encrypt product data; 2. Organize data blocks into a blockchain; 3. Decentralize storage to ensure data security; 4. Through The consensus mechanism verifies new blocks; 5. Provides transparency and allows users to audit transactions; 6. Records the product life cycle and creates trustworthy traceability records.

How blockchain product traceability works

Blockchain is a distributed ledger technology known for its security and transparency. It has been widely used for product traceability. The following is how blockchain product traceability works:

1. Data collection

First, product information (such as source, production process, transportation records) will be collected on the blockchain. This data can come from a variety of sources, such as sensors, supplier records, or consumer input.

2. Data Encryption

The data collected will be encrypted to ensure its security and privacy. Blockchain uses cryptographic algorithms to create hashes, essentially an irreversible digital fingerprint. The hash of each data block is linked to the hash of the previous block.

3. Blockchain Structure

These encrypted data blocks are organized into a sequentially linked blockchain. Each block contains a set of transactions (data entries), a timestamp, and a hash of the previous block. This creates an immutable record where any changes affect the entire chain.

4. Decentralization

The blockchain is not stored at a single entity, but is distributed across multiple computer networks. This makes it highly decentralized and not controlled by a single organization or individual.

5. Consensus Mechanism

To ensure accuracy and prevent malicious activities, blockchain uses a consensus mechanism to verify new blocks. This involves participants on the network (such as miners) reaching a consensus on which block is valid.

6. Transparency

All transactions on the blockchain are transparent and auditable. Anyone can access and verify the data via a web browser. This transparency adds credibility to the origin of the product.

In this way, blockchain can create an immutable and transparent record of a product from its development to the hands of the consumer. It documents all key stages of a product's life cycle, allowing consumers to be confident that the product they are purchasing is authentic and comes from a trustworthy source.
