Trusted Tokenized Transaction Blockchain System

Trusted Tokenized Transaction Blockchain System

Glossary

Term Definitions Blockchain consists of a chain of data blocks, each containing multiple transaction information and connected to the previous block through a hash function. Blockchain Unit A unit that can be traded in a blockchain system, such as a token. Tokenization The process of converting an asset into a blockchain unit (e.g., a blockchain token). Blockchain Deposit Receipt (BCDR) Blockchain unit that represents a tokenized asset. Smart Contract Code stored on the blockchain that automatically executes when pre-set conditions are met. Oracle Entity that provides external data to smart contracts. Exchange Server Centralized platform that provides asset trading and tokenization services. Trustee Server Trusted entity that holds assets on behalf of the beneficiary. Digital signature Encrypts data using a private key to verify data integrity and sender identity. Hash function An algorithm that converts data of arbitrary length into a fixed-length string. Public key cryptography uses a public and private key pair, where the public key can be made public and is used to encrypt data or verify signatures, and the private key must be kept secret and is used to decrypt data or generate signatures. Short Answer Questions

What is the role of a Blockchain Deposit Receipt (BCDR)?

BCDR represents a tokenized asset that can be traded on the exchange server. It acts as proof that the trustee holds the underlying asset.

How does the trustee server establish trust in the tokenization process?

The trustee server generates a digital signature by signing the hash value containing the tokenization request information with its private key. This signature proves that the trustee holds the asset and that the tokenization request information is authentic.

What role do smart contracts play in the BCDR creation process?

Smart contracts are stored on the blockchain and contain code that is executed after verifying the trustee's digital signature. The executed code generates the BCDR and records it on the blockchain.

How does the exchange server verify asset ownership?

The verification method depends on the type of asset. For securities, the exchange server can hold user shares or check with the broker. For physical assets, the server can ask for proof of ownership, such as a deed or certificate of title.

Explain what "identification information" is in the tokenization request and what it is used for.

Identification information refers to the details of the tokenization request, such as the asset identifier, quantity, user account identifier, and timestamp. It is used to generate a digital signature and verify the authenticity of the transaction.

What role does the oracle play in verifying the trustee's digital signature?

The oracle retrieves published information from a source external to the blockchain, such as the trustee's website. The smart contract compares the information provided by the oracle with the information decrypted from the digital signature to verify that the trustee actually holds the asset.

How is BCDR redeemed from the user to the underlying asset?

The user sends a redemption request to the trustee and transfers the BCDR to the trustee's blockchain address. After the trustee verifies the transfer, it returns an asset of equal value to the user and removes or marks the BCDR from the blockchain.

How does the exchange server facilitate BCDR trading between users?

The exchange server provides a platform where users can post buy and sell orders and trade BCDR for other currencies (e.g., blockchain tokens). The server matches the orders, verifies the transaction, and updates the user's account balance.

Describe the basic structure of a transaction in a blockchain.

Each transaction contains transaction data (e.g., the number of blockchain units transferred), the receiving address, the hash of the previous transaction, and the digital signature of the current owner.

How are new blocks in a blockchain generated and how are they linked together?

New blocks can be generated through mining or voting. Each new block contains the hash of the previous block, thus linking them together to form a tamper-proof chain of transaction records.
