Efficient peer-to-peer distributed ledger entity transfer method and system

Glossary

Term DefinitionsBlockchainA peer-to-peer electronic ledger implemented as a decentralized, distributed computer-based system consisting of blocks, which in turn consist of transactions. Transaction (Tx)A data structure that encodes the transfer of control of digital assets between participants in a blockchain system and contains at least one input and one output. ScriptA small program embedded in the inputs and outputs of a transaction that specifies how and by whom the output of a transaction can be accessed. Unspent Transaction Output (UTXO)A transaction output that has not been used as an input for any other transaction. Smart ContractA computer program designed to automatically execute the terms of a machine-readable contract or agreement. Tokens (or colored coins)A digital asset used to represent and transfer real-world entities over a blockchain. MetadataData embedded in a script associated with a blockchain transaction (Tx) that provides additional information about the transaction. P2SH (Pay to Script Hash)A type of Bitcoin transaction in which payments are not sent to a Bitcoin address but to a hash representing a redemption script. Distributed Hash Table (DHT)A distributed database used to store key-value pairs where any participating node can retrieve the value associated with a given key. Invitation TransactionA transaction posted and recorded on a P2P DL that indicates a user's desire to exchange specific entities and conditions. Exchange TransactionA transaction executed after matching two users' invitations, representing the actual exchange of entities. Escrow Service ProviderAn entity that acts as a neutral third party to a transaction, holding a user's offer (e.g., bitcoins or tokens) until the transaction is completed.

Short Answer Question

What are the two main advantages of blockchain technology?

Permanent, tamper-proof record of events.

Distributed processing.

How do smart contracts differ from traditional contracts?

Smart contracts are machine-executable programs that contain rules that can process inputs to produce results, and actions can then be performed based on those results, while traditional contracts are written in natural language.

What does tokenization mean in the context of blockchain technology?

Tokenization refers to the use of tokens to represent and transfer real-world assets or digital assets. Tokens act as identifiers that allow real-world items to be referenced from the blockchain.

What is the purpose of the "scripts" associated with blockchain transactions (Tx) described in this invention?

Scripts specify how and by whom the outputs of a transaction can be accessed. They are small programs embedded into the inputs and outputs of a transaction.

What is a P2SH transaction and how does it relate to the present invention?

A P2SH transaction is a type of Bitcoin transaction where payments are not sent to a Bitcoin address but to a hash representing a redeem script. The present invention uses P2SH transactions to embed metadata into blockchain transactions.

Explain how metadata is used in the present invention without changing the underlying blockchain protocol.

Metadata is placed in the redeem script in a location normally occupied by a public key. Since the blockchain protocol does not interpret data in this location, metadata can be transferred without changing the protocol.

Describe the role of an escrow service provider in the present invention.

An escrow service provider holds a user's offer (Bitcoins or tokens) until the transaction is completed. This guarantees that the user making the offer has sufficient funds to complete the exchange.

What is the purpose of an "invite" in the context of the present invention?

An invitation is an offer posted and recorded by a user on a P2P DL to exchange specific entities and conditions. It acts as an advertisement or order for a transaction.

Provide three example conditions that can be included in an "invite" related to an exchange.

Deadline: specifies the date and/or time by which the order must be completed.

Location: specifies the geographic area in which the transaction must take place.

Exchange rate: specifies the exchange rate between two entities accepted by both parties to the transaction.

How does the transaction process differ when "goods/services" are involved in the transaction instead of tokens?

When goods/services are involved, the transaction includes a description of the goods or services being exchanged rather than a token represented by a contract or title deed. The description may not uniquely identify the item, and the final transaction may not be recorded on the P2P DL because it is not used to transfer any value between the parties.
