*In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.*

One of the most significant challenges in digital currency transactions is the **double-spending problem**. This issue arises when a user attempts to spend the same digital currency more than once. The proposed solution involves:

* **Peer-to-Peer Distributed Timestamp Server**: By utilizing a distributed timestamp server, the system can generate computational proof of the chronological order of transactions. This ensures that each transaction is recorded in a secure and verifiable manner.
* **Proof-of-work**: As transactions are created, network nodes assemble them into block templates and perform proof of work computations. This process establishes a consensus-driven agreement on the order of transactions, preventing double spending.
* **Transparent Ledger**: Transactions are recorded as plaintext on a public ledger, allowing all parties to verify the validity of transactions. This transparency enhances trust and accountability within the system.
