# From UTXOs to Ownership: How BSV Records Property

#### Satoshis as Property

When a **transaction** is added to the BSV ledger, it serves as a **timestamped record of ownership change**.

* **Satoshis are not “sent” or “received”** like in a bank account.
* Instead, satoshis are tied to **UTXOs (Unspent Transaction Outputs)**, which act as **property tags**.
* Ownership changes are recorded in transactions, similar to how the ownership of **gold** is transferred without moving the physical gold.

👉 **Important note:** Although satoshis behave like property, **BSV is not digital gold** — it is a **scalable electronic cash system**.

***

#### Tracing Ownership

Because the **BSV ledger is public**, the history of all **2.1 quadrillion satoshis** can be traced back to their **issuance in 2009**.

* Each satoshi’s history is linked by a **chain of digital signatures** across UTXOs and transactions.
* Bitcoin does **not use accounts**. Instead:
  * **Identity is pseudonymously tied** to each UTXO.
  * **Macro-level activity is visible** across the network.
  * **Individual privacy is preserved** at the micro-level.

👉 This system also creates **flexibility**: transactions don’t need to be submitted by “account holders.” Anyone can submit a valid transaction, as long as it provides the correct **digital signature**.

***

#### Identity and Communication

Even though Bitcoin is pseudonymous, **identity remains a fundamental part of communication**.

* **UTXOs are traceable**, and identity can be **attributed when necessary** (e.g., for legal or compliance requirements).
* Digital systems in general rely on two core principles:
  1. **Shared secret or signal** → ensures parties know they are communicating with the correct counterpart.
  2. **Identity attribution** → links a document or message to its rightful owner.

The two most common cryptographic tools that make this possible are:

* **Diffie-Hellman key exchange** (secure communication channel).
* **Digital signatures** (ownership and authenticity verification).

***

✅ **Summary:** In BSV, **satoshis function as property** tagged by UTXOs. The public ledger makes ownership histories transparent, while pseudonymity protects individual privacy. Identity and security are preserved through **key exchanges** and **digital signatures**, forming the basis of Bitcoin’s trust model.
