# BBP Hex Algorithm

Picoin currently uses the BBP hexadecimal algorithm.

The Bailey–Borwein–Plouffe (BBP) formula allows direct computation of distant hexadecimal digits of π without calculating all previous digits.

This property makes BBP particularly suitable for distributed verification.

The BBP formula is defined as:

```
π = Σ (1 / 16^k) × (
    4 / (8k + 1)
  - 2 / (8k + 4)
  - 1 / (8k + 5)
  - 1 / (8k + 6)
)
```

Advantages:

* random access computation;
* efficient verification;
* deterministic outputs;
* scalable distributed tasks.

Picoin currently uses:

bbp\_hex\_v1

```
BBP hexadecimal implementation version 1
```

as the primary mining algorithm.

Future versions may support additional algorithms.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://solvency.gitbook.io/picoin/mining/bbp-hex-algorithm.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
