# Chapter 8 · The BTC Reward Pool: External Value Returned

Bedrock that grows with liquidity

### 8.1 How the Pool Forms: Buying, Injection and Fee Share

* <mark style="color:$warning;">**Continuous buying**</mark>: 60% of activation gas buys BTC (or WBTC) at market through decentralized routing, accumulating trade by trade — every millimetre of the pool's thickness comes from real activation.
* <mark style="color:$warning;">**Ecosystem injection**</mark>: BTC embodies ecosystem value directly — the protocol keeps injecting liquidity rewards as the ecosystem develops; the more it flourishes, the richer the injection, and the pool thickens in step with the tower's growth.
* <mark style="color:$warning;">**Fee share**</mark>: a settled share of subsequent ecosystem fees flows in continuously, thickening the pool over the long run.

### 8.2 Distribution and Settlement

BTC rewards and VITA rewards use <mark style="color:$warning;">**the same contribution weight S**</mark>. Once genesis stacking ends, the pool's assets vest once by weight:

* <mark style="color:$warning;">**Timing**</mark>: after genesis stacking ends the contract distributes by S from an on-chain weight snapshot — set once, verifiable throughout.
* <mark style="color:$warning;">**Withdrawal**</mark>: users may call claimBTC() at any time to withdraw vested WBTC to their own non-custodial wallet, with no manual review at any point.

### 8.3 Theoretical Scale

On current parameters, were all 2,100,000 crystals activated, the pool's theoretical cumulative scale would exceed <mark style="color:$warning;">**4,200,000 USDT in equivalent assets**</mark>。

This is a parameter-based estimate. Actual scale depends on activation gas, real activation progress, routing execution prices and the BTC market price; on-chain balances prevail. The pool address, live balance, cumulative inflow and cumulative distribution are public throughout.

# Agent Instructions
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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://vitaprotocol.gitbook.io/vita/vita-protocol/tokenomics/chapter-8-the-btc-reward-pool-external-value-returned.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
