# Flare Systems Protocol

Secure Flare Network oracle data.

Human URL: <https://stakecore.org/#/flare/fsp>

## Basic information

Flare Systems Protocol is a protocol consisting of three parts — FTSO (Flare
Time Series Oracle), Fast Updates, and FDC (Flare Data Connector). Rewards are
distributed based on the delegated provider's performance in each 3.5-day
epoch. The site shows statistics for the last 25 reward epochs. Note that a
reward epoch on Flare Network lasts 3.5 days.

## Delegating

Delegation on FSP is a vote, not a transfer. Wrapped FLR stays in the holder's
own wallet, there is no lockup, and StakeCore never takes custody. Delegation
is signed in the holder's wallet on the page itself — see the
[agent guide](/AGENTS.md) for why this step cannot be automated on a holder's
behalf.

## Live statistics

The page carries the provider's current delegation total, delegator count,
reward rate, and per-epoch performance across the last 25 epochs, alongside the
protocol's specification table and the contract addresses behind it. Those
figures refresh continuously and are read from the public API:

```bash
curl -s https://backend.stakecore.org/api/fsp/info/flare
```

A single delegator's position:

```bash
curl -s https://backend.stakecore.org/api/fsp/delegator-info/flare/{delegator}
```

Every figure is verifiable on the
[Flare Systems Explorer](https://flare-systems-explorer.flare.network) and the
[Flare block explorer](https://flare-explorer.flare.network).
