# Compatibility

## The Pantos ecosystem

The Pantos ecosystem is composed of:

* [Pantos Protocol](https://github.com/pantos-io/docs/blob/main/general/XXXX/README.md)

  The protocol defines the collection of functions exposed in order to get the expected functionality. The signature of this functions can be found [here](https://github.com/pantos-io/docs/blob/main/general/XXXXX/README.md).
* [Ethereum Contracts](https://github.com/pantos-io/ethereum-contracts)

  A collection of contracts that implement the Pantos protocol.
* [Service Node](https://github.com/pantos-io/servicenode)

  A baseline implementation of a node interacting with the Pantos protocol and the multiple supported blockchains. A service node MUST be able to interact with the latest Pantos Protocol deployed.
* [Validator Node](https://github.com/pantos-io/validatornode)

  A node responsible for validating cross-chain transfers on behalf of the users.

## About the versioning of the Pantos Protocol

The Pantos Protocol is versioned using [semantic versioning](https://semver.org) following the `major.minor.patch` naming convention (e.g. `0.1.0`). However, due to the nature of the protocol version increments reflecting new patches are not expected to happen as a patch in the signature of an existing function would define new functionality.

## Compatibility matrices

The following matrices summarize the compatibility between the versions of the Pantos protocol and the components of the Pantos ecosystem.

| ------------------ | -------------------- |
|                    | 0.1.0                |
| 2.0.0              | :heavy\_check\_mark: |
| 2.1.0              | :heavy\_check\_mark: |

| Service Node | Pantos Protocol      |
| ------------ | -------------------- |
|              | 0.1.0                |
| 1.8.1        | :heavy\_check\_mark: |

| Validator Node | Pantos Protocol      |
| -------------- | -------------------- |
|                | 0.1.0                |
