Gno is an interpreted and fully-deterministic implementation of the Go
programming language, designed to build succinct and composable smart contracts.
The first blockchain to use it is gno.land, a
[Proof of Contribution](./docs/concepts/proof-of-contribution.md)-based chain, backed by
a variation of the [Tendermint](https://docs.tendermint.com/v0.34/introduction/what-is-tendermint.html)
consensus engine.

The Cosmos SDK is a framework for building blockchain applications. [CometBFT (BFT Consensus)](https://github.com/cometbft/cometbft) and the Cosmos SDK are written in the Go programming language. Cosmos SDK is used to build [Gaia](https://github.com/cosmos/gaia), the implementation of the Cosmos Hub.

**WARNING**: The Cosmos SDK has mostly stabilized, but we are still making some breaking changes.

**Note**: Always use the latest maintained [Go](https://go.dev/dl) version for building Cosmos SDK applications.

## Quick Start

To learn how the Cosmos SDK works from a high-level perspective, see the Cosmos SDK [High-Level Intro](https://docs.cosmos.network/v0.50/learn/intro/overview).

If you want to get started quickly and learn how to build on top of Cosmos SDK, visit [Cosmos SDK Tutorials](https://tutorials.cosmos.network). You can also fork the tutorial's repository to get started building your own Cosmos SDK application.

For more information, see the [Cosmos SDK Documentation](https://docs.cosmos.network).

## Contributing

See [CONTRIBUTING.md](./CONTRIBUTING.md) for details on how to contribute and participate in our [dev calls](./CONTRIBUTING.md#teams-dev-calls).
If you want to follow the updates or learn more about the latest design then join our [Discord](https://discord.gg/interchain).

## Tools and Frameworks

The Cosmos ecosystem is vast.
[Awesome Cosmos](https://github.com/cosmos/awesome-cosmos) is a community-curated list of notable frameworks, modules and tools.

### Inter-Blockchain Communication (IBC)

The IBC module for the Cosmos SDK has its own [cosmos/ibc-go repository](https://github.com/cosmos/ibc-go). Go there to build and integrate with the IBC module.

### Version Matrix

The version matrix below shows which versions of the Cosmos SDK, modules and libraries are compatible with each other.

#### Core Dependencies

Core dependencies are the core libraries that an application may depend on.
Core dependencies not mentioned here as compatible across all maintained SDK versions.

| Cosmos SDK | cosmossdk.io/core | cosmossdk.io/api | cosmossdk.io/x/tx |
| ---------- | ----------------- | ---------------- | ----------------- |
| 0.52.z     | 1.y.z             | 0.8.z            | 0.14.z            |
| 0.50.z     | 0.11.z            | 0.7.z            | 0.13.z            |
| 0.47.z     | 0.5.z             | 0.3.z            | N/A               |

#### Module Dependencies

Module Dependencies are the modules that an application may depend on and which version of the Cosmos SDK they are compatible with.

> Note: The version table only goes back to 0.50.x, as modules started to become modular with 0.50.z.
> X signals that the module was not spun out into its own go.mod file.
> N/A signals that the module was not available in the Cosmos SDK at that time.

CometBFT is a Byzantine Fault Tolerant (BFT) middleware that takes a
state transition machine - written in any programming language - and securely
replicates it on many machines.

CometBFT is the canonical implementation of the Tendermint consensus algorithm and is a
primary building block for the [Interchain Stack](https://interchain.io/). Historically,
CometBFT originated as a fork of [Tendermint Core][tm-core] in early 2023
(announcement [here][comet-announcement]) and since then it diverged significantly by adopting modern features such as [PBTS][pbts] or [ABCI v2][abci-v2].

For protocol details, refer to the [CometBFT Specification](./spec/README.md).

For detailed analysis of the Tendermint consensus protocol, including safety and liveness
proofs, read our paper, "[The latest gossip on BFT
consensus](https://arxiv.org/abs/1807.04938)".

## Contributing

Please abide by the [Code of Conduct](CODE_OF_CONDUCT.md) in all interactions.

Before contributing to the project, please take a look at the [contributing
guidelines](CONTRIBUTING.md) and the [style guide](STYLE_GUIDE.md). You may also
find it helpful to read the [specifications](./spec/README.md), and familiarize
yourself with our [Architectural Decision Records
(ADRs)](docs/references/architecture/README.md) and [Request For Comments
(RFCs)](docs/references/rfc/README.md).

## Versioning

As of v1, CometBFT uses the following approach to versioning:

- **Major version** bumps, such as v1.0.0 to v2.0.0, would generally involve
  changes that _force_ users to perform a coordinated upgrade in order to use
  the new version, such as protocol-breaking changes (e.g. changes to how block
  hashes are computed and thus what the network considers to be "valid blocks",
  or how the consensus protocol works, or changes that affect network-level
  compatibility between nodes, etc.).
- **Minor version** bumps, such as v1.1.0 to v1.2.0, are reserved for rolling
  out new features or substantial changes that do not force a coordinated
  upgrade (i.e. not protocol-breaking), but could potentially break Go APIs.
- **Patch version** bumps, such as v1.0.0 to v1.0.1, are reserved for
  bug/security fixes that are not protocol- or Go API-breaking.

### Upgrades

We do not guarantee compatibility between major releases of CometBFT. Minor
releases of the same major release series (v1.1, v1.2, etc.) should, unless
otherwise specified, be compatible with each other. Patch releases of the same
minor release series (v1.0.1, v1.0.2, etc.) are guaranteed to be compatible with
each other.

For more detailed information on upgrading from one version to another, see
[UPGRADING.md](./UPGRADING.md).

### Supported Versions

Because we are a small core team, we have limited capacity to ship patch
updates, including security updates. Consequently, we strongly recommend keeping
CometBFT up-to-date. Upgrading instructions can be found in
[UPGRADING.md](./UPGRADING.md).

Currently supported versions include:

- v1.x: Currently in pre-release with no guarantees as to API stability until a
  release candidate is cut. See [RELEASES.md](./RELEASES.md) for details on our
  process as to API stability guarantees that can be expected of CometBFT
  pre-releases.
- v0.38.x: CometBFT v0.38 introduces ABCI 2.0, which implements the entirety of
  ABCI++
- v0.37.x: CometBFT v0.37 introduces ABCI 1.0, which is the first major step
  towards the full ABCI++ implementation in ABCI 2.0
- v0.34.x: The CometBFT v0.34 series is compatible with the Tendermint Core
  v0.34 series

> **Warning**
>
> The Gossamer Polkadot Host is pre-production software [2022-12-01]

Gossamer is a [Golang](https://go.dev/) implementation of the
[Polkadot Host](https://wiki.polkadot.network/docs/learn-polkadot-host): an
execution environment for the Polkadot runtime, which is materialized as a Web
Assembly (Wasm) blob. In addition to running an embedded Wasm executor, a
Polkadot Host must orchestrate a number of interrelated services, such as
[networking](dot/network/README.md), block production, block finalization, a
JSON-RPC server, [and more](cmd/gossamer/README.md#client-components).

## Getting Started

To get started with Gossamer, follow the steps below to build the source code
and start a development network.

### Prerequisites

[Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) is required
to acquire the Gossamer source code, and
[Make](https://tilburgsciencehub.com/building-blocks/configure-your-computer/automation-and-workflows/make/)
is used to build it. Building Gossamer requires version 1.20 or higher of
[Golang](https://go.dev/dl/).

### Installation

Clone the [Gossamer](https://github.com/ChainSafe/gossamer) repository and
checkout the `development` branch:

```sh
git clone git@github.com:ChainSafe/gossamer
cd gossamer
git checkout development
```

Build Gossamer:

```sh
make gossamer
```

Or build Gossamer _and_ move the resulting executable to `$GOPATH/bin`:

```sh
make install
```

To install Gossamer

## Use Gossamer

A comprehensive guide to
[Gossamer's end-user capabilities](cmd/gossamer/README.md) is located in the
`cmd/gossamer` directory. What follows is a guide to Gossamer's capabilities as
a Polkadot Host.

### Chain Specifications

A chain specification is a JSON document that defines the
[genesis](https://wiki.polkadot.network/docs/glossary#genesis) block of a
blockchain network, as well as network parameters and metadata (e.g. network
name, bootnodes,
[telemetry endpoints](https://wiki.polkadot.network/docs/build-node-management#monitoring-and-telemetry),
etc). It is necessary to provide Gossamer with a chain specification in order to
use it as a Polkadot Host. The Gossamer repository includes a number of chain
specifications, some of which will be used in this guide.

### Configuration Files

Gossamer exposes a number of configuration parameters, such as the location of a
chain specification file. Although it's possible to use command-line parameters,
this guide will focus on the usage of Gossamer TOML configuration files, which
define a set of configuration values in a declarative, portable, reusable
format. The chain specifications that are used in this guide are each
accompanied by one or more configuration files.

### Single-Node Development Network

The name of the Polkadot test network is "Westend", and the Gossamer repository
includes a chain specification and configuration file for a single-node, local
Westend test network.

First, initialize the directory that will be used by the Gossamer node to manage
its state:

```sh
./bin/gossamer init --force --chain westend-dev
```

Now, start Gossamer as a host for the local Westend development chain:

```sh
./bin/gossamer --chain westend-dev
```

### Multi-Node Development Network

The multi-node development network includes three participants: the Alice, Bob,
and Charlie test accounts. In three separate terminals, initialize the data
directories for the three Gossamer instances:

```sh
./bin/gossamer init --force --chain westend-local --alice
```

```sh
./bin/gossamer init --force --chain westend-local --bob
```

```sh
./bin/gossamer init --force --config westend-local --charlie
```

Then start the three hosts:

```sh
./bin/gossamer --chain westend-local --alice
```

```sh
./bin/gossamer --chain westend-local --bob
```

```sh
./bin/gossamer --chain westend-local --charlie
```

## Standalone Packages

In addition to the core functionality provided by Gossamer, we have developed some standalone packages that can be used independently. These packages are located in the `pkg` directory and serve various utility purposes. Here’s an overview of some of these packages:

### Scale

To support parity's [scale type encoding](https://docs.substrate.io/reference/scale-codec/) in golang.  
More details [here](./pkg/scale/README.md)

### Trie

The `trie` package includes multiple implementations of polkadot merkle tries. These implementations are useful for various applications requiring efficient data structures. Here are the key implementations:

#### In-Memory Trie

This implementation supports polkadot merkle tries that are stored entirely in memory. It includes features for backing up the trie using a database to ensure persistence.

#### TrieDB

An evolution of the in-memory trie, `TrieDB` introduces lazy loading capabilities from the underlying database. This approach optimizes performance and resource usage by loading data only as needed.

For more details on how to use `TrieDB`, refer to the specific [README](pkg/trie/triedb/README.md)

## Lightning Network Daemon

[![Release build](https://github.com/lightningnetwork/lnd/actions/workflows/release.yaml/badge.svg)](https://github.com/lightningnetwork/lnd/actions/workflows/release.yaml)
[![MIT licensed](https://img.shields.io/badge/license-MIT-blue.svg)](https://github.com/lightningnetwork/lnd/blob/master/LICENSE)
[![Irc](https://img.shields.io/badge/chat-on%20libera-brightgreen.svg)](https://web.libera.chat/#lnd)
[![Godoc](https://godoc.org/github.com/lightningnetwork/lnd?status.svg)](https://godoc.org/github.com/lightningnetwork/lnd)
[![Go Report Card](https://goreportcard.com/badge/github.com/lightningnetwork/lnd)](https://goreportcard.com/report/github.com/lightningnetwork/lnd)

<img src="logo.png">

The Lightning Network Daemon (`lnd`) - is a complete implementation of a
[Lightning Network](https://lightning.network) node.  `lnd` has several pluggable back-end
chain services including [`btcd`](https://github.com/btcsuite/btcd) (a
full-node), [`bitcoind`](https://github.com/bitcoin/bitcoin), and
[`neutrino`](https://github.com/lightninglabs/neutrino) (a new experimental light client). The project's codebase uses the
[btcsuite](https://github.com/btcsuite/) set of Bitcoin libraries, and also
exports a large set of isolated re-usable Lightning Network related libraries
within it.  In the current state `lnd` is capable of:
* Creating channels.
* Closing channels.
* Completely managing all channel states (including the exceptional ones!).
* Maintaining a fully authenticated+validated channel graph.
* Performing path finding within the network, passively forwarding incoming payments.
* Sending outgoing [onion-encrypted payments](https://github.com/lightningnetwork/lightning-onion)
through the network.
* Updating advertised fee schedules.
* Automatic channel management ([`autopilot`](https://github.com/lightningnetwork/lnd/tree/master/autopilot)).

## Lightning Network Specification Compliance
`lnd` _fully_ conforms to the [Lightning Network specification
(BOLTs)](https://github.com/lightningnetwork/lightning-rfc). BOLT stands for:
Basis of Lightning Technology. The specifications are currently being drafted
by several groups of implementers based around the world including the
developers of `lnd`. The set of specification documents as well as our
implementation of the specification are still a work-in-progress. With that
said, the current status of `lnd`'s BOLT compliance is:

  - [X] BOLT 1: Base Protocol
  - [X] BOLT 2: Peer Protocol for Channel Management
  - [X] BOLT 3: Bitcoin Transaction and Script Formats
  - [X] BOLT 4: Onion Routing Protocol
  - [X] BOLT 5: Recommendations for On-chain Transaction Handling
  - [X] BOLT 7: P2P Node and Channel Discovery
  - [X] BOLT 8: Encrypted and Authenticated Transport
  - [X] BOLT 9: Assigned Feature Flags
  - [X] BOLT 10: DNS Bootstrap and Assisted Node Location
  - [X] BOLT 11: Invoice Protocol for Lightning Payments

## Developer Resources

The daemon has been designed to be as developer friendly as possible in order
to facilitate application development on top of `lnd`. Two primary RPC
interfaces are exported: an HTTP REST API, and a [gRPC](https://grpc.io/)
service. The exported APIs are not yet stable, so be warned: they may change
drastically in the near future.

An automatically generated set of documentation for the RPC APIs can be found
at [api.lightning.community](https://api.lightning.community). A set of developer
resources including guides, articles, example applications and community resources can be found at:
[docs.lightning.engineering](https://docs.lightning.engineering).

Finally, we also have an active
[Slack](https://lightning.engineering/slack.html) where protocol developers, application developers, testers and users gather to
discuss various aspects of `lnd` and also Lightning in general.

## Installation
  In order to build from source, please see [the installation
  instructions](docs/INSTALL.md).

## Docker
  To run lnd from Docker, please see the main [Docker instructions](docs/DOCKER.md)

## IRC
  * irc.libera.chat
  * channel #lnd
  * [webchat](https://web.libera.chat/#lnd)

## Safety

When operating a mainnet `lnd` node, please refer to our [operational safety
guidelines](docs/safety.md). It is important to note that `lnd` is still
**beta** software and that ignoring these operational guidelines can lead to
loss of funds.

## Security

The developers of `lnd` take security _very_ seriously. The disclosure of
security vulnerabilities helps us secure the health of `lnd`, privacy of our
users, and also the health of the Lightning Network as a whole.  If you find
any issues regarding security or privacy, please disclose the information
responsibly by sending an email to security at lightning dot engineering,
preferably encrypted using our designated PGP key
(`91FE464CD75101DA6B6BAB60555C6465E5BCB3AF`) which can be found
[here](https://gist.githubusercontent.com/Roasbeef/6fb5b52886183239e4aa558f83d085d3/raw/5fa96010af201628bcfa61e9309d9b13d23d220f/security@lightning.engineering).

## Documentation

Complete documentation can be found on the
[website](https://docs.tendermint.com/).

## Releases

Please do not depend on `main` as your production branch. Use
[releases](https://github.com/tendermint/tendermint/releases) instead.

Tendermint has been in the production of private and public environments, most
notably the blockchains of the Cosmos Network. we haven't released v1.0 yet
since we are making breaking changes to the protocol and the APIs. See below for
more details about [versioning](#versioning).

In any case, if you intend to run Tendermint in production, we're happy to help.
You can contact us [over email](mailto:hello@interchain.io) or [join the
chat](https://discord.gg/cosmosnetwork).

More on how releases are conducted can be found [here](./RELEASES.md).

## Security

To report a security vulnerability, see our [bug bounty
program](https://hackerone.com/cosmos). For examples of the kinds of bugs we're
looking for, see [our security policy](SECURITY.md).

We also maintain a dedicated mailing list for security updates. We will only
ever use this mailing list to notify you of vulnerabilities and fixes in
Tendermint Core. You can subscribe [here](http://eepurl.com/gZ5hQD).

yourself with our [Architectural Decision Records
(ADRs)](./docs/architecture/README.md) and
[Request For Comments (RFCs)](./docs/rfc/README.md).

## Versioning

### Semantic Versioning

Tendermint uses [Semantic Versioning](http://semver.org/) to determine when and
how the version changes. According to SemVer, anything in the public API can
change at any time before version 1.0.0

To provide some stability to users of 0.X.X versions of Tendermint, the MINOR
version is used to signal breaking changes across Tendermint's API. This API
includes all publicly exposed types, functions, and methods in non-internal Go
packages as well as the types and methods accessible via the Tendermint RPC
interface.

Breaking changes to these public APIs will be documented in the CHANGELOG.

### Upgrades

In an effort to avoid accumulating technical debt prior to 1.0.0, we do not
guarantee that breaking changes (ie. bumps in the MINOR version) will work with
existing Tendermint blockchains. In these cases you will have to start a new
blockchain, or write something custom to get the old data into the new chain.
However, any bump in the PATCH version should be compatible with existing
blockchain histories.

For more information on upgrading, see [UPGRADING.md](./UPGRADING.md).

### Supported Versions

Because we are a small core team, we only ship patch updates, including security
updates, to the most recent minor release and the second-most recent minor
release. Consequently, we strongly recommend keeping Tendermint up-to-date.
Upgrading instructions can be found in [UPGRADING.md](./UPGRADING.md).
