closes: #5770 closes: #5769 also, include node ID in the output (#5769) and modify NodeKey to use value semantics (it makes perfect sense for NodeKey to not be a pointer).

Tendermint Core is Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language -
and securely replicates it on many machines.
For protocol details, see [the specification](https://github.com/tendermint/spec).
For detailed analysis of the consensus protocol, including safety and liveness proofs,
see our recent paper, "[The latest gossip on BFT consensus](https://arxiv.org/abs/1807.04938)".
## Releases
Please do not depend on master as your production branch. Use [releases](https://github.com/tendermint/tendermint/releases) instead.
Tendermint is being used in production in both private and public environments,
most notably the blockchains of the [Cosmos Network](https://cosmos.network/).
However, we are still making breaking changes to the protocol and the APIs and have not yet released v1.0.
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.berlin) or [join the chat](https://discord.gg/AzefAFd).
## Security
To report a security vulnerability, see our [bug bounty
program](https://hackerone.com/tendermint).
For examples of the kinds of bugs we're looking for, see [our security policy](SECURITY.md).
## Minimum requirements
| Requirement | Notes |
|-------------|------------------|
| Go version | Go1.15 or higher |

## 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](https://github.com/tendermint/spec), watch the [Developer Sessions](/docs/DEV_SESSIONS.md),
and familiarize yourself with our
[Architectural Decision Records](https://github.com/tendermint/tendermint/tree/master/docs/architecture).
## 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 Tendermint users in these 0.X.X days, the MINOR version is used
to signal breaking changes across a subset of the total public API. This subset includes all
interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not
include the Go APIs.
That said, breaking changes in the following packages will be documented in the
CHANGELOG even if they don't lead to MINOR version bumps:
- crypto
- config
- libs
- bits
- bytes
- json
- log
- math
- net
- os
- protoio
- rand
- sync
- strings
- service
- node
- rpc/client
- types
### 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).
