Please, do not depend on it and 31 use [releases](https://github.com/tendermint/tendermint/releases) instead. 32 33 Tendermint is being used in production in both private and public environments, 34 most notably the blockchains of the [Cosmos Network](https://cosmos.network/). 35 However, we are still making breaking changes to the protocol and the APIs and have not yet released v1.0. 36 See below for more details about [versioning](#versioning). 37 38 In any case, if you intend to run Tendermint in production, 39 please [contact us](mailto:partners@tendermint.com) and [join the chat](https://riot.im/app/#/room/#tendermint:matrix.org). 40 41 ## Security 42 43 To report a security vulnerability, see our [bug bounty 44 program](https://hackerone.com/tendermint) 45 46 For examples of the kinds of bugs we're looking for, see [SECURITY.md](SECURITY.md) 47 48 ## Minimum requirements 49 50 | Requirement | Notes | 51 | ----------- | ---------------- | 52 | Go version | Go1.13 or higher | 53 54 ## Documentation 55 56 Complete documentation can be found on the [website](https://docs.tendermint.com/master/). 57 58 ### Install 59 60 See the [install instructions](/docs/introduction/install.md) 61 62 ### Quick Start 63 64 - [Single node](/docs/introduction/quick-start.md) 65 - [Local cluster using docker-compose](/docs/networks/docker-compose.md) 66 - [Remote cluster using terraform and ansible](/docs/networks/terraform-and-ansible.md) 67 - [Join the Cosmos testnet](https://cosmos.network/testnet) 68 69 ## Contributing 70 71 Please abide by the [Code of Conduct](CODE_OF_CONDUCT.md) in all interactions. 72 73 Before contributing to the project, please take a look at the [contributing guidelines](CONTRIBUTING.md) 74 and the [style guide](STYLE_GUIDE.md). 75 76 To get more active, Join the wider community at [Discord](https://discord.gg/AzefAFd) or jump onto the [Forum](https://forum.cosmos.network/). 77 78 Learn more by reading the code and the 79 [specifications](https://github.com/tendermint/spec) or watch the [Developer Sessions](/docs/DEV_SESSIONS.md) and read up on the 80 [Architectural Decision Records](https://github.com/tendermint/tendermint/tree/master/docs/architecture). 81 82 ## Versioning 83 84 ### Semantic Versioning 85 86 Tendermint uses [Semantic Versioning](http://semver.org/) to determine when and how the version changes. 87 According to SemVer, anything in the public API can change at any time before version 1.0.0 88 89 To provide some stability to Tendermint users in these 0.X.X days, the MINOR version is used 90 to signal breaking changes across a subset of the total public API. This subset includes all 91 interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not 92 include the in-process Go APIs. 93 94 That said, breaking changes in the following packages will be documented in the 95 CHANGELOG even if they don't lead to MINOR version bumps: 96 97 - crypto 98 - types 99 - rpc/client 100 - config 101 - node 102 - libs 103 - bech32 104 - common 105 - db 106 - errors 107 - log 108 109 Exported objects in these packages that are not covered by the versioning scheme 110 are explicitly marked by `// UNSTABLE` in their go doc comment and may change at any 111 time without notice. Functions, types, and values in any other package may also change at any time. 112 113 ### Upgrades 114 115 In an effort to avoid accumulating technical debt prior to 1.0.0, 116 we do not guarantee that breaking changes (ie. bumps in the MINOR version) 117 will work with existing tendermint blockchains. In these cases you will 118 have to start a new blockchain, or write something custom to get the old 119 data into the new chain. 120 121 However, any bump in the PATCH version should be compatible with existing histories 122 (if not please open an [issue](https://github.com/tendermint/tendermint/issues)). 123 124 For more information on upgrading, see [UPGRADING.md](./UPGRADING.md). 125 126 ### Supported Versions 127 128 Because we are a small core team, we only ship patch updates, including security updates, 129 to the most recent minor release and the second-most recent minor release. Consequently, 130 we strongly recommend keeping Tendermint up-to-date. Upgrading instructions can be found 131 in [UPGRADING.md](./UPGRADING.md). 132 133 ## Resources 134 135 ### Tendermint Core 136 137 For details about the blockchain data structures and the p2p protocols, see the 138 [Tendermint specification](https://docs.tendermint.com/master/spec/). 139 140 For details on using the software, see the [documentation](/docs/) which is also 141 hosted at: https://docs.tendermint.com/master/ 142 143 ### Tools 144 145 Benchmarking is provided by `tm-load-test`. 146 The code for `tm-load-test` can be found [here](https://github.com/informalsystems/tm-load-test) this binary needs to be built separately. 147 Additional documentation is found [here](/docs/tools). 148 149 ### Sub-projects 150 151 - [Amino](http://github.com/tendermint/go-amino), reflection-based proto3, with 152 interfaces 153 - [IAVL](http://github.com/tendermint/iavl), Merkleized IAVL+ Tree implementation 154 - [Tm-db](http://github.com/tendermint/tm-db), Data Base abstractions to be used in applications. 155 156 ### Applications 157 158 - [Cosmos SDK](http://github.com/cosmos/cosmos-sdk); a cryptocurrency application framework 159 - [Ethermint](http://github.com/cosmos/ethermint); Ethereum on Tendermint 160 - [Many more](https://tendermint.com/ecosystem) 161 162 ### Research 163 164 - [The latest gossip on BFT consensus](https://arxiv.org/abs/1807.04938) 165 - [Master's Thesis on Tendermint](https://atrium.lib.uoguelph.ca/xmlui/handle/10214/9769) 166 - [Original Whitepaper: "Tendermint: Consensus Without Mining"](https://tendermint.com/static/docs/tendermint.pdf) 167 - [Blog](https://blog.cosmos.network/tendermint/home)
