We catch SIGINT and SIGTERM and try to clean up nicely. For other signals we |
|
|
|
use the default behaviour in Go: `Default behavior of signals in Go programs |

|
|
While actual specs vary depending on the load and validators count, minimal requirements are: |
|
|
|
|
|
|
|
- 1GB RAM |
|
|
|
- 25GB of disk space |
|
|
|
- 1.4 GHz CPU |
|
|
|
|
|
|
|
SSD disks are preffereble for applications with high transaction throughput. |
|
|
|
|
|
|
|
Recommended: |
|
|
|
|
|
|
|
- 2GB RAM |
|
|
|
- 100GB SSD |
|
|
|
- x64 2.0 GHz 2v CPU |

Operating Systems |
|
|
|
~~~~~~~~~~~~~~~~~ |
|
|
|
|
|
|
|
Tendermint can be compiled for a wide range of operating systems thanks to Go |
|
|
|
language (the list of $OS/$ARCH pairs can be found `here |
|
|
|
<https://golang.org/doc/install/source#environment>`__). |
|
|
|
|
|
|
|
While we do not favor any operation system, more secure and stable Linux server |
|
|
|
distributions (like Centos) should be preferred over desktop operation systems |
|
|
|
(like Mac OS). |

NOTE: if you are going to use Tendermint in a public domain, make sure you read |
|
|
|
`hardware recommendations (see "4. Hardware") |

Configuration parameters |

------------------------ |
|
|
|
|
|
|
|
- ``skip_timeout_commit`` |
|
|
|
|
|
|
|
We want skip_timeout_commit=false when there is economics on the line because |
|
|
|
proposers should wait to hear for more votes. But if you don't care about that |
|
|
|
and want the fastest consensus, you can skip it. So we will keep it false for |
|
|
|
the hub and as default, but for enterprise applications, no problem to set to |
|
|
|
true. |
