Run the full node..

Synopsis

Run the full node application with Tendermint in or out of process. By default, the application will run with Tendermint in process.

To learn how to run a full node, visit the Full node guide.

Pruning options can be provided via the --pruning flag or alternatively with --pruning-keep-recent, pruning-keep-every, and pruning-interval together.

For --pruning the options are as follows:

• default: the last 100 states are kept in addition to every 500th state; pruning at 10 block intervals.
• nothing: all historic states will be saved, nothing will be deleted (i.e. archiving node).
• everything: all saved states will be deleted, storing only the current and previous state; pruning at 10 block intervals.
• custom: allow pruning options to be manually specified through pruning-keep-recent, pruning-keep-every, and pruning-interval.

Node halting configurations exist in the form of two flags: --halt-height and --halt-time. During the ABCI Commit phase, the node will check if the current block height is greater than or equal to the halt-height or if the current block time is greater than or equal to the halt-time. If so, the node will attempt to gracefully shut down and the block will not be committed. In addition, the node will not be able to commit subsequent blocks.

For profiling and benchmarking purposes, CPU profiling can be enabled via the --cpu-profile flag which accepts a path for the resulting prof file.

The node may be started in a query only mode where only the gRPC and JSON HTTP API services are enabled via the grpc-only flag. In this mode, Tendermint is bypassed and can be used when legacy queries are needed after an on-chain upgrade is performed. Note: when enabled, gRPC will also be automatically enabled.
