TenderSeed

This is a fork of polychainlabs tenderseed repo

A lightweight seed node for a Tendermint p2p network.

Seed nodes maintain an address book of active peers on a Tendermint p2p network. New nodes can dial known seeds and request lists of active peers for establishing p2p connections.

This project implements a lightweight seed node. The lightweight node maintains an address book of active peers, but does not relay or store blocks or transactions.

Familiarity with Tendermint network operation is a pre-requisite to understanding how to use TenderSeed.

Quickstart

Build with make and start a seed node with the start command.

This will run with defaults and seed/crawl Osmosis

tenderseed start

This will seed/crawl cosmoshub-4

tenderseed -seeds=bf8328b66dceb4987e5cd94430af66045e59899f@public-seed.cosmos.vitwit.com:26656,cfd785a4224c7940e9a10f6c1ab24c343e923bec@164.68.107.188:26656,d72b3011ed46d783e369fdf8ae2055b99a1e5074@173.249.50.25:26656,ba3bacc714817218562f743178228f23678b2873@public-seed-node.cosmoshub.certus.one:26656,3c7cad4154967a294b3ba1cc752e40e8779640ad@84.201.128.115:26656,366ac852255c3ac8de17e11ae9ec814b8c68bddb@51.15.94.196:26656 -chain-id cosmoshub-4 start

To view your node id (you will need this for other nodes to connect), invoke the show-node-id command.

The first run of Tenderseed will generate a node key if one does not exist.

$ tenderseed show-node-id

Home Dir

All TenderSeed configuration and address book data is stored in the TenderSeed home directory.

The default path is $HOME/.tenderseed but you can specify your own path via the --home command line argument.

tenderseed --home /some/path/to/home/dir

The default configuration stores the node key in a config folder and the address book in a data folder within the home folder.

Configuration

TenderSeed is configured by a toml config file found in the tenderseed home dir as config/config.toml

The seed is configured via a toml config file. The default configuration file is shown below.

A first run of Tenderseed will generate a default configuration if one does not exist.

# path to address book (relative to tendermint-seed home directory or an absolute path)
addr_book_file = "data/addrbook.json"

# Set true for strict routability rules
# Set false for private or local networks
addr_book_strict = true

# network identifier (todo move to cli flag argument? keeps the config network agnostic)
chain_id = "some-chain-id"

# Address to listen for incoming connections
laddr = "tcp://0.0.0.0:26656"

# logging level to filter output ("info", "debug", "error" or "none")
log_level = "info"

# maximum number of inbound connections
max_num_inbound_peers = 1000

# maximum number of outbound connections
max_num_outbound_peers = 10

# maximum size of a message packet payload, in bytes
max_packet_msg_payload_size = 1024

# path to node_key (relative to tendermint-seed home directory or an absolute path)
node_key_file = "config/node_key.json"

# seed nodes we can use to discover peers
seeds = ""
