Public Chain

In the master branch there is a code with functions that is under development. The latest release for each network can be found in the Releases section, you can switch to the corresponding tag and build the application.

To build the node localy, run

sbt build

It will produce lto-public-all-*.jar in the target folder.

For further information please read the LTO Network documentation.

Docker

Build

docker build . -t ltonetwork/public-node

Run

The simplest way to run a container:

docker run -it ltonetwork/public-node

For MAINNET:

docker run -p 6869:6869 -p 6868:6868 -e LTO_HEAP_SIZE=2g -e LTO_ENABLE_REST_API -v YOUR_LOCAL_PATH_HERE:/lto ltonetwork/public-node    

For TESTNET:

docker run -p 6869:6869 -p 6863:6863 -e LTO_NETWORK=TESTNET -e LTO_HEAP_SIZE=2g -v YOUR_LOCAL_PATH_HERE:/lto ltonetwork/public-node

You can run the container with these environment variables:

Env variable	Description
LTO_WALLET_SEED	Plain text seed for node wallet. Container converts it to base58.
LTO_WALLET_SEED_BASE58	Base58 encoded seed. (Supersedes LTO_WALLET_SEED)
LTO_WALLET_PASSWORD	Password for wallet file.
LTO_API_KEY	ApiKey used for the rest api authentication
LTO_NETWORK	Available values are MAINNET, TESTNET and CUSTOM. (Default: MAINNET)
LTO_LOG_LEVEL	Node logging level, available values: OFF, ERROR, WARN, INFO, DEBUG, TRACE.
LTO_HEAP_SIZE	Java Heap Size limit in -X Command-line Options notation (-Xms=[your value]). More details here
LTO_CONFIG_FILE	Path to your LTO Configuration file.
LTO_DECLARED_ADDRESS	String with IP address and port to send as external address during handshake. Could be set automatically if UPnP is enabled. If declared-address is set, which is the common scenario for nodes running in the cloud, the node will just listen to incoming connections on bind-address:port and broadcast its declared-address to its peers.
LTO_NODE_NAME	Node name used in the handshake when connecting to other nodes
LTO_ENABLE_REST_API	To enable the REST API. (For MAINNET default is false for TESTNET default is true)
LTO_ENABLE_MINING	To enable PoS mining (default is true)
LTO_FEATURES	Features you wish to vote. E.g. set to 4 to start voting for the Smart Accounts feature. You can also vote for multiple features at by comma seperating them (e.g. 4,5)

Note: All variables are optional.

The following variables can be used to control fee voting:

Env variable	Description
COINMARKETCAP_API_KEY	CoinMarketCap API key. When supplied, the script will query CoinMarketCap in addition to CoinGecko to prevent voting based on incorrect data.
LTO_FEE_TARGET	Value to determine how to vote. See Fee Prices.

Debian

To package the build as debian package, run

sbt packageAll -Dnetwork=mainnet                            # Mainnet
sbt packageAll -Dnetwork=testnet -DpackageName=lto-testnet  # Testnet

Installation

The .deb package can be downloaded from the GitHub release page.

wget https://github.com/ltonetwork/lto-public-chain/releases/download/v1.6.3/lto_1.6.3_all.deb 
dpkg -i lto_1.6.3_all.deb

Fee vote

The debian package installs a python script named lto-fee-vote. Please participate in Fee voting by calling this script through a cronjob once an hour.

0 * * * *  root  /usr/bin/lto-fee-vote http://localhost:6869 /var/lib/lto/lto/fee-vote

For testnet use the path /var/lib/lto-testnet/lto/fee-vote instead.

If you choose not to enable the REST API on your node, you can query https://nodes.lto.network instead of http://localhost:6869.
