We have released a new version of Bor and Heimdall - v0.3.0 with an incremented minor version. As explained in the previous post, we have added a new CLI in Bor and have also changed the way Bor and Heimdall are deployed to follow DevOps best practices and make it easier to manage the processes. This upgrade is backwards incompatible. Please ensure that all Mumbai nodes are upgraded soon, before the release of the next version v0.3.1 that will contain a hardfork which is scheduled to kick in on 7th Dec 2022 (tentative).
Important Note: For our next releases, v0.3.1 and onward, upgrading to version 0.3.0 is necessary.
Please read the major changes in Bor and Heimdall from deployment perspective below before upgrading your node.
Deployment Changes
Changes in Bor:
- Provide a new approach to install bor binary with a shell script: GitHub - maticnetwork/install.
- Recommended default bor home is changed from
~/.borto/var/lib/bor. -
bor/start.shwill be retired. We recommend moving flags fromstart.shto/var/lib/bor/config.toml, which will be the single config file for all bor configurations. Example config toml files could be found in GitHub - maticnetwork/launch: Matic network mainnet v1 launch. - A new user named
borwill be created during package installation if it doesn’t exist. This user will be running bor service. - Move
bor.servicefile from/etc/systemd/systemto/lib/systemd/system - CLI flag changes. For validators who wants to continue setting bor configs through CLI, see appendix for detailed changes.
- Bor profiles can be used with new hosts only, please note existing installations will not be able to take advantages of the profiles.
- Bor packaging installation is now simplified to
sudo dpkg -i bor-$version-$arch.deb - Bor profile installation for new hosts is accomplished by running
sudo dpkg -i bor-$network-$nodetype-config_$version-$arch.deb
Changes in Heimdall:
- Provide a new approach to install heimdall binary with a shell script: GitHub - maticnetwork/install.
- Remove
bridgebinary and add it as a subcommand inheimdalld. - Remove
heimdalld-rest-server.serviceandheimdalld-bridge.service, and moveheimdalld.servicefile from/etc/systemd/systemto/lib/systemd/system. - Change default heimdall home from
~/.heimdalldto/var/lib/heimdall. - A new user named
heimdallwill be created during package installation if it doesn’t exist. This user will be running heimdall service. - Heimdall packaging installation is now simplified to
sudo dpkg -i heimdalld-$version-$arch.deb - Heimdall profile installation for new hosts is accomplished by running
sudo dpkg -i heimdalld-$network-$nodetype-config_$version-$arch.deb
Note: Please find more details about CLI and binary changes in the Appendix.
Upgrade/Migration Instructions
Steps to Migrate to the new version:
-
Stop all the services
sudo service bor stop sudo service heimdalld stop sudo service heimdalld-bridge stop sudo service heimdalld-rest-server stop -
Install Bor with a version tag, network name (mainnet or mumbai), and node type (sentry, validator, or archive).
# Replace the network and node type curl -L https://raw.githubusercontent.com/maticnetwork/install/main/bor.sh | bash -s -- v0.3.0-beta <network> <node_type> -
Install Heimdall with a version tag, network name (mainnet or mumbai), and node type (sentry, validator, or archive).
# Replace the network and node type curl -L https://raw.githubusercontent.com/maticnetwork/install/main/heimdall.sh | bash -s -- v0.3.0-beta <network> <node_type> -
Set the old bor home directory path, and export it. This will be used, whenever needed, moving forward.
# Note: in this case, the old bor directory is `~/.bor`. # Modify it according to your setup. export OLD_BOR_HOME=~/.bor -
Link the Bor Data folder and change the owner of files to user
bor, which is created in step 2# Note: The commands given below are under the assumption that # $OLD_BOR_HOME contains the correct bor home directory (BOR_DIR). # Modify it according to your setup as mentioned in the previous point. sudo chown -R bor $OLD_BOR_HOME sudo ln -nfs $OLD_BOR_HOME/data /var/lib/bor/data sudo ln -nfs $OLD_BOR_HOME/keystore /var/lib/bor/keystore # only for validator node sudo ln -nfs $OLD_BOR_HOME/password.txt /var/lib/bor/password.txt # only for validator node sudo ln -nfs $OLD_BOR_HOME/address.txt /var/lib/bor/address.txt # only for validator node sudo chown bor /var/lib/bor -
Set the old heimdall home directory path, and export it. This will be used, whenever needed, moving forward.
# Note: in this case, the old heimdall directory is `~/.heimdalld`. # Modify it according to your setup. export OLD_HEIMDALL_HOME=~/.heimdalld -
Link the Heimdall data folder and change the owner of files to user
heimdall, which is created in step 3# Note: The commands given below are under the assumption that # $OLD_HEIMDALL_HOME contains the correct heimdalld home directory. # Modify it according to your setup as mentioned in the previous point. sudo chown -R heimdall $OLD_HEIMDALL_HOME sudo rm -rf /var/lib/heimdall sudo ln -nfs $OLD_HEIMDALL_HOME /var/lib/heimdall sudo chown heimdall /var/lib/heimdall -

Migrating to config.toml from start.sh:
To migrate the configuration/flags from
start.shto aconfig.toml, you can use a utility script as described below.
Example usage:$ git clone https://github.com/maticnetwork/bor.git # If not already cloned $ cd bor $ git fetch $ git checkout tags/v0.3.0-beta $ make bor $ cd scripts # Note: Running this command will output a config.toml which will have # values populated from the start.sh. Also, the script demands # for path to start.sh, validator address (if required) and path # to static-nodes.json if not found in the default location. $ BOR_DIR=/var/lib/bor ./getconfig.sh ... * Path to start.sh: /home/ubuntu/node/bor/start.sh * Your validator address (e.g. 0xca67a8D767e45056DC92384b488E9Af654d78DE2), or press Enter to skip if running a sentry node: 0xca67a8D767e45056DC92384b488E9Af654d78DE2 * You dont have '~/.bor/data/bor/static-nodes.json' file. If you want to use static nodes, enter the path to 'static-nodes.json' here (press Enter to skip): /home/ubuntu/my/path/static-nodes.json Thank you, your inputs are: Path to start.sh: /home/ubuntu/node/bor/start.sh Address: 0xca67a8D767e45056DC92384b488E9Af654d78DE2 Path to the config file: **/home/ubuntu/node/bor-start-config.toml** ... # Note: We're considering /home/ubuntu as our home directory. Please # update the commands to use your home directory before proceeding. # Copy the newly created file from the output above # (Path to the config file) to /var/lib/bor/config.toml $ sudo cp **/home/ubuntu/node/bor-start-config.toml** /var/lib/bor/config.toml $ sudo chown bor /var/lib/bor/config.toml -
With
v0.3.0, we are updating the gas limit in Mumbai network to 30M from 20M to match the value in Mainnet. For this,miner.gaslimitfield needs to be updated in the config file. Open the file/var/lib/bor/config.tomlin your favourite text editor and edit the value forgaslimitunderminersection:[miner] ... gaslimit = 30000000 ... -
For better monitoring of overall network and conditions of node, we have hosted ethstats dashboard (https://bor-mumbai.vitwit.com/). We would advise all the nodes to use the public endpoint for sending data (if you’re not sending it to some other internal endpoint). The endpoint can be configured in the config file itself and is of the format:
<node_identifier>:[email protected]:3000. We would encourage you to use a non-existing and understandable identifier. This dashboard would also help us in alerting incase the nodes are not working properly (e.g. if they’re constantly out of sync).Open the file
/var/lib/bor/config.tomlin your favourite text editor and edit the value forethstats:ethstats = "<node_identifier>:[email protected]:3000" -
Ensure that all the values have been populated correctly in bor config file
/var/lib/bor/config.toml. If you want to change any config options, you can edit the file.For your reference, an example config for mumbai can be found here. All Config flags could be found here and documentation for each bor subcommand can be found here.
If you are not migrating from an old start.sh, the default values populated should work out of the box for a sentry node. For validator nodes, you might want to update some of the flags like:
etherbase,unlock,password,keystore,maxpeers,static-nodes,ethstats, and additional telemetry configuration (from older start.sh based config). -
Restart system processes:
sudo systemctl daemon-reload sudo systemctl start heimdalld.service journalctl -u heimdalld.service -f # Monitor heimdall service sudo systemctl restart telemetry.service sudo systemctl start bor journalctl -u bor.service -f # Monitor bor service

Appendix
Bor Detailed Change log
- In v0.2.x,
borandbootnodeare two separate binaries. In v0.3.0,bootnodewill become a subcommand ofbor. -
bor initis removed in v0.3.0. Instead, on starting,borwill automatically initialize a bor home directory if not found. -
bor’s default behavior (running bor client) is moved tobor serveras a subcommand. -
GRPC: On starting bor using theserversubcommand, it will start a GRPC server on a separate port which will be used for cli related communication. Here, the user using the cli, acts as a client and interacts with the node using GRPC. It is used for operations like adding and removing peers, getting status of node (sync status, forks, chain head, etc), getting debug and pprof traces, etc. - Validator must provide its public address to flag
--miner.etherbasein order to mint blocks. - The format of toml passed to
--configis changed. Notice that, in v0.2.x, only P2P related info like static or trusted nodes were mentioned in the toml file. With v0.3.x, you can pass the whole cli config using this flag. For more details and examples, see https://github.com/maticnetwork/bor/blob/develop/docs/config.md. -
--networkidis replaced by--chain, whose value is eithermainnetormumbai. The flag also accepts the path to a custom genesis file, e.g.--chain path/to/custom_genesis.json. -
--verbosityis replaced by--log-leveland instead of numeric values, string denoting the type of log should be passed. -
--whitelistis now changed to--requiredblocks - pprof options are merged to a new component,
grpc. e.g.--pprof.addr 0.0.0.0and--pprof.port 1234should be passed as one argument to flag--grpc.addr 0.0.0.0:1234. If not set, default value will be0.0.0.0:3131. -
--metrics.addrand--metrics.portare merged to--metrics.prometheus-addr. e.g.--metrics.addr 0.0.0.0and--metics.port 1234should be passed as one argument to flag--metrics.prometheus-addr 0.0.0.0:1234. Notice that, in v0.2.x,--metrics.addrand--metrics.port, if not explicitly set, the metrics will be exported onpprof.addr:pprof.port. If no flag is provided, the prometheus endpoint is registered on a default host and port. - A new flag named
disable-bor-walletis introduced which disables the personal wallet endpoints in the node. This prevents misuse of the endpoints if exposed. It will only register and use the key-store for mining blocks (if mining is enabled through--unlockand--miner.etherbase). It’s set totrueby default. - borTraceEnabled added in TraceConfig. When set true, it will return state-sync traces for a block if present. Usage :
debug.traceBlockByNumber("0x20FE900",{"borTraceEnabled": true}) - The
miner.gaslimitvalue has been updated for mumbai nodes from 20M to 30M.
Heimdall Detailed Change Log
- In v0.2.x,
heimdalldandbridgeare two separate binaries. In v0.3.0,bridgewill become a subcommand ofheimdalld. - In v0.2.x,
heimdalld,bridge, andrest-serverare run in three different processes. In v0.3.0, they could be launched together in a single process with one CLI command. - In v0.3.0, building different
heimdalldbinary for different network is no longer needed.heimdalldbinary will support both mainnet and mumbai testnet. - Log level of heimdall is changed from a single letter to a full word. Example:
BeforeI[2022-09-22|19:11:42.896] Served RPC HTTP response
AfterINFO [2022-09-22|19:11:42.896] Served RPC HTTP response - heimdall no longer needs a genesis file. Instead, the genesis file will be embedded in the binary of heimdalld.
- Provide possibility to log in
jsonformat by setting the paramlogs_type = "json"
in theheimdall-config.tomlfile. - Change
TaskDelayBetweenEachValfrom 24s to 10s to reduceStateSyncedevent delays - Log elapsed time for each method involved in the
StateSyncedflow. - Add benchmark tests for the most time consuming functions involved in the
StateSyncedflow.
