frequencychain/instant-seal-node repository overview

⁠Frequency Collator Node in Local Only Sealing Mode

⁠Deprecation Note

This image has been deprecated and will be removed in a future Frequency release. The new image, frequencychain/standalone-node⁠, replaces it. Current usage patterns for this image are fully supported by the new image, as well as additional enhancements.

⁠Description

Runs just one collator node that will not connect to any other nodes. Defaults to running in instant sealing mode where a block will be triggered when a transaction enters the validated transaction pool. A "collator node" is a Frequency parachain node that is actively collating (aka forming blocks to submit to the relay chain, although in this case without a relay chain).

⁠Quick Run

docker run --rm -p 9944:9944 -p 30333:30333 frequencychain/instant-seal-node:<version.tag>

⁠Trigger Block Manually

If running in manual sealing mode or to form empty blocks in instant sealing mode, the engine_createBlock RPC can be used:

curl http://localhost:9944 -H "Content-Type:application/json;charset=utf-8" -d   '{ \
    "jsonrpc":"2.0", \
    "id":1, \
    "method":"engine_createBlock", \
    "params": [true, true] \
    }'

⁠Default Arguments

⁠Run

Note: Docker --rm removes the volume when stopped.

docker run --rm -p 9944:9944 -p 30333:30333 frequencychain/instant-seal-node:<version.tag>

⁠Overriding Arguments

⁠Run

docker run --rm -p 9944:9944 -p 30333:30333 frequencychain/instant-seal-node:<version.tag> -- --manual-seal
