DataLayer CLI

This page includes a comprehensive list of Chia's Command Line Interface commands for interacting with the DataLayer.

We also have documented the RPC API for interacting with the DataLayer.

The relevant DataLayer commands can be found by running chia data:

(venv) $ chia data -h

Commands that modify the blockchain include an optional fee. This fee can be specified in two ways:

The -m / --fee parameter can be specified explicitly in the command, as several of the examples in this document show
If the fee option is not explicitly specified, then the data_layer:fee setting in ~/.chia/mainnet/config/config.yaml will be used. By default, this is set to 1 billion mojos (0.001 XCH)
If neither of these options is set, then no fee will be used

For commands that change the state of the DataLayer singleton (ie all on-chain commands), you will need to wait for confirmation before running another command. If you run a command before the previous transaction has been confirmed, you will receive this error: Request failed: {'error': 'Already have a pending root waiting for confirmation.', 'success': False}

The commands in this document will work with or without the = symbol. Additionally, hashes may or may not be prefixed with 0x.

Reference

`add_mirror`

Functionality: Add a new mirror from a local or remote data store. Triggers a Chia transaction

Usage: chia data add_mirror [OPTIONS]

Options:

Short Command	Long Command	Type	Required	Description
-i	--id	TEXT	True	The hexadecimal ID of the store to mirror
-a	--amount	INTEGER	True	The amount (in mojos) to spend to create the mirror. In theory, mirrors with a higher `amount` will be prioritized. Minimum `amount` is 0
-u	--url	TEXT	False	A URL where the mirror will reside. Can be repeated to add multiple URLs in the same command
-m	--fee	TEXT	False	Set the fees for the transaction, in XCH
-dp	--data-rpc-port	INTEGER	False	Set the port where the DataLayer is hosting the RPC interface. See rpc_port under wallet in config.yaml
-f	--fingerprint	INTEGER	False	Fingerprint of the wallet to use
-h	--help	None	False	Show a help message and exit

Example

Create one mirror with multiple URLs:

chia data add_mirror -i 1a119374fc7d7055d3419fdcd7f93065f28a1e4acacdf9c73b933b27b685550f -a 1000 -u http://www.example.com:8575 -u http://www.example2.com:8575

Response:

None

`add_missing_files`

Functionality: Use the database to restore all files for one or more local data stores

Usage: chia data add_missing_files [OPTIONS]

Options:

-i	--ids	TEXT	True	The hexadecimal store id(s)
-o	--override	None	False	If set, will overwrite files that already exist (default: not set)
-n	--no-override	None	False	If set, will not overwrite files that already exist (default: set)
-d	--directory	TEXT	False	If specified, use a non-default directory to write the files (default: `~/.chia/mainnet/data_layer/db/server_files_location_<network>`)
-dp	--data-rpc-port	INTEGER	False	Set the port where the DataLayer is hosting the RPC interface. See rpc_port under data_layer in config.yaml
-f	--fingerprint	INTEGER	False	Fingerprint of the wallet to use
-h	--help	None	False	Show a help message and exit

Intentionally move the files and create an empty folder. This will simulate file corruption:

mv ~/.chia/mainnet/data_layer/db/server_files_location_testnet10 ~/.chia/mainnet/data_layer/db/server_files_location_testnet10_bak
mkdir ~/.chia/mainnet/data_layer/db/server_files_location_testnet10/

Next, restore the files:

chia data add_missing_files

Response:

None

Finally, verify that the files have been restored:

ls ~/.chia/mainnet/data_layer/db/server_files_location_testnet10/

`unsubscribe`

Functionality: Unsubscribe from a store ID

Usage: chia data unsubscribe [OPTIONS]

Options:

Short Command	Long Command	Type	Required	Description
-store	--id	TEXT	True	The hexadecimal ID of the store to which you would like to unsubscribe
-dp	--data-rpc-port	INTEGER	False	Set the port where the DataLayer is hosting the RPC interface. See rpc_port under wallet in config.yaml

信息

The unsubscribe command may or may not delete any data, depending on which version of Chia you are running:

Prior to version 2.1, the command did not delete the .dat files, nor did it delete from the database.
As of version 2.1, the command deletes the .dat files, but does not delete from the database.
In a future release, the command will also delete from the database.

Example:

Example

chia data unsubscribe -store 8f6ed792bbbf5216f8e55064793f74ce01286b9c1d542cc4a357cf7f8712df1d

`update_data_store`

Functionality: Update a data store with a given changelist. Triggers a Chia transaction

Usage: chia data update_data_store [OPTIONS]

Options:

Short Command	Long Command	Type	Required	Description
-store	--id	TEXT	True	The hexadecimal store ID
-d	--changelist	TEXT	True	A JSON object representing the changelist
-dp	--data-rpc-port	INTEGER	False	Set the port where the DataLayer is hosting the RPC interface. See rpc_port under wallet in config.yaml
-m	--fee	TEXT	False	Set the fees for the transaction, in XCH
-f	--fingerprint	INTEGER	False	Set the fingerprint to specify which wallet to use
	--submit	None	False	Set to submit the result on chain [Default: don't submit]
	--no-submit	None	False	Set to explicitly specify not to submit the result on chain [Default: don't submit]
-h	--help	None	False	Show a help message and exit

A few notes on the -d / --changelist option:

The entire list must be formatted as a JSON array
There are two actions allowed: insert and delete
insert requires key and value flags
delete requires a key flag only
Keys and values must be written in hex format. Values can be derived from text or binary.
Labels, keys and values must all be enclosed in double quotes
Multiple inserts and deletes are allowed
The size of a single value flag is limited to 100 MiB. However, adding anything close to that size has not been tested and could produce unexpected results.
On Windows, you must escape the double quotes in the JSON array with backslashes. See below for an example. This is not required on MacOS or Linux.

The following examples will show the basic functionality of this command.

Example 1 -- Insert a single key/value pair

`verify_proof`

Functionality: Verifies a merkle proof of inclusion

Usage: chia data verify_proof [OPTIONS]

Options:

Short Command	Long Command	Type	Required	Description
-p	--proof	TEXT	True	Proof to validate in JSON format
-dp	--data-rpc-port	INTEGER	False	Set the port where the DataLayer is hosting the RPC interface. See rpc_port under wallet in config.yaml
-f	--fingerprint	INTEGER	False	Set the fingerprint to specify which wallet to use
-h	--help	None	False	Show a help message and exit

Notes about this command:

It only needs to perform a single lookup of the on-chain root.
It doesn't need to have synced any of the data, or be subscribed to the data store.
To keep the proofs smaller, only the clvm hash of the key and value are included in the proof, and not the actual key or value. (A clvm hash is just a sha256 hash of the data prepended with 0x01.)
Datalayer uses CLVM hashes for ease of verification in CLVM, although for this specific use case, there is no on-chain validation happening.
When using this command, pay attention to the current_root value in the returned JSON.
- If current_root is True, this data chains to the current published root, and so if you synced the data, you can be sure it would be there.
- If current_root is False, the root has moved from the time the proof was generated. You cannot make any assumptions in this case about whether the data is in fact in the datastore or not since the root has changed, therefore the data might have changed. It is up to the caller to determine how to treat this case; one possible action would be to obtain a new proof.

The proof to validate requires several fields:

coin_id
inner_puzzle_hash
store_proofs
- proofs
  - key_clvm_hash
  - value_clvm_hash
  - node_hash
  - layers

Each of these fields is output with the get_proof command. For more examples, see chia-blockchain PR #16845.
