Note: Public parquet files are available to everyone. Access to EthPandaOps Clickhouse is restricted. If you need access please reach out to us at ethpandaops at ethereum.org.
Check out the visual representation of the extraction process.
For a detailed description of the data schema, please refer to the Schema Documentation.
Public data is available in the form of Apache Parquet files. You can use any tool that supports the Apache Parquet format to query the data.
If you have access to EthPandaOps Clickhouse you can query the data directly. Skip ahead to Using EthPandaOps Clickhouse.
There's a few ways to get started with the data. First install the dependencies:
- Install docker
- Verify the installation by running the following command:
docker version
There are three options to get started with the data, all of them using Clickhouse.
-
Option 1: Setup your own Clickhouse server and import the data.
Recommended for most use cases.
Great for larger, repeated queries or when you want to query the data in a more complex way.
-
Option 2: Query the public parquet files directly.
Great for small queries one-off queriesor when you don't want to setup your own Clickhouse server.
-
Option 3: Use EthPandaOps Clickhouse.
Great for quick and easy queries. No setup required but access is limited.
Running your own Clickhouse cluster is recommended for most use cases. This process will walk you through the steps of setting up a cluster with the Xatu Clickhouse migrations and importing the data straight from the public parquet files.
-
Clone the Xatu repo
Xatu contains a docker compose file to run a Clickhouse cluster locally. This server will automatically have the correct schema migrations applied.Steps:
- Clone the Xatu repo
git clone https://github.com/ethpandaops/xatu.git; cd xatu
- Start the Xatu clickhouse stack
docker compose --profile clickhouse up --detach
- Verify the Clickhouse server is running and migrations are applied
This should show you the tables that are available in the default database. e.g.
docker run --rm -it --net host clickhouse/clickhouse-server clickhouse client --query "SHOW TABLES FROM default" | grep -v local
... beacon_api_eth_v1_beacon_committee beacon_api_eth_v1_events_attestation beacon_api_eth_v1_events_blob_sidecar ...
- Clone the Xatu repo
-
Load data into Clickhouse
Our Clickhouse cluster is running but has no data! Let's import some data.
Steps:
- Clone the Xatu-data repository
cd; git clone https://github.com/ethpandaops/xatu-data.git cd xatu-data;
- Install clickhouse client
curl https://clickhouse.com/ | sh
- Import the data into Clickhouse
This will import the data for the
./import-clickhouse.sh mainnet default beacon_api_eth_v1_events_block 2024-03-20 2024-03-27
default.beacon_api_eth_v1_events_block
table in mainnet from the 20th of March 2024 to the 27th of March 2024. - Verify the data import
This query will show you the count of events per day.
docker run --rm -it --net host \ clickhouse/clickhouse-server clickhouse client -q "SELECT toStartOfDay(slot_start_date_time) AS day, COUNT(*) FROM default.beacon_api_eth_v1_events_block GROUP BY day FORMAT Pretty"
- Clone the Xatu-data repository
-
Query Parquet Files Directly
Alternatively, you can query the parquet files directly without importing. This is useful if you only need to query a small subset of the data.
Steps:
- Query the first 10 rows of the beacon_api_eth_v1_events_block table for 2024-03-20
# date based partitioned tables clickhouse local --query="SELECT * FROM url('https://data.ethpandaops.io/xatu/mainnet/databases/default/beacon_api_eth_v1_events_block/2024/3/20.parquet', 'Parquet') LIMIT 10 FORMAT Pretty"
- Query the first 10 rows of the canonical_execution_block table for chunk
20000000.parquet
(block numbers between20000000
and20000999
)# integer based partitioned tables clickhouse local --query="SELECT * FROM url('https://data.ethpandaops.io/xatu/mainnet/databases/default/canonical_execution_block/1000/20000000.parquet', 'Parquet') LIMIT 10 FORMAT Pretty"
- Use globs to query multiple files, e.g., 15th to 20th March or between block
20000000
and20010000
# date based partitioned tables clickhouse local --query="SELECT COUNT(*) FROM url('https://data.ethpandaops.io/xatu/mainnet/databases/default/beacon_api_eth_v1_events_block/2024/3/{15..20}.parquet', 'Parquet') FORMAT Pretty" # integer based partitioned tables clickhouse local --query="SELECT COUNT(*) FROM url('https://data.ethpandaops.io/xatu/mainnet/databases/default/canonical_execution_block/1000/{20000..20010}000.parquet', 'Parquet') LIMIT 10 FORMAT Pretty"
- Query the first 10 rows of the beacon_api_eth_v1_events_block table for 2024-03-20
The EthPandaOps Clickhouse cluster already has the data loaded and the schema migrations applied. You can query the data directly. If you need access please reach out to us at ethpandaops at ethereum.org. Access is limited.
-
Query the data
Steps:
-
Setup your credentials
export CLICKHOUSE_USER=YOUR_USERNAME export CLICKHOUSE_PASSWORD=YOUR_PASSWORD
-
Execute a query
echo """ SELECT * FROM default.beacon_api_eth_v1_events_block FINAL WHERE slot_start_date_time >= NOW() - INTERVAL '1 HOUR' LIMIT 3 FORMAT Pretty """ | curl "https://clickhouse.xatu.ethpandaops.io" -u "$CLICKHOUSE_USER:$CLICKHOUSE_PASSWORD" --data-binary @-
-
Querying the public parquet files is a great way to get started with the data. We recommend you don't do this for larger queries or queries that you'll run again.
Examples:
- Count the number of block events per consensus client for the 20th of March 2024 on Mainnet
docker run --rm -it clickhouse/clickhouse-server clickhouse local --query="
SELECT
count(*), meta_consensus_implementation
FROM url('https://data.ethpandaops.io/xatu/mainnet/databases/default/beacon_api_eth_v1_events_block/2024/3/20.parquet', 'Parquet')
GROUP BY meta_consensus_implementation
FORMAT Pretty
"
- Show the top 5 block builders by block numbers between 20000000 and 20010999
docker run --rm -it clickhouse/clickhouse-server clickhouse local --query="
SELECT
count(*),
extra_data_string
FROM url('https://data.ethpandaops.io/xatu/mainnet/databases/default/canonical_execution_block/1000/{20000..20010}000.parquet', 'Parquet')
WHERE
block_number BETWEEN 20000000 AND 20010000
GROUP BY extra_data_string
ORDER BY count(*) DESC
LIMIT 5
FORMAT Pretty
"
Once your Clickhouse server is setup and the data is imported, you can query the data.

There are some examples for both Parquet and Clickhouse and SQLAlchemy in the examples/parquet and examples/clickhouse directories respectively.
We're excited to announce that we are opening up the Xatu data collection pipeline to the Ethereum community! This initiative enables community members to contribute valuable data to the Xatu dataset.
As discussions regarding the potential increase in maximum blob count continue we hope to shed light on the perspective of Ethereum's most crucial participants - home stakers.
Summary:
- Privacy focused. Multiple privacy levels that allow contributors to only disclose data they're comfortable with
- Initially restricted to known community members
- Data is published daily by the EthPandaOps team
Data is collected by running a Beacon node and the xatu sentry
sidecar. The data is then sent to a pipeline that we run, which further anonymizes and redacts the data.

Once we recieve the event, we do some additional processing to get the server metadata. The data that is added to the event is configurable per-user and allows users to only disclose data they're comfortable with. Geo location data is very useful for understanding how data is propagated through the network, but is not required.

fields are ALWAYS redacted.
Privacy is a top priority for us. We have created privacy groups to allow users to only disclose data they're comfortable with.

Contributing to the Xatu dataset is currently restricted to known community members. We have plans to open this up to the public in the future, but for now, we want to ensure that the data remains high quality and relevant to the home staker community (read: we need to make sure our pipeline can handle the increased load 😂)
If you'd like to contribute to the Xatu dataset, please apply for access here
Once you've been granted access, you'll receive instructions on how exactly to run xatu sentry
and start contributing to the dataset.
If you're already running a beacon node, running xatu sentry
is as simple as running a docker container on your node. For example:
docker run -d \
--name xatu-sentry \
--restart unless-stopped \
--cpus="0.5" \
--memory="1g" \
--read-only \
ethpandaops/xatu:latest sentry \
--preset ethpandaops \
--beacon-node-url=http://localhost:5052 \
--output-authorization=REDACTED
You can download the binary from our GitHub Releases page or use the install script.
Once you have the xatu
binary, you can run it with the following command:
xatu sentry \
--preset ethpandaops \
--beacon-node-url=http://localhost:5052 \
--output-authorization=REDACTED
