eth-statediff-service
standalone statediffing service on top of LevelDB
Purpose:
Stand up a statediffing service directly on top of a go-ethereum LevelDB instance. This service can serve historical state data over the same rpc interface as statediffing geth without needing to run a full node.
Setup
Build the binary:
make build
Configuration
An example config file:
[leveldb]

Local Setup
-
Create a chain config file
chain.json
according to chain config in genesis json file used by local geth.Example:
{ "chainId": 41337, "homesteadBlock": 0, "eip150Block": 0, "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000", "eip155Block": 0, "eip158Block": 0, "byzantiumBlock": 0, "constantinopleBlock": 0, "petersburgBlock": 0, "istanbulBlock": 0, "clique": { "period": 5, "epoch": 30000 } }
Provide the path to the above file in the config.
Usage
- Create / update the config file (refer to example config above).
serve
-
To serve the statediff RPC API:
./eth-statediff-service serve --config=<config path>
Example:
./eth-statediff-service serve --config environments/config.toml
-
Available RPC methods:
statediff_stateTrieAt()
statediff_streamCodeAndCodeHash()
statediff_stateDiffAt()
statediff_writeStateDiffAt()
statediff_writeStateDiffsInRange()
Example:
curl -X POST -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"statediff_writeStateDiffsInRange","params":['"$BEGIN"', '"$END"', {"intermediateStateNodes":true,"intermediateStorageNodes":true,"includeBlock":true,"includeReceipts":true,"includeTD":true,"includeCode":true}],"id":1}' "$HOST":"$PORT"
-
Prerun:
- The process can be configured locally with sets of ranges to process as a "prerun" to processing directed by the server endpoints.
- This is done by turning "prerun" on in the config (
statediff.prerun = true
) and defining ranges and params in theprerun
section of the config. - Set the range using
prerun.start
andprerun.stop
. Useprerun.ranges
if prerun on more than one range is required.
-
NOTE: Currently,
params.includeTD
must be set to / passed astrue
.
Monitoring
- Enable metrics using config parameters
prom.metrics
andprom.http
. eth-statediff-service
exposes following prometheus metrics at/metrics
endpoint:ranges_queued
: Number of range requests currently queued.loaded_height
: The last block that was loaded for processing.processed_height
: The last block that was processed.stats.t_block_load
: Block loading time.stats.t_block_processing
: Block (header, uncles, txs, rcts, tx trie, rct trie) processing time.stats.t_state_processing
: State (state trie, storage tries, and code) processing time.stats.t_postgres_tx_commit
: Postgres tx commit time.http.count
: HTTP request count.http.duration
: HTTP request duration.ipc.count
: Unix socket connection count.
Tests
-
Run unit tests:
make test
Import output data in file mode into a database
-
When
eth-statediff-service
is run in file mode (database.type
) the output is in form of a SQL file or multiple CSV files. -
Assuming the output files are located in host's
./output_dir
directory. -
Create a directory to store post-processed output:
mkdir -p output_dir/processed_output
SQL
-
De-duplicate data:
sort -u output_dir/statediff.sql -o output_dir/processed_output/deduped-statediff.sql
-
Copy over the post-processed output files to the DB server (say in
/output_dir
). -
Run the following to import data:
psql -U <DATABASE_USER> -h <DATABASE_HOSTNAME> -p <DATABASE_PORT> <DATABASE_NAME> --set ON_ERROR_STOP=on -f /output_dir/processed_output/deduped-statediff.sql
CSV
-
De-duplicate data and copy to post-processed output directory:
# public.blocks sort -u output_dir/public.blocks.csv -o output_dir/processed_output/deduped-public.blocks.csv # eth.header_cids sort -u output_dir/eth.header_cids.csv -o output_dir/processed_output/deduped-eth.header_cids.csv # eth.uncle_cids sort -u output_dir/eth.uncle_cids.csv -o output_dir/processed_output/deduped-eth.uncle_cids.csv # eth.transaction_cids sort -u output_dir/eth.transaction_cids.csv -o output_dir/processed_output/deduped-eth.transaction_cids.csv # eth.access_list_elements sort -u output_dir/eth.access_list_elements.csv -o output_dir/processed_output/deduped-eth.access_list_elements.csv # eth.receipt_cids sort -u output_dir/eth.receipt_cids.csv -o output_dir/processed_output/deduped-eth.receipt_cids.csv # eth.log_cids sort -u output_dir/eth.log_cids.csv -o output_dir/processed_output/deduped-eth.log_cids.csv # eth.state_cids sort -u output_dir/eth.state_cids.csv -o output_dir/processed_output/deduped-eth.state_cids.csv # eth.storage_cids sort -u output_dir/eth.storage_cids.csv -o output_dir/processed_output/deduped-eth.storage_cids.csv # eth.state_accounts sort -u output_dir/eth.state_accounts.csv -o output_dir/processed_output/deduped-eth.state_accounts.csv # public.nodes cp output_dir/public.nodes.csv output_dir/processed_output/public.nodes.csv
-
Copy over the post-processed output files to the DB server (say in
/output_dir
). -
Start
psql
to run the import commands:psql -U <DATABASE_USER> -h <DATABASE_HOSTNAME> -p <DATABASE_PORT> <DATABASE_NAME>
-
Run the following to import data:
# public.nodes COPY public.nodes FROM '/output_dir/processed_output/public.nodes.csv' CSV; # public.nodes COPY public.blocks FROM '/output_dir/processed_output/deduped-public.blocks.csv' CSV; # eth.header_cids COPY eth.header_cids FROM '/output_dir/processed_output/deduped-eth.header_cids.csv' CSV; # eth.uncle_cids COPY eth.uncle_cids FROM '/output_dir/processed_output/deduped-eth.uncle_cids.csv' CSV; # eth.transaction_cids COPY eth.transaction_cids FROM '/output_dir/processed_output/deduped-eth.transaction_cids.csv' CSV FORCE NOT NULL dst; # eth.access_list_elements COPY eth.access_list_elements FROM '/output_dir/processed_output/deduped-eth.access_list_elements.csv' CSV; # eth.receipt_cids COPY eth.receipt_cids FROM '/output_dir/processed_output/deduped-eth.receipt_cids.csv' CSV FORCE NOT NULL post_state, contract, contract_hash; # eth.log_cids COPY eth.log_cids FROM '/output_dir/processed_output/deduped-eth.log_cids.csv' CSV FORCE NOT NULL topic0, topic1, topic2, topic3; # eth.state_cids COPY eth.state_cids FROM '/output_dir/processed_output/deduped-eth.state_cids.csv' CSV FORCE NOT NULL state_leaf_key; # eth.storage_cids COPY eth.storage_cids FROM '/output_dir/processed_output/deduped-eth.storage_cids.csv' CSV FORCE NOT NULL storage_leaf_key; # eth.state_accounts COPY eth.state_accounts FROM '/output_dir/processed_output/deduped-eth.state_accounts.csv' CSV;

NOTE:
COPY
command on CSVs inserts empty strings asNULL
in the DB. PassingFORCE_NOT_NULL <COLUMN_NAME>
forces it to insert empty strings instead. This is required to maintain compatibility of the imported statediff data with the data generated inpostgres
mode. Reference: https://www.postgresql.org/docs/14/sql-copy.html
