Full History Archives (eraE)
The eraE files contain the complete Ethereum execution layer history from genesis, covering both pre-merge (PoW) and post-merge (PoS) blocks. This is the recommended format for full chain import, enabling historical inspection, client bootstrapping, and independent verification. Each file is cryptographically verifiable using included SHA256 checksums.

Manually downloading eraE files
Files can be downloaded individually or in bulk using various methods:
# Download a specific eraE file for mainnet
curl -O https://data.ethpandaops.io/erae/mainnet/mainnet-00000-xxxxxxxx.erae
# Download checksums file
curl -O https://data.ethpandaops.io/erae/mainnet/checksums.txt
# Download all files using aria2c (recommended for bulk downloads)
# This uses parallel connections for faster downloads
curl -s https://data.ethpandaops.io/erae/mainnet/urls.txt | aria2c -i - --continue=true
# For sepolia, use:
curl -s https://data.ethpandaops.io/erae/sepolia/urls.txt | aria2c -i - --continue=true
# Using Docker (if aria2c is not installed locally)
# This mounts the current directory to save downloads
docker run --rm -it --name download-erae -v $(pwd):/downloads -w /downloads alpine \
sh -c "apk add --no-cache aria2 curl && \
curl -s https://data.ethpandaops.io/erae/mainnet/urls.txt | aria2c -i - --continue=true"
Verifying File Integrity
Verify downloaded eraE files using the pre-formatted checksums file:
# Download the formatted checksums file
curl -O https://data.ethpandaops.io/erae/mainnet/checksums_sha256.txt
# Verify all downloaded files (ignores missing files)
sha256sum -c checksums_sha256.txt --ignore-missing
# For sepolia:
curl -O https://data.ethpandaops.io/erae/sepolia/checksums_sha256.txt
sha256sum -c checksums_sha256.txt --ignore-missing

Pre-merge Archives (era1)
The era1 files contain historical data for the former Ethereum proof-of-work chain. For mainnet it's starting at genesis on July 30, 2015 and ending at the merge block 15537393 on September 15, 2022 is available from the following sources, enabling historical inspection, client bootstrapping, and independent verification. Each file is cryptographically verifiable using included SHA256 checksums.
