Manually downloading era1 files
Files can be downloaded individually or in bulk using various methods:
# Download a specific era file for mainnet (e.g., block 0-8191)
curl -O https://data.ethpandaops.io/era1/mainnet/mainnet-00000-5ec1ffb8.era1
# Download checksums file
curl -O https://data.ethpandaops.io/era1/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/era1/mainnet/urls.txt | aria2c -i - --continue=true
# For sepolia, use:
curl -s https://data.ethpandaops.io/era1/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-era1 -v $(pwd):/downloads -w /downloads alpine \
sh -c "apk add --no-cache aria2 curl && \
curl -s https://data.ethpandaops.io/era1/mainnet/urls.txt | aria2c -i - --continue=true"
Verifying File Integrity
Verify downloaded era1 files using the pre-formatted checksums file:
# Download the formatted checksums file
curl -O https://data.ethpandaops.io/era1/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/era1/sepolia/checksums_sha256.txt
sha256sum -c checksums_sha256.txt --ignore-missing
