Access content on the Portal network

Once you have a Fluffy node connected to network with the JSON-RPC interface enabled, then you can access the content available on the Portal network.

You can for example access execution layer blocks through the standardized JSON-RPC call eth_getBlockByHash:

# Get the hash of a block from your favorite block explorer, e.g.:
BLOCKHASH=0x34eea44911b19f9aa8c72f69bdcbda3ed933b11a940511b6f3f58a87427231fb # Replace this to the block hash of your choice
# Run this command to get this block:
curl -s -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":"1","method":"eth_getBlockByHash","params":["'${BLOCKHASH}'", true]}' http://localhost:8545 | jq

Note

The Portal testnet is slowly being filled up with historical data through bridge nodes. Because of this, more recent history data is more likely to be available.

You can also use our blockwalk tool to walk down the blocks one by one:

make blockwalk

BLOCKHASH=0x34eea44911b19f9aa8c72f69bdcbda3ed933b11a940511b6f3f58a87427231fb # Replace this to the block hash of your choice
./build/blockwalk --block-hash:${BLOCKHASH}
