Pull a block stream in one command

Set $SF_API_TOKEN to a key from your dashboard, then run this against Unichain Mainnet.

grpcurl -H "authorization: Bearer $SF_API_TOKEN" \

mainnet.unichain.streamingfast.io:443 \
sf.firehose.v2.Stream/Blocks

Streams the 100 most recent blocks from Unichain Mainnet. Firehose reads a negative start_block_num as an offset back from chain head, so no head lookup is needed.
