blvm-datum

DATUM Gateway mining protocol module for blvm-node.

Overview

Pool communication for the DATUM Gateway protocol (Ocean). Miners connect through blvm-stratum-v2; this module talks to the DATUM pool only.

• DATUM protocol client — encrypted pool channel when pool_public_key is configured
• Local templates — block templates via NodeAPI (get_block_template)
• Coinbase coordination — payout outputs from the pool at runtime (fetch_coinbaser / inter-module API)

Configuration

Pin both modules in node blvm.toml:

[modules]
blvm-stratum-v2 = "0.1.*"
blvm-datum = "0.1.*"

[modules.blvm-stratum-v2]
listen_addr = "0.0.0.0:3333"

[modules.blvm-datum]
pool_url = "https://ocean.xyz/datum"
pool_username = "user"
pool_password = "pass"
# pool_public_key = "hex_encoded_32_byte_public_key"  # optional
# reconnect_interval = 30
# min_difficulty = 1

Module data-dir config.toml uses the same keys (no [mining] table, no coinbase_tag_* or pool_address — those come from the pool).

Operator docs: Datum module in the BLVM book.
