Hedera networks are comprised of two types of nodes: Consensus and Mirror nodes. The Hedera mainnet
consensus nodes are currently permissioned; operated by the Hedera Governing Council. Consensus nodes receive transactions from clients, charge transaction fees, and contribute to consensus being achieved.
Mirror nodes are permissionless, and store the history of transactions for optimized queries. Mirror nodes do not submit transactions to the network from clients nor do they participate in consensus.
Are you see something different? It appears that the mainnet and consensus are one in the same.
The Hedera Mainnet is currently comprised of permissioned consensus nodes operated by the Hedera Governing Council
