You asked: How many ordering services does the first default network created consist of in Hyperledger?

What is ordering service in Hyperledger Fabric?

Hyperledger Fabric works differently. It features a node called an orderer (it’s also known as an “ordering node”) that does this transaction ordering, which along with other orderer nodes forms an ordering service.

How many nodes does Hyperledger have?

There are three types of nodes: Client or submitting-client: a client that submits an actual transaction-invocation to the endorsers, and broadcasts transaction-proposals to the ordering service. Peer: a node that commits transactions and maintains the state and a copy of the ledger (see Sec, 1.2).

What is the default database used in Hyperledger Fabric?

LevelDB is the default key-value state database embedded in the peer process. CouchDB is an alternative external state database.

How many ordering services does the first default network created?

The build your first network (BYFN) scenario provisions a sample Hyperledger Fabric network consisting of two organizations, each maintaining two peer nodes. It also will deploy a “Solo” ordering service by default, though other ordering service implementations are available.
