Word	Definition
Consensus Server	The MobileCoin Consensus Service facilitates transactions between MobileCoin users. The MobileCoin Consensus Protocol solves the Byzantine Agreement Problem by requiring each user to specify a set of peers that they trust, called a quorum.
Consensus Validator Node	Runs Intel’s Software Guard eXtensions (SGX), which provides defense-in-depth improvements to privacy and trust.
IAS Account	An account after you have obtained your Intel Attestation Service credentials.
MobileCoin LedgerDB	Storage location for the LedgerDB containing downloaded blocks.
MobileCoin Tokens (MOB)	MobileCoin tokens (MOB, pronounced mohb) are a new cryptocurrency that you can send over the internet.
Mobilecoind	A payment system that lets you send money over the internet using a new currency called “mobilecoins” or MOB.
mobilecoindDB	Storage location for the mobilecoindDB containing indexed transactions for registered accounts.
MRENCLAV	The measurement of the enclave. A stronger measurement of the key that includes all of the contents of the enclave, as well as MRSIGNER.
MRSIGNER	A measurement of the key, which was used to sign the enclave, but does not contain any contents of the enclave itself.
Quorum Set: Trusted and Untrusted Peers	To run consensus, you must develop a quorum set that provides the basis of trust required to solve the Byzantine Agreement Problem. You must also link your identity to your node for both Intel's attestation verification, as well as to sign messages in consensus. Determine who you trust for your quorum. By figuring out who to include in your quorum set, you specify peers that you trust. MobileCoin uses Universal Resource Identifiers (URIs) to specify peers. These include the address of the peer, the peer's public key, and can optionally include connection information, such as the certificate authority bundle, and tls-hostname.
Secure Enclaves	The MobileCoin Network implements secure enclaves using Intel’s Software Guard eXtensions (SGX) to process new transactions according to the MobileCoin Consensus Protocol for integrity and confidentiality. Recent advances in trusted computing make it possible to run software on a remote host without exposing sensitive data to that server’s operator, even when she has complete control of the remote computer’s operating system (i.e. root access).
Universal Resource Identifiers (URIs)	Used by MobileCoin to specify peers. The information includes the address of the peer, the peer's public key, and can optionally include connection information, such as the certificate authority bundle, an the tls-hostname.
