＋ VERIFIABLE & CONFIDENTIAL COMPUTE

# Different computations.  
Different responsibilities.

STAKR.space lists ZK proving, ciphernode and encrypted-compute activities. The directory keeps each protocol’s role and environment explicit.

## Proof generation: Fermah and Marlin Kalypso.

The Fermah entry links the cp0x prover profile. The Marlin Kalypso entry links a ZK-GPU generator profile. These are proving roles: the relevant evidence is a prover or generator record, not a proof-of-stake delegation address. Capacity, supported jobs and current availability must be checked with the respective service.

## Confidential coordination: Interfold.

Interfold uses Encrypted Execution Environments and committees of ciphernodes to coordinate computation over private inputs. STAKR.space links the network-wide dashboard. That dashboard is useful for exploration, but does not identify an individual STAKR ciphernode without a specific operator record.

## Encrypted compute: Octra devnet.

Octra describes its platform as encrypted compute for blockchain, AI and applications. The STAKR.space address currently points to its devnet explorer. Preserve that environment distinction: a devnet address is not a production service or a mainnet staking offer.

## Sequencing: Aztec.

Aztec is listed with a Genesis Sequencer provider link. A sequencer role should not be conflated with a generic proving service. Use the provider page to inspect current conditions.

Network-specific paid RPC access remains a separate product and is not connected on this site.
