Curso 1. The what, why and how of TEE Coprocessors
Módulo 1. Introduction to Offchain Computing

What is the definition of "offchain computing"?
B) Computation performed offchain, with results verified on-chain.

"Centralization concerns" and "Challenge periods" are "Cons" for which technology?
C) Layer 2 scaling (rollups)

Módulo 2. What are Coprocessors?

Which of the following is listed as a component of a coprocessor's general architecture?
A) Relay contracts

How do we distinguish coprocessors from rollups?
D) Rollups are described as sandboxed and "blockchain-esque," while coprocessors are compared to flexible VMs with attestations.

Módulo 3. Types of Coprocessors: TEEs, ZK, MPC, FHE

What "missing piece" in data protection does Confidential Computing address that Traditional Encryption leaves "Vulnerable"?
C) Data "In Use"

What is the only primary "con" or disadvantage listed for TEE (Trusted Execution Environment) Coprocessors?
D) Hardware vendor trust dependency

Módulo 4. Introduction to Trusted Execution Environments (TEEs)

What is the primary goal of remote attestations?
C) To verify that an attestation is valid, recent, and from a real enclave running a specific image.

Which TEE type is characterized by having "no persistent storage, external networking, or interactive access"?
C) AWS Nitro Enclaves

Módulo 5. Demonstration of an AI-based job matching app on BNB Chain

According to the project overview, what is the primary reason for using Marlin's Oyster TEE coprocessors?
B) To host verifiable Al (Llama 3.2) because blockchains cannot run Al and traditional APIs cannot be trusted.

What components are used to verify the TEE deployed Al's response onchain, as shown in the "Enclave Verification Data"?
B) The "Oyster Signature" and the "Enclave Public Key".

Curso 2. Building production-ready backends using TEEs

Módulo 1. Virtual Machine (VMs) vs Serverless Computing

According to the document, which computing model is characterized as "ephemeral," "stateless," and "event-driven"?
C) Serverless Computing

Which of the following is listed as a "con" of using Confidential Virtual Machines (CVMs)?
B) Upfront lease cost and longer cold start

Módulo 2. Networking and TLS connections

What is the primary networking challenge associated with AWS Nitro Enclaves, and how does Oyster solve it?
B) They only support vsock networking, so Oyster provides a simple IP interface to hide this complexity.

Which of the following is included in the checklist for verifying a decoded attestation document?
A) Verify that the certificate chain's root is the AWS Nitro Enclaves Root certificate.

Módulo 3. Key Management Systems (KMS)

According to the document, what is the fundamental purpose of a Key Management System (KMS)?
C) The lifecycle management of cryptographic keys, including their generation, storage, distribution, and rotation.

What is the core architectural difference between the Nautilus "Root Server" and "Derive Server"?
C) The Root Server derives public keys (publicly), while the Derive Server derives private keys (inside the enclave).

Módulo 4. Persistent Storage

Which of the following is listed as a key property of persistent storage in a TEE?
C) Data persists across the enclave lifecycle and is cryptographically protected.

Which of the following is not a characteristic of "Contract-Based Persistent Storage"?
D) It is a simple but rigid approach where the same code results in the same persistent keys.

Módulo 5. Reproducible Builds

What is the "Key Concept" of reproducible builds as defined in the document?
C) Same source code + Same build environment = Identical binary output.

According to the document, what is the "gap" that Remote Attestation alone cannot solve, which reproducible builds address?
A) Remote attestation verifies the binary (EIF) is running, but it doesn't prove what source code was used to create that binary.

Curso 3. Applications

Módulo 1. NodeJS server

What is the purpose of using npx pkg -t node18-alpine app.js in Step 2?
C) To create a self-contained binary that runs without installing nodejs inside the enclave.

In Step 5, how is the deployed NodeJS server interacted with, and what is the expected response?
B) By running curl <ip>:4000, expecting "Hello from Oyster Enclavel".

Módulo 2. Decentralized Frontends

What is the primary security benefit of this decentralized frontend approach?
B) It ensures that only enclaves running authorized images can request certificates for the domain, preventing tampering.

After fetching the subdomain, we have a waiting period of 4-5 minutes. What is happening during this time?
B) The enclave is updating the DNS records.

Módulo 3. AI Agents

In Step 3, what is the purpose of the --init-params ".env:1:1:file:./.env" flag in the oyster-cvm deploy command?
B) To pass the environment variables file into the enclave during deployment.

How does a user interact with the deployed Al agent, according to Step 4?
B) By running nc <Enclave_IP> 8080 and entering a prompt.

Módulo 4. ZK Proofs

According to the "About the App" section, what is the primary role of the Marlin Oyster CVM enclave in this ZK-proof application?
B) To secure the user's private inputs (age, BMI) so they cannot be leaked.

After deploying the server to a Marlin Oyster CVM, what command is used to perform a remote attestation to verify the enclave itself?
C) oyster-cvm verify -enclave-ip <ip>

Módulo 5. Serverless Subscriptions

Where does the user go to deploy the minified JavaScript function for the Marlin Oyster Serverless service?
B) They navigate to https://hub.marlin.org/oyster/serverless-sandbox/.

How is the deployed Marlin Oyster serverless function linked to the EthRate.sol smart contract before deployment?
C) The "transaction hash" (codeHash) from the serverless deployment is added to the script/deploy/EthRate.ts file.
