Section 1 — Understanding the Internet and Web3
A review of the early internet, Web2, and Web3 with knowledge questions, vocabulary matching, and a scenario comparing centralized and decentralized recordkeeping.
Estimated time: 60–90 minutes
Educational boundary: This review provides general education about technology and preparation. It does not provide individualized financial, investment, legal, or tax advice. It does not recommend any network, company, product, or digital asset. You do not need internet access, an account, a wallet, or a digital asset to complete this review.
You have completed the first four lessons of Understanding Web3. This review gives you a place to pause, strengthen your vocabulary, and apply the ideas before moving into blockchain foundations.
I encourage you to treat the review as part of the learning process rather than as a test of whether you remembered every sentence. Attempt each question first. When you find a gap, return to the lesson, study the relevant passage, and revise your response. That cycle can help you develop the habits of a self-directed learner.

Four community organizations help people find lawful employment training, transportation, food assistance, and educational programs. The organizations want one digital record that lists available services, eligibility requirements, contact information, and the date each listing was last verified. The record will not contain participants' private information.
The organizations are comparing two designs.
Design A — One organization maintains the record: One nonprofit operates the official database. Staff members from the other organizations send updates to that nonprofit. The nonprofit checks the information, publishes changes, corrects errors, and answers questions. This design creates one accountable contact and may allow fast, consistent decisions. The other organizations must depend on the nonprofit's security, staffing, policies, and continued operation.
Design B — The organizations maintain a shared record: Each of the four organizations keeps a synchronized copy. Shared technical rules explain how an approved organization proposes an update. At least two organizations must verify an important change before it becomes part of the record. A governance agreement explains how the group resolves disagreements and replaces an organization that stops participating. This design divides control and reduces reliance on one recordkeeper. It also requires coordination, compatible systems, clear responsibilities, and a process for correcting inaccurate information.
Before moving to Section 2, ask yourself whether you can:
If one statement remains difficult, return to the relevant lesson and write a brief explanation in your own words. That review is evidence that you are monitoring your understanding and directing your learning.
You may submit your completed review as a dated Profile journal entry, subject to your facility's rules. Include your name or approved Profile identifier, Understanding Web3 — Section 1 Review, and the date you completed the work.
Use one of the established Prison Professors Profile methods:
Keep a copy when circumstances permit. Never include passwords, private keys, seed phrases, authentication codes, account numbers, or other sensitive credentials.
