Course outline and revision prompts
Module 1
Blockchain: Financial foundations
Apply Blockchain through value, risk, markets.
Lesson
Key terms
Revision question
Value with Blockchain
value, Blockchain, finance
In Blockchain & Web3 Development, which evidence best supports a value result produced with Blockchain?
Risk with Solidity
risk, Solidity, finance
In Blockchain & Web3 Development, which evidence best supports a risk result produced with Solidity?
Markets with DeFi
markets, DeFi, finance
In Blockchain & Web3 Development, which evidence best supports a markets result produced with DeFi?
Instructional figureProcess flow
Value: from context to evidence
Value connects records and assumptions to a reconciled decision in Blockchain & Web3 Development.
1Records and assumptions
Define the purpose, intended user and Blockchain constraints.
frames
2Value
Separate nominal and present value with stated assumptions.
produces evidence for
3Reconciled decision
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Value is credible only when the result can be traced back to its purpose, inputs and constraints. Value is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 2
Solidity: Tools and data
Apply Solidity through records, analysis, controls.
Lesson
Key terms
Revision question
Records with Smart Contracts
records, Smart Contracts, finance
In Blockchain & Web3 Development, which evidence best supports a records result produced with Smart Contracts?
Analysis with Web3
analysis, Web3, finance
In Blockchain & Web3 Development, which evidence best supports a analysis result produced with Web3?
Controls with Blockchain
controls, Blockchain, finance
In Blockchain & Web3 Development, which evidence best supports a controls result produced with Blockchain?

Records: from context to evidence
Records connects records and assumptions to a reconciled decision in Blockchain & Web3 Development.
1Records and assumptions
Define the purpose, intended user and Smart Contracts constraints.
frames
2Records
Reconcile the ledger to an independent source.
produces evidence for
3Reconciled decision
Compare the observed result with a normal case, boundary case and stated limitation.
Review the evidence, adjust the method, and repeat.
Takeaway: Records is credible only when the result can be traced back to its purpose, inputs and constraints. Records is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 3
DeFi: Applied decisions
Apply DeFi through scenarios, evaluation, reporting.
Lesson
Key terms
Revision question
Scenarios with Solidity
scenarios, Solidity, finance
In Blockchain & Web3 Development, which evidence best supports a scenarios result produced with Solidity?
Evaluation with DeFi
evaluation, DeFi, finance
In Blockchain & Web3 Development, which evidence best supports a evaluation result produced with DeFi?
Reporting with Smart Contracts
reporting, Smart Contracts, finance
In Blockchain & Web3 Development, which evidence best supports a reporting result produced with Smart Contracts?

Scenarios: from context to evidence
Scenarios connects records and assumptions to a reconciled decision in Blockchain & Web3 Development.
1Records and assumptions
Define the purpose, intended user and Solidity constraints.
frames
2Scenarios
Use base, downside and upside without invented probabilities.
produces evidence for
3Reconciled decision
Compare the observed result with a normal case, boundary case and stated limitation.
Takeaway: Scenarios is credible only when the result can be traced back to its purpose, inputs and constraints. Scenarios is the decision layer between the starting context and evidence that the result is fit for purpose.
Module 4
Smart Contracts: Risk and governance
Apply Smart Contracts through security, regulation, review.
Lesson
Key terms
Revision question
Security with Web3
security, Web3, finance
In Blockchain & Web3 Development, which evidence best supports a security result produced with Web3?
Regulation with Blockchain
regulation, Blockchain, finance
In Blockchain & Web3 Development, which evidence best supports a regulation result produced with Blockchain?
Review with Solidity
review, Solidity, finance
In Blockchain & Web3 Development, which evidence best supports a review result produced with Solidity?
Instructional figureContinuous cycle
Security: from context to evidence
Security connects records and assumptions to a reconciled decision in Blockchain & Web3 Development.
1Records and assumptions
Define the purpose, intended user and Web3 constraints.
frames
2Security
Use strong authentication and independent confirmation.
produces evidence for
3Reconciled decision
Compare the observed result with a normal case, boundary case and stated limitation.
Review the evidence, adjust the method, and repeat.
Takeaway: Security is credible only when the result can be traced back to its purpose, inputs and constraints. Security is the decision layer between the starting context and evidence that the result is fit for purpose.
Course practical outcome
Produce a reviewable Blockchain & Web3 Development project using Blockchain, Solidity, DeFi.
Expected output: A working Blockchain & Web3 Development artefact plus an evidence-based self-review.
Tools: A suitable Blockchain environment, A plain-text decision log, Test data or realistic sample material
Production steps
Define the intended user, outcome and constraints.
Create the smallest complete result using Blockchain.
Test one normal case, one boundary case and one failure response.
Revise the work from the evidence and preserve before-and-after results.
Prepare a concise handover containing method, limitations and next step.
Success criteria
The output matches the stated outcome.
Inputs and decisions are reproducible.
Boundary and failure evidence is included.
Limitations and responsibility considerations are explicit.
Self-review
Can another learner repeat the method?
Did I test a difficult case?
Did I avoid unsupported claims?
Is the next action proportionate to the remaining risk?
Safety note: This course is general education, not financial, investment, tax or legal advice.
Next step: Choose one weakness found during review and improve it before extending the Blockchain scope.
