What this session would cover
Proposed outline — the mentor finalises the agenda once this topic is scheduled.
- 1Why blockchain & decentralized systems matters — the common problem: Smart contracts get deployed untested, and bugs become permanent losses.
- 2Core concepts in plain language: Distributed ledgers, cryptographic hashes, consensus mechanisms, smart contracts, wallets, transaction execution
- 3Going further: decentralized applications, oracles, layer-two systems, contract testing, protocol security
- 4Framework walkthrough: Amdahl's Law, Threat Models for Decentralized Systems, Privacy Budgets (ε)
- 5Practical workflow, built live: A smart contract with unit tests, a security checklist and a when-not-to-use-blockchain note.
- 6How to measure it: Speed-up versus baseline, Numerical error, Security review findings
- 7An illustrative case (a fictional example, not a client result), then live Q&A on your own situation
Who it's for
- • Students and freshers entering tech
- • Working developers and engineers
- • Tech leads and architects
You'd leave with
- A smart contract with unit tests, a security checklist and a when-not-to-use-blockchain note.
- A working understanding of Amdahl's Law and Threat Models for Decentralized Systems
- A short list of measures to track: Speed-up versus baseline, Numerical error, Security review findings
