This map lists the core blockchain topics, the point where students most often get stuck, and how a tutor helps you past it.
| Topic | Where students get stuck | How a tutor helps |
|---|---|---|
| Hashing | Hash functions and block linking | Worked hashing examples |
| Merkle trees | Efficient transaction proofs | Worked proof-size examples |
| Signatures | Public keys and transaction signing | Signing flow diagrams |
| Consensus | Proof of work and proof of stake | Mechanism comparisons |
| Mining difficulty | Expected hashing effort | Worked difficulty calculations |
| Smart contracts | Solidity basics and testing | Code reviews |
| Gas | Transaction fees on Ethereum | Worked gas calculations |
| Security and use cases | Common vulnerabilities and applications | Case studies |
Tutors cover concepts and development.
| Area | Topics |
|---|---|
| Foundations | Distributed ledgers, hashing, blocks, immutability |
| Cryptography | Public-key cryptography, digital signatures, Merkle trees |
| Consensus | Proof of work, proof of stake, Byzantine fault tolerance |
| Platforms | Bitcoin, Ethereum, permissioned blockchains such as Hyperledger Fabric |
| Smart contracts | Solidity, testing, deployment, gas optimisation |
| Security | Reentrancy, integer overflow, access control flaws |
| Applications | Supply chains, digital identity, payments, tokenisation |
Two core calculations.
| Question | Working | Answer |
|---|---|---|
| A block has 8 transactions. Hashes needed to prove one transaction is included | log₂ 8 | 3 sibling hashes |
| A block needs a hash with 20 leading zero bits. Expected hash attempts | 2²⁰ | ≈ 1,048,576 |
| Expected time at 1 million hashes per second | 1,048,576 ÷ 1,000,000 | ≈ 1.05 seconds |
Real networks adjust difficulty so blocks arrive at a target interval, about 10 minutes for Bitcoin.
A smart contract call uses 50,000 gas at a gas price of 20 gwei (1 gwei = 10⁻⁹ ETH). Illustrative figures only.
| Step | Working | Result |
|---|---|---|
| Fee in gwei | 50,000 × 20 | 1,000,000 gwei |
| Fee in ETH | 1,000,000 × 10⁻⁹ | 0.001 ETH |
| Code that changes state | `function setValue(uint v) public { value = v; }` | Costs gas when called in a transaction |
| Read-only code | `function getValue() public view returns (uint) { return value; }` | Free when called off-chain |
Writing to storage is one of the most expensive operations, so efficient contracts minimise storage writes.
Tutors match your level, syllabus and exam board, from school to PhD.
| Level | What you study | Matching help |
|---|---|---|
| Beginners | Programming and blockchain concepts | Programming Fundamentals and live tutoring |
| Undergraduate computing | Blockchain modules and projects | Data Structures, Discrete Structures |
| Final-year and master's projects | dApps and smart contract systems | Software Engineering and assignment help |
| Fintech and business courses | Blockchain applications and regulation | Homework help |

Most lost marks come from unclear explanations and insecure contracts.
| Mark-loser | What to do instead |
|---|---|
| Saying blockchains cannot be changed at all | Explain immutability in terms of cost and consensus |
| Confusing proof of work and proof of stake | Compare how each selects block producers |
| Contracts without tests | Write unit tests for each function |
| Reentrancy vulnerabilities | Update state before external calls |
| Blockchain used where a database would do | Justify why decentralisation is needed |
| Treating coursework as investment advice | Focus on technology and design |
Blockchain is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Smart contract projects | Working, tested contracts with documentation |
| Reports | Clear explanations of design and security |
| Case studies | Evaluating blockchain for a real problem |
| Exams | Concepts, cryptography basics and consensus |
| Presentations | Demonstrating dApps |
Blockchain developers use these tools.
| Tool | What it is used for |
|---|---|
| Remix IDE | Writing and testing Solidity |
| Hardhat or Foundry | Development and testing frameworks |
| Test networks | Deploying without real funds |
| MetaMask | Interacting with dApps |
| Block explorers | Inspecting transactions |
Blockchain is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where blockchain is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | Computer science and fintech degrees | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | Blockchain and distributed systems courses | Letter grades A–F and a 4.0 GPA scale | IEEE or ACM |
| Australia | IT and fintech degrees | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Computer science programmes | Letter grades or percentages; GPA scales vary by province and university | IEEE or ACM |
| India | B.Tech/BE CSE electives, MCA and blockchain certificate courses | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of blockchain help depends on the project size and your deadline. A single contract fix costs less than a full dApp project. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Student reviews
Used FLN Tutors? Be one of the first to share how it went, in writing or in a short video.
Yes. Tutors help design, code and explain blockchain projects, within your course's rules.
A distributed ledger made of linked blocks of transactions, secured by cryptography and consensus.
Each block stores the hash of the previous block, so changing one block changes every later hash.
A tree of hashes that summarises all transactions in a block and allows efficient inclusion proofs.
A consensus method where miners compete to find a hash below a target, which costs computing effort.
A consensus method where validators are chosen based on the stake they lock up.
A program stored on a blockchain that runs automatically when called.
A unit measuring computational work; fees equal gas used × gas price.
When a contract is called back before it updates its state, letting an attacker withdraw repeatedly.
Anyone can join a public blockchain; permissioned blockchains restrict who can participate.
When one party controls most of the network's mining or staking power and can rewrite recent history.
A decentralised application that uses smart contracts for its back-end logic.
Payments, supply chain tracking, digital identity and asset tokenisation, among others.
Yes. Tutors help you write, test and secure Solidity contracts.
The concepts take time; building small contracts helps.
Tutors work from your course text, such as Narayanan et al.'s Bitcoin and Cryptocurrency Technologies.
Often, yes, for short code problems, depending on tutor availability.
No. Tutoring is educational only and does not include investment advice.
Yes. Tutoring, worked examples and feedback are a normal part of learning. You should use the explanations to understand the method and submit your own work in line with your school's or university's academic integrity rules. See our academic integrity policy.
Yes. Your files and details are used only to help you and are not shared with your school or university. See our privacy policy.
