Blockchain Technology Training in Vizag | Softenant Technologies
Blockchain is a distributed ledger technology built from blocks, hashes, signatures, consensus rules and network participants. This course covers Ethereum-style accounts, wallets, smart-contract concepts, Solidity fundamentals, Web3 interaction and dApp architecture.
Technology-specific learning focus
Learners examine the trade-offs behind decentralised systems: key custody, transaction fees, contract immutability, permissions, scalability and when a conventional database is the better choice.
Skills and syllabus areas
- Blocks, hashes, nodes and consensus
- Wallets, keys, signatures and transactions
- Ethereum accounts and smart-contract concepts
- Solidity functions, state and testing concepts
- Web3, dApp flow and security hygiene
Project evidence
How practical work is assessed
Projects are reviewed against defined inputs, implementation choices, test cases, output quality and documented limitations. Learners should be able to explain the workflow, not just show a final screen or code sample.
Blockchain Technology course syllabus: 20 modules
This 20-module syllabus is structured around the tools, decisions and practical outputs used in Blockchain Technology work. Each module is tied to a demonstrable task, not a generic learning-stage label.
Blockchain use cases, limitations and distributed-ledger concepts
Use a decision matrix to compare blockchain with a conventional database for three scenarios, then produce a justified technology recommendation.
Blocks, transactions, hashes and tamper-evidence
Hash sample transactions with a browser or Python hashing tool and link them into blocks, then produce a tamper-evidence demonstration.
Nodes, peer-to-peer networks and ledger replication
Model nodes and ledger replication in diagrams.net and simulate an update across peers, then produce an annotated network diagram.
Public and private keys, signatures and wallet security
Generate practice keys and sign a test message with an approved wallet tool, then produce a key-custody and verification checklist without exposing secrets.
Consensus approaches and validator/miner role concepts
Compare proof-of-work and proof-of-stake flows in a worksheet, calculate trade-offs, then produce a validator-role comparison.
Ethereum accounts, gas and transaction lifecycle
Inspect a testnet transaction in MetaMask and a block explorer, trace gas and confirmations, then produce a transaction-lifecycle record.
Smart-contract design, state and function concepts
Design contract state, functions and access rules before coding in Remix IDE, then produce a reviewed smart-contract specification.
Solidity syntax, data types and control flow
Write Solidity variables, data types and control flow in Remix IDE, compile the contract, then produce warning-free source code.
Solidity functions, visibility and events
Implement Solidity functions, visibility rules and events in Remix IDE, then produce a deployed test contract with event logs.
Contract testing, debugging and common security risks
Use Remix tests and debugger tools to reproduce common contract risks, correct them, then produce passing tests and a security note.
Web3 application architecture and provider concepts
Map the wallet, Web3 provider, frontend and smart contract in diagrams.net, then produce an end-to-end dApp architecture.
Wallet-to-dApp connection and transaction signing flow
Connect a test wallet to a practice dApp and sign a testnet transaction, then produce a documented connection and confirmation flow.
Tokens, standards and token-economy concepts
Implement a basic token contract from a standard template in Remix IDE, then produce test balances and transfer evidence.
Decentralised identity and certificate-verification ideas
Design a decentralised certificate record with issuer, holder and verification fields, then produce a privacy-aware data model.
Supply-chain traceability and provenance workflow
Map product events to blockchain transactions for a supply-chain scenario, then produce a provenance workflow and sample ledger entries.
Scalability, fees and layer-two concepts
Compare base-layer and layer-two fees with block-explorer data, then produce a scalability and cost worksheet.
Privacy, permissions and regulatory considerations
Review a dApp data flow for personal data, permissions and legal risk, then produce a privacy and controls checklist.
Certificate-verification ledger project
Build a certificate-verification contract in Remix IDE and test issue and verify actions, then produce deployed testnet evidence.
Solidity smart-contract project and test cases
Develop a Solidity contract with positive and negative test cases, then produce source code, passing tests and a defect log.
Web3 dApp architecture and project presentation
Connect a simple Web3 interface to the tested contract, then produce a working dApp demo plus an architecture and project presentation.
Practical Blockchain Technology workflow and project depth
Ledger architecture, hashing and consensus
A blockchain records transactions in linked blocks whose hashes make unauthorised changes visible. Nodes maintain copies of the ledger and use a consensus approach to agree on valid state changes. The course compares this model with a conventional database, including the trade-offs in speed, privacy, governance and operational cost. Learners should be able to identify when a distributed ledger provides real value and when it adds unnecessary complexity.
Wallets, keys and transaction lifecycle
A wallet manages credentials used to sign transactions; it does not remove the responsibility of safeguarding private keys. Learners follow the lifecycle from account selection and transaction creation through signing, network submission, validation and confirmation. Ethereum-style concepts such as gas, account balances and transaction fees are discussed so that a dApp project can explain user-facing costs and failure cases clearly.
Solidity, smart contracts and Web3
Smart contracts are programs whose state and functions run in a blockchain environment. The Solidity section covers data types, functions, visibility, events and testing concepts, alongside common risks such as incorrect access control or unsafe assumptions about external input. Web3 architecture connects a browser interface, wallet, provider and contract. This makes it clear that a decentralised application contains both on-chain logic and ordinary client-side engineering.
Blockchain project and responsible use
Projects include a certificate-verification ledger, supply-chain traceability model and a simple contract-driven dApp design. Each project documents what is stored on-chain, what stays off-chain, who can submit a transaction, how a wallet signs it and how the result is verified. Learners also discuss immutability, privacy, key management, transaction costs and regulatory considerations instead of presenting blockchain as suitable for every business problem.
Smart-contract security and project documentation
Smart-contract projects must document access controls, expected state changes, failure conditions and test cases. Learners distinguish a prototype from a production-ready system and explain why contract code may require independent review before real assets are involved. This security-first approach strengthens discussions of Solidity, wallets, Web3 and responsible decentralised application design.
Blockchain design decisions and limitations
A blockchain solution must justify its design. Learners document the participants, the transaction that changes state, the wallet or identity used to authorise that change, the information stored on-chain, the information stored off-chain and the cost or privacy limitation involved. This makes an Ethereum or Web3 project technically defensible rather than a generic decentralisation claim.
