What is blockchain?5:13
Explore blockchain as a distributed digital ledger that records transactions in linked, immutable blocks. The architecture enables secure, transparent, tamper-proof data across multiple parties and supports cryptography.
Mining blocks in blockchain network3:40
Nodes in a blockchain network mine blocks by solving a complex problem, earning tokens or fees, while broadcasting and verifying blocks to maintain a distributed ledger with cryptographic hashing.
Node Operators2:21
Learn node operations where every computer on the network holds a copy of the blockchain. See how a cryptographic hash links blocks to form a chain and keep nodes synchronized.
Consensus mechanisms (POW vsPOS)2:32
Explore consensus mechanisms, compare proof of work and proof of stake, and see how mining and staking secure a decentralized ledger.

What is ethereum?1:48
Ethereum enables developers to deploy decentralized applications and programmable smart contracts on an open source blockchain, using ether for transactions and executing terms automatically without intermediaries.
What is gas in ethereum?1:35
learn how gas in Ethereum determines the cost of transactions and smart contracts through the internal pricing mechanism, the gas limit, and alternatives on low-fee evm networks.
Other networks to deploy ethereum contracts1:25
Deploy Ethereum smart contracts on networks like Binance Smart Chain, Polygon Matic, Fantom, and Optimism to reduce gas fees and speed up transactions using layer two scaling and optimistic rollups.

SPDX licence and solidity version6:55
Learn how to specify the SPDX license identifier and the solidity version with a version pragma in .sol files using Remix IDE, enabling smooth compilation and deployment.
Write your first smart contract4:27
Write your first smart contract in solidity, with contract Hello World, a public string greet initialized to Hello World, and observe comments, data types, and visibility in remix.
Environment, account and gas limit4:55
Explore Remix environment, accounts, and gas limit for deploying contracts. Learn that environment is the Remix virtual machine, accounts hold test ether, and gas limit caps contract costs.
Deploy the smart contract in remix IDE8:30
Deploy your smart contract in Remix IDE after compiling and selecting an account, then review gas, status, and the contract address, and read the public Hello World value via UI.

Counter contract10:55
Learn to build a counter smart contract in Remix, using a public unsigned integer count and functions to get, increment, and decrement the value.
Visibility types1:34
Learn about Solidity state variable visibility types, including public getters, private and internal access, and why external is not valid for state variables but used for functions.
Function modifiers in solidity4:50
Explore solidity function modifiers to control visibility and behavior, including view, pure, payable, external, internal, public, and private, covering read only data access and state independent calculations.
Solidity variables7:33
Explore Solidity primitive data types boolean, uint, int, and address, and distinguish local, state, and global variables like block.timestamp and msg.sender while noting gas costs for deployment and updates.
Local state and global variables10:43
Explore declaring state and local variables in a Solidity smart contract, access global variables like the block timestamp and current address via sender, and use memory data location for returns.
Getting help from google and chatgpt4:06
Learn how to debug Solidity smart contracts efficiently using Google and ChatGPT, understand memory in Solidity, and quickly resolve errors with AI-assisted tooling.
Where to go from here?0:18
