๐ Blockchain and smart contract engineering skills are in high demand, with an average salary of a solidity developer being between 150 and 175,000. This course is designed for engineers with some experience in Python programming and aims to teach them all the skills they need to become a smart contract expert.
โ๏ธ Blockchain and smart contracts bring decentralization, transparency, speed, security, immutability, and trustlessness to agreements and transactions. Smart contracts are self-executing pieces of code that can remove conflicts of interest in traditional agreements, enabling trustless and trust-minimized agreements.
๐ผ Blockchain and smart contract technology has led to the emergence of decentralized applications (DApps) and decentralized autonomous organizations (DAOs). These technologies offer economic opportunities, freedom from centralized control, and the ability to engage in trustless interactions.
๐ Securing the mnemonic phrase and private keys is crucial as they provide access to multiple accounts and losing them means losing access to all accounts.
๐ Metamask allows users to interact with different networks, including Ethereum mainnet and testnets, for testing applications without using real money.
๐ธ Transactions on the blockchain require gas, which is the fee paid to node operators, and the gas price determines the speed of transaction processing.
๐ Private keys are used to sign transactions and should be kept private.
๐ Public keys and addresses are derived from the private key and can be made public.
โ๏ธ Blockchain technology provides a decentralized and secure network of independent nodes.
๐ผ Consensus mechanisms, such as proof of work and proof of stake, ensure agreement on the state of the blockchain.
๐ Blockchain networks are resistant to sybil attacks and 51% attacks.
โก Scalability is addressed through solutions like sharding and layer 2 protocols.
