Study Notes

Blockchain Fundamentals: A Comprehensive Guide

Blockchain is a distributed ledger technology that enables secure and transparent transactions without the need for intermediaries.
A blockchain network consists of nodes that run the blockchain's software to validate and store the complete history of transactions.
Blockchains are suited for smart asset lifecycle management and financial use cases that require transparency and reduced need for intermediaries.
Distributed Ledger Technologies (DLTs) are similar to blockchains but can have different structures and are suited for multiple use cases.
Blockchains have four layers: Infrastructure, Logical, Application, and User Interface.
There are different types of blockchains, including Layer-0, Layer-1, Layer-2, permission-less, permissioned, federated, and EVM-compatible chains.
Blockchain consensus mechanisms are the heart of blockchains, and there are over 75 consensus algorithms, including Proof-of-Work (PoW), Proof-of-Stake (PoS), and Delegated Proof of Stake (DPoS).
Blockchain bridges allow the transfer of assets between different blockchains, and they can be trusted or trustless.
Blockchain forks occur when a single blockchain splits into two, and they can be hard or soft forks.
Blockchain addresses consist of a public key and a private key, and they are used to send and receive crypto assets.
Blockchain wallets are designed to store and manage crypto assets securely, and there are four main types: hot wallets, cold wallets, paper wallets, and hardware wallets.
Merged mining is the process of mining two or more blockchains at the same time, and it increases the profitability and performance of mining.Key Points on Blockchain and DLT
Metamask wallets provided by crypto exchanges are custodial, meaning the private keys are under the control of the exchange, putting your crypto at risk if they go bankrupt.
Blockchain networks use record-keeping models to determine the provenance and ownership of coins, with three types of models: Bitcoin transaction model, UTXO model, and account/balance model.
Blockchains and DLTs are often used interchangeably, but there are important differences: a blockchain has a linear chronological structure, while DLTs can have different structures, and DLTs are suited for multiple use cases.
Blockchain is suited for smart asset lifecycle management, increases transparency, and reduces the need for intermediaries in financial use cases.
Blockchain developers build a variety of projects such as crypto wallets, payment systems, tokens, marketplaces, DeFi projects, oracles, scaling solutions, and metaverse assets.
The Government of India's National Strategy on Blockchain lists 44 use cases for blockchain technology.
Mindmaps can be a useful tool to understand and visualize the complex concepts of blockchain and DLTs.
Not your keys, not your coins is a common phrase in the cryptocurrency world, reminding users to keep their private keys secure.
UTXO model can be compared to spending banknotes and getting back change, while the account/balance model can be compared to spending using a debit or credit card.
DLTs can have different structures, such as directed acyclic graphs (DAGs) or hashgraph, which are not linear like blockchains.
Blockchain and DLTs have potential use cases beyond finance, such as supply chain management, voting systems, and identity verification.
Blockchain's decentralized nature makes it resistant to censorship and manipulation, making it a potential tool for promoting democracy and transparency.
