These slides explore mechanics Bitcoin Lightning Network as Layer 2 scaling solution in detail . We have also discussed 0x protocol used as recipe for decentralized exchanges and Matic network as scaling solution for ethereum.
The Lightning Network aims to solve Bitcoin's problems of slow payments, high transaction costs, and poor scalability. It allows for instant, very low-cost payments between nodes by conducting transactions off-blockchain through payment channels. There are currently three main implementations of Lightning that have achieved compatibility. The network functions as a layer on top of Bitcoin through defined BOLT protocols, forming a decentralized network of payment channels between nodes.
The document introduces the Lightning Network as a solution to Bitcoin's scalability problems. It explains that Lightning Network creates payment channels between parties that allow for fast, low-cost transactions without broadcasting to the blockchain. Transactions are enforced through smart contracts. This allows the network to potentially process millions of transactions per second through payment hubs and routes. It outlines several open source Lightning Network implementations that are being developed to support the network.
The document provides an overview of cryptography and cryptocurrency such as Bitcoin. It discusses how cryptography works through encryption and decryption with keys. Cryptocurrency uses cryptography for security and transactions are recorded on a public blockchain. Bitcoin was the first major cryptocurrency and works on a decentralized peer-to-peer network without a central authority. Users can make transactions with minimal fees and Bitcoin can be used to purchase goods and services from many companies.
The document discusses the Lightning Network, which aims to scale bitcoin transactions by enabling instant, low-cost payments through off-chain payment channels. It describes key concepts like payment channels, routing payments across multiple nodes, and implementations. The Lightning Network allows for near-instant micropayments, smart contracts, and cross-chain atomic swaps by using timelocks and hashed timelock contracts to securely transfer bitcoin off the main blockchain.
This document provides an overview of cryptocurrencies and Bitcoin. It defines cryptocurrency and describes how Bitcoin works as a decentralized digital currency using cryptography to regulate currency generation and verify fund transfers without a central bank. Key aspects covered include currency vs Bitcoin, Bitcoin expansion, cryptography basics like hashing and digital signatures, blockchain data structures, mining and proof-of-work consensus, and incentives to maintain the Bitcoin network.
The Lightning Network - A gentle introductionRoland Stadler
The Lightning Network allows for instant, low-cost payments on Bitcoin through the use of payment channels and a mesh network. It provides greatly improved scalability over Bitcoin by taking transactions off-chain, where local consensus between peers is sufficient instead of global consensus on the blockchain. While adding complexity, it enables new use cases like micropayments and improves privacy. Real-world examples demonstrate its viability for coffee shops, online purchases, tipping, and more.
Boolberry improves on existing CryptoNote coins by calculating transaction IDs using only the transaction prefix, excluding ring signatures. This allows ring signatures to be cut off from old transactions, reducing block chain bloat by 55-90% compared to ordinary CryptoNote coins while still proving transactions belong to blocks. Boolberry is designed to be more efficient and provide a more compact, faster synchronizing block chain for a better user experience.

Bitcoin is a peer-to-peer digital currency that uses cryptography to secure and verify transactions. Transactions are recorded on a public distributed ledger called the blockchain. The blockchain groups transactions into blocks that are cryptographically chained together and stored by all clients on the network. Miners compete to solve computational puzzles to validate transactions and add new blocks to the blockchain, earning new bitcoins as a reward. Over time, the reward decreases and other cryptocurrencies have emerged that implement variations on Bitcoin's core concepts and rules.
Blockchain technology involves distributing a central ledger of transactions among various nodes and miners. Transactions are first stored and then made visible through the ledger. This central ledger is then distributed among miners, who vote to validate new transactions and add them to the distributed ledger. Winners who validate transactions are rewarded. This process makes the ledger visible to all nodes, maintains security through digital signatures, and ensures invalid transactions are cancelled.

Bitcoin is a cryptocurrency that uses cryptography to control the creation of monetary units and verify transactions. It works by distributing a publicly available ledger of all transactions across a peer-to-peer network, achieving consensus on updates without the need for a central authority. Users can transfer coins electronically by digitally signing transactions with private keys.
Sidechains allow the transfer of assets between blockchains through a two-way peg mechanism. This mechanism uses cryptographic proofs to lock assets on one blockchain and unlock equivalent assets on another blockchain. It provides properties like atomic transfers without counterparty risk. There are challenges around complexity, potential for fraudulent transfers through deep reorganizations, and risks of centralization for sidechains with mining. Applications include experimentation with new features on separate blockchains and issuing new blockchain-based assets.

Metadata in the Blockchain: The OP_RETURN ExplosionCoin Sciences Ltd
With the addition of OP_RETURN outputs in version 0.9, it became possible to attach arbitrary pieces of information to bitcoin transactions. This turns bitcoin into a low-level communications protocol, just like TCP/IP, on which many new applications can be built.
Despite its powerful features, bitcoin is also limited, costly and inefficient compared to TCP/IP. After discussing which sorts of applications make this trade-off worthwhile, we talk about CoinSpark, a new open source protocol for enhancing bitcoin transactions, which makes extensive use of OP_RETURNs.

Bitcoin is a digital currency that uses blockchain technology to function as a decentralized peer-to-peer network without government control. It was created in 2009 by an anonymous founder known as Satoshi Nakamoto and uses cryptography and proof of work to validate transactions. Transactions are grouped into blocks and added to the blockchain through mining, where miners use computing power to solve cryptographic puzzles and are rewarded with new bitcoins. The blockchain serves to order and verify transactions through mathematical linking of blocks to prevent double spending. As more blocks are added, the blockchain record of transactions becomes more secure.
Bitcoin is a digital currency that uses cryptography and a decentralized peer-to-peer network to facilitate secure transactions between users. Transactions are recorded on a public blockchain ledger that is verified by miners who solve complex computational puzzles. When Alice wants to send bitcoin to Bob, she broadcasts an encrypted transaction to the network using her private key, and Bob can then verify the transaction using Alice's public key. Miners work to validate transactions by solving proof-of-work puzzles and adding verified transactions to the blockchain, receiving bitcoin as a reward. This process prevents double spending and allows for decentralized verification of ownership without a central authority.
Blockchain has gained lots of attention in recent years. Bitcoin and Ethereum are leading the race. Crypto currencies in spite of uncertainty and volatility are here to stay. Smart contract programming is the future for the Internet 3.0.

This talk will shed some light on why and how Blockchain applications are so critical and will discuss past events that led to fund loss or consensus failures due to bugs in critical parts of the code of Bitcoin and Ethereum applications.
Blockchains can be used as backends for applications by utilizing smart contracts and storing data immutably on the blockchain. While blockchains are not ideal for all use cases due to their expensive and slow nature, they enable building decentralized applications where security is important. Developers can build apps that interact directly with smart contracts, or provide front ends that reference blockchain data without needing their own servers.
Bitcoin is a cryptocurrency that was created in 2009 as a decentralized digital currency not controlled by any central authority like a bank. It uses cryptography to secure transactions and generate new units of currency. Transactions are recorded on a public ledger called the blockchain. New bitcoins are "mined" by solving complex math problems, and the total number that can ever be created is limited to 21 million. While bitcoin offers advantages like instant transactions and anonymity, it also has risks like high volatility and the inability to recover funds if private keys are lost.
Bitcoin is a decentralized digital currency that can be transferred between nodes on its peer-to-peer network. Transactions are broadcast and verified within 10-60 minutes, and are irreversible. There is a hard limit of 21 million bitcoins, which are divisible into smaller units. Bitcoins can be obtained by mining, which involves using computing power to solve cryptographic problems, or purchased on online exchanges.
This document discusses cryptocurrency and provides an overview of Bitcoin. It defines cryptocurrency as a digital currency secured through cryptography that allows for peer-to-peer transactions without an intermediary. The document outlines the risks of cryptocurrency including hackers, lack of protections, costs, and scams. It also describes how Bitcoin works, including how the blockchain records transactions in blocks to form a public ledger.

Distributed Ledgers, Blockchains, and Smart ContractsDusan Andric
This document introduces distributed ledger technology (DLT) and blockchains, including how they provide a decentralized and trustless alternative to centralized systems through consensus mechanisms. It describes how blockchains like Bitcoin use cryptography to record transactions in an immutable ledger, and how Ethereum generalized blockchains through smart contracts that run on a global decentralized computer. Smart contracts enable decentralized applications (Dapps) that do not require centralized user management. Examples of real-world DLT applications include stock exchanges, property registries, and autonomous organizations.
This document discusses different consensus mechanisms for distributed ledger technologies, including blockchain. It provides examples of proof-of-work (PoW), proof-of-stake (PoS), Byzantine fault tolerance (BFT), federated, and crypto-based consensus approaches. The document examines the properties of each, such as requirements, scalability, transaction finality, and decentralization. It questions whether consensus protocols and distributed shared ledgers are always needed, suggesting alternative approaches based on smart contracts and identity management without a shared ledger may be more efficient.
This document provides an introduction to blockchain technology. It defines blockchain as a computer code-based system that records transactions in blocks that are linked together in a chain. Each party in a transaction gets a copy to prevent fraud. Blockchain allows for immutable, transparent and auditable record keeping. The document discusses key factors like identity, transactions, blockchain and consensus. It provides examples of early blockchain use cases like Bitcoin and opportunities for industries like lending, real estate, and supply chain. It also covers scaling solutions and the current state and future of blockchain.
Blockchain is a distributed ledger that records transactions in chronological order in digitized blocks. Each block contains a cryptographic hash of the previous block, linking blocks together in a chain. The blockchain relies on a peer-to-peer network of computers to verify transactions without a central authority. Blockchain provides an accurate, permanent record of all transactions that have occurred on the network. Key features include decentralization, transparency, and security without the need for intermediaries.
Blockchain is a decentralized approach to solving the double spend problem of digital currencies without a central authority. It uses a distributed ledger maintained on many computers to record transactions in blocks linked through cryptography. This allows participants to verify transactions without trusting a central party. Blockchain addresses issues like single points of failure, censorship, and high fees by achieving consensus across a peer-to-peer network through proof of work and an incentive for honest participation in maintaining the ledger. Potential applications include cryptocurrencies like Bitcoin and programmable platforms for smart contracts.
Is Blockchain the practical solution to the all the trust and integrity issues ? Or we need something else?

Bitcoin is a well-known technological achievement in the digital age. More individuals recognise its benefits as it becomes more widely available and utilised.
Monero, a privacy-focused cryptocurrency, will be accepted by 45 musicians including Mariah Carey, G-Eazy, and Sia for holiday purchases. Monero aims to provide improved privacy over other cryptocurrencies by obscuring transaction amounts and the parties involved. This marks growing acceptance of cryptocurrencies by mainstream artists, though privacy coins like Monero remain controversial due to their potential for illegal use.

Litecoin Genesis Date - October 7, 2011
Founder Charlie Lee, a former Google and Coinbase employee.
Litecoin reached a $1 billion marketcap in November 2013.[
In May 2017, Litecoin became the first of the top-5 (by market cap) cryptocurrencies to adopt Segregated Witness .
Later in May of the same year, the first Lightning Network transaction was completed through litecoin, transferring 0.00000001 LTC from Zurich to San Francisco in under one second.
Cryptocurrency is a form of digital currency that uses cryptography to secure transactions and control the creation of new units. The first cryptocurrency was bitcoin, created in 2009. Cryptocurrencies operate on a decentralized peer-to-peer network using blockchain technology to record all transactions. Cryptocurrency mining involves using computers to solve complex mathematical problems to validate transactions and release new currency. While cryptocurrencies offer benefits like transparency and inflation resistance, they also present risks like market volatility and difficulty recovering lost funds.

"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.

4. Problems with Bitcoin
Onchain Problem
● Long Transaction
confirmation time
● Microtransaction is not
practical . (High mining
fees)
● Bitcoin is not scalable.
Every nodes verify every tx
Stats
● Only 7 transaction per
second.
● 250 bytes/tx
● 1 MB blocksize
5. At 1,200 transactions per MB every 10 minutes and 7
billion people do two on-chain transactions per
month, blocksize would have to be 5.7gb.
6. Solutions ?
Some Giveaways
● Maintain databases
records
● Sidechains
● Payment channels
Reveal
● Database requires trust
● Sidechains will end up with
2 tx
● Payment channels require
frequent transaction.
8. Brief
Intro
● By creating a network of payment
channels, it is possible to find a path
across the network similar to
routing packets on the internet.
● The nodes along the path are not
trusted, as the payment is enforced
using a script which enforces the
atomicity (either the entire payment
succeeds or fails) via decrementing
time-locks.
Payment channels
● Payment channels are based
on the idea of transaction
replacement to update the
state of an unconfirmed
transaction before
broadcasting it to the network.
