Understanding Proof of Work (PoW) and Proof of Stake (PoS) AlgorithmsGautam Anand
The document summarizes Proof of Stake (PoS) and compares it to Proof of Work (PoW). It discusses how PoS works by having validators stake coins to validate transactions and forge new blocks, earning transaction fees, rather than expending computing power like in PoW. PoS is more efficient and deters attacks as validators who validate fraudulent transactions lose part of their stake. While a 51% attack is theoretically possible in PoS, it would require buying a majority of the total coin supply, making it impractical. Popular blockchains that use PoS include NXT, BlackCoin and Peercoin.
Ethereum is an open-source blockchain platform that enables developers to build decentralized applications and smart contracts. It differs from Bitcoin in that it allows developers to build applications on top of its blockchain using its token Ether. Smart contracts on Ethereum use "gas" paid in Ether to execute transactions and are programs that automatically execute the terms of a contract. While smart contracts provide benefits like security, standardization and reducing the need for third parties, they also have disadvantages like being vulnerable to human error in coding and having an uncertain legal status.

Possible Areas of Implimention of Blockchain Technology in Libraries
Blockchain is a distributed ledger that records transactions in blocks of data that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. This design makes blockchains resistant to modification, as altering any block would require recalculating hashes for the entire chain. Blockchain technology provides a decentralized and secure way to record and share data across a network.
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.
Blockchain is a distributed ledger that records transactions in blocks of data that are linked using cryptography. It allows for a decentralized, peer-to-peer network without a central authority. Blockchain consists of blocks that permanently record transactions, addresses and wallets to store keys, transactions between parties, public and private keys to authenticate users, and hashing to validate data integrity. Blockchains can be public, allowing anybody to participate, or private, controlled by a single organization.
Blockchain is a distributed ledger system that records transactions in blocks of data that are linked together via cryptography. Each participant maintains a copy of the ledger with all transactions. New transactions are distributed across the network, validated by consensus, and added to each participant's ledger in a new block. The use of cryptography makes the records immutable and resistant to hacking or modification (paragraph 1). Blockchains are composed of blocks of transactions, a chain that links blocks, and a peer-to-peer network of nodes that maintain the complete record (paragraph 2). Blockchain allows peers to transact without a central authority by reaching consensus on transactions and maintaining an identical record of the ledger through cryptography (paragraph 3).
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.
Rohan provided an overview of how cryptocurrency works including key terms like blockchain, mining, decentralization, and proof of work. Blockchain is a digital ledger that records transactions across a network of computers. Mining is the process of verifying transactions and adding them to the blockchain to introduce new coins as a reward. Decentralization means control is distributed across the network rather than centralized. Proof of work is the consensus algorithm where miners compete to complete transactions. Rohan also discussed advantages like transparency and security as well as challenges like energy use and implementation costs.
Blockchain data structures and fundamentalCodium Club
The blockchain is a growing list of records called blocks which are linked using cryptography. So, here's a small introductory presentation to describe the basic fundamentals and data structure of the blockchain.
Blockchain is a distributed database that maintains a growing list of transaction records organized in blocks. Each block contains a cryptographic hash of the previous block, transaction data, and a timestamp. This creates a permanent, unalterable record of transactions that is distributed across a peer-to-peer network of nodes. Blockchain technology enables a decentralized system of recordkeeping that does not require a central authority and allows digital transactions to be validated and recorded in a transparent yet secure manner. It has applications in finance, healthcare, supply chain management, and more.
Understanding Blockchain: Distributed Ledger TechnologySuraj Kumar Jana
A complete introduction to Distributed Ledger Technology and Blockchain. Also, get introduced to Hyperledger, an open source permissioned blockchain framework by The Linux Foundation.
A blockchain is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data.
A blockchain is, in the simplest of terms, a time-stamped series of immutable records of data that is managed by a cluster of computers not owned by any single entity. Each of these blocks of data (i.e. block) is secured and bound to each other using cryptographic principles (i.e. chain).
So, what is so special about it and why are we saying that it has industry-disrupting capabilities?
The blockchain network has no central authority — it is the very definition of a democratized system. Since it is a shared and immutable ledger, the information in it is open for anyone and everyone to see. Hence, anything that is built on the blockchain is by its very nature transparent and everyone involved is accountable for their actions.

Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

property to another Internet user, such that the
transfer is guaranteed to be safe and secure,
everyone knows that the transfer has taken
place, and nobody can challenge the legitimacy
of the transfer. The consequences of this
breakthrough are hard to overstate.”
3. What is a blockchain?
● A blockchain is a chain of blocks that contains
information.
○ A block - a list of records/transactions/smart
contracts.
○ When a block is full →Its added to the network.
● It is essentially a digital ledger of transactions that
is duplicated and distributed across the entire
network (peer to peer) of computer systems.
4. What is a hashing function?
SHA-256
● Secure hashing algorithm
● Input X → Y
● f(index + pre-hash + timestamp + data + nonce ) = hash
● You can’t find X out of Y (one direction function).
● You need to ‘guess’ (=mine) the solution.
7. Immutable
Immutability means that the blockchain is a permanent and
unalterable network.
A collection of nodes:
● Every node in the network has a copy of the digital ledger.
● To add a transaction every node checks the validity of the
transaction and if the majority of the nodes think that it is a
valid transaction then it is added to the network.
● Without the approval of a majority of nodes no one can add any
transaction blocks to the ledger.
● Any validated records are irreversible and cannot be changed.
8. Decentralized
● The blockchain network is
decentralized which means
that there is no central
governing authority that
will responsible for all the
decisions.
● A group of nodes makes
and maintain the network.
9. Secure
● All the records in the blockchain are individually encrypted.
This adds another layer of security
● No central authority - BUT no one can update or delete
data on the network.
● Every information on the blockchain is hashed
cryptographically which means that every piece of data has
a unique identity on the network.
● All the blocks contain a unique hash of their own and the
hash of the previous block.
● The blocks are cryptographically linked with each other.
10. Consensus
● Every blockchain has a consensus to help the network
to make quick and unbiased decisions.
● Consensus is a decision-making algorithm for the
group of nodes active on the network to reach an
agreement.
● Nodes might not trust each other but they can trust
the algorithm.
11. Unanimous
● Most the network participants agree to the validity of the
records before they can be added to the network.
● When a node wants to add a block to the network → It must
get majority voting otherwise the block cannot be added to
the network.
● Every record is updated simultaneously and the updations
propagate quickly in the network.
● It is not possible to make any change without consent from
the majority of nodes in the network.
13. How Is Blockchain Used?
Cryptocurrency
○ Solana, Bitcoin, Ethereum and many
more.
○ When people buy, exchange or spend
cryptocurrency → transactions are
recorded on a blockchain.
14. How Is Blockchain Used?
Banking
● blockchain is being used to process transactions
in fiat currency, like dollars and euros.
● This is faster than sending money through a
bank or other financial institution.
● The transactions verified quickly and processed
outside of normal business hours.
15. How Is Blockchain Used?
Asset Transfers
● Record and transfer the ownership of different unique assets.
● Digital assets like NFTs (= a representation of ownership of
digital art and videos).
● To process the ownership of real-life assets, like the deed to
real estate and vehicles.
○ The two sides of a party would first use the blockchain to
verify that one owns the property and the other has the
money to buy.
○ They could complete and record the sale on the
blockchain.
18. ETH - The “merge” or POW to POS?!
● A monumental event for crypto
history.
● The network became
environmentally friendly (~0.5%
of the world electricity)
● Staking - happens on
cryptocurrency networks that
use the proof-of-stake model as
their consensus mechanism.
19. ETH - Built With Long-Term Sustainability in Mind
● Ethereum chain’s imminent
transition to a Proof-of-Stake
consensus mechanism will further
reduce the carbon footprint of
Polygon PoS by 99.91%.
● Polygon has committed to
becoming carbon negative by the
end of the year and has already
offset its network’s cumulative CO2
debt.
