Blockchain and cryptocurrencies are emerging technologies that are still not fully understood. There are differing views on their value. Blockchain is a distributed digital ledger of transactions that is replicated across multiple computers. Cryptocurrencies like Bitcoin use blockchain technology, and their value comes from factors like production costs, scarcity, and utility. Ethereum enables decentralized applications and smart contracts through its cryptocurrency Ether. Altcoins have proliferated since Bitcoin, with some gaining significant value through network effects. Initial coin offerings have also raised billions for new blockchain projects.
Welcome to our channel,
A cryptocurrency (or cryptocurrency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions,
control the creation of additional units, and verify the transfer of assets. Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems. This channel was created to share news and opportunities related to crypto space.

Decentralized finance is a distributed financial system where there is no centralized governing body. Decentralized finance or DeFi applications utilize peer-to-peer finance networks. These networks are powered by decentralized and distributed platforms. The DeFi application ecosystem is vast and it includes various types of apps such as wallets, lending platforms, infrastructure development suits etc.
As there are many DeFi applications on the market, finding the top applications can be a difficult process. Here, we will discuss the top 5 DeFi applications – AAVE, Compound, MakerDAO, Synthetix, and MetaMask.
These are some of the widely utilized applications on the market. If you want to learn more about decentralized finance applications, then we have you covered. 101 blockchains feature a blockchain course that focuses on decentralized finance and will help you understand the working mechanism of this new financial structure.

A new movement is pumping oxygen into the cryptocurrency industry despite asset prices that remain 65% lower than where they were in late 2017. It’s called DeFi, short for decentralized finance—it’s the notion that crypto entrepreneurs can recreate traditional financial instruments in a decentralized architecture, outside of companies’ and governments’ control.
Let's take a look at what DeFi is, what tools are available out there, are they viable or just theoretical, who and how uses them, and most importantly, how can you use them (and if there is a reason for that).
Agenda:
- What is DeFi
- Open Lending Protocols (MakerDAO, Dharma, Compound)
- Decentralized Prediction Markets, Hedging (Augur, Gnosis)
- Exchanges (IDEX, EtherDelta, Binance DEX, Uniswap) and Open Marketplaces (OpenSea, Rarebits, Decentraland)

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. • “We believe Bitcoin may be the most important technology of this decade.”
-Andreessen Horowitz
• “It's not a medium of exchange, it's a medium of trading, so I can't see any intrinsic value.”
-Howard Marks
• “Stay away from it. It's a mirage, basically.”
-Warren Buffet
• “I would not invest. I need to understand it better. I think there's a lot of merit behind it.”
-Ray Dalio (2013)
• “I think the algorithmic approach to controlling the money supply used by Bitcoin and
other digital currencies being developed in Silicon Valley could go a long way to creating
a sound store of value.”
-Mathew Bishop, Editor, The Economist
• “… a currency is a target of speculation as opposed to primarily a means of exchange, it does
create some concerns for the user.”
-Raghuram Rajan (2014)
3. What is a Distributed Ledger?
• A distributed ledger (aka shared ledger) is a
consensus of replicated, shared, and synchronized
digital data geographically spread across multiple
sites, countries, or institutions.
• There is no central administrator or
centralised data storage.
• Blockchain is a type of distributed ledger.
5. What is a Blockchain?
• A Blockchain is a continuous list of records,
called blocks, a linked list that is built with
hash pointers instead of pointers.
• Each block contains typically a hash pointer as a
link to a previous block, a timestamp and
transaction data.
• A use case for a block chain is a tamper-evident
log.
6. What is in a Blockchain?
• Blockchain is just another type of database for
recording transactions.
• Data in a Blockchain is stored in fixed structures
called “blocks”.
• The important parts of a block are:
• Its header
• Includes metadata, unique block reference number, timestamp, and
a link to the previous block.
• Its content
• Transaction details, i.e., addresses of the parties involved and
the amounts.
9. Elements common to all Blockchains
• Digitally distributed across a computer network in
almost real-time.
• Uses many participants in the network to reach
consensus.
• Uses cryptography and digital signatures to prove
identity.
• Has mechanisms to make it hard(but not impossible) to
change historical records.
• Is time stamped.
• Is programmable.
10. What is a Cryptocurrency?
• A digital asset designed to work as a medium of
exchange using cryptography to secure the
transactions and,
• to control the creation of additional units of the
currency.
• Ownership of a Bitcoin is nothing more than other
nodes agreeing that a given party owns those
bitcoins.
11. Differences between Fiat Currency & Cryptocurrency
Cryptocurrency
No intermediary
Free float exchange rates
Unregulated
Untraceable
Less Secure
Not a Legal Tender
Fiat Currency
Backed by the Central Bank
Possible Intervention of Central Bank
Regulated
Relatively traceable
More Secure
Legal Tender
12. What is Bitcoin mining?
• Essentially the book-keeping service.
• Miners keep the Blockchain consistent, complete and
unalterable by repeatedly verifying and collecting
transactions in a group called “block”.
• Each block contains a cryptographic hash of the previous
block, using the SHA-256 hashing algorithm, which links it
to the previous block.
• In order to be accepted by the rest of the network, a new
block must contain a so-called proof-of-work. The proof-
of-work requires miners to find a number called a nonce.
13. What is Bitcoin mining?
• Only way to solve puzzle is to try nonces one by one and
hope that one succeeds.
• This proof is easy for any node in the network to verify,
but extremely time-consuming to generate.
• Every 2016 blocks (approximately 14 days at roughly 10 min
per block), the difficulty target is adjusted based on the
network's recent performance, with the aim of keeping the
average time between new blocks at ten minutes.
• Mining rewards has two components:
• Transaction Fees
• Block Reward (Currently 12.5BTC/XBT per block)
15. Weaknesses
• Bitcoins are not widely accepted.
• Wallets can be lost.
• Highly volatile.

24. Breaking Down Token Types
Token Type Function Examples
Traditional Asset Token To represent a traditional
asset cryptographically
USDT, DGD
Usage Token To provide access to a
digital service
BTC, ETH, BAT
Work Token To provide the right to
contribute work to a
decentralized organisation
REP, MKR
Hybrid (Usage + Work) To provide access to a
digital service and the
right to contribute work
FIL, ETH(with
Casper)

26. A fundamental approach
Three main sources of value driving a currency’s price:
• Production: High production cost.
• Bitcoin is produced via a virtual “mining” process, takes
exponentially more computing power each time a new cache is
mined. It not only requires specialized hardware, but
electricity to run and cool that hardware.
• Scarcity: Bitcoin (and most other cryptocurrencies)
are designed to have a fixed supply.
• Utility: “Use - cases”
• Golem – “AirBnB for your spare computing cycles.”
• Steem – Get paid each time someone reads or likes your post.
• SiaCoin - Decentralised private cloud service
• Augur – Platform that rewards for correctly predicting future
real-world events.
27. Ethereum
• An open software platform based on blockchain
technology that enables developers to build and
deploy decentralized applications.
• “Ether” can be transferred between users and used
to compensate participant nodes for computations
performed.
• Build new applications using “Smart Contracts”
• Trustless Crowdsale of Tokens
• Create a democratic autonomous organisation
• Dubbed as Web3.0
28. Smart Contracts on Ethereum
• Smart contract is just a phrase used to describe
computer code that can facilitate the exchange of
money, content, property, shares, or anything of
value.
• When running on the blockchain a smart contract
becomes like a self-operating computer program
that automatically executes when specific
conditions are met.
• Has features like no censorship, downtime, fraud
or third party interference.
30. What are ICOs?
• Analogous to an IPO, ICOs are means by which funds are
raised for a new cryptocurrency venture through sale of
coins instead of shares.
• ICOs are unregulated, startups use this to bypass the
rigorous and regulated capital-raising process required by
venture capitalists or banks.
• ICOs have now exceeded venture funding for blockchain
projects.
• Bancor raised $150 million.
• Tezos raised $232 million.
• Filecoin raised $200 million. (Pre-sale to Sequoia Capital,
Andreessen Horowitz, etc.)
• While, Tesla raised $226 million in their IPO.

Editor's Notes
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Censorship Resistant - no one can censor, alter or block transactions that they disagree with.
Push System – No third party involved, no security issues unlike credit cards.
Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met.
Scalable – Divisible down to 8 units.
