In this video we'll be going over the basicfeatures of Cardano.
CharlesHoskinson is one of the co-founders of ethereum. In 2015along with the Cardono Foundation, he foundedCardano.
Cardano is a platform composedof a settlement layer to handle cryptocurrencytransactions and a computing layer which is built to handlesmart contracts.
The idea here is to separate the accountingof transactions from the reasons why transactions are being performed.
The settlementlayer is the first layer to be developed by theCardona team. ADA is the native cryptocurrencyfor Cardano. ADA may be used to send andreceive digital funds on the settlementlayer.
Cardano allows for decentralizedapplications also knownas dApps which run directly on the blockchain rather than oncentralized servers.
Cardano featuresa proof of stake consensus algorithmcalled Ouroboros to validate transactions.
Ouroboroswas developed by a team of cryptographersfor multiple academic institutions. It is specificallydesigned to be modular, future proof andflexible as consensus algorithms evolve overtime.
In a proof of stakealgorithm, the participant who will create the next block israndomly selected proportional to the size of their stake in thecurrency.
As a proof ofstake algorithm, Cardano is not dependent onmining like proof of work algorithms like the one that bitcoinuses.
Time in Cardanois divided into epochs which are further divided intoslots. Slots are short time periods around 20seconds. Each slot has oneslot leader. Only the slot leader can create one and onlyone block in their assigned slot.
Transactionfees in a given epoch are collected in a virtualpool and distributed to these slotleaders.
Not all participantson the network are involved in choosing the next slotleader. In order to qualify, participants must hold aminimum threshold stake in the currency. If they quality,they are considered electors for the nextepoch.
Slot leader election is performed using a distributed method ofgenerating a randomnumber. The inputs are secret seeds generated by the participantsand the final output is an identifier for aspecific existing coin.
The owner of this coin will becomea slow leader.
All concepts that areimplemented in Cardano follow an academic peer reviewprocess.
An interesting feature in the pipelinecurrently is sidechains which will allow for greater scalabilityand new features without forking the blockchain.
Another isquantum resistant signatures which will prevent an attackfrom a quantum basedcomputeron the network.
Decentralizedapps or dAPPS are super hotright now. Enormous sums ofmoney and brain power are flowing into the sector,and very exciting things are happening.

Zcoin is a digital cryptocurrencythat puts financial privacy at theforefront where your transactions are completely untraceable.
It is built on the solid fundamentalsof the Zerocoin paper, one of the mostcited cryptography papers' today.
Bitcoinand most other cryptocurrencies are not really anonymous asall transactions since the founding of the coin arepermanently open for the public to view.
Researchers,governments and law enforcement agencies havemade significant strides in using meta data andpattern analysis to reveal the real world identities of bitcoinholders.
This is a serious privacyproblem.
Imagine having all of your transaction historyand spending habits revealed orworse, innocently editing up with coins that have beentainted from illegal activities.
Not only is yourprivacy at risk, your coins could be seizedor you could even be implicated in crime you didn'tcommit.
Other attempts to anonymize transactionsinvolving mixing transactions with other people'stransactions but this still means that the real transaction is somewhere inthere. And its privacy is reliant on howmany transactions you are mixing with.
These models still providean analyzable network map of links.
Zcoin uses zero knowledge proofs tomake truly untraceable coins.
You mint a coin byburning it up and generate a mathematicalproof that you burn it.
This proof allows you to redeem a newcoin with new previous transactionhistory. A clean slate.
The genius laysin that the proof doesn't reveal which coin youminted, thus there is no relationship that can be drawn from the coin that youminted and the brand new coni that you redeemed.
No history to analyze. No mixingrequired. Just truly untraceablecoins.
The browsers oftoday are broken.They have been overtaken by a barrageof sneaking and annoying ads. Trackers thatfollow your habits and cookies that build profiles and allother sorts of internet clutter that is taking precidenceover the content that you want to see.
In fact theseuseless bytes can take up to a whopping 50%of page load times with a third of it anxiously trying tolearn more about you.
To makematters worse, some ad blockersare even letting ads through when large advertisers pay them.
But do you really want a leaky ad blocker?
It's because of these very reasons that wedeveloped Brave. A new browser that kicks internetcrud to the curb and makes it faster, saferand better to surf the web than your currentbrowser.
With Brave, everything you need is built rightin.
We integrated technology that automatically blockstrackers, annoyingads and shields everything that can cramp your style and disrupt yourprivacy.
With it you can expect increased speeds almost2x faster on laptops and up to 4x faster onmobile. And unlike any other browser, Brave allowsyou to support your favorite publishers with automaticmicro payments.
It's a win win for you and your favoritesites.
To top it all off, Brave is open sourcebecause we truly believe it's our web and we needto fix it together.
Ask yourself thisquestion, do you want a web browser made for the internet of today?
If so, try Brave. It's faster.Safer and ad free.[silence]
Whatis Aeternity? Aeternity is a newblockchain platform that solves the issues ofscalability, privacy and transactionspeed.
Built by an experiencedteam, Aeternity is a next generation technologythat takes the lessons from big projects like Bitcoinand Ethereum.
What makes Aeternity different from otherblockchains?
Aeternity hasseveral unique features that make it different from otherblockchains. The technology aims to be ready formainstream adoption by providing three keyelements.
One, statechannels. Users interact with each other instantly andprivately. Your business interactions arekept off chain without having to exposeyour transactions or smart contracts publicly.
Thisalso keeps the blockchain light and robust for years.
There is no limit to the volume of transactions beingprocessed at the same time. Aeternity is lighteningfast.
Two, the hybrid proof ofwork and proof of stake system.Consensus is achieved by proof ofwork, this means that people can mine the tokens on almostall devices including smart phones.
This is truely decentralized mining.
The governancemechanism runs a proof of stake model basedon prediction markets.
Three, theoracle machine. Oracle machines allowyou to connect real world data to smartcontracts. Any publicly availabledata can be integrated such as electionresults, weather conditions, sportevent results, and commodityprices like gold and oil.
Thisopen up the field for major use cases.Think of financial applications,supply chain management, information markets,insurance andgaming.
Combining these three elements,Aeternity breaks the bottleneck to even further adoption ofblockchain technology with countless use casesand payment solutions, trade finance, andthe internet of things.
How isAeternity unique?
Aeternity will come with theessential applications available at the launch of theplatform, making it immediately useful.
Aeternity is working on educational programsto support businesses and developers to findtheir own use cases.
An incubator foundationwill support projects that build upon theAeternity platform.
Aeternity, a lightand secure platform to bring the blockchain technology to thenext level.

We'vealways lived in asmart world. Oursocieties, ourart, our ecosystems,our universe itself all made of vastcomplex networks designed for interconnection,growth and innovation.
That really started speeding thingsup.
The internet,originally conceived as a decentralized smartnetwork with no central authority, made itpossible to communicate directly all over theworld. But it wasn't built to evolve as itdid. And while our smartworld advanced, the internet stayed inthe past.
As it expanded, itsvulnerabilities become more serious,more prevalent.
Data. The life blood of the internet becamecentralized. Stored on servers ownedby giant corporations, easily found vulnerable toattack. Making our devices easilyhacked no matter how smartthey became.
Wedidn't lose the internet. Welost our internet.
Elastos is the moderninternet.
Elastos has rebuilt theinfrastructure of the internet from theground up, creating the world's first open sourcenetwork operatingsystem.
This is an operating system for the internet itself that iscompletely decentralized and it can beinstalled directly onto anything and everythingsmart.
Every person,every device, every business,every thing can be directly interconnected into onemassive global super computer. Each given their ownsecure identity that must be verified by theblockchain before accessing the network.
Enabling an internet of securityinstead of vulnerability.
An internetwhere central servers no longerexist. An internet where everyone owns andcontrols their owndata.
Simultaneously creating the world'sfirst platform for the secure internet anddata economy powered by theapplications of the future and the people who build them.
Because the platform is designed to run literally on anysmart device, developers can seamlessly write,install or integrate existingapplications onto Elastos using their ownsecure side chain allowing people andmachines alike to have direct exchange of the nextglobal currency.
It's laying the protocol, the foundation for the transportationindustry.
It's a combination of the technologiesI care deeply about.
Drones are oneelement. Blockchain is anotherelement. And distributed and trustedecosystem in a trustless environment.
DAV is an open transportation protocol. It enables us for the firsttime to create an open source peer topeer global transportation network.
This networkincludes anything and anyone involved inmoving people and objects from place to place.
Everyone on the DAV Network can discover services within thenetwork. For example riders can discoverdrivers and drivers can discovercharging stations. And developers can use the openprotocol to introduce their unique value to thenetwork in the form of routeplanning, machine learning, datasharing.
The opportunities this network can create areendless.
Looking a bit further down the road, the Dav Networkis an ideal entry point for thevehicles of the next decade which are autonomousvehicles on the ground, in the air and on the water.
The future is definitely autonomous.
If you had to summarize the future of transportation inone word, it's going to be autonomous.
Being able to do trueautonomous operations is what's becomingthe big push these days.
I canpredict that the autonomous world willexpand.
Once autonomousvehicles enter the market, you are no longerhiring the driver inside the car. You are hiring thecar. And this brings up a lot of interesting challenges.
For example, how do you get a quote and agree on atransaction with a car or with a drone?
How the vehicles compete for your business?
This is a completely newmarket and this is where theDAV protocol comes in.
It connects vehicles and users andservices, creating one big network so that wecan each have an entire network ofon demand vehicles at our disposal.
It alsoenables anyone to purchase equipment that is compatible with theprotocol and make it available on thenetwork in return for tokens.
For anyone that joins thenetwork, whether they are taxi companies,delivery companies or simply someone whoowns a drone, having a unified openprotocol means they don't need to be a multinational corporation to have utility.
The DAVprotocol connects them to a global network ofriders and drivers and vehicles anddevelopers and chargers.
The number of usefulcombinations within the network is exponential.
Theadvantages of a decentralized network like that isthat it allows true marketcompetition and doesn'tleave all the benefit and all the upside to one centralentity.
I firmly believe not a single entityhas all the elements to win. Nobody caneat alone. You have to share the pie.
Companies now have a choice. Instead of creating anentire network, an entire ecosystemfrom scratch, they can focus on theircore product and use the DAV protocol to become a part of anexisting network using completelyopen standards and without paying any fees.
The whole idea of theinternet was to break the middleman.And DAV is to the future oftransportation of what TCPIP was to theinternet.
The most exciting thing that Isee is the ability for DAV to be the key enablerof internet transport.
The DAV network isexpanding as more and more companies join. The DAVplatform is already being integrated into some of theirvehicles.
I believe no single technology is going tosucceed on its own. It's always going to be some mix oftechnologies.
Got to have a way [inaudible]transportation systems whatever they may be. So it's a combination ofgetting the players who do the best join in each of thosepieces to come in and work together.
I invite everyone to join ourgrowing community and take partin the futureoftransportation.

Evolution is behind all greatachievements. It has allowed us to gofrom ideas,tospace.
It has empoweredus to turn our dreams intoreality.
Todaydistributed ledger technology is the most sophisticatedphenomenon in the evolution in thedigital world. Itis thefuture.
Energi is the first cryptocurrencythat brings together some of the most powerfulideas in cryptocurrency.
Divisionbeyond just the technical infrastructure.
We are talking about something that is expansionary atits core and this goes beyond common features such as improving on transactionspeed, mass scalability, low fees.
Energihas all of these but the truly game changing propositionhere is Energi's decentralized governanceand treasury system. And that's a system that not only makes Energi selfsustaining but is also a self re-enforcing phenomenon.
That's theevolution of cryptocurrency.
Essentially it's a healthy growth snowballeffect. As awareness increases, so does its treasury economic power and sodoes adoption fueledby it.
An organization to beself funding, to be able to propel itself and pay its developers,pay its team and to do so in anaccelerating way where every dollar you invest in the organizationyields to a dollar of greater growth.
It's a positivefeedback loop.
The development, the marketing, the operations,the expansion... A self funded treasury that iswell directed is an incredibly powerful machine.
You arecreating no longer just a cryptocurrency but a living,breathing organization. Somethingthat can be as powerful as worldgovernance.
What is NEO? In this video Iwill be going over the basics of this cryptocurrency.
NEO was developed by a blockchainR&D company called onchain. Launchedin 2014 as Antshares, it was rebrandedas NEO in 2017.
NEOfocuses on innovating in the areas of digital assettransfer, smart contracts and digital identity verification.
The NEOplatform consists of two currencies, NEO andGAS both of which are capped at100 million units.
NEO is the pre minedcurrency which represents a share of the network. It cannot bedivided below one coin like most othercurrencies.
GAS is the fuel that drivessmart contracts on the NEO network. Deploying and running smartcontracts consumes gas proportionalto the computing power used.
New GAS is generatedwith each block. The amount generated isreduced by one token every 2 million blocks. Oncethe 100 million cap is reached, no new GASwill be created.
Unlike NEO,GAS may be sub divided into much smaller units.
Collected GAS is distributed to holders of NEOcoin based on their share of the network on a fixedschedule.
GAS for transaction fees aredistributed to bookkeepers also known asconsensus nodes in exchange for validating transactions on thenetwork.
Every NEO coinholder has a vote. Coin holderselect consensus nodes who validate transactions,create blocks and make decisions for the blockchainsuch as creating transaction fees.
Ifa consensus node is not acting in the interest of the network,coin holders can vote out that node.
Much likeethereum, NEO supports smart contracts. Smart contractsallow code to run on the network which imposeslogic and rules on the transferof funds.
Simple examples ofsmart contracts include locking funds untila package is delivered. Or releasing cryptocurrencyroyalties to a content owner each timea digital item is consumed.
One of thedifferences between NEO and ethereum is ethereum applications arecoded in a proprietary languagecalled Solidity whereas NEO applications support commonlyused langues such as java, C#and VB.Net.
Notable items in theNEO pipeline are NEO X which will allowtransactions across blockchains. NeoFSwhich will allow for decentralized storage offiles and NeoQ which will allow for a quantum resistantcryptographic methods within the NEOsystem.

Mobile apps are eating the world.By 2020 the number of smart phoneusers is expected to double. Gross revenueearned by the mobile app market is estimatedto reach $100 billion by the sameyear.
Yet the apps economy still presents three main challenges.
First advertising isinefficient. There are several intermediariesbetween the developer and the user, reducing transparencyand the potential return for developers.
Secondly,in app purchases are still not accessible tomany users and payment intermediaries increase overallcosts.
Lastly app approval is nottransparent. It's still difficult to confirmthe identity of developers and there is no universalapproach used by app stores.
Whatif there was a solution that could tackle these challenges byreinventing the apps economy?
[inaudible] hasbeen working on this for the past fiveyears. And today with smart contracts, we are going tounlock all of those valuesin app distribution and app monetizationfor the developers.
Thissolution is AppCoins, an open and distributedprotocol for app stores. Using blockchaintechnology and smart contracts, it's the new universallanguage of the app economy based on theethereum network.
How? Let's imagine that itall starts with an app developer investing incost per install advertising. With the AppCoinsmodel, advertising intermediaries are no longerpresent. The only margins [inaudible] are for the app storeand for the manufacturer.
If the user installs theapp, he or she will earn AppCoins that can be spenton in app purchases.
Furthermore with the App Coinprotocol, the reputation of the app developerscomes from their transactional historyacross stores.
All information is stored onthe blockchain, making app approval automated across appstores.
When it comes to in app purchases,AppCoins spent by users will also generate biggermargins for the developer since payment intermediariesare not present anymore.
In addition, users with nopayment methods can now receive AppCoins from otherusers and purchase in app items for the firsttime.
Disruption happens when we apply a new technologyto an old problem. The new technology here is theblockchain. The old [inaudible] financialtransactions inside the app store.
It's a problem thataffects billions of uses. And sometimes they don't even realizeand that's the challenge forAppCoins.
Overall there is an open, circular and sharedprotocol that creates a trusted environment for all parties.
For developers, a transparent and efficient way tomonetize their apps and build a reputation across appstores.
For users, a trusted environmentwith new purchasing possibilities and incentives to discoverapps.
For app stores, an app economywith a new universal language that ensurestrust without intermediaries.
Blockchain andcryptocurrencies bring our platform to the nextlevel. We always had this vision of a truly open and decentralizedplatform for apps distribution.And of course these technologies enable it.
We are nowvery excited that [inaudible] is going to use decentralizedtechnology and using the blockchainto really bring crypto technology to the huge userbaseof 200 million users.
