Smart contracts are poised torevolutionize manyindustries by replacing the need for both traditional legalagreements and centrally automated digitalagreements.
But smart contractscan't access real world data such asdata feeds, APIs or bankingsystems due to blockchain's consensus technologies.
The way this problem istraditionally solved is through the use of blockchainmiddleware called an oracle.
Oracle's are defined as an agent that finds andverifies real world data andsubmits this information to a blockchain to be used insmart contracts.
But existingOracles are centralizedservices. Any smart contract using such a servicehas a single point offailure, making it no more secure than a traditionalcentrally run digital agreement.
Manycentralized oracles rely on [inaudible]or manual human input,slowing down the process and bringing in biglevels of trust.
Chainlink is a secure, cutting edge oracle middlewarenetwork that is fully decentralizedby being based on blockchain technology.
It allows smart contracts to accesskey offchain resources like datafeeds, APIs, traditional bank accountpayments, e-signatures, market data, weatherdata, sports scores, commodities trading, healthclaim data and anything else you canconceive of by chainlinkingmultiple data inputs to help eliminate any one point offailure.
The Chainlinknetwork provides reliable tamper proof inputs andoutputs for smart contracts on any blockchain.
By providing smartcontracts secure access to key data resources, Chainlinkallows other parties and actors to mimicreal world agreements that require externalproof of performance and various paymentmethods.
Really without Chainlink,smart contract platforms can't expand toofar beyond tokenization and theoccasional enclosed game.
Chainlink is thefirst technology that will be able to connect enterpriseblockchains, real world data and legacybankingsolving the oracle problem.
It can all be assimple or as complex as thesmart contract creator wishes.
Chainlink can help somany industries. For examplesecurities needing market data. Or insurancecompanies and supply chain companies that both needevidence of events and timestamps.
Remember high value contractsin the finance world would require a decentralizedoracle as it puts all the risk on the oraclerather than the smart contract creator.
The smart contractcreator doesn't risk losing money. The nodeoperators do.
These high valuecontracts don't like single points offailure.
Decentralization will give them confidence andefficiency.
The Chainlinkecosystem works on collateraland compensation using the LINKtoken.
This token doesn't represent equity in or anyownership of the company. Itrepresents a certain amount of usage of the Chainlinknetwork.
Node operators deliver thedata, APIproviders supply the data and smart contractowners need the data.
Soactors run a Chainlink node to stakeLINK as node operators. Two, smartcontract creators compensate nodeoperators in LINK.Three, API providers are compensated bynode operators based on the custom agreement and filters.
But if the API ispublic, no compensation here will beneeded.
30% of the LINKtoken supply has been held back to fund futher upgrades anddevelopment. 35% of the LINK token supplywill be going to node operators to helpkickstart the ecosystem.
Inthe future, if smart contracts usingChainlink take over just a few percent of the derivativesmarket or the API market, this cryptoasset will be a massive disruptor.
Chainlink has many outstanding partnerships andhas worked closely with SWIFTin development who have access to banking APIsand provide a messaging standard for more than 11,000 banksworldwide.
Zeplin OS is anoperating system for smartcontract applications.
Factom is a system for securing millions of[inaudible] records usingblockchain.
Accord and OpenLaware related to legal agreements with smartlegal contracts. And each themselves have big partnerships.
Chainlink is a professionalproject without the usual crypto hype andnoise. And there is a hive of activity on theirGithub.
It is rumored that mainnet iscoming soon and in the current testnetmany Chainlinks are live connecting with flight statusinformation, package deliverydata from Fedex, UPS, DHL.And market data from different crypto priceoracles.
The CEO has been doing moretalks recently too. And their communication has been slowlyramping up.
Chainlink is one of thevery few crypto assets that can really helprevolutionize and streamline so manyindustries.
I'mRichard Ma, CEO and co-founder of Quantstamp. The reason whyQuantstamp exists is because smart contracts are vulnerableto hacks and we make sure that they aresafe for everyone to use.
In January of2017, there were only around 10,000 smartcontracts. Today there are more than 8 millionsmart contracts and it's no longer possiblefor manual human experts to check all of these contractsindividually.
Quanstamp is really bringingautomation to the securityauditing industry so that eventually when there are billions ofsmart contracts, we can still make sure they are all safe.
Here at Quantstamp we are on a mission tohelp as many companies as we can to exploreblockchain in a secureway, so they can thrive ten years fromnow.
To this day Quantstamp has securedover $500M worth of smart contracts.
Richard Ma, CEO and software developer at Quantstamp.
Privacy has longbeen considered as our basic right and without beingaware we are rapidly losing it.
Weare being spied upon by our private data capturedand secretly used by private entities,criminal organizations and hackers.
Even our owngovernments are quietely passing laws that make it legalto spy on us without our consent.
Howeverit shouldn't bethis gloomy.
Today we can and we should fixthis.
GenerallyVPN is a great solution but todaymany simply trust some centralized VPN provider withoutknowing what really happens to their data behind closeddoors.
For many, that is a bigissue.
By 2019 the VPN market is estimatedto be a 70 billion dollarindustry. So how can we fixit?
What if you wouldn't have to bother about trustedVPN provider? Here comesMysterium network. The first decentralized VPNservice powered by open source technologyand ethereum blockchain and smart contracts.
Mysterium Network will offer us a newlevel of privacy not matched by currently operating centralizedVPN providers.
We invite you tojoin us in building this future.A future that respects ourprivacy.[music]

My name is Tim Holmes-Mitra, I'm the CTO of Glimpse.
HiI'm Alasdair Macdonald and I'm the CEO of Glimpse.
Glimpse is a privacy technology.We are looking at the ad tech industry and we are quiteconcerned about the different stories you hear in thenews all the time with people's data being violated withunknown and unseen actors.
We've seen a number of scandals that have happened over the lastyear whether it be Cambridge Analytica or the hack onEquifax.
We are really trying to solve that problem, its rootcause. That's by never giving away any of your data.
Our first industry we want to focus on isadvertising because that's where we think the biggest problemsare. Where that root cause needs to be addressed.
People thinkthere is a trade off, you can have targeted advertising or customerprivacy and with Glimpse you get both.
So you can haveprivacy and you can have targeted ads and that's why our protocol is sounique.
We applied to [inaudible] becausewe need to work with a public blockchain with ourproduct. That's essential, [inaudible] privacy.And for us ethereum is the real option that is productionready today.
So applying to [inaudible] gets usinto ConsenSys and connects uswith people who have experience already with buildingproduction ready technology that is working today on ethereum.
That'sexperience we need, it'll be vital for our project to draw upon thatto make sure it is a success.
Our experience at [inaudible]has been fantastic. The team itself has been really helpfulat connecting us with all the people we are really keen tomeet.
The validation to getting to [inaudible] itself has beenfantastic and then the further validation from the technology point ofview, from a privacy point ofview, business model, go to market.
All aspects of our business have been lookedat and refined during this whole process which has beenfantastic.
What's next for us? First we are going to go backhome and apologize to our wives, Christineand Phe, and say sorry for being in San Francisco for twoweeks.
Following that, we've opened our seedround and we're really keen to speak to hopefullymany people interested from this demo day.
Once we'veachieved that, then it's onto buildingthe beta.
So we've built a prototypeof what our application does and our technology. Sowe know it works. We know it's possible.
We've spoken to tons of experts now. So we know from abusiness and a technologically perspective it's viable.
Turning something from a prototype into a production ready applicationis a big task. That's really one of the things that we are going tostart concentrating on and getting into more detail.
Refiningour architecture, building it to scale, building itfor usability and all the challenges that come with that.
Additionallywe need to grow the development team aswell. So we'll need to bring in UI UX experts and we'll need to bring inmore engineers and all of the things that are involved ingoing from a seed stage company to acompany that can bring onclients.
I'm Pierre and I'm a multi purpose developer at Sensor.Link
I'm Yann-Ael, I'm the CTO at Sensor.Link
At Sensor.Link we are developing a software platform thatallows data authenticity forautonomous vehicles.
We appliedto Tachyon for the network mostly, the ConsenSysnetwork which gives us access to a lot of greatresources.
Our experience with Tachyon has been very positive.The Tachyon accelerator is really well structured.We've had access to a lot of great mentors and toa lot of exterior speakers that have helped us guide ourproduct and build the companyto what it is now.
The next step for us is leveragingthe power of a blockchain in a massiveway for adoption, for[inaudible] that are coming [inaudible]. So the nextstep is going for largescale adoption of our technology and integration.
Thenext step for us is to get customers,to massively deploy ourservices and targeting [inaudible][music][music]
Security and compliance platform
My name isJisu. I'm leading our team Sooho.We are the team focusing on providingsecurity and compliance platformbased on our comprehensive database.
I first cameacross Tachyon program when we were lookingfor a reliable partner targetingthe global market.
We sawTachyon could provide a greatrelationship global leaders from the blockchainmarket.
What I learned fromTachyon is what I expected. We expected a globalrelationship with the leaderof this market and we met a lot of people during theTachyon program from the ConsenSys mesh and outside of theConsenSys mesh.
They really work hard for me and wethink more about our company itself.
Forthe next step we are preparing forfinancial services based on crypto.
We already have security andcompliance services and a database. So now we aregoing to build riskmanagement services for cryptofinance.
Non-custodial anonymous transactions on Ethereum
Hi there today I'd like to show youa new dApp called Tornado Cash.
With this new dApp, you can nowmake private transactions on the ethereum network.
It's a non custodial, trustless and serverlessapplication that is workingright now in a public beta on Kolvan testnet.
The Tornado Mixer is powered byzKsnarks technology. So you can deposityour ether from one address and withdrawthis ether to any addresswith full untraceability.
So let's get started and see how it actually works.
Let's say I would like to depositone ether which I'mon the Kolvan test network which means it'sKolvan:ether
Inorder to work with this application,you need to have a web3enabled browser.You can install a chrome extension calledMetamask.
Let's make a deposit. When Iclick deposit, it says that I have to[inaudible] my node and if I lose my node I won't be ableto get my deposit back.
So it's very importantto store these nodessomewhere in a very securemanner.
So let's copy this node, clickthat I backed up the node and send the deposit.
So now we need to confirmthe transaction usingMetamask. And then we needwait when this transaction is going to bemined.
Alright,our statistics has been updated andwe can see that our anonymityset has been increased by one user which means it was ourtransaction.
So right now wecan check how we canwithdraw such transactions to any otheraddress.
So let's saywe copy and paste the same nodethat we have received from ourdeposit. And we can see there is a little warningthat says there has been zero depositsafter our deposit.
Whichmeans it's not recommended to withdrawimmediately. It's better to wait at least fivedeposits after your deposit.
And then wecan choose which withdrawalmethod we want to use. One ofthe options is a relayer,it basicallymeans you can withdrawto any address you want without having ethereum on youraccount.
And the relayer is going to take a little fee just topay for the transaction fee.
Let's say wegenerated a newaccount. This address doesn't have any etheron it and I can specify the recipientaddress and click the button towithdraw.
So nowwe are waiting for thegeneration proof. OK, that wasreally fast. So you can now use as the zKsnarkproof has been successfully generated.
So now please click confirm to initiatewithdrawal.
Once I click that,that's going to send this proof tothe relayer server. So the relayercan make a transaction and withdrawyour ether. -- As we can see on our blockexplorer,we should be able to receive oneether minus the transactionfee. That's how much is going tobereceived.
So we have just received0.99 ether usingthe awesome Tornado Mixer.
Today there are 3.5billion people using the internet in the world, and that number willgrow to 5 billion in 2022.
All these people have an internet connection that is paidfor but they don't use it24 - 7.
Did you know that almost 90% of the internet broadbandwhich is already paid for remainsunused.
Privatix will allow everyoneto sell this spare bandwidth and get paid for it incrypto. Real money.
With zero investment oreffort, you can make your idle resources generate profitwhen you are sleeping.
Stop, who will buyit? Where will the money come from?
That is simple and genius.
People's internet connection andbandwidth is highly demanded by businesses who needthis scarce and high cost resource to build or sustain theirproducts.
Examples?No problem. Here is one of the most obvious examples ofservices which can be built on Privatix'snetwork foundation.
DecentralizedVPN services, 100% anonymous, fast, cheap andunblockable. Based on blockchain that can eliminate themiddleman in the face of centralized VPN service providers.
Real anonyimity and cryption, worldwide coverageand low prices, because the paymentgoes directly to exit gatewayowners.
Blockchain CDN, the potential killer of AWS and Akkamai.Or residential IP addresses and proxymarket with millions of exit pointsworldwide.
Anti censorship SDK.Even monetization solutions for appdevelopers.
Today there is no solution which can connect buyers withsellers and ensure their mutual benefit. Butblockchain is coming to help.
Based onethereum blockchain, Privatix will build a peer to peerVPN network with 1000s or even millions ofparticipants. This network will have its own crypto economyand built in bandwidth marketplace.
OurPrivatix network concept is patent pending in theUS. Once it is developed it can solve the biggestproblems the world wide web is facing right now or in the nearfuture like internet censorship.Cyber security. Privacy protection and easyto use encryption for everyone to speed up the wholeinternet by using idel worldwide broadbandresources.
Join us because our team has aproven record of previous projects, significantexpertise and experience in cyber securityand in the privacy protection area.
As technologyadvances, hackers are continuously evolving their methodsand yet due to traditional penetrationtesting and paper [inaudible] models, strongpenetration testing solutions have remained unattainable forSMEs leaving them highly vulnerable.
The time has come for that to change.Introducing Buglab, the affordable, versatileblockchain solution for asset pen testing.At its core, Buglab provides two distinctplatforms designed to help SMEsacross the globe navigate the threats of thedigital space.
Buglab contests and thevigilante protocol.
With contests, expert security researchers competeagainst one another in competitions launched byclients. Here is how they work.
The scope isdefined and the contest begins. For pentesters, it's a race against the clock to scour theclient's infrastructure for vulnerabilities.
Submissions aretimestamped on the blockchain, ensuringtransparency and immutability which Buglabtriages, ranks and scores the severity of identifiedvulnerabilities.
Real time reportingallows clients and pen testers to work onrepairs immediately. When the content ends,pen testers are ranked according to their cumulative discoveries.To safe guard their identities, they are then rewardedby the BGL token.
Meanwhile clients receive a comprehensivecontest report. In addition to pen testingcontests, Buglabs vigilante protocol provides an avenuefor whitehats globally to share their own vulnerabilitydiscoveries.
Upon identifying vulnerabilities,white hats connect with Buglab who thenpartners with CERT and CSIRTsall over the world to verify the findings. After whichthe company at risk will be notified.
Once the companyfixes the identified vulnerabilities, the white hat isautomatically rewarded using smartcontract with BGL tokens from the vigilanteprotocol reserve.
Finally the companies are alsoinvited to directly reward the white hat and launcha Buglab contest to take precautionsagainst further potential data breaches.
