Cent is the income-generating social network
Cent is a social network that functions as an income source. So it's an alternative to employment. 

Hi I'm
 Bryan Colligan with AlphaGrowth and today we are here at San Francisco Blockchain week. I'm here with Max from Cent. Max how are you? Tell me about Cent.

Cent is a social
 network that functions as an income source. So it's an alternative to employment. It's a way of sharing knowledge and creativity within a userbase and directing or exchanging financial and creative value for each other in novel decentralized ways.

 are you at in your product life cycle?

Last Fall we pushed our beta
 live which is our bountry contract. A bounty you essentially make a request or ask a question of the network. Like I need a logo or review my paper I wrote for school.

You place a certain amount of
 money as a reward for doing that action.

Then the user base competes
 to give the best answer to that question. And then the answers are voted on and the money is given to the best answers.

Is this kind of like

We sometimes get called

That's not a bad thing. That's

It's cool.
 We have seen a lot of people.. We have users in over 120 countries now. A lot of people in rural India and Africa are using the service to answer people's questions and earn some amount of money. A few dollars per week but it's enough for them to fundamentally change their life quite a bit and we are scaling that up each month so that people are making more and more.

So you are here at San Francisco
 Blockchain Week. What are you trying to accomplish? 

We are doing our private sale of our upcoming
 token right now. Any investors that are accredited we are looking to meet. But also potential users, potential other technical collaborators. 

 all the conferences I go to, there are people I meet that I wanted to meet and something great happens out of it.

I think there is some aspect
 to life in just showing up..

You got to at least
 show up. 

The unknown

If people want to reach out to you and learn more about
 Cent, how can they do that?

They can contact me

 you are a creator or if you are any sort of other person who shares stuff online we are about to launch our second contract this week. 

 you can share something like a poem, song, video and you post it and people come along and think that's really cool. And they also think other people will also think that's cool. And what they can do is seed it with money.

That means they send a certain amount of money to a
 contract and half that money goes to the creator of the content and the other half goes to the seeders that gave money to that content before them.

So when you give money
 to something, you are going to get a steady stream of money from everyone that comes after you that gives money to the same piece of content.

It rewards both the creator and the early supporters of a
 piece of content financially.

So you are monetizing the viral

Yes. We are incentivizing
 people to discover, share and support creators in a way that's not relying on altruism. It's relying on selfishness which we think is an easier thing to rely on in the world today.

That's where Cent comes from,

It technically comes from
 incentivize and decentralized. But we like to think of every action on the network being incentivized.

In the
 first contract we talked about voting on what you think the best answers are. Each time you vote you earn a little bit of Eth just for doing that. So commenting and incentivized content sharing and pretty much everything.

That's my favorite
 part in the crypto world in general. How you can architect new types of behaviors. 

 has been super cool.

 a world where for every hard earned dollar you made, only 50 cents of it actually went into your pocket. 

Where at any given moment your bank account can be
 frozen or shut down.

 world where your clients' payments can be reversed because they got caught with their pants down.

 you it's a fantasy but for us it's a problem that only gets worse.

Companies like
 Paypal, Visa, Mastercard and others have systematically declined a service and redlined us, leaving room for shady companies to come in and fuck us with fees. 

But that will all change with
 SpankChain, the first in browser blockchain based micro payment processor and live video platform for the adult industry. With 5% fees or less, no charge backs and user anonymity meaning you'll get to pay less for the same great content while never having to give out your credit card or other sensitive personal information. 

But for us performers, SpankChain is not just decentralized
 infrastructure, it's a revolution. 

SpankChain gives us control over our finances, our
 content and our revenue.

For decades porn
 has advanced technology from Super 8 film to the VHS. Now it's time to take that leap forward again on our terms.

SpankChain's technology gives us the
 tools and the freedom to manage our own sites. Connect to decentralized marketplaces and control our future without those greedy corporate hands violating us. 

SpankChain is the key for near term cryptocurrency

Join us and
 together we can disrupt the adult industry, creating a better future for all. 

One that represents sex positivity
 and transcends the inefficiencies of legacy banking institutions.

Providing value through discussion
Welcome to a brief introduction of the Primas app. The first truly decentralized app that puts you in control.

Primas is a
 place where you make the rules and can openly share ideas with those willing to listen.

But how does it work?

 Primas is an idea publishing and sharing platform. On the home screen, you can browse through the latest articles and see what is trending in your groups as well as some others you might be interested in.

You can even write your own piece on your phone.
 Or on your computer using your web editor.

Groups are
 where Primas comes alive. Catch up with what's happening in the areas or industries that interest you. And support the verified original authors. 

 the value tab, you can keep track of your earnings and see the value of your contributions. Check out and customize your personal profile to fit your personality. 

Most importantly know that you are contributing
 to our movement to restore health to the internet. 
FansTime is a block chain based business in the e
The global entertainment industry is massive and growing. It's valued at over $300 billion worldwide. 

And we the fans, we really make it all

 many inefficiencies and challenges still remain in this industry. 

For example, 3rd parties hold all
 the control leaving value creators fighting an up hill battle. 

Furthermore their identities are often
 stolen and their hard earned reputation is ruined.

 many creators are exploited by their agents and platforms. 

And finally access and discovery is just not that
 easy for fans and creators alike.

So introducing FansTime, the first blockchain
 based fandom ecosystem aimed at solving all of those problems. 

It consists of three separate components. First,
 an individual intellectual property value system. Two, international crowdfunding platform. Three, global membership awards system.

So all of these come together to
 create a way to fairly value a creators' IP and empower creators and fans alike.

So you
 may be asking what will this look like for us fans and consumers? 

Well first
 there is going to be a celebrity time exchange where you can buy and trade time just like a token. And you can already access this via our app available on the Google Playstore. 

And then there is going to be
 an exclusive token exchange where you can support your favorite creators by buying their special tokens. 

Finally there is going to be a Fans Rights
 Mall where you can use your time and tokens to buy exclusive access and special products. 

All of this is made
 possible by the FTI token which is used for all ecosystem transactions.

Decentralized social network
[music] [music] 

There is a crisis occuring
 in the social networking world. Surveillance, algorithm manipulation and censorship are infecting the web at unprecedented levels.

For the
 first time in history, millions of users are abandoning traditional centralized social apps in favor of freedom based alternatives.

 is leading the way in this mass internet migration built on a foundation of internet freedom, reach, rewards and decentralization.

Instead of restricting
 your reach, Minds amplifies it.

Instead of selling your personal data,
 Minds protects it.

Instead of exploiting your contributions,
 Minds rewards you for them.

 are challenging one of the most complete monopolies in American life. You think you can provide an alternative?

We are
 building our own ad network, open source, anyone can inspect it and peer review it. It's fully transparent on the blockchain.

This is how things have to be. It can't be proprietary.

The integration
 of the blockchain allows Minds to add an essential layer of decentralization and transparency to the network.

On Minds you own tokens for your contributions
 which include generating high quality content, referring new users, maintaining an active channel, developing code and more.

Tokens can be used to boost your content for expanded
 reach, either from another channels' audience or the full Minds network.

By storing these transactions on
 smart contracts, the source of all advertising campaigns becomes publicly available and auditable on the blockchain.

Tokens can also be used to send
 payment to other channels either as a tip or in exchange for exclusive digital services.

Smart contracts enable
 content creators to autonomously own the relationships with their supporters or advertisers, eliminating any risk of demonetization or censorship.

There is a clear movement
 taking place, with the rapid rise of open source and decentralized technology.

Control of the internet has fallen into
 the hands of the few and it is time to give it back to the people.

The next big network is not going to be a centralized
 site. It's going to be a multitude of networks inter-operating so that it actually can't get censored. 

A community of developers - Building the future of

Giveth is
 the happy ending of the DAO. It's taking the same idea of putting a bunch of money in one spot for a cause but making it a non profit cause.

 has in the middle a simple GoFundme layer just like Kickstarter and all of these things where you are kind of a marketplace where you are trying to match people who have money and a desire to change the world to people who have the time and the plan to make that change a reality. 

The current charity system, there is this charity in the middle
 that kind of blocks the extra value that can be transferred. They take the money and route it over from these guys to these guys. But they don't get to connect the people. They are in the way.

I really believe that communities
 are what change the world. 

If we put
 these guys in the same chat room, then beautiful ideas will come out of it. It's not just about sharing the resources of money, it's about sharing the resources of ideas and time and effort and connecting everybody together.

We live in a world where you can
 tweet Donald Trump and yet you don't know who is using your donations for something.

It just doesn't make any

So we have this GoFundMe layer in the middle
 and above that we have a community layer, building a culture of altruism and experimenting with decentralized governance which is something that's really near and dear to my heart.

I really hope Giveth
 can be a playground for DAOs to come in and if you want to experiment with a decentralized governance protocol, you can actually test it by starting a charity.

Take your UI, take your smart
 contracts and then say we want to do the most good for homelessness. And beta test it. Air drop some money to all of your supporters and then let them have control over the donations and see how it works out.

Giveth is a playground for
 that. We have the Gofundme layer, the network of communities and there is basically a chat room. And the smart contract layer which is another thing we have a huge advantage of because Giveth was started by the White Hat Group and we have the best smart contract developers in the world.

One of the big
 reasons for that is we aren't trying to make money. We are really truly an altruistic loosely grouped set of hackers that are just trying to make the world a better place. 

We have no legal entity and that
 is by design because without a legal entity you can't make a profit.

Everything is
 happening in the smart contract realm. And everything is loose and fun and experimental. 
GitHub on video for developers
If you are a beginner looking to learn a new skill, online course sites are a dime a dozen.

What if you are past the beginner
 stage? If you are at the intermediate or advanced level, there aren't a lot of options out there for you.

That's the problem the
 education ecosystem solves. 

Professional development is an industry that is
 worth about $360 billion. But most of the online education companies that exist today are all competing in the beginner space.

That is
 why the education ecosystem is focused on people who have already passed the beginner stage. 

Our beta has connected 1 million professionals
 worldwide. And with our new education token, that number is only going to grow. 

The education tokens is an ERC20
 token which lives on the ethereum blockchain. That means it can be bought, sold and traded outside of the ecosystem just like any other cryptocurrency.

But our token
 exists primarily to power a new system of incentives which will reward everyone who brings positive value to the ecosystem at any level.

Learners will use education tokens
 to pay for their subscriptions, to donate to creators. To request specific projects or materials and engage in Q&A with project creators.

 return learners are rewarded for positive behavior like practicing with project materials and watching projects.

Similarly, project
 creators will be rewarded with tokens. The more view time their projects get, the more education tokens they receive. 

API creators who extend the platforms' functionality will be
 rewarded with tokens as well. So will users who find and report bugs on the system.

 tokens are also used for governance.

 example, holding education tokens will give users the power to vote on the future of the platform. Not just what projects are being created but the features that the development team implements. And what new project topics to support.

We have learned a lot from other token
 models like SteemIt which is a blogging platform that rewards its users with tokens when they write awesome content. And the more power the users have, the more they create projects which matches what viewers want to watch.

How do we make sure these tokens have
 value? To start with, the token is designed to have as much utility as possible in the education ecosystem meaning as long as people are using the network, they will need tokens. And as the size of the userbase grows, so does the demand for tokens.

To help further offset
 this, a percentage of all tokens spent on subscriptions annually are burned removing them from circulation and increasing the value of all remaining tokens.

 13% of all the tokens created have been reserved as incentives for project creators over the next three years. Our goal is to have 10,000 new projects created in the next 3 years.

We want to partner up
 with schools, libraries, colleges and other online education companies. 

Our mission is to be the place on the web
 for professional development. And our education token is the central part of that. 
Social media ecosystem
More than 3 billion people are engaged on social networks. The total content made on social network platforms is worth hundreds of billions of dollars.

It is the users who have developed
 these platforms through their content, posts, shares and likes. 

But the value created by users
 is distributed among company owners and shareholders. The content creators do not get compensated.

 this fair? No this is not a fair distribution.

 is why Foresting was born to change this. 

Foresting breaks the
 traditional platforms unfair system and provides a fair value distribution for users through blockchain technology.

The users are the true owners of the
 platform. For every act of posting, commenting, sharing and reading content, the user will be rewarded with PTON tokens.

Just as the seeds
 grow and become trees and forests. 

We make a forest through a new value system
 for a fairer world. 

Work 4 hours a day. Share
 every moment. And manage your life. 

Decentralized social news platform
The Sapien rewards engine is now live and automatically rewarding users with SPN for interacting with the platform.

These actions include creating high quality
 content, commenting and voting on posts. The more SPN a user stakes, the more rewards they earn.

How does this work?

Bloggers like Sam can be stake and earn
 SPN from the rewards engine for sharing his stories on the Sapien platform.

Kim leaves insightful posts
 or comments in any community she is a part of. Currators like her spend time voting on content, similar to ever other social platform. Except now all of them receive SPN for contributing to the ecosystem and adding value to the Sapien community. 

How are SPN rewards determined? By community

Introducing Charges.
 With Charges, the Sapien community controls the rewards engine. Each user is allocated a certain number of Charges per day according to their staking tier. If they think a post is valuable, they can give it a charge.

 day SPN rewards are distributed based on the number of Charges each post received. The more charges you get, the more SPN rewards you earn. 

As users all around the world begin adding value to the
 network by posting, commenting and voting on content, the SPN token becomes the fuel for a robust, tokenized social network that fairly rewards users for their efforts.

Stake your SPN
 tokens today and start earning with the Sapien rewards engine. 
Decentralized social media platform that rewards all content
Build, posts, photos, videos and stories are uploaded to mainstream social media every day. But very few profit from it.

What if you could be rewarded
 for posting on social media platforms based on the likes, comments and shares that you earn?

Introducing Mithril.

We created a whole new concept called
 social mining on the ethereum blockchain. Users can acquire Mithril tokens by simply using applications within the decentralized Mithril ecosystem.

Reinventing the Like
Have you ever published your creative content on social media? Have you realized no matter how many likes you get, the income all goes to the platform?

LikeCoin, a new cryptocurrency
 is here to reinvent the Like and help you generate the income you deserve.

Unlike other
 cryptocurrencies which use computational power to do mining, creators mine LikeCoin with creativity by making a new decentralized Like button and the unique LikeRank algorithm, LikeCoin traces content footprints and rewards all the creators in the collaboration. 

The more Likes your
 creative content receives, and the more derivative works it generates, the more LikeCoin you and your collaborators will receive.

Of course, you may also
 accept direct LikeCoin payments from readers and audiences. 

Remember, LikeCoin is promoting a movement to
 redistribute the income generated by content creation. We should get back the income that we deserve from the monopolized platforms.

Reinvent the Like, reward
 content through Proof of Creativity. 
Social messaging groups
Good day everyone. So today I am introducing a new app, the name is Nestree.

It's for different
 communities like you can find. Communities you belong to. We have ETH, we have [inaudible] group and [inaudible].

 on this app you can meet all the people that have the same interest with [inaudible]. They have phone [inaudible] different things.

The app is cool.

 found [inaudible]. So all these crypto communities [inaudible] you can find people with the same interest as you and get to talk.
