Stability for the blockchain
While DAI is a stablecoin that tracks the value of the USD, Maker has a variable value. It was created to support DAI in a number of ways.

First the MKR
 token enables governance of the whole system, giving its holders voting rights on proposals. 

Second, while CDPs are expected to remain
 over collateralize, if mistakes or unforeseen events occur that cause a CDP to fail, new MKR tokens will be created covering the losses so that holders of DAI can have confidence in the value of their token. 
Now more than ever blockchain technology is revolutionizing the landscape of the global economy.

Despite the
 inertia and conservatism of key players, the most visible changes are happening within the financial industry. 

 introducing Blackmoon crypto. 

 platform for asset managers to create and manage tokenized investment funds.

We provide the technical and the
 legal framework that bridges the crypto and real world economies.

 framework enables participation in traditional investment markets from within the blockchain realm.

 Blackmoon crypto platform, the investor's rights are formalized and protected using smart contracts on the ethereum blockchain.

Tokenized investment funds can
 easily be created in the Blackmoon crypto platform and invested in traditional offline assets as well as in the blockchain economy.

We see protecting
 the interests of the crypto society as a major responsibility. By maintaining close contact with regulators and financial institutions, we hope to ensure recognition of the crypto world as a new reality in the modern economy. 

Join us in bringing
 crypto to the real world. Participate in the distribution of Blackmoon crypto tokens. 
We live in a world full of contrast. Technology evolves at breathtaking speed yet our monetary system and financial services industry have failed to keep up with the accelerated pace.

Traditional asset trading is a
 prime example of an industry that has been left behind. It is complex, clearing and settlement take three days. It's extremely cost intensive due to the number of fees that need to be paid.

It's exclusive due to
 artificial geographic trading restrictions such as the need for a bank account.

Cryptocurrencies on the other hand
 are easy to handle. The fees are minimal and the barriers to trade are non existent. 

However because of market volatility,
 investors can see their portfolios dissipate with in a matter of weeks. Plus the limited acceptance of digital currencies in the traditional economy leaves very little ways to diversify risk.

Through the use of
 smart contracts, Brickblock is creating a platform that allows users to seamlessly invest into real estate and ETFs and cryptocurrency funds. 

When you buy an asset
 on Brickblock, it's first stored in a digital trust fund and kept there for the life of the trade meaning your asset tokens will always be one to one backed by real assets.

After full
 clearing and settlement, a token representing the equity of the asset is then issued through the Brickblock platform and can be stored in most crypto wallets.

Investments that were usually kept with a bank or a
 broker can be secured on a phone or computer and carried with you at all times.

By bridging asset investments with the
 blockchain, Brickblock will create a system that empowers everyone to seamlessly invest in global funds.

A system
 where order and issuing fees can be reduced to a fraction of the usual cost.

Where counterparty risk can go down
 from 3 days to mere minutes. Where everyone has access to real world assets and can carry them within their pocket.

If you want
 to help bring to reality the next phase of investment evolution, then join our whitelist and support Brickblock. 
Platform for legal and compliance workflows
Financial markets drive the global economy. They bring enormous wealth of opportunities, attracting businesses, traders and investors all around the world.

However these markets
 are divided by complicated rules and long wait times while central authorities collect hundreds of billions of dollars in service fees every year. 

Blockchain technology has the potential to
 shatter these barriers, making finance more transparent and autonomous while creating more competitive markets.

But today's crypto market is a bit
 like the wild west. It's young and highly disorganized.

For the blockchain to become a global supermarket
 of financial instruments, it will need a proper ecosystem of qualified services. 

Abacus is a self amending open
 protocol that allows anyone to create financial services and instruments on the blockchain.

Our community
 provides a plethora of services, such as compliance checks, identity verification, risk assessment, appraisal and many more.

Leveraging the strengths of the blockchain,
 the Abacus Protocol enables smart contracts to represent a wide range of financial instruments and marketplaces.

Abacus enables companies to create fungible
 and non fungible tokens with peace of mind. Staying on top of the latest regulatory guidelines, the protocol also runs on multiple blockchains, supporting a wide array of tokens and enabling an entire economy of new tokenized financial instruments.

Our mission is to build the
 decentralized financial ecosystem of the future and allow anyone with a creative financial idea to access trillions of dollars in financial opportunities.

Ethereum margin trading exchange
[silence] [silence] [silence] [silence] [silence] 

Hey guys, I'm Antonio from
 dYdX. A decentralized exchange for derivatives and shorts. 

So at dYdX we are
 building an open protocol that allows short selling and options on any ethereum based token.

The protocol is totally open and free to use
 and allows the instruments to be taken in a peer to peer and trustless way.

In addition we are building
 a relayer which is sort of a centralized website where people can go to actually trade the shorts and options on the base protocol.

Finally we don't have our own token but
 you can use dYdX to short everyone else's token. 

 next we are going to go through a demo of how dYdX actually works.

As you can see
 it kind of looks like a centralized exchange that allows market, limit orders, short sells and loans for the shorts. 

We are going to go through how a short actually works.

 you can see it's super simple, all you have to do is plug in how much you want to short, click OK, approve it in your wallet and that's it, you are short some token now. 

So then your position can be open as long as you want.
 And later you can come back and close your position and you'll make money if the price went down or you'll lose money if the price went up.

Here we are going to close the
 position, approve it in our wallet and then wait for the transaction to be mined and our position will be closed and we'll have made whatever profit we made on the trade. 

Next we are going to take a quick look at the transactions on the blockchain.
 This is the transaction for opening a short sell. How it works is the tokens are taken from the lender and sold immediately to the buyer and then some margin deposit is taken from you the short seller.

And this is the
 transaction for closing a short. Basically the tokens that were lent by the lender are always given back to the lender plus some interest fee.

 then the short seller makes the profit minus the interest fee.

Where we are at right now is
 we started in August and we've released the whitepaper and also have that private beta which is what you just saw live on the testnet. 

Next steps are to go through security audits which will hopefully be
 done by March and then we are targeting an April launch for the short sells plus spot trading. 

Then we are going to add in options
 later and hopefully that will be around July. 

So that was just a really clear work through of
 how dYdX works and as you can see it's live on the testnet now in a private beta and we'll probably open it up at some point in the future.

Thanks for
 taking a look. I'll be around the rest of the time if you want to come talk to me. 

Email is
 and we are hiring. Reach out to me if you are interested. 
Decentralized Finance and Cryptobanking
[music] [music] 

Modern financial systems have enabled rapid economic
 expansion and improved the lives of billions. However their centralized design cannot meet today's growing financial needs.

 Aurora. The decentralized crypto banking and financial platform.

By combining
 a real time decentralized asset exchange with the world's first decentralized bank, Aurora creates a stable financial platform that anybody, regardless of geographic location or status can use to secure their financial freedom. 

Here is how.

IDEX, Aurora's
 hybrid decentralized exchange allows any ethereum crypto currency to be traded securely and in real time. Traders can place and fill multiple market orders at once and cancel orders instantly without incurring gas costs.

 operates hand and hand with the Boreal, Aurora's price stable crypto currency.

Backed by a combination of
 crypto currency reserves and debt, Boreals are accepted at their target value for payment for IDEX trading fees and eventually for other services within the growing dApp economy. 

IDEX and the Boreal will migrate to operate on
 Snow Globe, a side chain protocol that enables multiple high performance exchanges to share liquidity.

Snow Globe will expand the number of exchanges
 backing the Boreal and serve as the foundation that enables Aurora to scale to the level of the current financial system.

As Boreal usage
 grows, Aurora will begin to issue loans in the currency through the first crypto bank.


Blockchain based identity and credit systems
 will allow for accurate risk assessment, enabling decentralized capital to bring a digital banking solution to consumers in all parts of the world.

Aurora will be the first fully decentralized crypto
 banking and financial platform where anybody in the world can trade, borrow or grow their wealth securely and in real time.

Join the
 evolution of finance today. 
Invest, own, and trade security tokens.
If you're watching this, you are among the 2% of people that understand that the future of trading assets is going to look very different from how it looks now.

 real estate for example. Big chunky illiquid investments dominated by a select few with a tremendous amount of money being redirected to middlemen. 

That's going to change.

 Blockimmo, a blockchain powered real estate platform. Our platform enables investments in properties, fundraising for development projects and traditional private property exchanges.

For all three we cut out middlemen,
 resulting in an efficient and decentralized system so that the value stays between the key parties involved. 

You are probably thinking blockchain is crypto, right? It's all just
 speculation and talk of innovation without any real execution.

Wrong. That's where we
 come in.

Blockchain will change every area in our
 lives. We are coding the future. We are leveraging the technology. We are investing in our skill set every day with simplified and streamlined real estate. With a system of smart contracts on the ethereum blockchain, the foundation of our software stack.

 enables a simple, robust platform. 

Security is a top priority. We've architected and
 implemented each layer in our stack with our users safety in mind. We've battle testing our software with a series of external audits and an on-going bug bounty.

We stay curious. We
 train our brain every day and hire only a select few. The ones with the right fundamental right set.

Even so, we are able to grow exponentially
 through smartly executing technology.

Our aim is to bridge the technology gap between blockchain and
 the user and our strategy is simple.

Constantly iterate and ship.

By improving and
 simplifying the user experience on a daily basis, we bridge the tech gap and deliver true value to our users.

Within the blockchain
 ecosystem, it's time to get shit done and that's exactly what we've been doing.

We will keep building and improving the awesomeness of the
 technology. But it's going to be product first.

So this is really happening? Yes.
 Do you think you'll adopt when the time comes?

 again. The time has come and you can be part of it today.

Join us as a team member, as a client,
 as an investor or as a partner.

Digital gold standard
What if I told you there was a new digital coin that married the best aspects of current cryptocoins with the safety and stability of gold, the oldest continuous store of value known to humanity. 

Cryptocoins in their current form have two major
 drawbacks. One, volatility. You simply cannot reliably transact with a coin that has more short-term price volatility than competing traditional options.

Centralization. If you
 have a single point of failure such as a big depot where a large amount of coins are stored, criminals will find a way to exploit that weakness, hack through the security and steal the coins.

But what if you could eliminate that
 price volatility by tying a digital coin to an asset that has real, stable and historical value like gold.

What if that gold digital
 coin was traded person to person without any centralized intermediary like a bank or other institution in the way.

You would have created a
 revolution in digital coins.

This is
 exactly what Digix has done.

Digix has
 taken all of the innovative realities in a current digital coin, the blockchain, transactional privacy, minimal transfer fees and backed it up with the world's oldest and longest standing store of value, gold.

With the Digix
 tokens, you own actual physical gold stored in a vault in Singapore, one of the world's safest and most private locations in the world.

You can redeem
 your Digix tokens for physical gold any time you wish. Or you can trade your digital gold backed Digix tokens on the Ethereum blockchain for goods, services or other digital assets. 

And because Digix tokens are transacted
 person to person, there is no centralized depot for criminals or hackers to exploit.

So if you have a
 family member that you want to send money to, Digix tokens give you a way to send value to them that can go across the world without any bank or other intermediary getting in the way.

Or if you have a business online or you are
 an artist selling your art work, with Digix tokens you can accept payment from anyone, anywhere in the world without the hassle of dealing with banks or paying their bloated fees.

Digix tokens are the next evolution
 of digital coins, marrying the best of the new way of sending value person to person, anywhere in the world, instantly without any intermediary. 

And with the stability and peace of mind
 of the world's oldest currency, gold. 
Borrow/Lending decentralized

On this video we are going to be talking about

Compound.Finance is a borrowing platform allowing you to
 lend and borrow cryptocurrencies in a fully decentralized manner.

The platform allows you to
 borrow regular cryptocurrencies like BAT and stablecoins such as DAI which are pegged to the USD.

We'll be taking a look at their current platform with
 Mike and also possibly doing some borrowing of our own.

Let's go take a look at Compound.Finance
 with Mike.

So now
 we are going to talk about Compound.Finance 

This is a lending platform.
 It's a lending and borrowing platform that has its own decentralized protocol for holding onto assets and letting people borrow.


As you see it's a dApp,
 so you connect with Metamask. This is the app and usually when you sign in... This message isn't up here... 

 they had an issue where there was a vulnerability found by a community member. They are swapping out some of the contracts and looking at auditing some of the relationships that happen between the frontend and backend.

Have you
 earned interest on the money? 

I have.

So we lent $23
 originally. And on a variable 9.5% APR we have made 5 cents. 

When did you do this?

 couple weeks ago. 

So you can earn money over time lending out
 ETH or DAI in this case for you to other people. DAI is basically just dollars. You lend it out and you earn interest. 8% a year.

But you said before it
 was more.

Before it was
 around 15%. It changes, it goes up and down.

Based on what?

It's based off of the collaterlization
 that's being supplied as well as the price of the underlying asset.

 reminds me of MakerDAO.

 has a lot of common pieces.

The interest is super
 simple. Easy to use as well. I wish the borrowing activity wasn't paused so you could look. But you can go in and check out the data. 

Either send in to one of the collateralizers
 or borrow.

I think it's really fascinating
 because with traditional assets, you put your house up as collateral. But they have to do a lot of research around who has liens on that house etc. And you can basically come in and take [inaudible] something like security tokens.

 it. It's immediately authenticated through the blockchain like it is now.

Now I
 take out money, I borrow a certain amount and if I don't pay it back in enough time or something happens to the value of my house, then I get liquidated etc. 

That's how CDPs work. I think the more platforms that come out
 like this is really fascinating. The more we can get real world assets on the blockchain that are verified, the cooler platforms like this can become. 

 the rules won't change. It's not like somebody in some part of the basket down the line changed how their particular financing is working and it has this huge affect that changes what you are borrowing and one day you go to consolidate your loans and everything is messed up because somebody in some basket messed something up.

 it is blockchain, because it is a smart contract, the logic governing it stays the same. The rules don't change.

 are very much at an incubation stage. As we see here, the borrowing is down now and there is a bit of chaos here because there was a vulnerability in the smart contract.

That can happen as
 we are at the very early stages. I think when it matures it'll be really awesome.

What is
 the risk modeling? Instead of [inaudible] now we are dealing with technology hazards.

What happens if the
 core protocol has an issue? Who takes care of making people whole?

There is no human. It's all

Aside from being terrifying,
 it's really cool. 

 this is Compound.Finance 
Stablecoin pegged to USD
Money, we all use it, but what is it? We carry it around and exchange it for the stuff we need. And keep some back for a rainy day. We trust that one piece of money is the same as any other. And we hope that what we have today is not worth less than it was yesterday.

 money having to perform so many different functions, it's no surprise that it has taken on so many different forms.

As money evolves, we
 arrive at bitcoin. Created without a central authority is less vulnerable to issuance corruption than standard fiat money.

With this unique
 commissionless nature, it redefines what money is and what it can do. But it's not quite perfect money.

Bitcoin's fixed supply
 creates a speculative investment and with that a money with a high degree of volatility. 

DIA is a solution to that volatility. A cryptocurrency
 using collateral to back its value and interest rate mechanisms to stabilize its price. 

DAI is created by locking collateral with
 Maker, a decentralized platform on the ethereum blockchain.

 currency collateralization and interest adjustments ensure DIA has low volatility against its external reference point, the US Dollar. 

DAI, the next step in money

Instant crypto-backed loans
Meet Bruce and Tom. Like many modern people, they've both invested in cryptocurrencies. 

They just came across this last minute travel deal but
 it expires in 30 minutes. The problem is, none of them has the cash to pay for it.

Next week bitcoin might surge 20%.
 I really don't want to sell my crypto right now and lose all potential profits. Plus I've got to pay exchange and withdrawal fees not to mention the heavy income taxes. 

Even if I sell my coins now, the travel deal will be gone by the time
 I get the cash.

Bruce, what about him?
 Well Bruce already paid. How did he get the cash so quickly?

It's simple. Bruce
 just got an instant crypto backed loan from Nexo. The world's first instant loan secured by crypto assets.

Nexo is powered by Credissimo, a leading
 European fintech group.

Here is how it works.
 You place your crypto in your Nexo wallet on the blockchain. And without any credit checks, you get instant cash from Nexo. No exchange fees, no hidden fees, no taxes.

Best of all you retain all the
 profit from your crypto.

With the
 flexibility of your Nexo loan, you get cash to spend whenever you need it while keeping your crypto.

Who would you rather
 be? Bruce or Tom?

Join Bruce and enjoy your crypto
 wealth today without selling your assets.

Unbank the banked
OmiseGO is one of those projects that so many people are excited about. 


We are building a decentralized
 exchange network that's going to connect different payment systems together. 

 [music] [music] [music] [music] 

My name is
 Casima and I'm the director of engineering for Plasma here at OmiseGO. 

So what is Plasma?
 Plasma is basically an architecture framework for scaling blockchains. 

The goal is to be able to do billions of state updates
 per second on this network which is publically accountable on the public chain.

The nice thing about Plasma
 is it doesn't require any changes to the ethereum base layer. So pretty much anyone can spin off a Plama system whenever. 

This version is working on the official
 [inaudible] network that is created by OmiseGO. It supports ERC20 tokens. 

What do you do have OmiseGO?
 I'm taking care of the [inaudible]. That sounds like a big responsibility. Yes. 

 we are OmiseGO the big core challenge we are trying to address is financial inclusion. How do you make payments through wallets available to everyone in an easy to understand manner.

I think what's missing a lot in the blockchain
 space is how do you just make it accessible to normal people? And I think [inaudible] in terms of the identity and KYC and key management, those are all going to help address a lot of [inaudible] issues. 

 looked at OmiseGO last summer when I saw that Vitalik was meeting with the Central Bank of Thailand. The more I learned about OmiseGO, the more the [inaudible] pervious work and really resonated with me.

Decentralized trading on the Ethereum blockchain.
Market Protocol, redefining the financial landscape through blockchain technology.

Typically investors and
 traders have two goals, to generate wealth and protect the wealth they already have. But most people around the world can't access high quality access, hedge or manage risk or invest safely or build wealth resulting in unnecessary risks and lost opportunity. 

Market Protocol tackles this
 problem head on by enabling digital tokens that track a variety of assets. With it a person in the Philippines could invest in the US stock index. Someone in Venezuela could access the reserve currency. Or a speculator could profit from a decline in Litecoin or Monero.

Our technology
 incorporates the security, transparency and accessibility of the ethereum blockchain, removing centralized intermediaries and market inefficiencies.

Our digital tokens are easily tradeable
 and follow the ERC20 standard. Enabling exchanges and applications to provide users with new trading opportunities and asset classes. 

Tokenized assets have taken
 off mostly as USD stablecoins but this is just the beginning.

We plan to launch
 tokens representing everything from oil and stocks to synthetic crypto.

Market Protocol can create digital tokens
 for any asset. With it, we have an opportunity to define a global market by delivering access and value to anyone in the world. 
Decentralized future contracts
Introducing 0xFutures, the first peer to peer platform to trade future contracts running on the blockchain. 

Meet Paul. Paul is a developer who gets paid in
 bitcoin. Paul loves his bitcoin but he hates to see the price go up and down especially when it goes down. He would love to have a way to stabilize his bitcoin holding and to keep the same value over time.

Meet Lucy. Lucy is a
 mega crypto enthusiast and really thinks that this thing is going to the moon. So she would like to put her crypto to work to take a leveraged position.

If the price
 moves, she will make even more money.

 0xFutures which is a fully decentralized trading platform where Paul and Lucy can create a smart contract that will track the price of any asset. Bitcoin, ethereum, gold or anything else really.

In their case it will be bitcoin.

With 0xFutures, every future contract is a
 smart contract running on the ethereum blockchain between the two participants. This means that the funds are not held by a 3rd party but by the smart contract itself.

This makes 0xFutures
 decentralized, peer to peer and trustless.

Here is how it works.

Let's say that
 Paul wants to create a contract that tracks the price of bitcoin. He can either be long if he thinks that the price is going up or be short if he thinks the price is going to go down.

 he wants to stabilize his bitcoin holdings, he will be on the short side. He then sets the contract amount, that's the money that is in play.

0xFutures uses the DAI as
 collateral. The DAI is a stable token that doesn't fluxuate over time. One DAI is worth $1.

Let's say he sets the contract
 amount to be 100 DAI which is the equivelent of $100.

So Paul creates a
 smart contract using 0xFutures that will be living on the ethereum blockchain.

Now Lucy
 wants to join this contract and take Paul's opposite position by going on the long side.

If the price of
 bitcoin goes up by let's say 30%, then Lucy who is long will be up by 30%. 

If in the contrary the price of bitcoin goes
 down by X%, then it's Paul who will see his share increase by the same amount.

At some point Paul may want to take his profit or loss
 and release his DAI's from the contract. He can do so by selling his side of the contract to another user who will replace him.

Once the contract has
 been rolled, Paul receives his funds held in the contract directly to his wallet.

 0xFutures, every trade is its own smart contract on the ethereum blockchain between two people.

There is no custodian,
 no centralized system and no counterparty risk.

Start today.
The Open Network for Transaction Requests
In this video I'll go over the basics of Request Network. The Request Network is a decentralized payment system which focuses on innovating in the areas of transaction cost, accounting, regulation and usability.

Request is an ERC20
 token based on the ethereum blockchain. In order to initiatie payments on Request, the potential recipient of funds requests an invoice from the payer and when the payer detects the request they can pay with one click. 

The recipient then receives their

Whenever a currency is sent on the Request network,
 a fee is charged. A small portion of the fee is also burned. The amount of currency burned is determined by the current supply and exchange rate.

The structure of the
 Request network consists of three layers. The core layer handles consensus of the states of transactions on the ledger. This takes place on the ethereum blockchain. 

The extension layer adds rules that can be added
 to requests, this can be implementing trade laws for a region or collecting taxes on transactions. 

The third layer is the application layer which takes place outside of the
 blockchain where 3rd party companies can access information by connecting to the Request network.

This can be used to access invoices to initiate
 payments, audit transaction history or any other type of accounting activity.

Some use
 cases for the Request network described in the whitepaper are realtime global accounting, automatic tax collection, international payments, machine to machine transactions and a cheaper alternative to payment systems such as Paypal. 

I hope you found this introduction

A traditional loan takes a lot of
 time and paperwork at the bank. Credit systems often neglect first time borrowers, young people and citizens of developing regions. 

Also the interest rates differ widely
 around the world, discriminating people in high interest countries.

Not anymore.

ETHLend connects lenders and borrowers all around the
 globe using blockchain technology. This creates a decentralized lending market where everyone can participate. Enabling competitive interest rates determined by the free market.

Katherine uses ETHLend
 and receives interest payments by lending money to people all around the globe including Sandeep in India who has a great credit profile.

Within a
 few minutes, Sandeep is able to receive a competitive loan. The loan agreement is legally binding and the funds transfer within seconds, securely handled through self executing contracts called Smart Contracts.

They even store
 loan collateral. Now Sandeep can improve his business.

 later repays the loan to Katherine who enjoys the safe profit she has made with the interest payment during her holiday on Mauritius.

Now Sandeep's
 business flourishes and he too because an ETH lender.
