Decentr ($DEC) - foundational cross-chain and cross-platform DeFi protocol

Decentr is a protocol designed to make blockchain/DLT mainstream by allowing DeFi applications built on various blockchains to “talk to each other”. Decentr is a 100% secure and decentralised Web 3.0 protocol where users can apply PDV (personal data value) to increase APR on $DEC that users loan out as part of of our DeFi dLoan features, as well as it being applied at PoS when paying for stuff online. Decentr is also building a BAT competitor browser and Chrome/Firefox extension that acts as a gateway to 100% decentralised Web 3.0
Allows DeFi Dapps to access all Decentr’s dFintech features, including dLoan, dPay. Key innovation is that the protocols is based on a user’s ability to leverage the value of their data as exchangeable “currency”.

A fee is charged for every transaction using dPay whereby an exchange takes place between money (fiat and digital) and data, and vice versa, either as part of DeFi features or via a dApp built on Decentr. They are launching pilot programmes in the following industries:
  1. Banking/PSP Industry: On Product launch, due to Decentr’s powerful PSP connections (including the worlds #2 PSP by volume), a medium-scale pilot program will be launched, which will seed the network with 150,000 PSP customers in primarily the Spanish/LAC markets, generating revenue from day one.
  2. “Bricks and Mortar” Supermarket/Grocery Industry: Decentr aims to ensure the long-term competitiveness of “bricks and mortar” supermarkets against online-only grocery retailers, such as Amazon, by a) building secure tech that allows supermarkets to digitise every aspect of their supply chains and operational functions, while b) allowing supermarkets to leverage this incredibly valuable data as a liquid asset class. Expected revenue by Year 5: $114Mn per year.
  3. Online Advertising Industry: Decentr’s 100% decentralised platform credits users secure data with payable value, in the form of PDV, for engaging with ads. The Brave browser was launched in 2012 and in 8 years has reached over 12 million monthly active users, accented by as many as 4.3 million daily active users.
Decentr recently complete their token sale on a purchase portal powered by Dolomite where they raised $974,000 in 10 minutes for a total sale hardcap of 1.25M. The $DEC token is actively trading on multiple exchanges including Uniswap and IDEX. Listed for free on IDEX, Hotbit, Hoo, Coinw, Tidex, BKex. Listed on CoinGecko and Coinmarketcap. Listed on Delta and Blockfolio apps.

How Do Ordinary Investors Obtain the Benefits of Polkadot and Its Ecological Projects?

How Do Ordinary Investors Obtain the Benefits of Polkadot and Its Ecological Projects?
As the most anticipated blockchain project this year, the advantages of Polkadot (The token ‘s abbreviation is DOT, hereinafter referred to as DOT) in terms of technology and ecology are no need to repeat again in that a large number of articles have conducted in-depth analysis of this.
This article will try to analyze from a new perspective whether DOT has the potential to become a new financing method for the industry, and on this premise, analyze its development and prospects.
At the same time, this article will also point out how we ordinary investors can obtain the benefits of Polkadot and its related ecological projects.
Whether Polkadot Can Become A New Financing Method to Determine the Project Ceiling?
At present, the blockchain project's own business cannot generate cash flow. The circulating market value and token price are completely affected by the inflow and outflow of funds, resulting in business such as lock-up, token burning, and DeFi to stimulate the needs of buying.
Therefore, whether a project can become a new financing method will determine the ceiling value of the project's market value and token price.
For example, the emergence of Ethereum in 2017 led to the rise of ICO, which gave birth to a unique blockchain format that development after financing. For the ICO project based on ERC20, because the early development is based on the Ethereum public chain, its financing is conducted in Ethereum.
CoinMarketCap data shows that the price of ETH was $8.13 on January 1, 2017, and the highest price for the year was $879.12. On December 31, 2017, ETH closed at $726.56, an annual increase of 89.37 times, and the highest increase was 108.13 times.
Similarly, the IEO rose in 2019 has made the token of an exchange a new financing method. The platform token represented by BNB all achieved good gains in that year.
Can Polkadot Become A New Financing Method?
Polkadot has the potential to become a new financing method,which mainly from three aspects:
  1. Slots Auction
  2. Web3.0 Foundation Project Incubation
  3. Substrate Parallel Chain Construction
About slot auctions. As we all know Polkadot is a cross-chain project, the main chain is called a relay chain, and the project access to the slots of the relay chain can achieve cross-chain, the structure is similar to an airport.
The relay chain is equivalent to the main building of the airport, and the slot is equivalent to the gate. The flight needs to be connected to the gate to realize passenger connection.
At present, there are four types of parallel chains managed by the Web3 Foundation:
  1. Ethereum-Polkadot, which is the cross-chain of Ethereum and Polkadot.
  2. Bitcoin-Polkadot, the cross-chain of Bitcoin andPolkadot.
  3. Edgeware, a smart contract project on Polkadot.
  4. Critical infrastructure projects, such as DEX or stablecoins.
If other projects want to connect to cross-chain of Polkadot, you need to use DOT to rent slots, and slot rental is time-limited and not unlimited. Therefore, if the project party wants to access the cross-chain of Polkadot, it needs to purchase DOT from the secondary market to lease the slot.
More importantly, the number of Polka Slots is limited. The initial plan increased from 5 to 50, and gradually increased to 200 thereafter.
Besides, the Web3 Foundation behind Polkadot commits large fund to incubate projects. As of now, the Web3 Foundation has incubates more than 100 projects, and all of these projects will have the opportunity to be connected to the Polkadot cross-chain.
On a offline meetup with Gavin Wood, founder of Polkadot about Substrate parallel chain construction, he said it is able to release a new blockchain based on Substrate in 15 minutes at an offline event.
This not only means that Polkadot is powerful, but also that Polkadot will attract many projects that do not focus on technology.
In fact, not all blockchain projects are good at or focus on technology research and development. Instead, most projects actually pay more attention to scene realization or capital operation.
The release of a new blockchain based on Polkadot Substrate can help these projects save a lot of time and personnel costs. Therefore it is naturally attractive to these projects.
Based on the three reasons above, Polkadot has the potential to become a new financing method.
How do ordinary investors obtain Polkadot's cross-chain conceptual income?
First of all, investors who have participated in Polkadot private sale can choose to pledge DOT on the official website https://polkadot.js.org/apps/#/accounts to obtain the POS yield as verification node.
In addition, you can also claim DOT mainnet assets on MXC for trading. On June 29, MXC announced support for Polkadot (DOT) asset mapping. Successful mapping is regarded as receiving Polkadot mainnet assets.
According to the official introduction, users can visit the MXC official website homepage, find "Assets" at the upper right corner, click "My Assets", select "Deposit", choose DOT (Polkadot) and click to get deposit address and copy.In a later stage, MXC POS Pool will also launch DOT's Staking products. Related announcement: https://mxc-exchange.zendesk.com/hc/en-001/articles/360045593011
MXC, Huobi and BTCMAX and other trading platforms have used their own foundations to participate in the private sale of the Polkadot (DOT). Therefore, the DOT/USDT trading pair on MXC is not exactly the IOU token.
Users who did not hold DOT in the early stage can consider holding it according to their own situation.
On the other hand, Poka is expected to open the transfer function in August when it will be officially launched on major exchanges. At present, KSM, EDG, PCX, AKRO and other Polkadot ecological projects have been launched on major exchanges, as shown in the figure below.
(Please note that the transfer function of the DOT is not enabled, and MXC supports DOT main network asset mapping. therefore, It is recommended to trade on MXC.)
It can be seen from the figure that the MXC currently listed most Polkadot ecological projects and is currently the main trading field of the Polkadot projects.
When there is related progress in the construction of the Polkadot network, its ecological projects tend to show a trend of linkage. For example, with the favorable news that MXC support users to claim DOT, PCX, one of the project in Polkadot ecosystem rose 5% in 24 hours and it still stay strong momentum.
In summary, how to continuously attract capital is the determinant of the market value and price of blockchain projects. The concept of a hot market at a certain stage often exists as a financing method, such as ETH,platform token, and so on.
While the slot auction, Web3.0 Foundation project incubation, and the construction based on Substrate parallel chain will help Polkadot to become the next financing method.
Ordinary investors can make arrangement on DOT and its ecological projects in advance, or pledge the DOT to obtain staking yield in ways that participate in the dividend of Polkadot development. As far as the listing projects are concerned, MXC is currently list most Polkadot projects among all exchanges, so it is expected to become the main trading field of Polkadot.

Enceladus Beta Starting Friday!

Enceladus Beta Starting Friday!
Hey Everyone! We haven't posted in a while, I've had my head to the ground building most of the winter. And now we're at a pretty exciting milestone, our first real beta test.
Enceladus is a retro text-based RPG with millions of items to craft or collect, thousands of enemies to fight, and many places to explore. It draws inspiration heavily from permadeath roguelikes and MUD style games, where you log on with a friend and pit yourself against mist wolves, ether mites, or skora raiders, but with a twist.
The biggest enemies are walking around with Ether, as in Ethereum, which is fully integrated into the game client. So taking down that legendary vampiric skullbinder shaman will earn your team actual crypto, that you can withdraw. It's a 100% free, with no ads or monetization. All donations go straight back into the game pool.
I've been working on this by myself for about a year now, some of you might remember my earliest updates in the weekly threads.
If that sounds at all interesting to you, reply to this post, and I'll pm you a beta key. There's currently about $200 of Ethereum in the game, and the server goes live Friday at 5pm MST, for two weeks. We'll see how it goes lol!
Please feel free to ask any questions about my process, vision, the game itself, whether it's all really an elaborate scheme to run bitcoin miners in your browser(no, it's not), or anything else that comes to mind. I'm really excited to see how many people we can get in the game at one time, and how well my server does.
\The server is written is nodeJS, and the client is using an early implementation of web components called polymer, the server is comprised of about 135,000 lines of code. It's not pretty :P**
Here are some screenshots!

Re-Launching The Borderless, Unkillable Crypto-Fiat Gateway, DAIHard. Enter or Exit Crypto via Any Fiat and Any Payment Method, Anywhere in the World, Without KYC. All you need is a little Dai.

Some of you might recall recall our initial facepalm failed launch about 3 months ago (post-mortem here). Well, we're back--this time with an audit and some new features. This version of DAIHard should should die a little harder this time ;)

The Audit

After shopping around a bit in the auditor space, we decided to go with Adam Dossa--the very same Adam Dossa that actually found our launch vulnerability and responsibly disclosed it to us! You can see his report here. By the way, Adam has been a gem: friendly, professional, timely, and flexible. Definitely keep him in mind if you need an audit!

(Re)Introducing DAIHard

Following is an updated version of our original launch post. If you've already read that, you might want to skip to the heading What's New in v0.9.2. Or you can go straight to the app or go to our info site for more info!
Here is a legitimate concern most of us are familiar with:
To enter or exit the crypto economy, we rely on centralized exchanges such as Coinbase, which track their users, impose limits, and are tightly coupled to their jurisdiction and its banking system. And for all we know, any day now regulations could start tightening these controls further (*we've actually seen some of this play out in the two months since our first launch post). In light of this, can we say in any meaningful sense that crypto is anonymous, limtiless, borderless, immune to regulation, and (most importantly) unstoppable?
To really address this concern, we need a completely decentralized gateway between fiat and crypto: something that extends the benefits of crypto to the very act of moving between the old and new economies. But the design of such a platform is far from obvious.
(Localethereum comes close, but as discussed under Unkillable, it doesn't quite cut it. And Bisq is decentralized, but has significant UX hurdles.)
We believe we've found a solution. We are proud to present:

DAIHard v0.9.2 - Almost Definitely Not Broken This Time

If you want to jump right in, we recommend first watching our latest usage demo (7 min), then diving in and giving it a shot with a small amount of Dai. (Try it on Kovan first if mainnet is too scary!)
DAIHard extends many of the promises of crypto (borderless, anonymous, limitless, unstoppable) into the exchange mechanism itself, allowing anyone, anywhere to bypass centralized exchanges and the control they impose.
More concretely, DAIHard is a platform, run on smart contracts, for forming one-off crypto/fiat exchanges with other users, in which:
Again, our latest usage demo (7 min) shows this process in action.

Two drawbacks

You Need either xDai, or both Dai and Ether, to Use The Tool (At Least For Now)

If you want to buy Dai on DAIHard, you must already have Dai--1/3 of the amount you want to purchase--to put up as a burnable deposit. For example, if you only have 10 Dai now, you can only commit to buying 30 Dai, and must complete that trade before using the newly bought Dai to open up a bigger offer (for up to 120 Dai that time).
Most tragically of course, this means that if you don't already have some crypto, you can't use this tool to get crypto--this is why we avoid calling DAIHard an onramp specifically. This comes from the fact that both parties must have "skin in the game" for the game theory to work, and a smart contract can only threaten to burn crypto.
We have some ideas on how to address this drawback in the not-too-distant future, which we'll write about soon. For now it's time to launch this thing and get some users!

Dangerous and Scary To Use

In rare cases, a user may have to burn Dai and face a loss on the entire trade amount. The necessity of this ever-present risk is explained in detail in DAIHard Game Theory.
However, a cautious, rational user can gather information (possibly via our [subreddit](daihard)!) about how people have used the tool, successfully and unsuccessfully. They can then create a buy or sell offer with wisely chosen settings based on what has worked for others. Other cautious, rational users can find this offer and commit to the trade if they dare. We expect the vast majority of committed trades should involve rational, cautious users, and should therefore resolve happily.
Still, inevitably there will be sloppy trades that result in burns. As the tool is used, we'll be keeping a close eye on the frequency of burns and keeping you guys updated (perhaps via a "System Status" utility similar to the one found on MakerDao's explorer). In the end, though, we expect the risk in using DAIHard to be comparable to the risk of using any exchange or DNM: ever-present but low enough for the platform to be useful as whole.
So, while DAIHard will never shut down and can't perform an exit scam, the bad news is it's not risk-free. Users will have to approach DAIhard with the same level of caution they would with any new exchange (albeit for different reasons and with a different approach).
So what's the good news?

The Good News

While these drawbacks are significant, they enable some remarkable features that no other crypto/fiat exchange mechanism can boast.


(Correction: Bisq seems to have a decentralized arbitration system)
We are aware of no other crypto/fiat exchange platform that is truly unkillable. Bisq and localethereum comes close, but both localethereum relies on centralized processes of arbitration. This means their fraud-and-scam-prevention system can be sued, jailed, or otherwise harrassed--and if that part stops working, it doesn't matter how decentralized the rest of the system was.
DAIHard, in contrast, gives the users the power to police and punish each other, via the aforementioned credible threat of burn. This is simple game theory, and the rules of this game are etched permanently into the DAIHard Factory and Trade contract code: impervious to litigation, regulation, and political pressure.
This Factory contract has no owner and no suicide or pause code. It cannot be stopped by us or anyone else.
Like Toastycoin, this thing was immortal the moment it was deployed (even more immortal than RadarRelay, for example, which does rely on an ownership role). Both DAIHard and Toastycoin (and probably whatever we build next) will last for as long as a single Ethereum node continues mining, and it will remain easy to use as long as someone can find the HTML/JS front-end and a web3 wallet.
(The HTML/JS front-end (built in Elm, by the way, with the lovely elm-ethereum!) is currently hosted on Github pages, which is centralized--but even if Github takes down the page and deletes the code, it's a minor step to get the page hosted on IPFS, something that is on our near-term roadmap in any case)

No KYC, No Limits

It's smart contracts all the way down, so DAIHard never asks any nosy questions--if you have Metamask or some other web3 wallet installed and set up, with some ETH and Dai (or just xDai), you can immediately open or commit to a trade. You don't even need a username!
(In fact, we're so inclusive, even machines are allowed--no CAPTCHA here!)
You're limited only by the collateral you put up, so if you have 10,000 Dai you could open up a buy offer for 30,000 Dai (or a sell offer for 10,000 Dai) right now.
We do reccommend trying the tool out first with a small amount of Dai... But we're not your mom! Do what you want!


It simply doesn't matter where you are, because DAIHard doesn't need to interface with any particular jurisdiction or payment system to work. DIAHard works by incentivizing people (or robots?) to navigate the particular real-world hurdles of bank transfers, cash drops, or other fiat transfer methods. These incentives work whether you're in America, Zimbabwe, or the Atlantic; they work whether the fiat is USD, EUR, ZAR, seashells, or Rai Stones; and they work whether your counterparty is a human, an organization, a script, or a particularly intelligent dog with Internet access.

Any Fiat Type, and Highly Customizeable

Here are some examples of the types of trades you might create or find on DAIHard.
As the DAIHard community grows, users will doubtless find much more creative ways to use the system, and we will discover together which types of trades are reliable and which are more risky. Because users can set their own prices and phase timeout settings, we expect the risky trades to charge a premium or have longer time windows, while the reliable ones rapidly multiply at close to a 1:1 price ratio, with quick turnaround times.

Extensible (with profit) by Third Parties

Not satisfied with our interface? Do you have some nifty idea for how to display and organize user reputation? Or maybe some idea for how trades could be chained togeher? Maybe you'd like to design a notification system for DAIHard? Maybe you just want a different color scheme!
Well, you won't need our permission to do any of this. Any tool that watches the same Factory contract will share the pool of trades, regardless of which tool actually creates the trade. This means we don't even have to fight over network effects!
And if you look closely at our fee structure, you might notice that only half of the 1% DAIHard fee is "hardcoded" into the Factory contract. The other half is set and charged by our interface. What does this mean for you? If you go out and make a better interface, you can essentially replace half of our 1% fee with your own fee--it's up to you whether it's smaller or larger than the replaced 0.5%.
The reason for this is to explicitly welcome other developers to extend what we've built. For as long as our team is the only one improving the platform, a threat to us is a threat to future upgrades. But if others begin extending the DAIHard platform too, then DAIHard will not only be unstoppable as it is today, but also grow unstoppably.

(For Real This Time) This Is a Big Fucking Deal

DAIHard is a turning point in crypto and a breakthrough in decentralized markets, and is an irreversible augmentation of the Ethereum platform.
What we've built is a gateway to crypto completely devoid of centralized components--rendering entry and exit to crypto unkillable, flexible, borderless, and private. Centralized exchanges, and the control they impose, can now be bypassed by anyone with Dai and a web3 wallet.

What's New in v0.9.2

There have been many changes made since our first failed launch, but there are two rather important ones: xDai support and reputation tools.

xDai support

DAIHard is now operational on xDai, a sidechain whose native token (xDai) is pegged to the Dai (and therefore $1). Add the xDai network to your Metamask (or just install Nifty Wallet), then switch to the xDai network in your wallet, to try it out. xDai has some pretty incredible benefits, compared to vanilla Ethereum:

Reputation tools

We now have a few reputation tools. First, on any open trade, there is a widget showing the number of releases, aborts, and burns the given address has been involved in as that role (buyer or seller). Clicking on this expands the widget to show more detailed information, and also provides a link to a page that lists each trade this user has been or is involved in.

What's next?

We have tons of ideas on how to improve the product--too many, in fact, to commit to any before we get a good chunk of user feedback. Here are some of our favorite ideas:

Near-Term, Smaller Features

  1. Lots of usability improvements.
  2. A "System Status" utility similar to the one found on MakerDao's explorer).
  3. Marketplace / My Trades rework.
  4. A "QuickTrade" page, offering Trade Templates as an alternative to the current Create Offer page.

Big Exciting Features

  1. Bootstrapping people with no DAI via other mechanisms and community outreach.
  2. Partial commits to trades. eg. Place a 10,000 DAI trade and allow it to be picked up in blocks larger than 500 DAI at a time.
  3. More chains, get this thing working on Bitcoin via Rootstock, on Ethereum Classic and Binance Chain.

Stay Informed!

A lot of the above features will be prioritized more clearly as we get user feedback, and we will be posting fairly frequent updates and articles on our info site. If you don't want to miss anything, note the subscribe widget and sign up!
