Rating wallets for TRON DApps by TronHives.com
By: Anthony Lapid
Tags: Tron, Smart Contracts, Trx, Dapps, Blockchain

When we created the game BeeHive, we were faced with the task of advising our players from which wallets supporting TRON would be most convenient to participate. Having gone through the Internet and not finding a single such rating, we had an idea to create our own.

I want to bring to your attention my rating of wallets that support Dapp on the TRON blockchain.

I divided the article into two blocks: participation from 💻PC and 📱smartphone.

______________

Very important: Before using any of the wallets — make a backup, because if you accidentally log out of the wallet, then it will be impossible to recover funds!

______________

It turned out that for participation from a 💻PC there are not so many options. Optimal use of browser extensions for Google Chrome.

1. TronLink — the best way to participate, in our opinion. The wallet supports the main and test networks, is systematically updated and has everything for comfortable participation in DApp applications.

Download: Google Chrome

2. TronPay is the second most popular browser extension, in many respects inferior to its competitor, both in the number of users and in the activity of developers.

Download: Google Chrome

3. MathWallet is the third application on our list. The newest, but actively developing. Of the main advantages:

The browser version is Google Chrome and Opera. However, be careful when participating, because the applications are quite new and there are no guarantees that they are not subject to risks of hacking or bugs.

There is a test network Tron Shasta, however, using it to test new applications will not work because the resource uses its DApp Store, which hosts applications from the main network.

Download: Google Chrome, Opera .

More options for using the PC to participate in the Dapp, unfortunately, I could not find.
Smart Narrative White Paper

We’ve published the first version of the Smart Narrative™ white paper. It’s a first cut at a moving target, given the ongoing developments in blockchain enterprise initiatives, smart financial contracts and security tokens. As we build out the demo app running on mock events to a full-blown prototype ingesting live event streams, the white paper will evolve as well.

The decentralized strategy framework (DSF) that forms the foundation for smart narratives emphasizes the role of governance. In a section titled “The Parable of Kodak,” we illustrate the importance of consensus across the three layers of the narrative stack — enterprise, technology and personal — in crafting effective strategy. Kodak might have had a more effective enterprise narrative if management had been more in sync with the engineering group that essentially invented the digital camera.

Present-day scenarios playing out at large tech companies like Google and Microsoft offer more examples of the importance of listening to employees. From resisting military contracts to gender inequality, the personal narrative has greatly influenced its enterprise and technology counterparts.

Moreover, the network model that Smart Narrative Inc. will follow in launching its first member, Smart Green Capital, depicts how the combined efforts of all three enterprise types — profit-oriented, NGO and nation-state — may be the key to solving our undeniable climate crisis.

As governments grapple with the issue of how to regulate cryptocurrencies, the importance of blockchain enterprise applications continues to grow exponentially. We are at an inflection point of innovation and opportunity, with the chance to meaningfully impact society.

Can smart contracts end the fraud tradition of recent Turkish history?
By: Burak Akın
Tags: Çiftlik Bank, Security, Blockchain, Fraud, Smart Contract

You can always find news in Turkey about fraud. The method, the channel or the size may differ from case to case but the concept has been continuing for decades. The history of this tradition has three outstanding examples. First one is Osman Ziya Sülün (1923–1984). He is a pioneer of swindle in the region and a shining example of this tradition. His strategy was simple: offer goods that he does not own to his target, collect money then vanish.

Galata Tower which is located in Istanbul and built by Genoese is one of the properties sold by Sülün Osman. It has been using as a museum since the late 1960s. Photo by Selim Çetin

The second example is Fadıl Akgündüz who is the founder of Jetpa Holding. He is called “Jet Fadıl” after his company. He had been active in several areas including tourism, football, real estate and politics. During this time, there are several examples of his “unsatisfied premises” however, the last one is the most highlighting one. He pledged an island in Maldives exclusive for Muslims and started a marketing campaign in 2014. He collected approximately 170 million USD from 60 thousand people. Unfortunately, the people neither could take back their money nor enjoyed the island since there was no existed investment in the Maldives.

“Fadıl victims” who could not get their real estate which they already paid for, is going to the court to follow the case against Mr. Akgündüz.

The third and most recent example is Çiftlik Bank (Farm Bank). The founder of the platform, Mehmet Aydın provides an online farming game to the users. In this game, users would buy farm stuff with real money, Mr. Aydın was supposed to use this money for real farming investments and delivering back to the users. Eventually, he fled away from Turkey with millions of Turkish Lira collected from the players in 2018, therefore, users could not get back their money.

In brief, although all of these three examples are at different times or using different sectors, they have three characteristics in common.

The promisor does not build his premise on facts.

For instance, Sülün Osman was not the owner of the Galata Tower, at all. Britannica defines fraud as “the deliberate misrepresentation of fact for the purpose of depriving someone of a valuable possession.”. This case has full compliance with this description. The contract was not transparent all the time, sometimes it is not even formal.

So, the victim could not prove that he has paid for the Galata Tower since this agreement cannot be proven from another subject. The contract, formally or verbally, is centralized.

It means that if something happens to the center, the contract is gone. For instance, if Fadıl Akgündüz or Mehmet Aydın suddenly shuts down the operations, the users would not have control over it and lose all of their investments. And that is the exact case already happened.

Here is the point that we dive into the smart contracts.
“CEA” Fair launched
By: Aqua Finance
Tags: Binance, Defi, Smart Contracts, Token, Farm

Hope everyone is having a great weekend so far. For Aqua Finance it have been a hectic and hard working week because just yesterday (23rd July,2021) we launched our new token $CEA out to The ocean as well as our Ocean world.

$CEA was free launched and we tried our best to protect the community from bot, even if it is not 100% but we did get a lot of positive comments from our community that we did quite a good job for that.

$CEA is quite different from $AFI, when you compare it.

First, $CEA will mainly be used to power up and get more skin for our Game. Therefore, The more you have $CEA The easier it gets with games and chances for Gacha to win prizes.

Second, you earn $CEA from farming which is something we also launched out on 23rd of July, 2021.

Announcing the “L14” test-network
By: Fabian Vogelsteller
Tags: Launch, Fashiontech, Smart Contracts, Testnet, Lukso

Welcome the LUKSO test-network, dubbed “L14” after the infamous “Sun King” Louis XIV ⚜️, king of France and the person who made high fashion in Europe a thing. With the help of his finance minister Jean-Baptiste Colbert he made france one of the strongest leaders in this new economy. Colbert introduced fashion seasons, and Louis XIV was with 72 years also the longest recorded reign of any king in Europe.

Louis XIV, king of France from May 14th, 1643 to his death in 1715

We dubbed the test network “L14” as it is a pure Proof of Authority (PoA) network with currently 4 block producing validator nodes, and is therefor a semi-absolutistic network, as was the reign of fashion king Louis XIV.

L14 functions as the first test-network, to allow the LUKSO community to build and test on a common infrastructure. Later test-networks are planned to have the HBBFT, which we are developing together with POA.network, combined with a PoSDAO governance to explore and improve on the first LUKSO mainnet consensus algorithm.

Getting started

To use the test-network you can simply connect your dapp, or wallet extension to https://rpc.l14.lukso.network.

You can check your transactions on the network, in the L14 instance of Blockscout.

If you simply want to play around with smart contracts, you can use a wallet extension like Nifty or Meta-Mask, connect to https://rpc.l14.lukso.network and use Remix to develop and deploy smart contracts.

Faucet

To get started you need some testnet “LYX” to pay for the transactions. You can get some using the L14 faucet.

Remix

In Remix simply log into your wallet extension and connect Remix to the L14 testnet. You can do this by connecting your wallet extension to your own, or our custom RPC endpoint. In Remix simply choose then from the tab ”Run” > “Environment” and select ”Injected Web3".

This will allow you to program and deploy smart contracts, using the Remix interface on the L14 testnet.

➡️ You can find more information and links to tutorials in our wiki guide.

Running your own node

If you decide to run your own node, make sure you use the correct spec.json and use at least parity version 2.2.7. If you start your node with the following parameters, you are connected to the L14 testnet:

$ parity --chain spec.json --bootnodes enode://6a6b0b286e3f96dee993d995f3fd435a065388664e211f02533e28c9ddc31089eb90f71d1386c3c74ee60f79df86cacdb10992c38e2f9cccac4881cb84526415@35.195.116.26:30303

Flipside Daily Mover: ENG

ENG Launches Testnet Focused on Developers

June 18, 2019

ENG Developer Behavior climbed 3.53% over the last 30-days. FCAS is up 46-points (7.26%) as User Activity also spiked 77-points (18.97%). Market Maturity is down 7-points (-1.15%). Price is up 21.66% over the same time period.

Ready to Deploy

The Daily Mover spotlight was on Enigma back in early April as the team was gearing up for their next major milestone, Testnet release. At the time, fundamentals were on the rise while the team released their open-source code, provided details around Discovery mainnet tokenomics, and revealed specs on how to run one of their secret nodes. There has been considerable excitement around ENG’s decentralized platform, as it is equipped with secret smart contracts that can call any function on an Ethereum smart contract while maintaining end-to-end privacy.

On June 11th, ENG finally unleashed their Testnet Developer Release of the Discovery Network, a major step towards mainnet launch on Ethereum. Fundamentals were on the rise leading up to launch and have maintained a significant upward trend in the days following. This release is geared towards developers looking to build features of their DApps on top of Enigma’s encrypted infrastructure. Once built on testnet, Developers will be able to directly deploy their code in the public version of the network, so that Discovery can launch with live applications.

🌶️ Hot Take

A common theme in Daily Movers as of late (evidenced by yesterday’s coverage of the Credits platform) has been around what competitive differentiators blockchain platforms can offer to the market in order to attract DApps and enterprises to utilize their ecosystem. Many have relied on transaction speeds and scalability as main drivers of adoption, but none have been able to deliver what Enigma is bringing to the market.

By leveraging secret smart contracts to perform off-chain computations on encrypted data and using Ethereum as a consensus layer, the team is delivering privacy and scalability to the market in a way no other projects can match. While a mainnet launch date has not been set, Engima has carved a niche for itself in the space and will be an exciting project to watch through 2019.
NEL First Bi-weekly Report of June
By: Robbie Wang
Tags: Blockchain, Smart Contracts, Wallet, Dex

This report tells the NEL latest development in the first half of June

Neo-cli-nel

Followed up to V2.10.2 and the online version was upgraded to 2.10.2

NNSDEX

NNSDEX will be logged in using the Teemo wallet. The functions and testing of the NNSDEX trading section have been completed. It supports the use of CGAS and NNC for domain name auctions and purchases.

Added a new use case to NNC. Users need to stake NNC for an open order of pre-owned .neo domain names, and NNC will be returned after the pending order is canceled or closed.

We also added the email notification function to NNSDEX. You will be notified by email when someone buys or purchases your domain name.

We plan to integrate domain name binding, mapping, renewal, and auction functions all into the NNSDEX.

Due to transaction fee restrictions in the NEO, NNSDEX is temporarily unavailable. NNSDEX will go live after NEO changes its transaction charging strategy, which is expected to be in the second half of this year.

Trading market_buy

Trading market_order details

Account_my domain list

Account_Set email notification

Developed the query function for dex domain name holding information

Developed the query function for dex available domain name list

Developed dex open / bind / modify email functions

Developed the dex delete email notification function

Developed the dex email verification function

Developed the dex email status query function

Developed the dex automatically send verification information function

Developed the dex automatically send notification data function

Made .test and .neo domain name queries compatible with each other

Teemo Wallet

Fixed a bug where the transaction size that is large than 1024 bytes causes the transaction to be unrecognized. For transactions that are larger than 1024 bytes after packaging, the transaction is reconstructed and the transaction fee is automatically added to ensure that the transaction can be sent.

Followed up with node upgrade, upgraded the corresponding interface of Teemo wallet.

NELSwap

We developed the token decentralized exchange NELswap based on the constant product protocol, and users will be able to make market and exchange tokens on NELswap. NNC will provide liquidity for a variety of tokens.

The contract for NELswap has been completed.

The static page of the web-side trading and exchange page and the funds pool management page has been completed, and the function will be completed next week.

Real-time access to USD/CNY exchange rate data and GAS/USD exchange prices allow it possible to determine token prices at NELswap.

The development of the NELswap market price analysis page will continue.

Like NNSDEX, NELswap is temporarily unavailable due to transaction fee restrictions. It will go live after the NEO fee strategy has been revised.

Others

The background monitoring adds monitoring of the api interface service to ensure the stability of each application interface.
Zilliqa Enters Year 3!
Tags: Cryptocurrency, Bitcoin, Zilliqa, Smart Contracts, Blockchain

We all know the team to be academic professionals who build, not for ego, but for purpose. And that hype and fuss are nothing but distractions during construction. But now, the project is alive! June 18 is the day we begin to really get hype!

A live stream was broadcast (click here), as the team relayed to us in further detail, what some of the various projects and collaborations have unearthed.

Updates on Project Proton and Unstoppable Domains showed that the pipeline is loaded and moving forward. There were also new announcements; like blockchain and the future of payments in South East Asia coming through a pretty major collaboration with Xfers.

Another dynamic on the horizon, is called Zil-Hive, which will see Zilliqa and LongHash team up to support and train blockchain startups building on Zil. Very exciting stuff!

And there is still much more in store as well, but regardless of what has yet to come, what has already arrived is quite the marvel! The future really is now.

Builders build to build. Not for clout. But those who build great new things, inevitably receive praise, or clout; a word that means influence or power; dominance.

I have no doubt that the Zilliqa network will influence the blockchain space, and eventually, establish a dominant presence in the area of smart contracts. Scilla is ahead of its time, and as developers come to understand its brilliance and security, that’s when its power will shine forth. It’s the dawn of a new era. What will you build?

What they’ve done is create a new land mass in the digital sphere. New ideas, and communities, and companies will be bred from, and live on this continent of consensus. Zilliqan Zeal will fertilize the soil, as diligence and determination water the seeds of innovation. And we as a community, can all come together to reap the harvest.

So Happy Birthday Zilliqa! Job well done. Here’s to Year 3!

Speculative design of a self contained microfinance scheme

Speculative design of a self contained microfinance scheme

This article is about enhancing a peer to peer microfinance scheme by factoring in the risk of default among peers.

Chit fund

A chit fund is a rotating savings and credit scheme practiced in India.

Chit fund model

A group of people contribute a fixed sum monthly for a period of time followed by an auction with a winner every month.

chit fund

Assume 5 people participate and contribute 100 for 5 months. On the first month the contribution to the pot is 500.

On the first month assuming 2 of them participate in auction the first person offers 20 to win the auction the second offers 40.

The second person is declared the winner and given the lump sum of 500–40. The 40 is paid to the other 4 subscribers, i.e. 10 each.

So 4 of them have contributed 100 (in the first month) and received 10 as interest/dividend.

The process continues monthly with the winner of each month being taken off the list of auction participants.

So each subscriber can win once in the auction and each subscriber has to contribute the monthly amount until the end of the process.

Associated Risks

Winner default — Stops contributing after winning Subscriber default — Stops contributing Organizer fraud — The organizer absconds with the amount

Existing stats

Subscriber default — 35%

Winner default = 24%

Chit fund model with risk factored in

Ingredients

Peer group Smart contract Risk model factored in

Peer group

Peers participating in the scheme need one or 2 guarantors who are also participating in the scheme taking care of subscriber default (to a degree).

Smart contract

A distributed smart contract will take care of the organizer risk (to a degree without hacks etc).

Risk model factored in

Based on existing stats, front load the risk

Subscriber default — 35%

Winner default = 24%

Marketing/Operating cost — 10%

2. Add guarantors

3. Fail fast

Front loading risk

Assume a total cost of 60% (risk + operating cost), factor it into the monthly payments. So the monthly auction starts only after the 60% is front loaded.

So 5 monthly payments would become 5+3 = 8 monthly payments.

chit fund risk

Subscribers contribute for 3 months filling up the pot before the auctioning starts.

Add Guarantors

While creating a peer group for the chit fund add one or 2 guarantors. If one of the participants stop paying in, the guarantors who are also subscribers would step in and contribute the monthly amount.

Fail fast

If the whole scheme goes in the red (i.e winner defaults) wind it up and return the amounts proportionately.

The above is a speculative design of a self contained peer group microfinance managed by a smart contract.
ASI The Very First DeFi project to implement Artificial intelligence and Machine Learning
By: Artificial Super Intelligence
Tags: AI, Erc20, Uniswap, Defi, Smart Contracts

ASI Ecosystem

By joining the ASI Ecosystem you will earn rewards that will automatically increase in your wallet based on your ASI score and your ASI token amount, your score will increase if you’re holding or topping up your wallet.

ASI score:

Buy ASI from uniswap and ASI will automatically give you an initial score of 1 or more, depending on the amount bought. The score is multiplied by the amount bought to give your holding share for ASI rewards distribution. There are 3 ways to adjust the ASI score:

Buy And Hold (BAH):

0.1–499 ASI Traders which means no score to be stamped in the ecosystem’s smart contracts the transaction fees will be 1.2%

500–4999 ASI > score 1> Trading fees 1.1% 5000–24999 ASI > score 1.1 > Trading fees 1% 25,000 to 49999 ASI > score 1.2 > Trading fees 0.9% 50,000 to 99,999 ASI > score 1.3 > Trading fees 0.75% More than 100,000 ASI > score 1.4 > Trading fees 0.5%

ASI score adjustments:

The smart contracts will adjust each holder’s score to distribute the new rewards amongst them based on the mechanism below.
Two Channel Hyperledger Fabric Network using Fabric-CA
By: Arjun Raghurama
Tags: Smart Contracts, Hyperledger, Blockchain

Overview

This article describes how to setup two channel Hyperledger Fabric network using Certificate Authority. The network contains two channels. Channel-1 includes ORG-1, ORG-2 and ORG-3 PEER. Channel-2 includes only ORG-2 and ORG-3 PEER.

Once deployed, the system will look like this:

Overview of deployed Fabric network

Setup

Let us create a directory to clone the git repo.

mkdir multi-channel

cd multi-channel

Let us create a folder for the Hyperledger Fabric binaries and download platform specific executables and set the environment variables to point to bin directory.



cd hyperledger-fabric

curl -sSL mkdir hyperledger-fabriccd hyperledger-fabriccurl -sSL https://bit.ly/2ysbOFE | bash -s -- -d -s

Downloading Hyperledger fabric binaries

export PATH=$PATH:$PWD/bin

peer version

Setting up the environment variables

If ‘peer version’ command executes successfully that means the binaries are downloaded and the environment variables are set properly.

Now clone the git repo two-channel-fabric-network



git clone cd ..git clone https://github.com/arjunraghurama/two-channel-fabric-network.git

Scripts in this repo are modified versions from Hyperledger test network repo. Now run the below commands to start the network. “start.sh” will call multiple scripts to create and register users and will bring up the ORG PEERS.

Once the peers are up they will join the respective channels.

channel-1 : ORG1 PEER , ORG2 PEER and ORG3 PEER

channel-2 : ORG2 PEER and ORG3 PEER

cd two-channel-fabric-network

./start.sh

Starting the network

The smart contract (chain-code) that will be used in this example is Fabcar. Which is present in “smart-contract” folder. To deploy the smart contract run the below command. We are not initializing the ledger in this example. Hence the leger will be empty in both the channels.

./deploySmartContract.sh

Deploy Smart contract on the network

Now let us create few cars in channel-1. For this we will use “queries.sh”. On line 21 set CHANNEL_NAME=“channel-1”. More importantly uncomment line 37 to invoke functions on channel-1

Changes for channel-1 in queries.sh file

When you execute “queries.sh” with above changes, CAR1 is created in channel-1

./queries.sh

Running queries on channel-1

To create cars in channel-2 do the following changes. Set CHANNEL_NAME to “channel-2” and uncomment line 40 and comment out line 37 as shown below

Changes for channel-2 in queries.sh file

Other functions such as queryCar, queryAllCars and changeOwner can be found in queries.sh file

Once everything is done run the “stop.sh” script to cleanup everything. This will clear all containers, certificates and other generated files.
I’d be wary of promoting anything that uses Proof-of-Stake or Delegated-Proof-of-Stake.
Tags: Proof Of Stake, Cryptocurrency, Eos, Smart Contracts, Ethereum

I’d be wary of promoting anything that uses Proof-of-Stake or Delegated-Proof-of-Stake. There is no free lunch, and though PoS has the siren call of transaction throughput, there are tradeoffs for network security.

Steem is going through this right now, as Justin from TRON token fame has just executed a hostile takeover of their network. How? By taking all the centralized tokens and “powering up” essentially using them as votes to push through what he wants.

Any blockchain that uses PoS and its variants are susceptible to this kind of attack. Its one of the reasons that Ethereum has been stalling their “upgrade”, as Vitalik slowly realizes that he needs more and more security apparatus (“Oracles”, “Shards” and the like) to boost security.

However, its a losing battle.

The fundamental premise of PoS is that your coins are your vote, your influence. This mirrors the real world where the largest wallet often wins, in business and in banking.

EOS falls under this category too, and frankly most competing coins for smart contracts fail with their initial premise — “Turing Complete” means every node must know about the state of your code, which inherently doesn’t scale, at all.

With Ethereum kicking the can and delaying the “Difficulty Bomb” that would force them to upgrade (second time, now for another 12 months), I don’t see an easy resolution to their PoS hybrid experiment.

In fact, I think ETH is dead-coin-walking, they just don’t know it yet.

Waves-dApp.com provides an auto-generated UI from dApp meta information and works via Waves Keeper and/or other Web3 providers inside the Waves ecosystem.

It works with mainnet, testnet, stagenet, and even customnet(localhost:6869). Just paste a dApp address in the searchfield or url, and the app will figure out the network from the bytes of the address and operate with the correct node. If you forget to switch Waves Keeper’s network, the website recognizes this and prompts you with a warning.

When the user invokes a function, Waves Keeper pops up and requests confirmation.

Who is this for?

Plug in Google Chromecast to your HD or Smart TV (as most people have these). The device will get power from the TV through the HDMI port where you attach the device. If that doesn’t happen, then you can use a power adapter in order to start the device.

The next step is to go to www.cast.google.com/chromecast/setup in order to download the Chromecast app. Once you have downloaded it, then you need to install and launch it.

After that, click continue and move ahead with the step process.

You need to select the right Wi-Fi network in order to use your Chromecast. Enter the password and give a name to the network.

That concludes the Google Chromecast setup, and you are ready to cast.

In case, you come across any issue, you have the privilege to get the best Chromecast help. There are many companies that offer a comprehensive support for Google Chromecast. You can just call 866–217–4179 at one of the Chromecast support and get the right assistance regarding your issue.
Why Video Casting Will Make Your Video Streaming App Much Better!

Nowadays more and more households shift from cable TV to external streaming platforms like Netflix, Hulu, Amazon Prime, etc. Cable-vision, that once, was the main source of entertainment to watch the news or the latest movies, now has become a sort of irrelevant. Not to talk about the interactivity between the user on the couch and TV - that was unheard of back then.

Just a simple, yet genius concept like video casting from your smartphone to any regular TV with an HDMI port, gives the user an immersive experience. But there is a catch… You need a separate device such as a Google Chromecast, Apple TV, or Roku. On the other hand, no sketchy contracts to sign, no installation fees, just a couple of bucks, and you have such a device that will be irreplaceable afterward (trust me).

Let’s cut to the chase, currently, we are still in a chaotic period where people don’t want to risk their or their family’s health, so the consumption of shows, movies have risen densely. This gives us, the developers, motivation just to make our streaming application much better and offer the best user experience to the customer.

There is a lot of information, tutorials on how to implement casting to your OTT (Over-the-top) application. A bunch of technologies offers this function, however, there is one development framework in particular that I’ve been keen on using it for my next OTT app.

ReNative - simply put it… it’s React-Native on steroids. And with one codebase I can develop the OTT app with video casting capabilities in less time and cover a lot more mobile/tablet devices. You should check this framework here! And give me feedback on how implementing casting capabilities to the app benefit in the awareness of your app in today’s OTT market!

How to: Install Xbox Game Pass on Chromecast with Google TV

A great option for playing Xbox games while traveling, or just while in another room at home. Patrick Aug 25·2 min read

The latest iteration of Chromecast, the Chromecast with Google TV, is powered by Android. Microsoft already offers Xbox Game Pass as an app for cloud gaming on Android devices, however this app is not yet available on the Play Store for Google TV devices.

With a few tweaks, you can get around these restrictions and install Xbox Game Pass on your Chromecast with Google TV. With this option you can stream stream Xbox Series X|S games to your TV — no console required.

Steps

Install the Downloader app Enable Unknown Sources Install the Xbox Game Pass app Connect a controller Play

Install the Downloader app

First, you’ll need to get the Xbox Game Pass app onto your Chromecast with Google TV. Because it is not available on the App list on your Chromecast, you’ll need to install it manually. The Downloader app will help you do this.

On your Chromecast, go to the Apps screen Search for and install “Downloader”

Enable Unknown Sources

Because you’ll be installing from a source other than the official Google Play store, you need to tell your Chromecast to allow installations from other sources.

On your Chromecast, go to Settings > System > About Highlight the “Android TV OS build” menu item, and click the OK button on your Chromecast remote 5 times in a row. You should receive a message that says you are now a Developer. Go to Settings > Apps > Security & Restrictions Enable “Install unknown apps” for the Downloader app

Install the Xbox Game Pass app

You’ll need to get a copy of the Xbox Game Pass app by downloading and installing it to your Chromecast with the Downloader app. APK Mirror is a useful resource that hosts apps available for download outside of the official app stores.

From the home screen, open the Downloader app Within the Downloader app, search for Xbox Game Pass (beta) APK Mirror, or go directly to this URL: https://www.apkmirror.com/apk/microsoft-corporation/xbox-game-pass-beta/ Download the latest version of the app with the armeabi-v7a architecture. Here is the one I used.

Connect a controller

A bluetooth controller is required to play Xbox games on the Chromecast with Google TV.

On your Chromecast, go to Settings > Remotes & Accessories > Pair remote or accessory Enable pairing mode on your bluetooth controller. Any bluetooth controllers should work. The Xbox controllers work well. Initiate the pairing on Chromecast when your controller is discovered.

Play

With the Xbox Game Pass app installed and your controller connected, you have everything you need to get gaming.

From the Chromecast home screen, open Game Pass Beta and login to your Microsoft account. Play!

Questions

How well does it work?

Pretty well. The game menu system is a little bit clunky (it’s optimized for touch interfaces), though game streaming is just as smooth as on any other Android device.
Meross Outdoor Smart Plug review: A capable, if basic outdoor plug
Tags: Home Tech, Entertainment, Electronics, Chromecast

Chinese brand Meross is pushing into the U.S. with a wide range of Wi-Fi smart home gear, including this outdoor plug with a familiar design.



The all-black device offers two three-prong sockets (each with a flip-out cover) and is certified as IP44 weatherproof (which is basically just protection against splashes and large solids. You can read more about IP codes in this story.) Devices that draw 10 amps or less are specified for use, and the unit supports only 2.4GHz Wi-Fi networks.



This review is part of TechHive’s coverage of the best smart plugs, where you’ll find reviews of competing products, plus a buyer’s guide to the features you should consider when shopping for this type of product. Christopher Null / IDG The two sockets can be powered on independently, but only within the app or via HomeKit.



The Meross plug is widely compatible, including support for HomeKit, Alexa, Google Assistant, SmartThings, and IFTTT. I initially set the unit up in iOS with HomeKit, and it was connected to my network in a matter of seconds. Later, I fired up the Meross mobile app to test managing the device via the official interface, and while it wasn’t immediately intuitive how to add a device to the app which had already been registered with HomeKit, after a little trial and error the plug appeared within the app.



As you might expect, there’s not much to it. One helpful feature is that, within the app or within HomeKit, you can control the two sockets individually, so one can be on and the other off, and so on. There’s only one physical power button on the hardware, however; it controls both outlets simultaneously (turning both on or both off) regardless of how you have them set in the app.



Aside from manual on/off control, the usual smart home features can be found in the app, including a section that lets you configure preset scenes, a scheduling system (including sunrise and sunset options), and an auto-off timer. The app also allows you to disable the green LED on the top of the plug should you prefer an LED-less solution.



[ Further reading: The best smart switches and dimmers ]While this plug is fairly basic in operation, I found it worked well throughout the bulk of my testing. It was normally responsive to commands in less than a second, only occasionally becoming unresponsive (usually when I was trying to turn the LED on or off). The $20 price tag is right in line with most other plugs with a similar feature set, and while the questionably translated website and manual may generate some small crisis of confidence, the required financial outlay should be small enough to minimize those concerns.
