Pickflix is by no means market ready and will need a lot of development and even more marketing. Just spending an hour or so messing around with the site I was able to come up with the following issues.

PickFlix is in BETA on the Rinkeby Test Network. For those of you who don’t know what Rinkeby is, it is A proof-of-authority blockchain, started by the Geth team or testing. The Ether can’t be mined; it has to be requested.

When I tried to run the game on the testnet it couldn’t even load my requested tokens and took ages to load the lobby

Terrible looking website

The website looks horrid, like something out of an Angelfire or Geocities site from the early 2000’s. It really offers users very little in terms of user experience and by no means an inspirational appeal. The call to actions are weak and there is no obvious user flow.

The site actually looks more like a maintenance page for a site that is yet to come than an actual working prototype on a testnet.

Clunky user experience

As with most ETH dApps you will need Metamask installed in your browser and while the sign-up process is easy it could do some work in terms of guiding the user on each step.

When you land on your dashboard you’re crudely thrown into a master account page with no guide on what to do next. You Kind of stumble around and figure things out and with so little incentive to do so, I hardly feel it was worth the effort and I’m sure many users will feel the same way.

Gaming explanations too complex

When reading through the documentation it was by no means clearly apparent on what I was meant to do or the value proposition on why I should do it. I think video explanations (since you are a movie based dApp) would be most welcome in explaining how the game works, why it’s fun, why you should get involved.

It was only when I signed up and went into the lobby that I really understood what was going on.

Also, there were not even test movies available for you to try out lol so you just have to hope and imagine what it’s like. This shouldn’t even be listed if you can’t even use the game even ina testnet phase

Pick Flix Lobby with no active movies

What I think of Pick Flix

As with every blockchain dApp I do think the concept has a lot of promise and could be fun if integrated with local movie theatre loyalty programs and movie review sites like IMDB and Rotten Tomatoes.

I think if the application thought a bit bigger to integrate user-generated content into the site and allow viewers to add their thoughts, reviews, ratings on the movie it would offer a richer experience for people and they would be more inclined to participate each week.

The game itself isn’t much of a game changer so they would need to rely on strategic partnerships in order to introduce the game to a wider audience and then to integrate it with users normal flow of finding information on upcoming movies.

If the can achieve this, the game might take off!

Disclaimers and such

This is a review for @dapplovers — Review a Featured DApp & Earn Rewards ft. State Of The DApps!. If you would like to try out a dApp and review it check out the instructions in the original post.

Have your say

Have you heard of PickFlix? Have you tried it out? What other dApplications do you use?

Holla at me in the comments! All my commenters I will now refer to as Jessie. Jessie is a good friend of mine, but Jessies got a girl, and I want to make her mine.

So have at it my Jessies! If you don’t have something to comment, simply comment “I am a Jessie.”

The Moonbeam Scaling Network: A “Semi-Decentralized” Scaling Solution

Moonbeam scaling solution

bitcoin exchange and hosted wallet provider Luno (formerly BitX) is developing a bitcoin scaling solution called Moonbeam. Unlike the lightning network, Moonbeam does not require SegWit’s transaction malleability fix and would be able to operate on the bitcoin network as it is today.

Moonbeam  aims to provide a way for multi-user bitcoin platforms — such as exchanges, hosted wallets, and payment processors — to easily open standardized one-way payment channels with each other, and thereby offload the bitcoin network from a growing number of transactions.

How Does it Work?

Moonbeam aims to take advantage of the fact that many bitcoin transactions occur among multi-user platforms. Using Moonbeam, these platforms can open standardized one-way payment channel contracts with one another to facilitate payments. By taking these transactions off-chain, Moonbeam can reduce transaction fees for those who use it and benefit bitcoin users generally by reducing congestion in the mempool.

These channels are simple smart contracts in which one party locks up a certain amount of bitcoins for a specified period of time (with the end point referred to as the “timeout”) for the purpose of sending payments to the other party. Before the timeout, the party that has locked up funds can send an unlimited number of off-chain transactions using those locked up bitcoins (until the channel runs out of bitcoins). Each channel involves only two on-chain transactions: one to open the channel and one to close it.

Because these intermediate transactions are off-chain, they are nearly instant. Without the need for a blockchain confirmation, the transactions only take as long as it takes to route an http request (think: loading a simple web page). These transactions would also be cheap. Only two transactions per channel require miner fees, and the rest are essentially free to the platform, though the platform could charge fees to its users.

The one-way payment channels used by Moonbeam are not a new invention. bitcoin inventor Satoshi Nakamoto embedded preliminary code for payment channels in the very first release of bitcoin, and more recent protocol upgrades like CheckLockTimeVerify have further enabled this usecase. bitcoin platforms could negotiate and implement these smart contracts on the blockchain today.

What Moonbeam aims to do is facilitate the creation of these channels between major payment platforms by using the Domain Name System (DNS) to route communications related to creating and using these channels. This way, high volume platforms can easily discover one another and enter into a payment channel smart contact using the standardized Moonbeam terms. Using the Moonbeam protocol, this process can happen automatically when it is more efficient to open a channel than sending payments on-chain.

Trust

The Moonbeam project overview indicates that it is “semi-decentralized.” It is labeled as such because while the Moonbeam network does not require platforms to trust one another, it does require users to trust their platforms. A hosted wallet with a Moonbeam address is a custodial account, where the platform is managing the funds, and credits and debits user accounts accordingly as users send and receive transactions. Exchanges such as Coinbase operate in this manner; users do not directly control their private keys. Moonbeam can be a useful tool for these services, but it will likely not be a suitable scaling solution for users who prefer to manage their own private keys.

Other Downsides

The Moonbeam specification document also mentions several other potential downsides. Among them is the cost of capital. In order to open these channels, sending platforms must commit capital in the form of bitcoin for a period of time. If the receiver does not use the channel, the sending platform must wait until timeout to regain control of the funds, entailing potentially large financing costs.

Another risk involves the use of DNS. DNS hijacking is an attack that involves rerouting domain name requests to an attacker’s server. These attacks could be used to receive payments over new channels that were meant for the authentic server.

While Moonbeam does not offer the level of decentralization of the lightning network, the fact that it does not require any fork to the network may may make it an attractive solution to bitcoin’s scaling troubles in the short term. It could be implemented by hosted wallet providers as soon as the project is production ready.

The current state of Moonbeam can be found on the project’s Github.
