Standardizing how DApps talk to Ethereum and avoiding the IE7 hell In order for a DApp to function properly, it needs to communicate with the Ethereum network.That is often done by initializing Web3 (from AVSA's post): Problem is, this only works on browsers which support Web3, which isn't the only way to communicate with an Ethereum node.Parity, for example, does things very differently with its own library, parity.js.Even Web3 itself will be updated soon, rendering the old initialization obsolte.That creates a scenario where either a DApp is locked to a specific platform, or the code must have a very complex initialization logic.This reminds the old, dreaded times of writing vendor-specific code to handle, for example, IE7.Hopefully, we can avoid that nightmare.Obviously, we can't expect programmers to agree on any particular high-level library.The only possible solution is, thus, a simple, low-level, unopinionated library that communicates with Ethereum and nothing else.That library must come in the form of a single, standard object available on all Ethereum browsers (such as Mist), in the same way that XMLHttpRequest is available on classic browsers, giving sites a way to perform HTTP requests.

Developers are, then, free to build high-level libraries on top of this object.Solution: a standard global function that just calls the JSON-RPC My particular suggestion is, thus, the simplest possible: a standard eth function, which, when called with a method name and a list of parameters, performs a RPC call to the Ethereum network and returns the result in a callback following the Node.js convention.This, for example, would be a "hello world" DApp using eth: Some things to notice: The check for Ethereum support is as simple as typeof eth !== "undefined".Methods such as .onconnect, .onopen are absent, because the connection is expected to be handled by the browser - i.e., the user choses what network to connect, not the DApp.The eth object is just a direct pipe to the RPC as it is.It doesn't do any kind of high-level manipulation or conversions.Results, for example, are sent in hex.Higher-level libraries build themselves on top of eth.DApp developers are able to use whatever high-level libraries they want.

If a high-level library updates, it won't break your DApp, because the only browser dependency is eth, which won't change.bitcoin cad price chartMiddleware interventions (such as Mist's pop-up asking the user permission to submit a transaction) can be done by simply decorating the eth function to be injected on the DApp's webview.bitcoin calculator in a poolThis repository This repository contains a demo implementation of the proposal above.buy bitcoin ottawaCheck example.js to see how you'd use it on Node.js.bitcoin hoodieThis is just a sketch, there is no real work performed on this yet, but it shouldn't be complicate since the proposal is, by definition, as simple as it gets.bitcoin plus to inr

Recently, the BTC/USD pair has greatly increased its volatility.bitcoin taxationThis remains true not only for Bitcoin, as such a tendency can be observed throughout the market of cryptocurrencies.bitcoin bull caseThere are no vivid factors that have impacted such movements.bitcoin blizzardTherefore, we can only assume that it is due to yet another correction and profit taking of the major market players.bitcoin owners memeAt the moment, the situation remains uncertain.What’s happening on the market: What to pay attention to: Ethereum is no exception.Last week, the $200 support zone proved to be right.However, at the moment, the price remains far from those levels.Potentially, the $320 zone looks good, though now Ethereum is trading lower.

Therefore, you need to wait for support levels to form, regarding the BTC/USD pair.There’s ICO, it seems to indicate investors’ interest in ETH.Another significant news is that the central bank of Singapore is planning to implement Ethereum Blockchain for tokenizing the national currency.While there are no clear levels, monitoring the price turns as well as the news is highly recommended.LTC has been trading in the $22-$35 channels since the beginning of May.Technically, everything remains exactly the same as it was last week.The $23 zone looks good for purchasing.Besides the technical analysis, follow closely the crypto market in general.Should the drop increase, LTC might be likely to be knocked out of its usual channel.If the knockout is below $22, it would be a strong signal for short positions opening.But due to the conjuncture in the current market, it might be better to play long positions.If there is a $22 blow and a rebound, it is a signal for long positions.Following this scenario, there might be the reversal opening the target at $33.

There’s been positive news for LTC.Just a few days ago, the creator of Litecoin, Charlie Lee, announced that he was leaving his position as Coinbase technical director in order to focus on Litecoin entirely.KeepKey just got a big upgrade!We are thrilled to announce support for Ethereum.Public beta begins this coming Friday, and we will amend this post with a link to the download when it is released.Update: Ethereum Beta is LiveDownload KeepKey WalletDownload KeepKey ProxyHardware Security For EthereumYou can now store ETH directly on KeepKey, and benefit from the same level of security other assets supported on KeepKey have enjoyed.This brings first-class security to Ethereum users worldwide.Multiple AccountsEthereum support includes all the features other assets like Bitcoin have in our Chrome Extension.This means you can create an unlimited number of Ethereum accounts, all residing on your single KeepKey and backed up with the same recovery sentence that backs up your other assets like Bitcoin, Litecoin, and Dogecoin.Full ShapeShift SupportThis release includes full ShapeShift support for Ethereum.
