By William Watts, MarketWatch 'No indication of wrongdoing,' exchange says It was a rough day for traders of the world's second-largest cryptocurrency on Wednesday as ethereum plunged from more than $317 to briefly trade as low as 10 cents in a flash cash on the GDAX exchange before rebounding.In a post, GDAX Vice President Adam White said a "multimillion-dollar market sell" order was placed on GDAX's ETH-USD [ethereum-U.S.dollar] order book, which resulted in orders being filled from $317.81 to $224.48--for a slippage of 29.4%.That, in turn, began a cascade of around 800 stop-loss orders and margin-funding liquidations, which sent the price temporarily as low as a dime, he explained.A stop-loss order requires the security to be sold when the price hits a certain threshold.Margin-funding refers to trading with borrowed money.Liquidations can occur when margin-funded positions are closed out automatically to prevent further losses.The combination of stop-loss orders and margin liquidations contributed to the sharp downward spiral, which was followed by a sharp rebound.

White said the GDAX decided to temporarily halt trading of ETH-USD in response to the price movement, then restored trading in accordance with the exchange's "downtime process" once it was confirmed that all systems were operating correctly.White said the exchange's initial investigations showed "no indication of wrongdoing or account takeovers" but acknowledged that such an event "can be frustrating for our customers."White said the exchange's matching engine "operated as intended throughout this event" and that "trading with advanced features like margin always carries inherent risk."And don't look for the trades to be reversed."We are continuing to conduct a thorough investigation and will keep customers updated with any resulting actions.With that in mind, it is important to note that these trades are final in accordance with our GDAX Trading Rules (Section 3.1)," White wrote."Honoring properly executed orders is critical to maintaining the integrity of an exchange."/story/how-cryptocurrency-ethereum-looks-set-to-overtake-bitcoin-in-one-chart-2017-06-14) Ethereum last traded at $326.94 on GDAX Thursday morning.

Coinmarketcap, a website that tracks market capitalizations for a variety of cryptocurrencies, said the total value of ethereum stood at $31.486 billion, second only to bitcoin at $44.475 billion.Ethereum has been on a tear in 2017 after beginning the year near $8.Investors have been excited by the network's blockchain, which many see as more versatile compared with bitcoin .bitcoin plus power miner/story/all-of-the-digital-money-in-the-world-in-one-chart-2017-06-07) - (END) Dow Jones Newswires Copyright (c) 2017 Dow Jones & Company, Inc.bitcoin almak satmakThe Alarm service is comprised of one normal contract and four library contracts.bitcoin calculator advancedVerification of the alarm source requires independent verification of each of these contracts.litecoin coming to mt gox

The source code for this release can be found 0.7.0 release on github To verify the compiled code of the contract, you will need to compile the source below with the solc compiler.You will likely need to use the same version used when deploying the contract, The source was compiled with the command solc --optimize --bin --bin-runtime contracts/* libraries/* with the command being run from the root of the github project.ethereum chart 2014This will produce unlinked source code, which means that there will be placeholders for the addresses of the library contracts.bitcoin japan adoptionYou can either compile with linking enabled or manually fill in the contract addresses above to get the compiled binary.To verify the source you check that the runtime bytecode associated with each of contract address equals the runtime binary output from the solc compiler.

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.Ethereum uses a public blockchain similar to Bitcoin, but also enables advanced programmable transactions types.Ether (ETH) is the primary currency on the Ethereum network.Much like bitcoin (BTC), it is created by computerized mining.Ether can be sent from one address on the Ethereum network to another, and can also be used in other transactions called ‘Smart contracts’’ Ethereum was proposed by Vitalik Buterin in a white paper.Since then many people have contributed work to the project.GDAX provides order books for both ETH/BTC and ETH/USD.You can create an account on GDAX to buy and sell ether with bitcoin, or US dollars.Bitcoin was conceived as a "A purely peer-to-peer version of electronic cash", focusing on payments, and value transfer as its primary applications.Ethereum extends the ideas Bitcoin is built on in order to provide a more generalized computational platform.

This enables the creation of smart contracts, decentralized applications, and even decentralized governance applications.Bitcoin and Ethereum are separate protocols, and it is not possible to complete a transaction from one to the other.However, you can buy and sell ether and bitcoin separately.Unfortunately if you send ether to an incorrect address, it may be lost forever.Ethereum network addresses do not have the safety measures, so it is possible to lose ether if you enter an address incorrectly.Bitcoin addresses have built-in verification to prevent errors like this.A smart contract is an executable program stored on the Ethereum blockchain.The execution of a smart contract is processed by miners, and requires a payment of ether in order to fund the processing of the contract.One or more parties can create or fund a smart contract, which will execute according to the inputs it receives.You can think of smart contracts are like a legal contract in that they specify an agreement for the handling of a given situation which may arise in the future, for example an insurance contract specifies the payout to the insured in the event of an accident.

Smart contracts differ from traditional legal contracts in that their execution is not subject to the interpretation of human institutions.A DAO is a type of contract that enables agents to purchase shares, and collaborate in the management of an organization by voting.Supporting this deposit type presents unique technical challenges and we are unable to recover ether deposited to your GDAX account in this way.We may support this in the future.In the meantime, you can deposit ether on GDAX from any standard ethereum address.At this time we do not support the functionality required to send funds to smart contracts directly from your GDAX account.This includes smart contracts like DAOs.GDAX is not a general purpose Ethereum wallet.When ether is sent to the receiving address for a DAO or other smart contract, tokens representing ownership are normally returned, however GDAX does not support retrieving assets other than ether which are sent to your GDAX account address.We may consider supporting other assets built on Ethereum in the future.

Like bitcoin, or any asset, ether has a value which can be used to trade for other assets, or good and services.Unlike Bitcoin, the development of Ethereum commerce has not been emphasized as a use case, and relatively few merchants accept ether.Although Ethereum has yet to have any major security flaws discovered, Ethereum is a young project, and loss of funds is a risk with the use of the Ethereum network in general.The Ethereum Foundation's legal agreement lists a number of these risks.The majority of ether and bitcoin deposited to GDAX is held in highly secure cold storage.It is also necessary to hold some digital currency in a "hot wallet" in order to provide fast access to withdrawals for customers.The total balance of bitcoin & ether in the GDAX hot wallets is insured against hacking and theft There are currently slightly more than 80 million ether in circulation, most of which was created during the initial crowd sale, prior to the launch of the Ethereum network.New ether is created and issued to miners at a rate of 21 million per year.
