Ask Hn: Lost $400k Usd In A Deleted Email, How Contact A Gmail Engineer? | Hacker News

Ask HN: Lost $400k USD in a deleted email, how contact a Gmail engineer? 139 points by lostethpresale 10 months ago | hide | past | web | favorite | 79comments On the 8th of June 2014 I purchased 1970 Ethereum from the Ethereum Foundation Presale and received an email to my Gmail account containing my wallet.As CS student overwhelmed by his thesis I managed to completely ignore the backup instructions and instead left my wallet in my Gmail account.At least the thesis was good :) You can probably tell where this story is going.I promptly forgot about this whole event and in 2015 while cleaning out my email account I deleted most of my recently received emails and incidently taking out the wallet with it.Again I'd like to state that the loss of the wallet is completely my fault. Recently, the price of Ethereum has skyrocketed to over 200 USD per coin, meaning the wallet is now worth ~400k USD.This means that I can now offer a nice bounty on its retrieval! I'm publicly posting here in the hope that someone from the Gmail team can check and see if they have a copy of the email saved in Google's backups.Should its contents be retrieveable, I'd like to offer 20% of the wallet's contents (~80k USD) as a finder's fee, alternatively if you choose to forfit this, I'll donate 50% (~200k USD) to a charity of your choice. I realise that this is a last ditch attempt and that wallet is most likely lost forever. This brings us to the morale of the story - "make sure you have backups and they work!"The 2nd morale is - "no matter how badly you mess up, at least you aren't the guy that deleted an email worth 400k!" If you work on Gmail and you can help or know someone that will lead to its retrevial please contact me [at] [email protected] If you want, you can encrypt your mail to m Continue reading >>

Ubiq (ubq) Wallet Generator: Open Source Javascript Client-side Ether Wallet

Ubiq (ubq) Wallet Generator: Open Source Javascript Client-side Ether Wallet

Verify you have access to this new wallet and have correctly saved all necessary information. Enter a strong password. If you think you may forget it, save it somewhere safe. You will need this password to send transactions. You should always back up your wallet externally and in multiple physical locations - like on a USB drive and/or a piece of paper. Save the address. You can keep it to yourself or share it with others. That way, others can transfer ETH to you. Save versions of the private key. Do not share it with anyone else. Your private key is necessary when you want to access your Ether to send it! There are 3 types of private keys: Keystore/JSON File (Recommended Encrypted Mist/Geth Format): This Keystore / JSON file matches the format used by Mist & Geth so you can easily import it in the future. It is the recommended file to download and back up. JSON File (unencrypted): This is the unencrypted, JSON format of your private key. This means you do not need the password but anyone who finds your JSON can access your wallet & Ether without the password. Private Key (unencrypted): This is the unencrypted text version of your private key, meaning no password is necessary. If someone were to find your unencrypted private key, they could access your wallet without a password. For this reason, encrypted versions are typically recommended. Place your address, versions of the private key, and the PDF version of your paper wallet in a folder. Save this on your computer and a USB drive. Print the wallet if you have a printer. Otherwise, write down your private and address on a piece of paper. Store this as a secure location, separate from your computer and the USB drive. Keep in mind, you must prevent loss of the keys and password due to loss or failure of you hard drive Continue reading >>

Accessing Your Ether Wallets Private Keys On Blockchain.info

Accessing Your Ether Wallets Private Keys On Blockchain.info

Accessing your Ether wallets Private Keys on Blockchain.info Currently, many companies support creation and use of Ether wallets. Its possible to send and receive ETH easily, without being need to download the whole Blockchain for the task. However, many of these wallets havent added support for ERC-20 tokens. These tokens are used often as a trading value in many ICOs, and also given to the users as payment for their contribution. With Chronologics ICO it wasnt different. There are steps to be taken to visualize and use these tokens for some wallets. Now, lets talk about the wallets that really allow users full control over their address. Among them we have Jaxx, MyEtherWallet, Blockchain.info, and others. If youve made your contribution from any of these rest assured that with a few simple steps you can manage and even transfer your DAY tokens. However, if youve sent your contribution from Coinbase, Bittrex, Poloniex, FreeWallet, BTC Markets or Kraken, among others, then you have a problem. In order to check the DAY tokens inside your ETH address, you dont need to unblock/open your wallet, rather only type your wallets address on EtherScan.io or Ethplorer.io. Now, if you really want to move your DAY tokens, or any other ERC-20 asset from those wallets, then youll have to access it using the Private Key, JSON file and password, etc. Today well feature a quick tutorial on how to recover your Private Key from an Ether wallet hosted by Blockchain.info. Step #1: Login into your Blockchain.info account. Step #2: Click on Ether (left side of your screen). Step #3: Select the option Export Private Key, as demonstrated below. Step #4: This warning mentions the implied risks of exposing your Private Key. Basically, never let anyone else see it and always double-check the websi Continue reading >>

Lost Private Key (keystore File)?

Lost Private Key (keystore File)?

I am new in mining, so here's my story:I installed Linux, downloaded geth and Claymore DualMiner.Then generated a wallet address with geth (I was asked a passphrase) and started mining ETH ... Meanwhile tried overclocking without success and decided to install windows + MSI Afterburner. So .. I have wallet and passphrase and lost keystore file. Is it worth get the missing info (keystore file) or just start from the beginning? What is in that file (maybe I can extract it with foremost like here: ) I already lost 2 days to get my data back (undelete, testdisk, foremost).I found some very old partitions and data, but what I seek was overwritten. About the keystore file and specifications: installed testdisk, listed my drives (the lost key was at /dev/sdc) I got a mass amount of data, where I found a JSON like text: UTC--2017-06-27T23-00-32.157422930Z--ea52e36ce9481bde98904d4307ba90cbc6cb8ac4 The ea52e36ce9481bde98904d4307ba90cbc6cb8ac4 is my account.

Lost Phone - Mobile Nem Wallet - Recovery Account

Lost Phone - Mobile Nem Wallet - Recovery Account

I lost my phone and now I have new one. I didnt any back up or something and when I did synchronization with my google account. Every app what I had on my lost phone were automatically installed and I thought that my old account on NEM wallet will be there but nothing was there. I dont have my private key but I have only password from this account and every information from my transaction what I did over changelly.com . Can you please help me with that? If you dont have backup your private key you cant restore your wallet. The password is enough only if you create brain wallet but mobile wallet doesnt use this method. The first thing after wallet creation should be to do a backup your private key Always! Your only hope is that files with your wallet are somewhere stored in Google backup, but if wallet didnt restore I dont think backup contains wallet files. Im sorry but it looks like that you lose your tokens together with your old phone. It isnt any database of all accounts where someone from NEM company can see my private key? I have every information except this Private key which is most important think I know. I know Number of transaction, Amount what I have there, transaction hashs and also when was money sent. I dont understant how it is imposible to help me with this. No. You are the only owner of a private key and only you have access to a private key. If you lose your private key you also lose your tokens. There is no internal storage with all private keys. This is way all blockchains working (bitcoin, ethereum, litecoin and so on). Also NEM. Thats why is so important to keep your private keys safe and do backups. Continue reading >>

New Windows 10 Version , Lost Ethereum Wallet.

New Windows 10 Version , Lost Ethereum Wallet.

New windows 10 version , lost ethereum wallet. Basically I've had a few ethereum coins on my laptop, I upgraded windows 10 to its newer version. I can't remember if I had windows 8 or 10 before but regardless I upgraded it and I totally forgot to backup my ethereum wallet that I had safed on the previous version. It doesnt let me go back to previous build as its been a few months so it doesnt display that option. Also windows.old folder is gone. Does anybody know how I could get it back? I don't think upgarding Windows versions will delete any application data or data in your user folder, so the wallet file should still be wherever it was previously. If you can't find the wallet file or you don't have a backup of it, then your coins are lost. This is a complete shot in the dark. There is a program called "shadow explorer". In a nutshell, it shows the files on your computer from previous dates. Had they been deleted or corrupt they can be restored to its previous condition. I've used it to restore a corrupted .dat from an alt. As for how far back it goes or whether or not it will contain files from before the upgrade is beyond me. No guarantees but its worth a go. Hope you get your coins back.. I dont use win10, but should he not need to reset his HD before installing win10 if he had win8 before? Is not just updating something is install fresh copy of operation system. You should store your ETH private keys before you were upgrading. Let me check how they look know are 3 files. they are in keystore folder. and looks something like "UTC--2016-02-14T23-23-00.7987987986767960Z...." You should get new ETH wallet on new operation system and then just patched this keystore folder into your ETH files and there would be your wallet. I guess you will know for next time. But in g Continue reading >>

Lost Wallet File [windows]

edited September 2015 in General Project Discussion (non-technical) Ethereum launched at the worst possible time for me. I had the biggest test of my life a few days after it launched, and I don't know code by any means. I had to try to balance learning how to mine and studying for the days up to my test. I was able to get 2 of my 280x's mining for the past month or so. I solo mined one block , and mined 87 or so Ether on ethpool.org. Today, at work, I went to go try to learn the basics of the currency to discover I did not have a keystore folder, and none of my ether I mined is accessible. The 87 or so Ether I mined is stuck on ethpool.org, and the other 5 are in a wallet that I cannot find, although I think they may be stuck on an Alethzero wallet that is apparently not the same format and not import-able into Geth. I am afraid I may have re-installed Ethereum and it deleted my keystore folder. I did not really know what I was doing at first, so I played with Eth++ and Alethzero, but finally landed on using geth and ethminer. Who knows what I did during that experimenting. Sadly, I've lost around 90 Ether or so, and I'm pretty devastated about it. I know both my public and private keys for each account. So I ask the community, is there a way to generate a wallet file with the public and private keys? I know counterwallet has a system like this. Is this at all possible, or will it be in the future for Ethereum? Is there hope for my Ether? Continue reading >>

'$300m In Cryptocurrency' Accidentally Lost Forever Due To Bug

'$300m in cryptocurrency' accidentally lost forever due to bug User mistakenly takes control of hundreds of wallets containing cryptocurrency Ether, destroying them in a panic while trying to give them back We are analysing the situation and will release an update with further details shortly, developer Parity told users.Photograph: Thomas White/Reuters '$300m in cryptocurrency' accidentally lost forever due to bug User mistakenly takes control of hundreds of wallets containing cryptocurrency Ether, destroying them in a panic while trying to give them back Last modified on Wednesday 8 November 2017 09.25EST More than $300m of cryptocurrency has been lost after a series of bugs in a popular digital wallet service led one curious developer to accidentally take control of and then lock up the funds, according to reports. Unlike most cryptocurrency hacks, however, the money wasnt deliberately taken: it was effectively destroyed by accident. The lost money was in the form of Ether, the tradable currency that fuels the Ethereum distributed app platform, and was kept in digital multi-signature wallets built by a developer called Parity. These wallets require more than one user to enter their key before funds can be transferred. On Tuesday Parity revealed that, while fixing a bug that let hackers steal $32m out of few multi-signature wallets, it had inadvertently left a second flaw in its systems that allowed one user to become the sole owner of every single multi-signature wallet. A cryptocurrency is a form of digital asset, created through a canny combination of encryption and peer-to-peer networking. Bitcoin, the first and biggest cryptocurrency, is part of a decentralised payment network. If you own a bitcoin, you control a secret digital key which you can use to prove to Continue reading >>

Securely Generating And Storing An Ethereumwallet

Securely Generating And Storing An Ethereumwallet

Securely Generating and Storing an EthereumWallet With the rise of Ethereum and Initial Coin Offerings (ICOs), especially ERC20 tokens , people unfamiliar with Ethereum or other cryptocurrencies like BitCoin are becoming interested in the technology. Unfortunately, getting started with Ethereum and participating in ICOs is not simple. The central component in Ethereum is the wallet. An Ethereum wallet is what holds your Ether and other Ethereum-based tokens, and conceptually can be thought of like a real wallet. Like a real wallet, an Ethereum wallet can be stolen. You shouldnt leave it out, or stored on a device that is often connected to the internet, or it risks being hacked. There is no recovery for a stolen wallet the courts cannot help you recover it, and you cant reverse what happens. This guide will explain how to safely generate and store an Ethereum wallet. MyEtherWallet is an open source project to make it simple to create an Ethereum wallet and interact with the Ethereum platform. It is hosted at myetherwallet.com , but its just a static web page. The safe, recommended way of using MyEtherWallet is to download the website yourself, so that there is no risk you go to the wrong website. This also allows you to use MyEtherWallet without being connected to the internet. You can download the latest version of the MyEtherWallet website as a zip file at this link . Download the etherwallet-v, not the chrome extension. When you unzip the file, you get a list of files containing a website. Unzipped MyEtherWallet. Double click index.html to openit. Open index.html to launch MyEtherWallet. Through the magic of mathematics, you can easily create a password-protected Ethereum wallet that no one will ever be able to duplicate accidentally. There are many more available E Continue reading >>

Meet The Man Who Will Hack Your Long-lost Bitcoin Wallet For Money - Coindesk

Meet the Man Who Will Hack Your Long-Lost Bitcoin Wallet for Money For Dave Bitcoin, the alias of the software architect that hacks peoples cryptocurrrency passwords, the price surge of Ethereums blockchain token ether has generated a significant amount of work; work that wouldnt have been steered his way without his focus on developing trust. And just to be clear, Dave Bitcoin hacks peoples passwords with their permission. He runs the website Wallet Recovery Services , which recovers peoples lost or forgotten passwords by brute force decryption that is, using a computer program to try millions of passwords in a short amount of time. He provides the service for bitcoin, litecoin and most other alternative cryptocurrency wallets, and in December, he began decrypting Ethereum pre-sale wallets. "I love a challenge," said Dave Bitcoin, whos pseudonym remains from the days when it was unclear if cryptocurrency was legal. "Initially, back in mid-2013, I just wanted to understand the cryptography used by bitcoin and the formats of encryption in the wallets. I realized that I was able to potentially help people who have forgotten their wallet passwords, and it grew from there." Dave Bitcoin has worked with more than 1,000 people since he launched the service, most in need of password recovery but a few that wanted deleted wallet files recovered. His success rate is about 30%, but its a rate that varies drastically based on how much information a client gives. Since January, Dave Bitcoin's Ethereum business has exploded, coinciding with the 1000% price increase. Today, about 50% of his business is decrypting Ethereum wallets, 40% is bitcoin related and the remaining 10% is recovering altcoin wallets, like litecoin or dogecoin. Dave Bitcoin charges 20% of the amount in the walle Continue reading >>

I opened mist wallet on May 3, i can't recall if a entered with Testnet. I did the back up and have the Keystore file with the files. I transferred ETH from Kraken but they never arrived, did not see them in my mist wallet. The transaction is visible on etherscan.io How can i restore the old account using the backup files? I opened myetherwallet and the backup file does not open there? Anyone know how to transfer funds from Mist to coinbase without syncing? Thread below: @Heleri Balances do not show until you have synced to the block your Kraken tx was sent to Mist. Were you fully synced before you sent the deposit from Kraken? @RiotAkt Your other option is to import your keys to Parity, but I would ask in their channels on the specifics. Hi , Someone could tell me how heavy the folder chaindata of mist, since it takes 60 gb and still I can not see my balance @PabDuart If you are doing fast sync, the chaindata folder should be less than 20GB. But you can only do fast sync in one complete sync, once you stop sync, fast sync is disabled if chaindata folder is not empty. You are looking at something around ~160GB for slow sync you are on. Delete your chaindata folder, start fresh sync and do not interrupt fast sync. Continue reading >>

How To Recover A Lost Wallet #396

How To Recover A Lost Wallet #396

As long as you remember your account password this might not be a problem. Your wallet and keystore data will be stored in %APPDATA%/Ethereum. Type that into a command-line shell to see the full path. I recommend making a backup copy of the keystore folder in there (as explained in ). After doing that you could try deleting %APPDATA%/Ethereum and then running the latest Mist (0.5.2) to recreate the folder with fresh data. You could then copy your keystore backup into the new %APPDATA%/Ethereum and restart Mist to see if it picks up your account. this is really frustrating, my computer crashed, I reinstalled the OS thinking if I have the password and the address I will be fine, I am not a computer geek, does this mean I lost my ethereum, all? I invested a lot of money in this technology and now I am told that I lost it all. I have my password which I thought it will be enough to "log in" back if I reinstall the wallet, I never knew this is a completely different technology which is not based on logins and I have never been prompted by any popup RED BIG saying: please save your wallet etc.!!! so, the questions is, what now? I just lost a few thousands ethereum?? Sigh, what a joke. When I used geth in February 2016, there was no mention that the software would put a private key in some random folder on my computer, while also downloading the entire ethereum blockchain. Well no duh I decided to delete a 10gig + folder on my hard drive when I needed space and was not an ethereum miner. All it said was to guard the password with my life. No mention to guard the private key with your life. No mention of putting super important files in a completely random directory. When people like myself or others are trying to promote Ethereum, we lose all our eth due to terrible documenta Continue reading >>
