How To Fix Ethereum Mist Wallet Never Ends Syncing

How To Fix Ethereum Mist Wallet Never Ends Syncing

How To Fix Ethereum Mist Wallet Never Ends Syncing I had an issue with the Ethereum Mist wallet never finishing syncing the blockchain. Mist just kept downloading chain structure for two days, always stuck a couple of hundred blocks behind the most current one. Download the latest version of Geth and extract it to somewhere like C:\Geth ( ) Run CMD.exe (Command Prompt, the black terminal window in Windows) as Administrator (right-click -> Run as Administrator) Change directory to where you extracted Geth: Run the following command to start syncing the blockchain using the light syncmode: It should now start syncing. After a while (how long varies), you will notice it reaches the current block and becomes less active. You should now be able to run the Mist wallet without issues again. Download and run the latest Mist wallet to avoid other bugs/issues ( ) Hope this helps someone out there with the same annoying issue! Continue reading >>

Which Ethereum (lightweight) Wallet

Which Ethereum (lightweight) Wallet

I need to make an Ethereum payment Monday so I'm looking for a good wallet. I've made several attempts in the last months to start an Ethereum wallet and finally I gave up (took daaays each time and failed in the end). I would like to hear some advice on which wallet to choose. I'd need to make a payment by Monday, so if it needs to sync 2 days again I want to start today... -is the official Ethereum wallet the way to go? I tried with the GUI version, but had no success (even on a pc with ssd) -online wallets? I need the wallet to make a payment for an ICO (Bancor) but the payment cannot come from an exchange. So I assume it cannot come from (eg) Poloniex, but is Coinbase or CEX.io allowed? Jaxx will be fine for what you want to do. But the problem is where to store your ERC20 tokens. I assume you need to download Parity or another Ethereum client and download the whole blockchain which is really huge from what I have heard. How about this wallet : I am using online wallet myetherwallet.com How about this wallet : so with myetherwallet.com, you can send funds to an ICO because it's a wallet and not an exchange? INRI666: I hadn't heard about the ERC10 tokens, I have no idea what will happen if I transfer some money to the ICO for Bancor. I assumed they'd contact me with further instructions? Or will these tokens be sent to the same ethereum wallet? Sorry, haven't got much experience with the cryptoworld , especially with ICO...

Light Client Protocol

Light Client Protocol

The purpose of the light client protocol is to allow users in low-capacity environments (embedded smart property environments, smartphones, browser extensions, some desktops, etc) to maintain a high-security assurance about the current state of some particular part of the Ethereum state or verify the execution of a transaction. Although full security is only possible for a full node, the light client protocol allows light nodes processing about 1KB of data per 2 minutes to receive data from the network about the parts of the state that are of concern to them, and be sure that the data is correct provided that the majority of miners are correctly following the protocol, and perhaps even only provided that at least one honest verifying full node exists. All substantial quantities of data in Ethereum are stored in a data structure known as the Patricia Merkle tree , a tree structure where each node in the tree is the hash of its children. Each set of key/value pairs maps to a unique root hash, and only a small subset of nodes is needed to prove that a particular key/value combination is in the tree corresponding to a particular root hash. The size complexity of a Merkle proof scales linearly with the height of a tree; because each child in a tree has a particular number of children (in our case, up to 17), this means that the size complexity of a Merkle proof is logarithmic in the quantity of data stored. This means that, even if the entire state tree is a few gigabytes in size, if a node receives a state root from a trusted source that node has the ability to know with full certainty the validity of any information with the tree by only downloading a few kilobytes of data in a proof. An SPV proof of a node in a Patricia tree simply consists of the complete subset of tree Continue reading >>

Use Crypto Wallet Without Downloading The Entireblockchain

Use Crypto Wallet Without Downloading The Entireblockchain

A blockchain essentially made up of a linear series of blocks, each of which primarily consists of (among others): Block Header (containing a reference to the Previous Block Hash, a Merkle Root, and a few other elements). Transactions (a list of all transactions included within the block). To validate a particular transaction, all the preceding incoming and outgoing transactions, to and from the senders address, need to be tracked. In order to do so, a wallet needs to download the entire blockchain locally on the device. This is a one time activity, as later, the software has to only update the blocks that it hasnt downloaded before. This is exactly what a traditional thick-client wallet does. But as the number of transactions grow exponentially, downloading an entire list of transaction records (blockchain) could become inconvenient. To tackle the issue, a technique known as Simplified Payment Verification (SPV) can speed up the verification process to a large degree. And wallets which implement this technique are known as SPV (thin-client) wallets. The list of transaction records included within a block, can be arranged in the form of a Merkle Tree , created from the hash values of those transactions. Thus, the root node (called the Merkle Root) of this tree has a reference to all of the transactions contained in the specific block. SPV wallets just download the block headers of all the blocks included in the blockchain, which is collectively much smaller in size, compared to the full blockchain. To verify a transaction, the light (or SPV) client requests for the Merkle Root of the block (in which the transaction belongs to), from certain full nodes in the blockchain network. The client also requests these nodes for the minimum information (hashing partners) required Continue reading >>

Advanced Ethereum Walletusage

Your lighthouse in the rough seas of circumstance 15/12/2017 by andersguide in Uncategorized Leave a comment This article will expand on the information about the Go Ethereum wallet found in my article about cryptocurrency mining . I will provide some suggestions you can try if you have problems with your wallet and well take a look at advanced ways to use the wallet. If the wallet synchronization process is not working, there are a few steps you can try to find the error. Assuming that you are using the light client mode as recommended in my cryptocurrency mining article , the first thing to try is to wait for a few hours and see if a connection to the Ethereum network is established. If your wallet still will not synchronize despite waiting, try to turn the light client mode off (just untick the Sync with Light client (Beta) option in the Develop menu of the wallet, see image below). This should allow your wallet to synchronize, although the process will now take dozens of hours and require 50+ GB of space since you will do a regular synchronization instead of a light one. If turning the light client mode off does not relieve your problems with wallet synchronization you may want to try using the command line interface (CLI) to synchronize with the Ethereum network. This method will give you more information about what is actually going on. To start using the CLI, we will need to dig a bit deeper into the inner workings of the Ethereum wallet. Lets take a look at geth. The program that actually takes care of the wallet interaction with the Ethereum network is called geth (short for Go Ethereum). When the Ethereum wallet is opened it will automatically check for the most recent version of geth and download this version if it is not already available on your computer. Continue reading >>

Best Ethereum Wallet (2018 Update) 5 Options Reviewed

Last updated on November 24th, 2017 at 08:15 am Ethereum, the blockchain platform that allows smart contracts, is becoming more and more popular.Since the beginning of 2017 the price has spiked from $8.22 to around $50. Ive covered how to buy Ethereum in a previous post but thats only part of the process. Today I want to cover 5different types of Ethereum wallets so you will know where to store your Ethereum. Ethereum is a very technical currency (even more than Bitcoin), therefore most wallets out there arent newbie friendly. I will go over them from the simplest to the most complex so you can choose the one that is best suited to your knowledge level. Hardware wallets Best security (for a price) If youre serious about securing your altcoins I suggest storing your Ethereum on a hardware wallet. However these hardware wallets arent free and cost anywhere between $50-$100 (shipping not included). Todays leading hardware wallets TREZOR , Ledger and KeepKey all supply you with the option to store Ethereum on them. Instead of explaining about each one Ill just link to my previous reviews on the wallets: Personally, I use a TREZOR but all three are excellent choices for maximum security. Coinbases Ethereum wallet The simplest option Coinbase supplies an Ethereum wallet as well as a Bitcoin wallet. Coinbases wallet is simple to set up and very easy to use, however it has a few limitations youll need to be aware of: The company holds the private key ofthe wallet for you. This means youre not in control of your funds and Coinbase can decide to shut down your account if they want to. There were cases in the past that Coinbase shut down user accounts do to illegal activity. The Coinbase ETH wallet doesnt support ETC (Ethereum Classic). For a simple explanation about ETC vs ETH r Continue reading >>

I'm a serial entrepreneur. I enjoy AI, UI, and blockchain. I like history and reading too. This is a basic way to setup Ethereum light client with private network. I will talk about 3 things. Light client is an ethereum client which keeps only keys. You can check accurate definition here . Traditionally in blockchain world, everyone keep same databases. Thats why we can trust entire system. I mean we can trust at least our own data. But light client dont keep data. But problem is keeping entire database is tough. When I created an ethereum wallet first time I needed to download entire ethereum database. That syncing process took almost whole day and the file size was huge. A web site said the storage size was more than 75GB in 2016 and was growing 1GB per month. This is insane and only blockchain enthusiast can keep it. You can not run ethereum full node on mobile devices. Or normal users dont want to keep full node on their devicesanyway. Thats why we need light clients. With light clients, user dont need to keep ethereum node. They can just enjoy decentralized services. This is pretty cool. I experimented light client with my private network. Because we can develop dapps for mobile, this has a huge potential. You need at least 1 ethereum node. Since light client dont run ethereum node, we need to run nodes for clients to connect. I installed geth which is Go implementation of the Ethereum protocol. I think geth is most popular. You can check how to install geth here . Once you install geth, you can setup private network. First, you have to prepare genesis block. You can easily create new genesis block with a command line tool called puppeth which is installed with geth. Heres my example. I choose proof of authorization as my consensus algorithm because I dont want he Continue reading >>

Wallets For Ethereum: An Overview

Wallets For Ethereum: An Overview

With which software can you use Ethereum? Which runs on a mobile phone, which on Linux? Which is good for storing ether, which for tokens, and which can interact with Smart Contracts? We present you a list of wallets for every device and need. While there are dozens of wallets for bitcoin, providing a broad range of choices for every system, Ethereum has only a handful of wallets. However, there are enough to let everybody, from beginners to experts, use Ethereum, with any system, be it a smartphone or a high-end computer. Like with Bitcoin , real nodes are full peers in the Ethereum network. Using it is the most autonomous and direct method to interact with the Ethereum network. Real nodes provide the highest degree of privacy and the widest scope of options. Everything that can be done with Ethereum can be done with a node. You can completely interact with and deploy any kind of smart contract. However, the price for using a full node is a rapidly growing demand on system resources. Here we present the two most popular Ethereum full node clients; Geth and Parity. Both run as a daemon on the system while providing the option to access the blockchain and your wallet with an optical interface. The Ethereum implementation in the language Go is more or less the official client of Ethereum. Around 20,000 Geth nodes are the backbone of the Ethereum network; when the developers agree on new features, they are usually implemented first on Geth, like recently Swarm. You can say, that right now, Geth defines the consensus of Ethereum. If you want to use Geth as a wallet, you can start the Ethereum Wallet or the Web3 Browser Mist . Both share the same graphical interface. With them, you can easily manage your ether and your tokens. Also, the interface allows you to watch, write Continue reading >>

How To Use Ethereum - Coindesk

How To Use Ethereum - Coindesk

The thought of using ethereum might sound intimidating, but it could be rewarding. If the 'unstoppable world computer' develops according to plan, it could provide alternatives to the Facebooks and Googles that many people use everyday(as explained in " What is Ethereum? "). Ethereummight not be as intuitive as the web as we know it today, but still, anyone with a computer or a smartphone can try the platformout as long as they own ' ether 'unique pieces of code that allow updates to the blockchain's ledger. First, you need a place to securely store your ether (or at least a place to store your private keys). This brings us to ethereum 'wallets'. One caveat is that losing your private key is a much bigger deal than misplacing a password: it means losing your ether, forever. Removing trusted partiesis a two-edged sword. While intermediaries are no longer needed to verify transactions, there's no help desk to turn to for help recovering your secret key. With that in mind, there are plenty of options for wallets to store cryptocurrency: desktop wallets, web wallets, hardware wallets and paper wallets. Choosing one depends on your preferences for convenience and security. Usually these two concepts are at odds with one another: the more convenient, the worse the security (and vice versa). Desktop wallets run on your PC or laptop. One option is to download an ethereum client (a copy of the entire ethereum blockchain). There are a few ethereum clients written in different programming languages and with different performance tradeoffs. This process can take up to a couple days, and will only increase as ethereum grows. The wallet then needs to stay in sync with the latest transactions on the blockchain. Mobile clients, or 'light' clients, require less data to be downloaded to Continue reading >>
