Blockchain - What Are The Ethereum Disk Space Needs? - Ethereum Stack Exchange

How fast is Ethereum blockchain growing and how big is it likely to get in the future? Is it still about 1 GB per month? Are there any data pruning or compression algorithms in place? Latest Update: Nov 29th, 2017. I have written a blog post about this, esp. parity pruning modes: The Ethereum-blockchain size will not exceed 1TB anytime soon . Last Update: June 1st, 2017 / Block ~ 3800000 *) I wasn't able to synchronize any of the 5 clients below in unpruned node on a Quadcore-CPU VPS with 16 GB RAM on a HDD within a reasonable time. **) This is the default enabled mode of operation / pruning / synchronization. Go only offers database pruning on initial sync. The default --syncmode fast prunes old chain states and results initially in a database with around 20 GB in size. It is, however, expected to grow over time as the fast sync is only available once. ---------------------------------------------------------------------------| Sync-Mode | Database | Comment |===========================================================================| Light | 0.175 GB | --- |---------------------------------------------------------------------------| Fast** | 20.367 GB | Will grow consistently after initial sync. |---------------------------------------------------------------------------| Full | N/A | Wasn't able to sync this within 14 days*. |--------------------------------------------------------------------------- Parity offers continuous state trie pruning.

Frequently Asked Questions - Wiki Parity Tech Documentation

How to get Parity Ethereum in sync quickly? The quickest way of syncing Parity Ethereum client with the top of the chain is achieved using Warp sync in combination with warp-barrier. To make sure you get the most recent snapshot available and warp sync very close to the top of the chain, Parity Ethereum >=v1.10.1 supports the flag --warp-barrier [NUM]. Replace [NUM] with the chains latest block number minus at least 10,000 blocks. Example: if latest block number is 5,633,123 you should launch parity --warp-barrier 5620000. What are the Parity Ethereum disk space needs and overall hardware requirements? Running a full node with the standard configuration for the Ethereum Mainnet requires a lot of computer resources. The blockchain download and validation process are particularly heavy on CPU and disk IO. It is therefore recommended to run a full node on a computer with multi-core CPU, 4GB RAM and an SSD drive and at least 100GB free space. Internet connection can also be a limiting factor. A decent DSL connection is required. Computers using HDD are advised to run a Light Node . Running a light node using the flag --light does not require to download and perform validation of the whole blockchain. A light node relies on full node peers to receive block headers and verify transactions. It is therefore far less resource demanding than a full node. A computer or mobile phone with single core CPU, 512MB RAM and an HDD with 128MB free space are recommended to run a light node.

What Is An Ethereum Testnet And How Is It Used?

What Is An Ethereum Testnet And How Is It Used?

What Is an Ethereum Testnet and How Is It Used? In this post we'll briefly explain Ethereum testnets what they are, what they're used for, and how they're used. For a better understanding of the content that follows, it's recommended you read the following introductory articles: When writing programs for the EVM (Ethereum Virtual Machine), i.e. the Ethereum blockchain, we need to pay for their launch and usage in gas . This cost can be prohibitive in times of network overuse and it can also be financially dangerous a bug deployed on the live network is a bug forever open to abuse. Any change on the Ethereum blockchain is permanent and cannot be undone. Testnets are copies of the Ethereum blockchain almost identical in every way to the Mainnet except in the fact that their Ether is worthless (and, of course, the software that's been deployed on these testnets). Public testnets are available to everyone, they're connected to the internet. Anyone can connect to them at any time, even from popular wallet interfaces like MyEtherWallet or MetaMask. The following public testnets are available: In the MyEtherWallet interface, they're marked with a yellow edge. Each has two nodes you can connect to (doesn't matter which one you pick both lead to the same network). The same testnets are available through MetaMask: Ropsten was launched in November 2016. Its Ether can be mined just like on the Mainnet. Both Geth and Parity support it two different implementations of the Ethereum node software so it's possible to develop for it from two different angles. Of all three testnets, Ropsten resembles the current Mainnet the most. Its results resemble Mainnet results because its consensus mechanism is PoW (i.e. it can be mined on) so the simulation of transaction confirmations is the most Continue reading >>

Ethereum Wallet Review 2017:the Official Wallet For Eth | Finder.com

The Ethereum Wallet is free to download and use, although it will cost you some time and space on your hard drive to download the blockchain. You will most likely need to pay transaction fees in order to send ether over the network, although there is a flexibility feature built in to give you some control over fees in relation to transaction priority. Digital tokens issued on the Ethereum platform The Ethereum Wallet is found within a larger application called Mist. Mist is a web browser designed to interact with decentralized applications (DApps) running on the Ethereum network. The Ethereum Wallet is one application built into Mist, and youll need to run Mist in order to use the Wallet. Its important to note that Mist is still in beta, and its up to users to stay informed about bug fixes, software updates and other potential issues by checking in with official Ethereum channels. Ethereum is a young project, and many elements of the Ethereum platform are still under development. A lot of the existing infrastructure that enables users to interact with Ethereum is designed primarily for developers and those with a fairly advanced technical skillset. Fortunately, however, the official Ethereum Wallet does come with a simple graphical user interface (GUI) and its not too difficult to get it up and running. Heres how: Before you can add currency, you will need to download the latest version of the Ethereum Wallet. The safest and easiest way to do this is to use the link on the official website . If the download doesnt start automatically, you may be taken to Ethereums GitHub page. Scroll down until you find the appropriate download for your operating system. Once the download has completed, you can launch the Mist application. Youll be prompted to choose between using the Continue reading >>

Your Ethereum Node Web3.py 4.8.1 Documentation

Your Ethereum Node Web3.py 4.8.1 Documentation

You can find a fuller list of node software at ethdocs.org . Some people decide that the time it takes to sync a local node from scratch is toohigh, especially if they are just exploring Ethereum for the first time. One way towork around this issue is to use a hosted node. The most popular hosted node option is Infura .You can connect to it as if it were a local node,with a few caveats. It cannot (and should not) host private keys foryou, meaning that some common methods like w3.eth.sendTransaction() are not directly available. To send transactionsto a hosted node, read about Working with Local Private Keys . Once you decide what node option you want, you need to choose which network to connect to.Typically, you are choosing between the main network and one of the available test networks.See Which network should I connect to? MetaMask is not a node. It is an interface for interacting with a node.Roughly, its what you get if you turn Web3.py into a browser extension. By default, MetaMask connects to an Infura node.You can also set up MetaMask to use a node that you run locally. If you are trying to use accounts that were already created in MetaMask, see How do I use my MetaMask accounts from Web3.py? Once you have answered How do I choose which node to use? you have to pick which networkto connect to. This is easy for some scenarios: if you have ether and you wantto spend it, or you want to interact with any production smart contracts,then you connect to the main Ethereum network. If you want to test these things without using real ether, though, then youneed to connect to a test network. There are several test networks tochoose from. One test network, Ropsten, is the most similar to the production network.However, spam and mining attacks have happened,which is disrupti Continue reading >>

Ethereums Rapidly Increasing Blockchain Size Sparks A Debate About Decentralization

Ethereums Rapidly Increasing Blockchain Size Sparks A Debate About Decentralization

Ethereums Rapidly Increasing Blockchain Size Sparks a Debate About Decentralization The increasing size of Ethereum blockchain could soon become a potential problem. Miners running Ethereum full nodes have reported difficulties in synchronizing them. One miner, for example, pointed out that their geth node running the latest version 1.8.1 fails to sync the last 65 blocks. Another complaint read that the node always failed to sync with the current state of the Ethereum blockchain. A reason for this failure could be Ethereums ever-growing blockchain size, which is reported to have exceeded 1 Terabyte (TB). The size represents the amount of data that has to be validated and synced by all full nodes running on the network. If one were to run an Ethereum full node, he would need at least 1TB of vacant disk space and that much of bandwidth to download that much data in a reasonable time frame. The speed at which nodes sync with the main chain is dependent on hardware capabilities of the host machine and its internet speed. On June 11, 2017, it was observed that the size of the Ethereum blockchain had risen by 700 percent between June 2016 and June 2017 to reach 160GB. The same source predicted that if it continued to grow at the same rate, it would reach 1TB by June 2018. The prediction has turned out to be accurate. On May 23, stopanddecrypt published a Medium post outlining the issues with Ethereum and providing a commentary on these issues, while experts of the blockchain network provided their response. Why Ethereums Growing Blockchain Size is a Problem There are two versions of the Ethereum blockchain nodes available to download. One is the full version while the other is the light version. The light version of the node contains only headers of the most recent transacti Continue reading >>

Ethereum | Ecm Architect

Jeff Potts' personal blog about Alfresco, content management, BPM, search, and other stuff Ive been exploring blockchain technology lately. In this post Ill share what Ive learned so far. I should point out that my interest is squarely on how blockchain can be applied to solving business problemsIm less interested in cryptocurrency. A blockchain, as the name suggests, is a linked chain of blocks. Each block contains arbitrary data and a link to the previous block. Because these links are created using cryptographic hashes, blocks are hard to alter. The chain is continuously growing. Transactions run which add new blocks, and those transactions are validated by other servers before they are accepted into the chain. So a blockchain is like a database, but instead of running on a central server controlled by a single entity, the blockchain is distributed across many servers, and, depending on which blockchain you are talking about, the blocks in the chain may be visible to the public. The reason blockchain is often referred to in the context of cryptocurrency is because cryptocurrencies use a blockchain as a distributed ledger to track cryptocurrency trades. But that is only one of many possible use cases. Wrapping up this brief intro, realize there is no single blockchain. You can run your own private blockchain internally. Or, you could set up a private blockchain between your company and your partners. Or, you could leverage one of the public blockchain networks. It really depends on exactly what you are trying to do. For more on the origins of blockchain, see The Wired Guide to the Blockchain . To identify problems that are good candidates for blockchain applications it helps to summarize the technologys most noteworthy characteristics: Data blocks are immutable. Once Continue reading >>

Blockchain Bloat: How Ethereum Is Tackling Storage Issues

Blockchain Bloat: How Ethereum Is Tackling Storage Issues

Blockchain Bloat: How Ethereum Is Tackling Storage Issues Jan 18, 2018 at 05:22 UTC|UpdatedJan 24, 2018 at 02:53 UTC 24,270 tokens. 27,358 pending transactions. 463,713 digital kittens . Ethereum has hosted a lot of activity recently, and while many crypto enthusiasts see that as a positive sign, as the network's usage soars, its history gets longer and its blockchain more unruly. And although network congestion leading to transaction backlogs and rising fees has taken the spotlight, there's another issue this scale causes - a growing database that puts significant storage costs on users wanting to run a full node. That database, called the ethereum state, hold all the computations that need to be memorized by the computers supporting the platform and the ethereum blockchain itself. And with the costs (both in time and money) of storing the state increasing, fewer and fewer people are choosing to run full nodes, which many worry will centralize the network into the hands of only a few arbitrators. For one thing, ethereum developers are well underway engineering protocol-level changes such as sharding , aimed at minimizing the database. But since these technologies are still in development, other stakeholders, namely those running ethereum clients - the software needed for users to communicate with the blockchain - have been under fresh pressure to cope with the growth of the state database. "The fact that improving this stuff is critical has been known since late 2016, the ideas have been floating around for half a year to over a year. Where are the implementations?" said ethereum creator Vitalik Buterin on a developer channel recently. The frustration is palpable with both Buterin and Afri Schoedon, who manages technical communications at ethereum software client prov Continue reading >>

How To Delete Geth Chaindata & Resync

How To Delete Geth Chaindata & Resync

Home Guides Clients How To Delete Geth Chaindata & Resync Go-Ethereum (Geth)is one of the many Ethereum clients . It is developed by developers from the Ethereum Foundation . The core features of Ethereum web 3.0 stack are expected to arrive at Geth first. In this guide, the procedure for re-syncing Gethon Windows will be shown. I am usingGeth 1.5.4 (latest stable version as of 30 Nov) on my Windows 10 machine. Note: If you have not installed Geth, please install Geth using the instructions here: How To Install Geth In Windows . Resync of the blockchain has the benefit of reducing the amount of disk space used by Geth. The deletion of chaindata folder and resyncing of the blockchain will not be needed once Geth has employed state-tree pruning which will automatically archive old blocks to reduce disk usage. Until Geth has included this functionality, the regular deletion of chaindata folder and resyncing of blockchain is recommended to keep the disk usage at minimum. The chaindata folder is located atC:\Users\\AppData\Roaming\Ethereum\geth\. Yes, delete the whole folder. Do not worry. Your Ethereum account will NOT be deleted (they are stored in another location). Step 3: Run Geth with the -fast -cache=1024 flags If you do not know how to set the flags, please usethe instructions here (Under Step 4): How To Install Geth In Windows . Step 4: Wait for Geth to complete the fast sync Fast sync is completed when Geth starts to import 1 block at a time. Continue reading >>

Storj - Decentralized Cloud Storage

"Storj is like an Internet filesystem. Data blocks are encrypted and distributed across a globally distributed set of storage nodes using block-chain algorithm. It is quite impressive and much needed innovation in the storage space." "Decentralized file storage systems like Storj have the potential to eliminate high markup costs and market inefficiencies and provide a much higher level of privacy, reliability and quality of service than we see today." "The power of the Storj platform is its unique ability indiscriminately utilize the free capacity of a storage node, whether a single end-user PC or a massive data center. Storj is bringing an unprecedented degree of efficiency to globally distributed data storage." "Storj is a unique market phenomena. It sets new standards of unit economics for distributed data storage." "As a seed investor, we were more than happy to join the next round for Storj with a great line up of co-investors. We want storing files to be cheaper, faster and more secure and the progress the team has made towards that mission has been phenomenal to watch. We are looking forward to putting more and more of our documents on the Blockchain thanks to Storj." Continue reading >>

Talk Crypto Blog Ethereum

Ever wanted to receive payment with a cryptocurrency and then enable an action such as open a door or turn on a light? Here is a quick overview of how this can be done with Ethereum, a Raspberry Pi and Nodejs. Summary The idea is to display a QR code on a tablet where payments can be made with crypto and upon receipt of payment an LED is turned on. The webpage is running on a Raspberry Pi which is also running geth which is the Ethereum blockchain client. The neat thing is that there is an experimental light sync mode that only obtains the current blockchain state and only requires ~400Mb of disk space. See it in action In the video above I use Metamask to make the test ether payment. It takes about 30 seconds for the transaction to be acknowledge and the LED to light up. Html Payment Page The payment page basically consists of a QR code for the user to make a crypto payment and in the background, it connects to the local Ethereum blockchain to get the current balance and to listen for the next block to arrive. When it does, it queries the [] Interested in getting Ethereum running on a Raspberry Pi 2?

The Ethereum-blockchain Size Will Not Exceed 1tb Anytime Soon.

The Ethereum-blockchain Size Will Not Exceed 1tb Anytime Soon.

The Ethereum-blockchain size will not exceed 1TB anytime soon. Before diving into this article, please read the two disclosures about my involvement (1,2) and the one on data accuracy (3) at the bottom of the article. At least once a month someone posts a chart on r/ethereum predicting the blockchain size of Ethereum will soon exceed 1 TB. I want to take that chance to clean up with some stories around the Ethereum-blockchain size in this article and try to explain why this chart is technically correct, but not the full picture. Let's have a look at this chart first. It shows the complete data directory size of an Ethereum node (red), Geth in this case, and a Bitcoin node (blue), probably Bitcoin-Core , plotted over time. While the Bitcoin graph is moving slightly upwards in a seemingly linear inclination, the Ethereum graph reminds the reader of an exponential growing slope. On Blocks, Block-History, States, and State-History Users accusing Ethereum of blockchain-bloat are not far off with their assumptions. But actually, not the chain is bloated but the Ethereum state. I want to examine some terminology from the Whitepaper before proceeding. Block. A bundle of transactions which, after proper execution, update the state. Each transaction-bundling block gets a number, has some difficulty, and contains the most recent state. State. The state is made up of all initialized Ethereum accounts. At the time of writing, there are around 12 million known accounts and contracts growing at a rate of roughly 100k new accounts per day . Block-History. A chain of all historical blocks, starting at the genesis block up to the latest best block, also known as the blockchain. State-History. The state of each historical block makes up the state history. I will get into the details on t Continue reading >>

The Ethereum-blockchain Size Has Exceeded 1tb, And Yes, Its Anissue

The Ethereum-blockchain Size Has Exceeded 1tb, And Yes, Its Anissue

The Ethereum-blockchain size has exceeded 1TB, and yes, its anissue (TL;DR: It has nothing to do with storage spacelimits) This is an indirect response to the following article by Afri Schoedon , a developer for the Parity Ethereum client, written less than a year ago: Once a month users post a chart on `r/ethereum` predicting the blockchain size of Ethereum will soon exceed 1 TB. Idev.to I want to make it clear that I have respect for almost all of the developers in this space, and this is not intended to attack anyone. Its meant to elaborate on what the real concerns are and explain how the original article does nothing to address those real concerns. I would actually love to see something that does, because then we can throw it into Bitcoin . That being said, there are some developers who mislead, obscure, ignore, and attack via protocol confusion like what occurred with 2X and the replay protection drama , but most arent like that. You cant watch something like this or read something like this and hate these developers. Theyre genuinely trying to fight the same fight as us, and I believe Afri is part of the latter group, not the former. If youve read my other articles youre going to see some small bits of that information repeated. Up until now I wrote primarily about Bitcoin from a maximalist perspective (still am) and focused on conflicts within that community. What you may find interesting if you only watch from the corner of your eye, is that the reason for conflict here is exactly the same. Ill even use Proof-of-Stake as further leverage for my argument without criticizing it. Edit: It seems like people are not reading the subtitle and misunderstanding something. This is not about archival nodes. This is about fully validating nodes. I dont care if you prune t Continue reading >>
