If you lose the password you use to encrypt your account, you will not be able to access that account. Repeat: It is NOT possible to access your account without a password and there is no forgot my password option here. Do not forget it. The ethereum CLI geth provides account management via the account command:. Manage accounts lets you create new accounts, list all existing accounts, import a private key into a new account, migrate to newest key format and change your password.

It supports interactive mode, when you are prompted for password as well as non-interactive mode where passwords are supplied via a given password file. Non-interactive mode is only meant for scripted use on test networks or known safe environments. Make sure you remember the password you gave when creating a new account with new, update or import.

Without it you are not able to unlock your account.

Installing Geth

Make sure you backup your keys regularly! If a custom datadir and keystore option are given the keystore option takes preference over the datadir option. The order of accounts when listing, is lexicographic, but as a consequence of the timespamp format, it is actually order of creation.

It is safe to transfer the entire directory or the individual keys therein between ethereum nodes. Note that in case you are adding keys to your node from a different node, the order of accounts may change. So make sure you do not rely or change the index in your scripts or code snippets. Accounts can also be managed via the Javascript Console. You supply a plaintext password file as argument to the --password flag. The data in the file consists of the raw characters of the password, followed by a single newline.

Note : Supplying the password directly as part of the command line is not recommended, but you can always use shell trickery to get round this restriction. The account is saved in encrypted format. You must remember this passphrase to unlock your account in the future. For non-interactive use the passphrase can be specified with the --password flag:. Note, this is meant to be used for testing only, it is a bad idea to save your password to file or expose in any other way. The keyfile is assumed to contain an unencrypted private key as canonical EC raw bytes encoded into hex.

Therefore you make sure you either do not rely on the account order or doublecheck and update the indexes used in your scripts. Warning: If you use the password flag with a password file, best to make sure the file is not readable or even listable for anyone but you. You achieve this with:. You can update an existing account on the command line with the update subcommand with the account address or index as parameter. You can specify multiple accounts at once.

The account is saved in the newest version in encrypted format, you are prompted for a passphrase to unlock the account and another to save the updated file.This document explains how to set up geth for mining. The Ethereum wiki also has a page about miningbe sure to check that one as well.

Mining is the process through which new blocks are created. Geth actually creates new blocks all the time, but these blocks need to be secured through proof-of-work so they will be accepted by other nodes. Mining is all about creating these proof-of-work values.

The proof-of-work computation can be performed in multiple ways. Geth includes a CPU miner, which does mining within the geth process. We discourage using the CPU miner with the Ethereum mainnet. If you want to mine real ether, use GPU mining. Your best option for doing that is the ethminer software. Always ensure your blockchain is fully synchronised with the chain before starting to mine, otherwise you will not be mining on the correct chain and your block rewards will not be valueable.

If you get Error GPU mining. GPU memory fragmentation? To get ethminer, you need to install the ethminer binary package or build it from source. At the time of writing, ethminer only provides a binary for Microsoft Windows. Follow the prompts and enter a good password. Also take note of the public Ethereum address which is printed at the end of the account creation process. You can change this by giving the --rpcport option to geth.

Ethminer will find get on any port. Setting up custom ports is necessary if you want several instances mining on the same computer. If you are testing on a private cluster, we recommend you use CPU mining instead.

Private Networks

If the default for ethminer does not work try to specify the OpenCL device with: --opencl-device X where X is 0, 1, 2, etc. When running ethminer with -M benchmarkyou should see something like:. Note hashrate info is not available in geth when GPU mining. Check your hashrate with ethminerminer. When you start up your ethereum node with geth it is not mining by default.

To start it in mining mode, you use the --mine command-line flag. The --minerthreads parameter can be used to set the number parallel mining threads defaulting to the total number of processor cores.

You can also start and stop CPU mining at runtime using the console. Note that mining for real ether only makes sense if you are in sync with the network since you mine on top of the consensus block.

In order to earn ether you must have your etherbase or coinbase address set. This etherbase defaults to your primary account. Note that your etherbase does not need to be an address of a local account, just an existing one.The history of the geth's creation and evolution serves as a warning to the rest of the galaxy of the potential dangers of artificial intelligence and to the legally enforced, systematic repression of artificial intelligences throughout galactic society.

Geth are primarily composed of two materials: a flexible but durable outer shell, and a kind of synthetic muscle tissue that gives Geth Hoppers their incredible agility.

It is actually possible for this synthetic muscle to be grafted to organic tissue Saren Arterius has a grafted geth arm. Geth "bleed" a white conductive fluid when shot, but they don't have any internal organs or nervous system, so the geth do not feel hunger or pain. The geth are also seen using omni-toolsand have seemingly modified them to heal synthetic wounds; likewise, some geth facilities contain first-aid kits, implying that their synthetic "tissues" can be repaired using conventional medical technology.

Part of the geth's success is due to their neural network.

Effectively, they "share" their processing power, distributing low-level processes like motor control and visual identification to free up bandwidth for higher reasoning and complex thought. Geth can't share sensory data—they aren't a hive mind like the rachni —but in large groups they have more to think with. An individual geth has only a basic intelligence on par with animal instincts, but in groups they can reason, analyze situations, and make tactical decisions as well as any of the organic races.

An exception would appear to be Legiona geth specifically designed to operate as an autonomous sentient unit outside the Perseus Veil. Legion possesses over 11 times as many geth programs as a standard geth platform and can function intellectually on its own.

As all geth are networked to each other, they may communicate their exact thoughts and ideas at the speed of light. They find organic methods of communication, such as body language and spoken word, to be largely inefficient; the geth are able to communicate their thoughts flawlessly without any fear of misinterpretation. Because of this they have no true form of government and no system of rank.

When a matter must be decided upon, the geth communicate all viewpoints of a situation and a consensus is made, the decision being whatever benefits the geth as a whole the greatest. Eventually, they started asking the quarians questions only sentient beings would think to ask; in one notable instance, a domestic geth unit asked its owner if it had a soul.

Alarmed at this, the quarians decided it would be best to shut down all geth before they conceived of revolt. The attempt failed, and a war began between the geth and the quarians, which geth afterwards referred to as the Morning War. Unknown to the quarians themselves, the geth actually allowed them to leave; unsure of the repercussions of eradicating an entire species-namely their own creators- and having decided that the quarians were now too weak to be a threat, the geth decided to draw back their forces so that the surviving quarians could flee.

The fleet of quarian ships that escaped the Veil became known as the Migrant Fleet, and has been roaming the galaxy ever since. The geth continued development of new technology and variations of mobile platforms, separating their technology base from the rest of the galaxy.

They obtained an ultimate goal in this time period: to create a Dyson sphere -like object, which could house every single geth program. Approximately three centuries after the Morning War, the geth were approached by the Reaper Nazaraalso called Sovereign. It offered them technology that would aid them in achieving their goal, in exchange for their assistance in capturing the Citadel and letting the Reaper invasion begin. The majority of the geth dismissed the offer, deeming it better to accomplish their goal with their own technology rather than be dependent on another race's technology.

These geth discarded what they called the "superstitious title" of the Reapers, and simply called them the Old Machines. A small percentage of geth, however, accepted the Reaper's help. Henceforth these geth were referred to by the mainstream geth as "heretics". They were allowed to peacefully leave the main geth network, and aid Nazara and its turian agent, Saren Arterius.

The heretics came to revere Nazara as a god, the pinnacle of synthetic evolution. Unknown to them, Nazara was repulsed by the heretics' worship of it. The Reaper was actually insulted by their "pitiful devotions", though it recognised their value as tools to facilitate its goals.The current best source of documentation for Geth is geth.

An Ethereum network is a private network if the nodes are not connected to the main network. In this context private only means reserved or isolated, rather than protected or secure. The network ID is an integer number which isolates Ethereum peer-to-peer networks. Connections between blockchain nodes will occur only if both peers use the same genesis block and network ID.

Use the --networkid command line option to set the network ID used by geth. The main network has ID 1. If you supply your own custom network ID which is different than the main network, your nodes will not connect to other nodes and form a private network.

Ethash consensus, being a proof-of-work algorithm, is a system that allows open participation by anyone willing to dedicate resources to mining. While this is a great property to have for a public network, the overall security of the blockchain strictly depends on the total amount of resources used to secure it.

As such, proof-of-work is a poor choice for private networks with few miners. As more mining resources are deployed on the network, creating a new block becomes harder so that the average block time matches the target block time. The clique consenus protocol is specified in EIP The initial set of authorized signers is configured in the genesis block.

Signers can be authorized and de-authorized using a voting mechanism, thus allowing the set of signers to change while the blockchain operates. Every blockchain starts with the genesis block. When you run Geth with default settings for the first time, it commits the main net genesis to the database. For a private network, you usually want a different genesis block.

The genesis block is configured using the genesis. When creating a genesis block, you need to decide on a few initial parameters for your blockchain:.

This is an example of a genesis. Note that the initial signer set must be configured through the extradata field.
