Ethereum or bitcoin mining
If you don't feel comfortable securing your ether right now but just want to check that your presale wallet is included in the blockchain, then use our online balance checker. The Ethereum network is kept running by computers all over the world. In order to reward the computational costs of both processing the contracts and securing the network, there is a reward that is given to the computer that was able to create the latest block on the chain.
Every 15 seconds, on average, a new block is added to the blockchain with the latest transactions processed by the network and the computer that generated this block will be awarded 3 ether. Due to the nature of the algorithm for block generation, this process generating a proof of work is guaranteed to be random and rewards are given in proportion to the computational power of each machine.
If you are on a private network and if you just want to test the technology for free, you should then any normal computer with a normal CPU will be able to run the network and earn test ether ether that is only redeemable on the test network where it was generated through mining.
This is the best choice for small-scale network or testing privately, as it's less resource intensive. On the real or live test network a normal desktop or laptop computer might take a very long time to successfully mine a block and receive ether. Before you do any mining, you need to set which address will receive your earnings called "etherbase".
You only need to do this once. Here's how to set your etherbase and then start mining:. Its goal is to protect miners like yourself so that you will only ever need your home computer to remain competitive. The DAG should take about 10 minutes to generate and as soon as it finishes, Geth will start mining automatically.
If you are serious about mining on the live ethereum network and getting real ether rewards, then you should use a dedicated computer with very powerful graphics cards in order to run the network. If you are using Eth then GPU mining comes out of the box. There are currently two options for GPU mining in Geth available. You can read a more detailed description of how to install it on this mining post.
This is a version for the pro miners. Go experimental GPU branch. It's experimental so you need to build go from source to get it. This version is focused on hobbyists and developers. To install it, clone geth from source and then switch to the GPU Miner branch. You can read all about the theory behind this and its design in the Ethereum gitBook, mining chapter.
Note that for Serenity a future release, a major milestone on the Ethereum development roadmap we are planning to switch to Proof of Stake PoS. Mining prowess roughly scales proportionally to memory bandwidth.
Empirical evidence has already confirmed this, with R9 x regularly topping benchmarks. Don't expect to see them on the market, and if you do, proceed with extreme caution. Ethereum would never be possible without bitcoin—both the technology and the currency—and we see ourselves not as a competing currency but as complementary within the digital ecosystem.
Ether is to be treated as "crypto-fuel", a token whose purpose is to pay for computation, and is not intended to be used as or considered a currency, asset, share or anything else. If so desired one could trade bitcoins for ether with the purpose of executing contracts and trade it back immediately in order to keep their value pegged and secured by the bitcoin network.
The latest version of the wallet includes an automatic conversion between ether and bitcoin. Use a pegged derivative: Ethereum is a great tool for creating complex trading between multiple parties. If you have a source for the price of Bitcoin that all parties trust, then it's possible to create an ethereum based currency whose value is pegged to the market value of Bitcoin. This means that you could trade bitcoins to a token that is guaranteed to always trade back to the same amount of bitcoins while still being fully compatible with other ethereum contracts.
Use a Bitcoin relay to convert a 2-way peg: This means that you can use Bitcoin's native limited scripting capability to lock a bitcoin into a contract that is directly connected to an ethereum contract, which can then issue an ethereum based token that is guaranteed to be backed by bitcoin. The relay is under development and as implementations are tested and proved to be secure, we will list them here. Ethereum addresses don't have built-in checks on them yet.
That means that if you mistype an address, your ether will be lost forever, without a secondary confirmation window. If you are moving a significant amount, start with smaller quantities that you can afford to lose, until you feel comfortable enough. There are two types of accounts in Ethereum: In this section, we focus on the former. The remainder of this guide will be dedicated to the latter. Similarly, your transactions are also of two types: Before you execute your first ether transfer you need a friend to send your ether to.
Assuming you created a second account to send the ether to:. The first two lines set local variables with account numbers for easier access later. Change the sender and recipient addresses to whatever you like. The third line converts the chosen amount to the network's base unit wei. Although there are many names for ether denominations, we will use only two: Wei is the atomic unit of ether, and is the one used on the system level. They may also be a symptom of nodes deployed to skew node counts for various different implementations a.
The entire blockchain for both systems is determined by fewer than 20 mining entities . While traditional Byzantine quorum systems operate in a different model than Bitcoin and Ethereum, a Byzantine quorum system with 20 nodes would be more decentralized than Bitcoin or Ethereum with significantly fewer resource costs.
Of course, the design of a quorum protocol that provides open participation, while fairly selecting 20 nodes to sequence transactions, is non-trivial. Thus, we see that more research is needed in this area to develop permissionless consensus protocols that are also energy efficient.
Ethereum has a much higher uncle rate than Bitcoin's pruned block rate. This is by design, as Ethereum operates its network closer to its physical limits and achieves higher throughput. As a result, however, less of Ethereum's hash power goes towards sequencing transactions than Bitcoin's. Put another way, some hash power is wasted on uncles, which do not help carry out directly useful sequencing work on the chain. Relay networks ferry blocks quickly among miners and full nodes, and help reduce wasted effort by reducing uncle and orphan rates.
Fairness is an important metric: If a system is perfectly fair, there would be fewer reasons for miners to pool their resources into larger, cooperating pools that operate in unison. To measure fairness, we looked at the proportion of blocks that miners have on the main chain divided by the proportion of their blocks that did not help advance the blockchain, namely, pruned blocks and uncles. In an ideal system, this metric would be equal to 1. The level of fairness in both systems is, roughly speaking, comparable.
But there is a big difference in variance of fairness , with Bitcoin exhibiting high variance. That is to say, mining rewards are more unpredictable for smaller miners in Bitcoin. This is partly because the high block rate in Ethereum helps provide many more opportunities for the laws of large numbers to apply in Ethereum, while Bitcoin, with its infrequent blocks, can exhibit much more uncertainty from month to month.
The full details, of how we measured the data and what we found in more precise terms, are in our paper. Gencer is a researcher at LinkedIn. His thesis research focused on improving the scalability of blockchain technologies.

Ethereum is Better Distributed Than Bitcoin Compared to Ethereum, Bitcoin nodes tend to be more clustered together, both in terms of network latency as well as geographically.
In contrast, Ethereum nodes tend to be located on a wider variety of autonomous systems.
