Es gab eine Zeit, in der Ethereum (ETH) und andere Kryptowährungen als eine Art Lottoschein angesehen wurden, allerdings haben sie sich mittlerweile als.
Smart contracts are high-level programming abstractions that are compiled down to EVM bytecode and deployed to the Ethereum blockchain for execution.
There is also a research-oriented language under development called Viper a strongly-typed Python -derived decidable language. Smart contracts can be public, which opens up the possibility to prove functionality, e.
One issue related to using smart contracts on a public blockchain is that bugs, including security holes, are visible to all but cannot be fixed quickly.
There is ongoing research on how to use formal verification to express and prove non-trivial properties. A Microsoft Research report noted that writing solid smart contracts can be extremely difficult in practice, using The DAO hack to illustrate this problem.
The report discussed tools that Microsoft had developed for verifying contracts, and noted that a large-scale analysis of published contracts is likely to uncover widespread vulnerabilities.
The report also stated that it is possible to verify the equivalence of a Solidity program and the EVM code. Ethereum is written in Turing complete language, which includes seven different programming languages.
Ethereum blockchain applications are usually referred to as DApps decentralized application , since they are based on the decentralized Ethereum Virtual Machine, and its smart contracts.
As of January , there are more than live DApps, with hundreds more under development. Some application examples include: Ethereum-based customized software and networks, independent from the public Ethereum chain, are being tested by enterprise software companies.
Ethereum-based permissioned blockchain variants are used and being investigated for various projects. In Ethereum all smart contracts are stored publicly on every node of the blockchain, which has costs.
The downside is that performance issues arise in that every node is calculating all the smart contracts in real time, resulting in lower speeds.
The Ethereum network has at times faced congestion problems, for example, congestion occurred during late in relation to Cryptokitties.
Izabella Kaminska, the editor of FT Alphaville , has pointed out that criminals are using Ethereum to run Ponzi schemes and other forms of investment fraud.

Rules No inappropriate behavior. Such a lack of interest could impact the development of the Ethereum Platform and potential uses of ETH.
It cannot predict the success of its own development efforts or the efforts of other third parties.
The User recognizes that the Ethereum Platform is under development and may undergo significant changes before release. The User acknowledges that any expectations regarding the form and functionality of the Ethereum Platform held by the User may not be met upon release of the Ethereum Platform, for any number of reasons including a change in the design and implementation plans and execution of the implementation of the Ethereum Platform.
The Ethereum Platform rests on open-source software, and there is a risk that the Ethereum Stiftung or the Ethereum Team, or other third parties not directly affiliated with the Stiftung Ethereum, may introduce weaknesses or bugs into the core infrastructural elements of the Ethereum Platform causing the system to lose ETH stored in one or more User accounts or other accounts or lose sums of other valued tokens issued on the Ethereum Platform.
Cryptography is an art, not a science. And the state of the art can advance over time. Advances in code cracking, or technical advances such as the development of quantum computers, could present risks to cryptocurrencies and the Ethereum Platform, which could result in the theft or loss of ETH.
To the extent possible, Stiftung Ethereum intends to update the protocol underlying the Ethereum Platform to account for any advances in cryptography and to incorporate additional security measures, but it cannot predict the future of cryptography or guarantee that any security updates will be made in a timely or successful manner.
As with other cryptocurrencies, the blockchain used for the Ethereum Platform is susceptible to mining attacks, including but not limited to:.
Any successful attacks present a risk to the Ethereum Platform, expected proper execution and sequencing of ETH transactions, and expected proper execution and sequencing of contract computations.
Despite the efforts of the Ethereum Stiftung and Team, known or novel mining attacks may be successful. Under such a scenario, the entire Ethereum Platform could become destabilized, due to the increased cost of running distributed applications.
Instability in the demand of for ETH may lead to a negative change of the economical parameters of an Ethereum based business which could result in the business being unable to continue to operate economically or to cease operation.
If the Ethereum Platform is rapidly adopted, the demand for transaction processing and distributed application computations could rise dramatically and at a pace that exceeds the rate with which ETH miners can bring online additional mining power.
Insufficiency of computational resources and an associated rise in the price of ETH could result in businesses being unable to acquire scarce computational resources to run their distributed applications.
This would represent revenue losses to businesses or worst case, cause businesses to cease operations because such operations have become uneconomical due to distortions in the crypto-economy.
We recommend any groups handling large or important transactions to maintain a voluntary 24 hour waiting period on any ether deposited.
In case the integrity of the network is at risk due to issues in the clients, we will endeavor to publish patches in a timely fashion to address the issues.
We will endeavour to provide solutions within the voluntary 24 hour waiting period. All disputes or claims arising out of, relating to, or in connection with the Terms, the breach thereof, or use of the Ethereum Platform shall be finally settled under the Rules of Arbitration of the International Chamber of Commerce by one or more arbitrators appointed in accordance with said Rules.
All claims between the parties relating to these Terms that are capable of being resolved by arbitration, whether sounding in contract, tort, or otherwise, shall be submitted to ICC arbitration.
Prior to commencing arbitration, the parties have a duty to negotiate in good faith and attempt to resolve their dispute in a manner other than by submission to ICC arbitration.
The arbitration panel shall consist of one arbitrator only, unless the ICC Court of Arbitration determines that the dispute is such as to warrant three arbitrators.
If the Court determines that one arbitrator is sufficient, then such arbitrator shall be Swiss resident. All nominations must be Swiss resident.
If a party fails to nominate an arbitrator, the Court will do so. The Court shall also appoint the chairman.
