In 2016 Community Ethereum had time to experience the excitement, to experience disappointment, split, solve technical problems and to meet with hostile actions. A new wave of enthusiasm with which Ethereum waiting for 2017, this time held back by caution, reasonable objections and a better understanding of reality.
In order to justify the hopes and expectations, has to be done a lot of work, because from the very beginning of the creators called the Ethereum "blokchain 2.0" - the platform of the new world. Ahead of the new challenges and competitors do not sleep.

Late last week, the markets calmed down, but waiting for the second hardfork add some nervousness. Hardfork First, fix the pricing of a number of opcodes was a success, although under tight time pressure. According to the latest information, updated versions of the core network clients (geth, parity, ethereumJ) are working properly, the network is in operation, although the consequences of recent attacks require a further technical hardfork.

Most people are interested in is not the particular detail, they just need to have their components and wallets quickly synchronized with the network and does not hang. They are important safety and need to arising problems were solved quickly. Now, when the situation is resolved, the community comes to the realization that hardforks are needed, and when the sky does not fall on the ground the emergence of new problems. There is a new question: What's next? Whither Ethereum, and what will be the next step?
                                                                                      
                     Proof of Stake


Main Event 2017 - this release Serenity Serenity - Ethereum Casper 2.0 protocol, providing for a transition from a consensus PoW to the distribution of shares (PoS).
The main objective of Ethereum project is to create a Distributed Computer World - a decentralized network of transactions managed by smart contracts.
Such an ambitious task requires a significant increase in network performance and speed of transactions is that PoW protocol unable to provide.

As a problem-at least, Ethereum Foundation has established the following guidelines in Casper:
Execution time unit: 4 seconds (the current average time - to 14.5);
Delay / finalization block: 8 seconds
Power Networks 100 000 transactions / sec (current capacity - 14 )


To provide the desired network capacity addition PoS, require another implementation technology - sharding. In its current form, the power of the entire Ethereum network is determined by the slowest node, since any operation is carried out by all nodes on the network. According sharding technology, instead of a single blokcheyna network consists of a plurality of parallel chains, each of which carried out some of the code.
According to the original road map Ethereum, by Casper had to be implemented in the second half of 2016, but these plans were not destined to come true: the collapse TheDAO and the events that followed it practically frozen for 2 months all promising development, and in addition, the development of the transition to PoS I met with a number of technical problems.
Release Serenity and Casper Protocol is scheduled for the summer of 2017, a more precise date yet.
                                           Prices and forecasts

Cost ether (ETH) in recent ranges in 10 - $ 12, which is somewhat disappointing, but taking into account all that has happened this year, it seems that the rate of ETH accurately reflects the current state of the network and the level of recognition of the business network. Volatility cryptocurrency is such that it is impossible to predict the course of conduct, even in the next few days, not to mention the 2017 year.

In general, members of the community choose to ignore Ethereum price dynamics ETH and instead focus on creating Dapps and invest in them, waiting to see what they themselves become sources of added value. However, if in a few months in 2017 capitalization Ethereum and will fluctuate within the 10% of Bitcoin, investors will doubt the market prospects of the technology, and to seek investment opportunities in other places.
                                            Breakthrough applications

Wanted "killer application." Unprecedented activity is observed in Dapps development sector - an impressive number of start-ups from around the world generating ideas and tries to implement them, to "make the world a better place." Availability programmable blokcheyna opened up a whole new world of opportunities in front of entrepreneurs and developers.
Already, the total capitalization of the applications that are based on Ethereum is more than 10% of the cost of the motherboard platform (Augur, Iconomi, Digix, SingularDTV), and many more on the way. It is no exaggeration to say that the potential of the Ethereum and smart contracts to improve the efficiency of existing business processes is considerable.
However, the business still expects "killer app," and the sooner it will manifest itself, the better. Of course, a good dose of external attention and an additional investor interest never over, especially after all the disappointments of 2016, but more importantly, because it is proof that smart contracts - this is not just an abstract concept, but a useful tool of the real world. And if such an application does not appear in the next 6 -12 months, it will cast doubt on the whole technology.
                                                                                  
                       Brand awareness and relationships with business
On this front fault almost to nothing. The number of accounts, the daily volume of transactions, the flow of investment, finally a community grow at a solid pace. For 16 months the Fund Ethereum done a great job. Conference of Devcon, partnerships with governments, regulators and banks, educational activities - all of this is done at the highest level. We should also mention the annual Hackathon Ether.Camp: even against the backdrop of disagreement about the ICO, this exemplary event to attract new forces in the developer community.
