Driven by the quest for eternal youth, humankind has spent centuries obsessed with the question of how it is exactly that we age. With advancements in molecular genetic methods in recent decades, the search for the genes involved in the aging process has greatly accelerated. Until now, this was mostly limited to genes of individual model organisms such as the C. However, researchers have long assumed that such genes arose in the course of evolution and in all living beings whose cells have a preserved a nucleus — from yeast to humans. Researchers at ETH Zurich and the JenAge consortium from Jena have now systematically gone through the genomes of three different organisms in search of the genes associated with the aging process that are present in all three species — and thus derived from the genes of a common ancestor. Although they are found in different organisms, these so-called orthologous genes are closely related to each other, and they are all found in humans, too. In order to detect these genes, the researchers examined around 40, genes in the nematode C.

However, there are a few differences, and they stem in part from the fundamental differences between Bitcoin and Ethereum. In the most abstract sense, Bitcoin and Ethereum are cousins; they both have “blocks” of transactions linked together into a chain, they both use Proof of Work to reach consensus for now, as Ethereum plans to move to Proof of Stake in a future release , they are both about decentralizing trust. But that’s where the similarities end.
Here are just some of Ethereum’s differences:. In a nutshell, Bitcoin is about decentralized, trust-minimizing, sound money. Ethereum is about decentralized, trust-minimizing, sound computation. Much more detail about these differences can be read at the Ethereum Wiki here.
The Mystery Behind Block Time
Scalability is one of the major points of concern of the Ethereum blockchain. The current limitations faced by the network in terms of capacity and speed prevents it from being adopted on a larger global scale. The concept was born in August of as a scaling solution technique for the Ethereum blockchain. Along with Thaddeus Dryja, Joseph Poon was also responsible for the conception of the Lightning Network , which is a scaling solution proposed for Bitcoin in
Originally released in , Ethereum has had developers working through three major for future improvements, including that for improved transaction speed. Its original release date was set for November of
Ethereum is a cryptocurrency platform that pioneered the concept of smart contracts. This has led it to be the foundation for numerous other cryptocurrencies and to a long, complex development and deployment. Bitcoin was developed to achieve one goal: create a decentralized alternative to the existing financial industry. The creator of Ethereum, Vitalik Buterin, saw the potential for using the blockchain for other things and pushed for a scripting language for Bitcoin to make development of applications on the blockchain possible but his proposal was rejected.
In late , he proposed the development of a new platform with support for more generalized scripting and application development. The Ethereum whitepaper describing the proposed technology was published by Buterin in November In January , the beginning of the development of the Ethereum platform was publicly announced. The non-profit Ethereum Foundation was founded in June to support development of the Ethereum cryptocurrency platform. To create the Ethereum Network, the Ethereum team needed development funding.
Rather than go to venture capitalists, they decided to reach out to the cryptocurrency community in a crowdsale. The Ethereum crowdsale ran in July and August and allowed future users and investors to purchase Ether tokens on the future Ethereum blockchain in exchange for Bitcoin. Since Bitcoin was an established currency at the time, the Ethereum team could trade it in for fiat currency to cover development costs. As a result of the Ethereum crowdsale,
An exploratory study of smart contracts in the Ethereum blockchain platform
Ethereum is a blockchain platform that supports smart contracts. Smart contracts are pieces of code that perform general-purpose computations. In this paper, we conduct an exploratory study of smart contracts. Differently from prior studies that focused on particular aspects of a subset of smart contracts, our goal is to have a broader understanding of all contracts that are currently deployed in Ethereum.
In particular, we elucidate how frequently used the contracts are activity level , what they do category , and how complex they are source code complexity. Our study period runs from July inception of Ethereum until September

Many people are familiar with blockchain technology, but did you know that Ethereum has the largest and most active blockchain community in the world? Unlike many other blockchain networks, Ethereum is programmable. This customizable feature has enabled developers to solve problems ranging from digital identification and privacy, to corporate ownership and data security. When the blockchain community disagrees on what changes the network needs to function smoothly or when such changes should take place, developers plan for a fork an offshoot of the underlying code rules.
It also includes details on the highly anticipated Istanbul hard fork, planned for December Forks are common practice in the software industry, and happen for one of two reasons: split opinions within the community, and required changes to the blockchain code. Below are some of the most prominent and important forks—both hard and soft—on the Ethereum blockchain since its launch.
Vitalik Buterin, founder of Ethereum, and his team finished the 9th and final proof of concept known as Olympic in May The Ethereum blockchain, also known as Frontier, went live shortly after, on July 30, This rollout included three critical updates to Ethereum: the removal of centralization on the network, enabling users to hold and transact with ETH, and to write and deploy smart contracts. Widely regarded as the only Ethereum fork of any significance, this hard fork was based on the controversial DAO event.
The original chain became known as Ethereum Classic, and the new chain moved forward as the main Ethereum chain.
Vitalik Buterin Says Much-Delayed Ethereum 2.0 Still on Track for July Launch
Ethereum Classic is an open source , blockchain -based distributed computing platform featuring smart contract scripting functionality. Ethereum Classic maintains the original, unaltered history of the Ethereum network. However, due to a hack of a third-party project, the Ethereum Foundation created a new version of the Ethereum mainnet on 20 July with an irregular state change implemented that erased The DAO theft from the Ethereum blockchain history.
Ethereum Classic’s native Ether token is a cryptocurrency traded on digital currency exchanges under the ticker symbol ETC. Implemented on 11 December , the current ETC monetary policy seeks the same goals as bitcoin of being mechanical, algorithmic, and capped. ETC can be exchanged for network transaction fees or other assets, commodities, currencies, products, and services.

High-quality materials are critical for advances in plasmonics, especially as researchers now investigate quantum effects at the limit of single surface plasmons or exploit ultraviolet- or CMOS-compatible metals such as aluminum or copper. Unfortunately, due to inexperience with deposition methods, many plasmonics researchers deposit metals under the wrong conditions, severely limiting performance unnecessarily.
This is then compounded as others follow their published procedures. In this perspective, we describe simple rules collected from the surface-science literature that allow high-quality plasmonic films of aluminum, copper, gold, and silver to be easily deposited with commonly available equipment a thermal evaporator. Recipes are also provided so that films with optimal optical properties can be routinely obtained.
ETH 2.0 / Serenity Roadmap Explained
We have a very large development team working with very advanced and often quite complex new technology, and keeping everybody up to date on that simultaneously is going to be tricky. I have a lot to wrap my head around. I was a 3D graphics programmer through the s, and have a reasonably strong grounding in financial cryptography I was, and I am not ashamed to admit it, a cypherpunk in those days. There will be another blog post with much more detail about the release schedule for the first live Ethereum network shortly – likely by the end of this week, as the developer meeting that Gav mentions in his post winds up and the conclusions are communicated.

The Ethereum Network is currently at a cusp of seismic proportions. Originally released in , Ethereum has had developers working through three major upgrades thus far to create the massive decentralized world computer that it is today. Now, with the upcoming ETH 2. Ethereum is a programmable blockchain that represents the infrastructure for Web3.
This new kind of internet improves upon the world wide web as we know it today. The infrastructure is defined by the Ethereum platform, which allows any software developer to create decentralized tools and apps on the open, public blockchain. All the users across the globe are connected to the EVM via their computers. Each computer, or node, runs the Ethereum software while storing a real-time copy of the blockchain. When a transaction is recorded on the blockchain, every user has that information.
Ethereum, in this way, is decentralized with no single point of failure. The Ethereum Virtual Machine is distributed, making up a global, peer to peer network. The ETH 2. The Ethereum Blockchain has its own native cryptocurrency named Ether, or ETH , which has long been the number two cryptocurrency, behind bitcoin, in terms of total market cap and the size of the blockchain.
