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 Although Plasma and Lightning Network were both proposed as scaling solutions for blockchains, each has its own mechanisms and particularities. This article will briefly introduce the Ethereum Plasma, but keep in mind that Plasma alone is not a project, it is an off-chain scaling technique, or a framework for building scalable applications, which can be implemented in distinct ways by different research groups or companies. The main idea of the Ethereum Plasma is to establish a framework of secondary chains that will communicate and interact as sparingly as possible with the main chain in this case, the Ethereum blockchain. Such a framework is being designed to operate as a blockchain tree, which is hierarchically arranged in a way that numerous smaller chains can be created on top of the main one. These smaller chains are also referred to as Plasma chains or child chains. Note that sidechains and Plasma chains are similar, but not the same thing.

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.

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.
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.

The brains of more intelligent people are capable of solving tasks more efficiently, which is why these people have superior cognitive faculties, or as Elsbeth Stern, Professor for Research on Learning and Instruction at ETH Zurich, puts it: “when a more and a less intelligent person are given the same task, the more intelligent person requires less cortical activation to solve the task. While working on her doctoral thesis in Stern’s work group, Daniela Nussbaumer also found evidence of this effect for the first time in a group of people possessing above-average intelligence for tasks involving what is referred to as working memory.
Past studies conducted to identify the effect of neural efficiency have generally used groups of people that exhibit extreme variations in intelligence. Psychologists define working intelligence as a person’s ability to associate memories with new information as well as to adapt to changing objectives by filtering out information that has become irrelevant. The frontal lobe plays a pivotal role in these processes.
In order to test these abilities, the ETH researchers asked 80 student volunteers to solve tasks of varying complexity on a computer. One task, for example, was to determine whether individual letters or faces were part of a selection of letters or faces that had been shown to the subjects immediately beforehand. An especially difficult task involved identifying letters and faces shown to the subjects during past runs of the test within a time limit.
While the students were completing the tests, the researchers used electroencephalography EEG to measure their brain activity. For the results analysis, the researchers had the subjects take a conventional IQ test and then split them into two groups: one with slightly above-average IQs and another with well above-average IQs. The researchers found no differences in brain activity in either group of subjects when they performed very easy or very difficult tasks.
They did, however, see clear differences in the case of moderately difficult tasks. Stern attributes this to the fact that none of the subjects had any trouble whatsoever with the simple tasks and that the difficult tasks were cognitively demanding even for the highly intelligent subjects. In contrast, all subjects succeeded in solving the moderately difficult tasks, but the highly intelligent subjects required fewer resources to do so.
Block time defines the time it takes to mine a block. Both in bitcoin blockchain and ethereum blockchain, there is an expected block time, and an average block time. In bitcoin, the expected block time is 10 minutes, while in ethereum it is between 10 to 19 seconds. Both bitcoin and ethereum, at the time of this writing use a proof of work based distributed consensus algorithm ethereum is planned to move to a proof of stake based algorithm with its serenity release.

Read his full statement here. Vitalik Buterin said the Ethereum 2. Sometimes known as Serenity, Ethereum 2. Although originally slated for January , it was pushed back to Q2, and then again to Q3 July has been a target date for developers since the beginning of the year. At Consensus: Distributed, Buterin also said many Ethereum developer teams were busy working on a series of scaling initiatives that could be implemented soon after PoS had successfully launched.
These include well-known techniques like sharding, which effectively divides consensus into small groups to speed up verification times, as well as new scaling solutions currently in testing. Speaking at Consensus: Distributed earlier on Monday, Ethereum co-founder and former CTO Gavin Wood, who is now the founder of Parity Technologies, criticized his former project for its poor governance structure, which he said makes it next to impossible for Ethereum to act on behalf of the stakeholder community.

Ethereum ETH , also known as Ether, was first proposed in as an alteration to the then dominant Bitcoin BTC so that developers could create decentralized applications based on the underlying blockchain. The Ethereum platform and digital currency ETH were developed independently and deployed in While the coin has experienced notable volatility, the value of Ethereum has risen steadily making it one of the top cryptocurrencies by market cap.
Ethereum can be traded as an independent cryptocurrency, but its main purpose is to pay for transaction fees that take place on the network. The network is designed to facilitate smart contracts, which are a system for the verification of multi-stage and procedure-driven interactions between consenting parties. Ethereum boats a large number of decentralized applications based on its blockchain, including some developed by major software corporations.

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. By screening them, the scientists wanted to determine which genes are regulated in an identical manner in all three organisms in each comparable aging stage — young, mature and old; i. As a measure of gene activity, the researchers measured the amount of messenger RNA mRNA molecules found in the cells of these animals. When there are many copies of an mRNA of a specific gene, it is very active; the gene is upregulated.
Out of this volume of information, the researchers used statistical models to establish an intersection of genes that were regulated in the same manner in the worms, fish and mice. This showed that the three organisms have only 30 genes in common that significantly influence the aging process. By conducting experiments in which the mRNA of the corresponding genes were selectively blocked, the researchers pinpointed their effect on the aging process in nematodes.
