Ethereum now processes 15 transactions per second, but that number is expected to change to 100,000.

Vitalik Buterin, Ethereum founder, in his interview with Abra CEO Bill Barhydt talked about issues his team is currently working on, focusing a lot on scalability.
“The Ethereum blockchain right now can process 15 transactions per second. Really, we need 100,000,” said Buterin.
He realises the goal will not be achieved overnight.
“There are two major kinds of strategies that we¡¯re working on for scalability. One is layer-one scaling and the other is layer-two scaling. Layer-one scaling basically means improving the blockchain protocol itself to process a larger set of transactions. And the main bottleneck with blockchains right now is basically every user has to download the whole blockchain. Which basically means the blockchain can¡¯t hold more transactions than one guy¡¯s computer can store.”
One of the tools that will dramatically improve transaction speed is ¡®sharding¡¯, which Ethereum has worked on for some time.
“§°ur solution, called sharding, basically means that you split up the different transactions to randomly selected, different groups of computers. And this basically means that the blockchain can process way more things than one single computer can hold. And that can increase scalability by maybe a factor of 1,000 or so, but then potentially even more, much later down the road,” added Buterin.
Ethereum developers are simultaneously trying to find other solutions to tackle scalability.
“The other kind of scaling that we are working on is layer-two scaling. Which basically means designing applications in such a way that not everything that happens actually goes on the blockchain. So basically, instead of going to the blockchain every single time any user does anything, you perform most of your operations off-chain using cryptographically signed messages. And you only need to put data onto the chain when there is some kind of dispute.
So there¡¯s two major classes of systems we¡¯re working on in this regard. One is called state channels. And there¡¯s a bunch of teams working on this. There¡¯s a team called L4 in Toronto that¡¯s done some really good work. And another project is Plasma. And there¡¯s a lot of work that¡¯s been done on that. OmiseGo is this decentralized exchange that¡¯s building on plasma. There¡¯s TheMatter. There¡¯s more and more of these projects. And then, there¡¯s one of our researchers, Karl Floersch, who has been working on implementation of a reasonably complete Plasma prime specification, which is the latest version of Plasma ¨C which has some really cool features in terms of increasing scalability and reducing the amount of data you have to store.”
Vitalik also underlined two other essential challenges ¨C privacy and ¡®usability of security¡¯.
“The other big challenge that I care about is usability of security. So coming up with easy-to-use ways for people to store their private keys that don¡¯t become vulnerable to someone just losing everything because they lost their private key or their private key got stolen. And there are some interesting solutions that are coming out for that. But it will still take a couple of years for all these different strands to get somewhere.”
Ethereum network has recently been upgraded. Developing on Ethereum is now more cost-effective after adding Bitwise shifting instructions, making it slightly cheaper to conduct certain functions on the chain. Some coding operations were simplified, while smart-contract development got more seamless.
So far our investigation has been analytical. We have seen Plotinus acquire, one after another, the elements out of which his system has still to be constructed. The first step was to separate spirit from matter. They are respectively distinguished as principles of union and of division. The bodies given to us in experience are a combination of the two, a dispersion of form over an infinitely extended, infinitely divisible, infinitely changeful substratum. Our own souls, which at first seemed so absolutely self-identical, present, on examination, a similarly composite character. A fresh analysis results in the separation of Nous or Reason from the lower functions of conscious life. And we infer by analogy that the soul in Nature bears the same relation to a transcendent objective Nous. Nous is essentially pure self-consciousness, and from this self-consciousness the world of Ideas is developed. Properly speaking, Ideas are the sole reality: sensible forms are an image of them impressed on matter through the agency of the world-soul. But Nous, or the totality of Ideas, though high, is not the highest. All that has hitherto occupied us, Nature, Soul, and Reason, is316 pervaded by a fundamental unity, without which nothing could exist. But Soul is not herself this unity, nor is Reason. Self-consciousness, even in its purest expression, involves a duality of object and subject. The notion of Being is distinct from the notion of oneness. The principle represented by the latter, as the cause of all things, must itself transcend existence. At the same time, it is revealed to us by the fact of our own personal identity. To be united with oneself is to be united with the One. ¡°What?¡± She was strong, slender as she was, and she freed herself almost without effort. And yet he would not be warned. "Don't you love me?" he insisted, as though she had not already made it plain enough. "Don't be cross, Maria," pleaded Annabel. "I didn't know nothin' of it. You know I've been down to see the Robinses, and intended to stay till tomorrer, but something moved me to come home today, and I just happened to take this train. I really didn't know. Yet," and the instinctive rights of her womanhood and her future relations with Si asserted themselves to her own wonderment, "I had what the preachers call an inward promptin', which I felt it my dooty to obey, and I now think it came from God. You know I ought to be with Si as soon as anybody," and she hid her face in her hands in maidenly confusion. trouble. Send down a detail at once for Shorty Elliott, Co. Wilson's first instructions were as to Shorty's personal appearance. He must get a clean shave and a hair-cut, a necktie, box of paper collars, a pair of white gloves, have blouse neatly brushed and buttoned to his throat and his shoes polished. As soon as he saw that he was likely to remain at Headquarters for some time. Shorty became anxious about that letter from Sammy, and after much scheming and planning, he at last bethought himself of the expedient of having the Chief Clerk write an official letter to Sam Elkins, the postmaster and operator at Bean Blossom Creek Station, directing him to forward to Headquarters any communications addressed to Corp'l Elliott, 200th Ind. Vols., and keep this matter a military secret. "Well, I have stirred up a yaller-jacket's nest for sure," thought Shorty, rather tickled at the odds which were arrayed against him. "But I believe I kin handle 'em until either the train pulls out or the boys hear the ruction and come to my help." She felt that he would come¡ªhe would return to her in the reaction that swung him from Rose. But would she be able to keep him? She did not feel so sure of that¡ªfor that did not depend on her or on him, but on that mysterious force outside themselves with which they had both already struggled in vain. It was only lately that her longing for love and freedom had become a torment. Up till a year or two ago her desires had been merely wistful. Now a restless hunger gnawed at her heart, setting her continually searching after change and brightness. She had come to hate her household duties and the care of the little boys. She wanted to dance¡ªdance¡ªdance¡ªto dance at fairs and balls, to wear pretty clothes, and be admired and courted. Why should she not have these things? She was not so ugly as many girls who had them. It was cruel that she should never have been allowed to know a man, never allowed to enjoy herself or have her fling. Even the sons of the neighbouring farmers had been kept away from her¡ªby her father, greedy for her work. Tilly, by a lucky chance, had found a man, but lucky chances never came to Caro. She saw herself living out her life as a household drudge, dying an old maid, all coarsened by uncongenial work, all starved of love, all sick of, yet still hungry for, life. "And is this your present?¡ªWhat is your name?" "But, take care," said Margaret, "that you say not whom it is for." But Margaret was many minutes ere she could do more than kiss his hand, and wet it with her tears. At length, when her emotions of joy and surprise had in some degree subsided, she replied, that Holgrave was still living a villein at Sudley. HoMExiao77av
