In a consortium blockchain, the consensus process is controlled by a pre-selected group – a group of corporations, for example. The right to read the blockchain and submit transactions to it may be public or restricted to participants. Consortium blockchains are considered to be “permissioned blockchains” and are best suited for use in business.
Semi-private blockchains are run by a single company that grants access to any user who satisfies pre-established criteria. Although not truly decentralized, this type of permissioned blockchain is appealing for business-to-business use cases and government applications.
Private blockchains are controlled by a single organization that determines who can read it, submit transactions to it, and participate in the consensus process. Since they are 100% centralized, private blockchains are useful as sandbox environments, but not for actual production.
Anyone can read a public blockchain, send transactions to it, or participate in the consensus process. They are considered to be “permissionless.” Every transaction is public, and users can remain anonymous. Bitcoin and Ethereum are prominent examples of public blockchains.
The Stanford Women in Data Science conference (WiDS) is a one day global conference that will bring data scientists together to share cutting edge research. The conference aim is to inspire and encourage data scientists worldwide and exclusively support women in the field.
We will proudly host WiDS at The Alan Turing Institute. The conference will feature eminent female speakers through technical talks, lunchtime discussions on data science (topics to be announced shortly), a panel discussion and networking event.
The conference programme and speaker information will be soon available through the conference website. The event will be available worldwide via live streaming and the conference talks will be broadcast online.
The event will provide great opportunities to connect with potential mentors, collaborators and peers; hear about recent advancements in data science and explore new research dimensions.

We welcome all regardless of gender to join us on Friday 6 April 2018 for an excellent learning experience.
n a 2016 survey of higher education institutions (study published by UPCEA and Pearson), one in five institutions now offer the opportunity to earn verified digital badges.
The way we learn is continuously evolving. In the coming years we should expect to see organizations of all kinds start experimenting with the increasing number of badge platforms out there. While Mozilla Open Badges seems to be leading the way in the development of badging, other networks including Badge Alliance, Credly and Digital Me are growing their networks as they launch their own competing platforms. Students and professionals use social networks and other digital platforms daily, and with that comes a different way to showcase professional skills.
When we teach through modelling behaviour, the learner is in control, whereas teaching by shaping behaviour means the teacher is in control. In Western society, shaping has been the dominant mode for a very long time. But in other societies, it has not been the norm. For instance, Dr. Clare Brant was the first Aboriginal psychiatrist in Canada and a professor of Psychiatry at University of Western Ontario. In 1982 he presented Mi’kmaq Ethics & Principles, which included an examination of the differences in teaching between native and non-native cultures.
quality of opportunity has produced a new meritocratic aristocracy that has all the aloofness of the old aristocracy with none of its sense of noblesse oblige. Democracy has degenerated into a theatre of the absurd. And technological advances are reducing ever more areas of work into meaningless drudgery
Mr Deneen’s fixation on the essence of liberalism leads to the second big problem of his book: his failure to recognise liberalism’s ability to reform itself and address its internal problems. The late 19th century saw America suffering from many of the problems that are reappearing today, including the creation of a business aristocracy, the rise of vast companies, the corruption of politics and the sense that society was dividing into winners and losers. But a wide variety of reformers, working within the liberal tradition, tackled these problems head on. Theodore Roosevelt took on the trusts. Progressives cleaned up government corruption. University reformers modernised academic syllabuses and built ladders of opportunity. Rather than dying, liberalism reformed itself.
a 2017 survey of 11,500 girls across 12 European countries commissioned by Microsoft found 60% of respondents said they would feel more confident pursuing a STEM career if they thought men and women were being treated equally in those fields.
To increase access to the field and broaden the pipeline, institutions can ratchet up their STEM game by teaming up with K-12 and industry partners,
Here’s a quick rundown of the factors contributing to the carnage:
1). South Korea
Seoul has said that the government intends to crack down on the trading of cryptoassets. Officials have also floated the idea of taxes on crypto trading and other measures to tighten its grip on market considered by some as supporting money laundering and dangerous speculative investing. By some measures, South Korea represents about a fifth of the virtual-trade volume.
Russian President Vladimir Putin said on Tuesday that more oversight of cryptocurrencies may be needed “This is the prerogative of the Central Bank at present and the Central Bank has sufficient authority so far. However, in broad terms, legislative regulation will be definitely required in future,” he said, according to Russian news agency TASS.
The cyber currency known as Bitconnect, which has long drawn a critical eye from cryptocurrency investors because of its use of loans and the manner in which it solicits new investors, shut down. Bitconnect also promised a return of a quarter of a percentage point daily.
5). Bitcoin futures
Futures for bitcoin on exchange platforms are set to expire this month.
