Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

ASKfm Reaches New Peak, Scales Everest

0


As everyone knows, Bitcoin has had an ultra-impressive run. Now, initial coin offerings (ICOs) are the cryptocurrency space’s hottest offerings, thanks to their ability to provide high returns on investment. Having said that, not all ICOs are created equal. Some will barely reach the finish line, let alone shoot the moon. With investors always looking for “the next Bitcoin,” the race to take the next big ICO to the moon is already underway! 
The Highest Token in the World (Literally)
Recently, four mountaineering enthusiasts embarked on a tremendous challenge to scale the world’s highest peak, Mount Everest, which stands gigantic at 8,848 meters above sea level. Only 4,833 people have ever made it to the summit, while another 288 have tragically succumbed in the attempt.
As part of the project and expedition, the team raised the ICO flag and two Ledgers, to which ASKfm tokens (ASKT) are credited. This act makes it possible to honestly state that the ASKT is able to conquer new peaks, being literally the “highest token in the world and the “closest to the moon.”
Out of the four mountaineers in the 2018 expedition, two members: Ira Galai (an honoree …

multi sig transactions – Electrum 2of2 multisig both cosigners share the same priv key

0


I set up this wallet on the same machine online. Thinking that was it, it was only until i sent funds to this wallet and tried to spend them that i could only partially sign the transaction.

I opened up the wallet file in notepad and indeed, the 2x cosigner had no info there apart from null to priv key and the public cosigner key.

Ive tried most things ive read but i cant get at them funds. Can anyone help?

i noticed there was never 1 of 2 wallets, both wallets were both 2/2 multisig.
I have the passwords, seed and everything including the private key that both public keys are attatched to but i dont know how to get my funds or disable or fix the coding.

thanks

Blockchain Micro-Learning Platform to Help Students Earn as They Learn

0


A new blockchain platform by an established company in the educational sector is going to enable users to earn crypto tokens as they learn – all the while making lessons exciting and ensuring billions of people around the world have access to talented instructors.

Code of Talent’s team say they want to address multiple failings in the industry which have seen learners become disengaged in boring, generic and uninteractive classrooms. This also has huge ramifications for students attempting to enter the world of work or those seeking to change careers, as a disconnect between the theory they have learned and the skills they desperately need affects their employability and leaves employers struggling to fill vacant positions for skilled jobs.

The company argues that even e-learning platforms – which use the internet to connect with students from around the world – are unable to address the inherent issues facing this important sector. This is because the content in their courses is rarely personalized and lacks human interaction from a real-life educator, resulting in “dramatic lows in terms of course completion.” According to HarvardX and MITx, only 5.5 percent people who enrolled in one of their open online courses actually completed the classes.

Micro-learning: A powerful method?

According to Code of Talent, micro-learning is the solution that instructors, learners and employers deserve. This technique involves daily learning sessions which are 10 minutes in length, in a virtual environment where there is a maximum of 40 participants per educator (also known as a “content provider.”)

In its white paper, the company claims that micro-learning can increase the speed of a student’s development by up to 300 percent – with costs also tumbling by 50 percent. This is partially because learning in chunks of between three and seven minutes better reflects the brain’s working memory and attention span.

Code of Talent’s product has already been successfully finalized, with executives claiming it has experienced “great adoption from paying customers” such as Pfizer, Astra Zeneca, Societe General, JTI and more.

Exciting key features for learners include the ability to engage in sessions from any device – with milestones, levels, missions, points and badges gamifying their experience and making it easy for them to track their progress in real time. They can also receive instant notifications within the platform or directly to their email.

Meanwhile, instructors also benefit from an “easy and intuitive” interface which gives them the flexibility they need when designing training sessions. They can easily evaluate the progress of their participants and offer rewards or feedback, plus use video streaming in real time or on special occasions. Educators also receive a share of the token pool which has been set aside to incentivize the ecosystem’s users – and instructors who deliver the most popular and engaging lessons will be given the chance to gain Premium Content Provider status. From here, the level of their incentives will increase, and they will get the chance to charge tokens for their premium courses.

Built by an established company

Code of Talent is the brainchild of Ascendis, which has 21 years’ experience in this sector. According to the start-up’s white paper, Ascendis currently serves 550 corporate customers and 45,000 face-to-face learners on an annual basis – resulting in a turnover of €7 mln in 2017. Its latest B2B product has been developed in conjunction with Co-Factor, described as an industry awarded expert in digital engagement. Code of Talent has also established a strategic partnership with Ideologiq, a European digital innovation agency.

The start-up’s token generation event is scheduled to begin on July 9 – and by the end of the year, it aims to have opened officers in Russia, the US, India, Africa and Latin America. The first version of the Code of Talent blockchain micro-learning platform is scheduled to launch at the start of 2019, and the company hopes to attract 300,000 learners, 2,000 active educators and 2,000 micro-learning courses by the second quarter of 2020.

How can miner avoid stale and orphan block?

If miner needs to minimize its cost, they need to make sure that they do not mine stale block or their mining block end up being orphan block?
How can a miner avoid it?

As messy as SegWit activation was, it is actually one of most decentralized ways to activate something. Miners didnt force it through, devs didnt either and niether did social media or node operators. Everyone sort of got a say. : Bitcoin

Singapore Proposes Regulatory Changes Which Could Green-Light Blockchain Related Exchanges

0


The Monetary Authority of Singapore (MAS) has proposed changes to its current regulations which are expected to lower the market entry for blockchain related exchanges.
A Regulator Responds to Blockchain & a Changing Financial Landscape
According to reports, MAS  – which is Singapore’s central bank and financial regulator – has issued a consultation paper in which it is reviewing the current regulatory framework which has been in place since 2002. This is to accommodate the demands of a dynamic financial services landscape. All financial institutions and other interested parties have been invited to submit written comments to the paper by 22 June 2018.
The authority has stated that the current regulatory framework cannot handle the demands of new business models that rely on emerging technologies.
One of these changes is blockchain technology and its related services, referenced in the consultation paper as  “new business models in trading platforms, including trading facilities that make use of blockchain technology, or platforms that allow peer-to-peer trading without the involvement of intermediaries”.

An Accommodation of New, Smaller Operators
The primary change proposed by MAS in its consultation paper is the move to a three-tier system for its second …
