Decentralized finance is built on blockchain technology, an immutable system that organizes data into blocks that are chained together and stored in hundreds of thousands of nodes or computers belonging to other members of the network.

These nodes communicate with one another (peer-to-peer), exchanging information to ensure that they’re all up-to-date and validating transactions, usually through proof-of-work or proof-of-stake. The first term is used when a member of the network is required to solve an arbitrary mathematical puzzle to add a block to the blockchain, while proof-of-stake is when users set aside some cryptocurrency as collateral, giving them a chance to be selected at random as a validator.

To encourage people to help keep the system running, those who are selected to be validators are given cryptocurrency as a reward for verifying transactions. This process is popularly known as mining and has not only helped remove central entities like banks from the equation, but it also has allowed DeFi to open more opportunities. In traditional finance, are only offered to large organizations, for members of the network to make a profit. And by using network validators, DeFi has also been able to cut down the costs that intermediaries charge so that management fees don’t eat away a significant part of investors’ returns.

Lately, there’s been no shortage of talk about the transition to Web3, a new digital frontier powered by blockchain and accessible via decentralized applications (dapps). But while many of the products created thus far are groundbreaking — offering verifiable digital ownership and access to new financial instruments — they still haven’t managed to galvanize mainstream adoption yet.

To reach critical mass, the blockchain industry needs to ensure that platforms and services are easy to use as their current-gen counterparts. ## **We aren’t there yet**

The current landscape of the internet is still very much grounded in Web2 architecture. While users can access a range of services, each requires its own unique username and password and third-party platforms are typically still needed to process payments. While this model has ostensibly worked well enough for the past two decades, it’s been mired by the centralized control of big tech companies, which thrive on selling user data.

GE is ready to rock the world of onshore wind turbines with 3D printing for a new concrete base.

Vast swaths of the US have yet to be tapped for wind energy, partly on account of politics and partly because wind speeds in those areas are less than optimal. Only the voting public can take care of the political end. Meanwhile, engineers and innovators are hammering away at the wind speed issue, which can be solved by building taller wind turbine towers. That’s not as easy as it sounds, but GE Renewable Energy is banking on 3D printing to overcome the obstacles.

Why Not Taller Wind Turbines?

Musk’s latest compensation windfall, which must be certified by Tesla’s board, comes days after he offered to buy Twitter for $43 billion, with analysts suggesting he could sell Tesla shares to help finance the deal.

Musk already is the world’s richest person, according to Forbes.

Tesla reported quarterly revenue of $18.76 billion and so-called adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) of $5.02 billion. Combined with the previous three quarters’ results, that surpasses milestones that trigger the vesting of the ninth through 11th of 12 tranches of options granted to Musk in his 2018 pay package.

CARMAT, the developer of the world’s most advanced completely artificial heart has successfully raised €40.5 million in funding. The raise is set to finance the production of their Aeson artificial heart, which the company hopes will provide an alternative treatment option for people with heart failure – a condition affecting around 6.2 million adults in the US alone [1].

Longevity. Technology: Beating around 100,000 times per day, your heart works around the clock to keep your circulatory system ticking. The steady sound of your heartbeat is a comforting constant throughout your life. Forming the centre of the circulatory system, the heart continuously pumps blood around the body to deliver oxygen and nutrients to cells. Due to this constant work, our hearts can unfortunately wear out as we age, with cardiovascular diseases continuing to be the leading causes of death globally [2].

End-stage heart failure is a serious condition that occurs when the heart can no longer transport blood throughout the body effectively. It most often affects the left chamber of the heart, which pumps oxygen-rich blood around the body, leading to biventricular heart failure. Vital organs like the brain, liver and kidney fail to get enough oxygen and nutrients to function properly. With few treatment options, end-stage heart failure sometimes requires serious intervention like heart transplantation – considered the gold standard therapy. However, due to the global shortage in organ donors, this is not always possible and there is a gap for a therapeutic alternative that could have huge implications for longevity globally.

For those not paying attention, Tesla has been unable to build cars in China for a few weeks as China shuts down due to a zero Covid policy. Here’s a short video about life in China:

China’s financial hub Shanghai has started easing its lockdown in some areas on Monday, despite reporting a record high of more than 25,000 new Covid-19 infections, as authorities sought to get the city moving again after more than two weeks.

Engineers at MIT and the National Renewable Energy Laboratory (NREL) have designed a heat engine with no moving parts. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency—a performance better than that of traditional steam turbines.

The heat engine is a thermophotovoltaic (TPV) cell, similar to a solar panel’s photovoltaic cells, that passively captures high-energy photons from a white-hot heat source and converts them into electricity. The team’s design can generate electricity from a heat source of between 1,900 to 2,400 degrees Celsius, or up to about 4,300 degrees Fahrenheit.

The researchers plan to incorporate the TPV cell into a grid-scale thermal battery. The system would absorb excess energy from renewable sources such as the sun and store that energy in heavily insulated banks of hot graphite. When the energy is needed, such as on overcast days, TPV cells would convert the heat into electricity, and dispatch the energy to a power grid.

Medical tech company Viz.ai, a developer of an AI-powered stroke detection and care platform, has pulled in a new investment of $100 million at a valuation of $1.2 billion, making it Israel’s newest unicorn (a private company valued at over $1 billion).

The company said Thursday that the Series D funding will be used to expand the Viz platform to detect and triage additional diseases and grow its customer base globally.

Viz.ai’s newest round was led by Tiger Global Management, a New York-based investment firm focused on software and financial tech, and Insight Partners, a VC and private equity firm also based in New York. Tiger Global has invested in Israeli companies such as cybersecurity companies Snyk and SentinelOne as well as payroll tech companies Papaya Global and HoneyBook. Insight Partners is a very active foreign investor in Israeli companies, with at least 76 local portfolio startups to its name including privacy startup PlainID, bee tech startup Beewise, and music tech startup JoyTunes.

A banking trojan for Android that researchers call Fakecalls comes with a powerful capability that enables it to take over calls to a bank’s customer support number and connect the victim directly with the cybercriminals operating the malware.

Disguised as a mobile app from a popular bank, Fakecalls displays all the marks of the entity it impersonates, including the official logo and the customer support number.

When the victim tries to call the bank, the malware breaks the connection and shows its call screen, which is almost indistinguishable from the real one.
