Many Machine Learning and AI algorithms are centralized, with no transparency in the process. Now a blockchain-based start-up aims to improve transparency bias in business workflows.
Millennials’ embrace of Bitcoin could see it “crowd out” gold in the long term, JP Morgan writes.

The new Nvidia GeForce RTX 3090 is a gaming powerhouse, but that’s not all it can do. According to the makers of a popular password recovery application, the RTX 3090 is also good at brute-forcing passwords. That’s great if you forget an important password, but that’s probably not why people are using such tools. The latest Nvidia cards could make cracking someone else’s files almost trivially easy.
The RTX 3090 is Nvidia’s latest top-of-the-line GPU with a GA102 graphics processor sporting 10,496 cores and 24GB of GDDR6X memory. It is monstrously, obscenely powerful by today’s gaming standards, and comes with a correspondingly high price of $1,500, give or take a few hundred depending on supply. With a focus on high core counts, GPUs are also great for parallel computing. That’s why you couldn’t even buy a GPU for several months when Bitcoin was at its peak. In the same vein, GPUs are very good at cracking passwords.
Passcovery recently updated to add support for RTX cards like the 3090, and it vastly increased the speed of brute force attacks. In the past, it wasn’t practical to guess every possible password until you hit on the right one — computers just weren’t fast enough. However, a GPU can do that quickly enough to find passwords in certain instances. With v20.09 of the Passcovery suite, a relatively modest GTX 1060 can go from 3.4 million guesses per second to 669 million per second. This version of the software added support for RTX 3000-series cards, which might be a problem for your weak passwords. The RTX 3090 is almost seven times faster in GPU compute benchmarks than the 1060 — that’s a lot of guesses per second.

Whenever I tell my friends about the potential of Quantum Computing, for example, how a Quantum Computer (QC) can do a large number of calculations in parallel worlds, they look at me like I’m kind of crazy.
Venezuela has poor internet infrastructure. Using Blockstream’s satellite technology to broadcast Bitcoin transactions could get around that.
While there’s no launch date yet, the People’s Bank of China is likely to be the first major central bank to issue a digital version of its currency, the yuan, seeking to keep up with — and control of — a rapidly digitizing economy. Trials have been held this year in a handful of cities and tests have started with some e-wallets and online apps, with the Covid-19 pandemic and need for social distancing providing a new sense of urgency. Unlike cryptocurrencies such as Bitcoin, dealing in the digital yuan won’t have any presumption of anonymity, and its value will be as stable as the physical yuan, which will be sticking around too. Behind China’s rush is a desire to manage technological change on its own terms. As one PBOC official put it, currency isn’t only an economic issue, it’s also about sovereignty.
Not all the details are out, but according to new patents registered by the PBOC and official speeches, it could work something like this: Consumers and businesses would download a digital wallet onto their mobile phone and fill it with money from their account at a commercial bank — similar to going to an ATM. They then use that money — dubbed Digital Currency Electronic Payment, or DCEP — like cash to make and receive payments directly with anyone else who also has a digital wallet. Some questions remain, including the impact on Big Tech companies such as Ant Group Co. and Tencent Holdings Ltd. that already offer payment services.
A project is aiming to create a “new blueprint for the future” that marries IoT and artificial intelligence, all through the adoption of blockchain technology.

The Lygon blockchain platform, which runs on IBM Public Cloud, has reportedly successfully conducted its pilot since last year with Australian banks ANZ, Commonwealth Bank of Australia (CBA) and Westpac and a group of 20 Australian businesses.
Banks are expected to issue bank guarantees in just one day once they implement Lygon compared to the current paper-based guarantees that can take a month. The three Australian banks and retailers Scentre Group and IBM are planning to expand the Lygon platform for commercial use, according to a report on Sept 1.
A bank guarantee is a type of financial backstop offered by a lending institution. The bank guarantee means that the lender will ensure that the liabilities of a debtor will be met. The financial guarantees are said to be needed as part of retail property leases and from this month. Lygon chairman Nigel Dobson added that:
“The commercialisation of the Lygon platform represents a significant milestone for blockchain technology in Australia and globally. In digitising a bank guarantee, we’ve essentially transformed a three-way contract. We’ve digitised the paperwork, the process and the legality behind it…”
