With a clinical version of PathAI‘s computer vision-based pathogen detection service still at least one year from coming to market, the diagnostic technology developer has snagged $ 60 million in its latest round of financing.
The company’s tech is used by doctors to analyze cell samples taken from patients to determine the presence or absence of bacterium, viruses, cancerous cells or other disease causing agents.
These days, PathAI’s technology is used less in hospitals for patient care and more by pharmaceutical companies developing new drugs, according to the company’s co-founder and chief executive, Dr. Andy Beck.
“Our biggest focus today is a research platform we use it to examine new therapeutics for serious diseases,” Beck says. “We see that as a really important problem for patients… accelerating how we get safe and effective medicines to patients.”
That’s an attractive market given that pharmaceutical companies have more money to spend on new technology than hospitals.
When the company does work with pathologists, they’re using the technology for research purposes, says Beck. Any clinical diagnostic work would have to go through trials and be approved by regulators, he says.
“For this direct clinical use it’s in the one to two year timeframe,” he says.
General Atlantic led the company’s latest round with additional capital coming from previous investors General Catalyst, 8VC, DHVC, REfactor Capital, KdT Ventures, and Pillar Companies.
PathAI has grown its staff to over 60 employees in the past year, and the company has signed partnerships with Bristol-Myers Squibb and Novartis .
As a result of the financing, General Atlantic managing director, Dr. Michelle Dipp will take a seat on the company’s board.
“PathAI’s work could radically improve the accuracy and reproducibility of disease diagnosis and support the development of new medicines to treat those diseases,” said David Fialkow, Managing Director at General Catalyst, in a statement.
On April 16, RSK Labs chief scientist Sergio Demián Lerner published a new research study concerning the earliest blocks mined on the Bitcoin network. The report concerning one of Bitcoin’s earliest miners provides strong evidence to suggest that a single miner processed 22,000 blocks. Additionally, Lerner has released a new website called Satoshi Blocks that aims to help crypto enthusiasts visualize mining during the protocol’s earliest days.
New Data Stemming from Bitcoin’s Earliest Miners Hardens Prior Evidence
Years ago, independent researcher and cryptographer Sergio Demián Lerner released one of the most in-depth studies concerning Bitcoin’s earliest mining periods. According to his first study published on April 17, 2013, the vast majority of the initial BTC mined was done by a single miner. Moreover, Lerner produced data sets from his blockchain analysis that tracked the extranonce fields within the coinbase field stemming from the coinbase transactions themselves. At the time Lerner estimated that the miner was able to gather precisely 1,814,400 BTC. In addition to this large number of mined coins, 63% of those coins, or 1.1 million, have never been spent since the day they were created.
Fast forward to six years later and Lerner has published another rigorous study that provides an even stronger argument that backs his prior claims. The latest paper, called “The Return of the Deniers and the Revenge of Patoshi,” at first discusses Lerner’s original study and how he originally came to his previous conclusion. Lerner detailed how he found the information in the extranonce field and how certain flaws revealed information in a “non-privacy preserving way.”
Lerner’s paper then discusses the single miner who has been dubbed ‘Patoshi’ and describes how he was able to find the miner’s pattern. Lerner explains how a few people have accepted the existence of the Patoshi pattern, a few years on, yet believe multiple miners may have been synchronized or there was some form of an early mining pool in place since the genesis block. Lerner debunks these arguments with many reasons and by explaining various factors including:
- 99.9% of all Patoshi blocks are unspent.
- Each Patoshi block “links” to a block in the pattern set, but not to any of the remaining blocks.
- There are some time intervals where the Patoshi pattern interrupts abruptly.
- Mining pools were invented several years later.
- Mining pools were created to reduce reward variance due to the low individual probability of solving a block, but during 2009 single miners could easily solve blocks frequently.
By the end of 2013, Lerner said he had found proof “beyond any doubt, that the pattern was real, using a completely different method.” His latest study describes how he discovered that all of the blocks mined by Patoshi were identifiable by a depleted range of nonces used in processed blocks to a specific range. From 2014 to early 2019, Lerner didn’t have much more to add to his prior research and there were a few other studies published recently that suggest Patoshi only mined around 700,000 coins. However, Lerner’s latest study “proves with overwhelming probability” that a single miner extracted all of the coins in his Patoshi pattern, which is well over a million BTC. The researcher’s new argument is based on computer clocks because even in the early days miners used a local computer’s clock to timestamp blocks after processing them.
“If you’ve studied the Bitcoin protocol, you’ll know that block timestamps are not necessarily monotonically increasing,” Lerner writes. “This is true from the Bitcoin source code 0.1.0 to the latest version of Bitcoin Core that had an internal miner (before mining pools were created).”
Clocks and Timestamps
Some of the latest evidence Lerner provides also concerns why he strongly believes the single miner extracted close to 1.1M coins, which is even more than the initial 1M BTC discovered by Lerner years ago. For instance, Lerner states that “computer clocks can be unsynchronized from each other,” “timestamps were not updated continuously during mining,” and “block timestamps are adjusted by the Bitcoin software to match the median time of the peers that are connected to a node.” Because of these reasons, the study notes that the same computer will almost never reverse its own timestamps and “the delta between inverted block timestamps indirectly measures the hashrate of the parent block miner.”
“There are no time inversions between Patoshi blocks — Zero — This result is very relevant considering the Patoshi blocks account for 43% of all the blocks in the first 50k. I’m open to considering other explanations, but for me, this can only mean one thing — There is a single PC clock whose time is stamped in the Patoshi blocks.” Lerner’s paper continues:
A single software that controls how block templates are created — A single miner.
The RSK Labs chief scientist concludes that there is evidence that links the Patoshi patterns to Satoshi but he prefers to stop there and “leave Patoshi alone once for all.” Lerner believes the evidence he provided is reliable but he expects more people to deny the information in forums. Lerner also infers that he has discovered a more precise figure and coded a more accurate pattern-following algorithm which can be viewed on his new site satoshiblocks.info.

In the last two weeks, cryptocurrency prices have seen significant volatility and during this time onlookers have noticed large bitcoin whale movements once again. Data stemming from blockchain analysis indicates that over the last 48 hours, unknown whale wallets moved over 20,000 BTC ($ 101 million), showing another large migration not seen since last February. Additionally, bitcoin cash whales have accumulated 1.1 million BCH in the last five weeks.
Whales Have Moved $ 300 Million Worth of BTC Over the Last Week
Bitcoin whale watchers are at it again, monitoring exchange order books and blockchain transactions to uncover clues about the next big market cycle. In February, news.Bitcoin.com reported that large BTC holders captured more than 150,000 BTC ($ 762 million) since Dec. 17, 2018. Similarly, the top five largest BCH holders managed to gather 138,014 BCH ($ 39 million) since the same time last year. After a period of accumulation, both cryptocurrencies’ fiat values were much lower than today, with BTC priced at $ 3,800 and BCH at $ 135 per coin. On April 12, BTC is priced just above the $ 5K zone and BCH is averaging $ 285 per coin across global exchanges. Over the last few days, armchair sleuths noticed a total of 20,378 BTC ($ 101 million) migrating from unknown wallets to other unknown wallets and exchanges.
Blockchain detectives think that the wallets are not preparing to sell the BTC because 9,939 BTC moved separately to an unknown wallet, while 10,439 BTC did the same to another random wallet. From these movements, onlookers then started noticing an extreme amount of accumulation taking place which saw 42,616 BTC ($ 215 million) leave various cryptocurrency exchanges in the last 24 hours. Trading platforms that saw large withdrawals include Poloniex, Bittrex, Bitfinex, Binance, Huobi, Okex, Kraken, Coinbase, and Korbit. The 42,000 BTC movement took place as BTC dropped below the $ 4,900 range during the early morning trading sessions on April 12.
Central Banking Policies Push Crypto Accumulation Higher
On April 10, BTC prices spiked to a high of $ 5,345 on Bitstamp and analyst Travis Kling of Ikigai Asset Management and Naeem Aslam, chief market analyst at Think Markets, indicated the Federal Reserve was the primer. Cryptos jumped more than 20% almost immediately after the U.S. Federal Reserve’s FOMC report which stated the central bank would not change current interest rate policies. Kling, Aslam, and London-based data researcher from Tokenanalyst, Sid Shekhar, have noticed whale wallets accumulating massive amounts of crypto in the last few months and even more so after the Federal Reserve’s decision.
A big indication of this accumulation can also be seen in the BTC and BCH networks’ unspent transaction output (UTXO) set size growth. Both assets’ UTXO size has grown significantly and crossed levels not seen since 2017’s all-time price highs. History shows that when the UTXO set size grows and accumulation takes place at this speed, a bull rally usually follows a few months later.
Bitcoin Cash Whales Wallets Obtain 1.3 Million BCH Since February 25
Our research from February shows that the wealthiest BTC whales holding between 1-100 BTC actually have less coins this April. Back in February, the top 1-10 and 1-100 coin holders held roughly 5,908,501 BTC but since then they have parted ways with 12,914 BTC (-$ 65 million). The biggest bitcoin cash holders have accumulated a lot of BCH since our report in February. The richest BCH whales have managed to capture 1,330,415 BCH or $ 377 million at the time of publication. This indicates a lot of BCH whales seem optimistic about the future of the decentralized currency and last week’s 95% price jump showed bitcoin cash markets have seen significant demand.
It’s hard to say what the giant crypto whales are up to when all these coins start moving around, especially in multi-million dollar increments. Many traders believe the bottom is in for most cryptos right now and market actors have initiated an accumulation phase. Other observers are still very skeptical and think that we could see another big drop in the future, even lower than what people are currently calling the bottom. Vinny Lingham, often referred to as the “oracle” for his correct predictions, believes BTC must withstand 24-48 hours above the $ 6,200 range in order to remain bullish. Whatever the case may be right now, BTC and BCH whales are moving large numbers of coins around and whales always seem to be one step ahead of the public when it comes to preparing for large market spikes and dumps.

Rela (热拉), a popular dating app for gay and queer women, has exposed millions of user profiles and private data because a server wasn’t protected with a password.
Rela disappeared from app stores in May 2017 after it was reportedly shut down by Chinese regulators, though the government never confirmed it took action. But the app returned a year later, according to its app store listing, on a different cloud provider. LGBTQ+ rights in China remain highly limited, even though it was decriminalized in 1997. Many in the community still fight discrimination and attitudes have been slow to change.
Victor Gevers, a security researcher at the GDI Foundation, found the exposed database this week, he told TechCrunch, containing more than 5.3 million app users.
It’s believed the database had been exposed since June 2018, a month after the app returned, Gevers said.
Each record included their nicknames, dates of birth, height and weight, ethnicity, and sexual preferences and interests. Records also, where users allowed, included their precise geolocation. The database also contained over 20 million “moments,” or status updates — including private data.
“The privacy of five-plus million LGBTQ+ people face a lot of social challenges in China because their are no laws protecting them from discrimination,” said Gevers. “This data leak that has been open for years make it even more damaging for the people involved who were exposed.”
In a brief response, a company spokesperson confirmed the database had been secured.
Gay dating apps remain big business — even for companies in China, despite the legal complexities that’s seen several major apps shut down. Zank, a popular app used mostly by gay and bisexual men, was shut down in April 2017 citing the government’s rules for broadcasting pornographic content.
Yet, more established apps like Blued remain popular in the country.
Chinese gaming giant bought a 60 percent stake in U.S.-based gay dating app Grindr in 2017 and later acquired the entire company, but is reportedly up for sale amid concerns that the company poses a risk to U.S. national security.
