(Part 2) Best products from r/BitcoinAll

Author: fbonomi

Content:

>TLDR: Evidence that Dave Kleiman (the dead partner of Wright) was also a Windows programmer with a very strong background on security.

>He developed a product (called S-Lok) distributed by S-Doc as a security tool (a sort of hardening tool-kit)

>At S-Doc, cryptography was heavily used to develop several products, broadly aimed at reliable and verifiable transmission of data and messages, centred around the idea of a an "unalterable, encrypted audit log system".

>I think this paints Kleiman as a very plausible author of the first Bitcoin software

>When the news that Craig Wright could have been Satoshi emerged, I purchased his book “ The IT Regulatory and Standards Compliance Handbook ” in order to search for clues that he was Satoshi.

>I was disappointed. The book is published in 2008; more precisely, it says “this week” referring to February 2008 (p. 644), terefore when Satoshi would have been fully working on Bitcoin.

>There book deals with other subjects, but there are several occasions where something bitcoin-like could have emerged. For example, all mentions to cryptography are rather vague (ok, the book’s subject does not require a LOT of crypto, but nevertheless...). Digital signatures are treated (they are generally called “electronic signatures”), but again nothing that echoes concepts that would return in Bitcoin.

>So, no proof that he was NOT Satoshi, but no evidence that he had similar interests in that period, either.

>I then started giving a look at the books authored by Dave Kleiman. There are a few, generally dealing with Windows security including one co-authored (among others) with Craig Wright .

>Then I stumbled on his book “ Winternals Defragmentation, Recovery, and Administration Field Guide ”
There is an interesting bio of Kleiman in that Amazon page, listing his titles, and containing:


>He has developed a Windows Operating System lockdown tool, S-Lok ( www.s-doc.com/products/slok.asp ), which surpasses NSA, NIST, and Microsoft Common Criteria Guidelines.


>So, we now know that Kleiman was a security expert, was good at Windows security, and had written software for Windows.

>The web site for the company seems down, but archive.org helps here:

> https://web.archive.org/web/20080828130153/http://www.s-doc.com/products/slok.asp

>This is a mirror of the page about the program written By Kleiman on the company’s site, taken in the months he was probably working on Bitcoin.

>The software is described thus:


>The S-LokTM system is a Comprehensive System Hardening Solution that dramatically enhances your OS security by appropriately altering your system registry, security database and file system ACL's.


>(from its technical brochure )

>Nothing too exciting here. A software related to security, but a quite boring one.

>It gets more interesting when you start looking at the line of products that were being developed at s-Doc. This page lists a few PDFs about them: https://web.archive.org/web/20081121211338/http://www.s-doc.com/technical/technical.asp

>mirrored in https://drive.google.com/folderview?id=0Bwr9mVDA8j3LU3ozYm9uOVpuSjA&usp=drive_web

>Basically, it was a suite of products allowing cryptographically secure distribution of data and messages:


>S-docâ„¢ develops products that solve the most urgent business problems of the Information Age. They protect sensitive information during transport over an open network and when at rest during server storage


>It’s nothing specifically bitcoin-like, but yet it’s an environment heavily imbued with cryptography:


>The encryption algorithm (Triple DES, Skipjack or Rijndael/AES at a key length of 168, 96 and 128 bits, respectively), chosen at the time of system installation, is seeded by SITT using an RNG (Random Number Generator). Either a standard hardware white-noise generator or FIPS 186-2 approved pseudo-algorithm generates the unique encryption key for each and every transaction.


>The core of the system seems to have been “an unalterable, encrypted audit log system”.


>S-doc solutions include an unalterable, encrypted audit log system. All transaction activity and user access is available to authorized administrators, originators and compliance officers without exposing the underlying information.


>(reminding of zero-knowledge proof)

>What I also found interesting is the document about S-Doc's applications in finance and insurance:
https://drive.google.com/file/d/0B4YULdyuY7PvR1JjdVhxNFAwdWs/view?pref=2&pli=1

>Once again emphasis is placed on the “unalterable, encrypted audit log system” log.

>In conclusion: There is of course no direct evidence of Bitcoin in the material, but it can be seen that S-Doc was a place where creative uses of cryptography were usual.

>Also, concepts like “unalterable, encrypted audit log system” were common knowledge at S-Doc.

>Dave Kleiman was an accomplished Windows programmer, with exactly the technical capabilities and the cultural history one would expect from the author of the Bitcoin software

>I think he is by far the best candidate for this title.

>Thanks, Dave

>Bitcoin is breaking through a major level of resistance at $9k as the rally continues. This article looks to provide insights behind some of the key metrics and other fundamental aspects backing Bitcoin.

>Remember, when we see a pump in price, it doesn't necessarily mean that one can pinpoint the reason fueling the higher valuation. A whole plethora of factors outside the public knowledge may influence such decision to buy the token, however, by analyzing the latest key fundamental advancements, we can assess how well justified the rise is.

>#1 Google Trends: 'Bitcoin' Picking Up</strong>

> </strong>

>#2 Social Media Hype Solid</strong>

>The social media activity via Twitter and Reddit on Bitcoin has been consistent since early April. We've drawn a line around 22.5k, which when broken, should provide further evidence that the hype is truly back.

>We like to use the website Solume.io illustrates the change in sentiment, as it helps us track the social activity on Reddit and Twitter.

>#4 Bitcoin Lightning Network Matures</strong>

>According to Bitcoinist: "Data showing current activity on Lightning’s Bitcoin mainnet implementation reveals a network capacity of $148 million, up from $80 million April 10. At one point, over 2000 active public nodes were available to process transactions, which can confirm almost instantly for a fee of less than one satoshi per byte.What’s more, the network has now reached 7000 active channels."

>#5 BTC Over the Counter Activity Huge</strong>

>As CoinLive has reported via Twitter: "Our network of Insiders telling us between 5000-10.000 BTC are being sold every week OTC by Chinese BTC miners to Israeli buyers - Wall Street type - as they look to accumulate a big hand in BTC."

>We also noted the tweet back in early April via Jeremy Gardner @Disruptepreneur: "OTC market demand for bitcoin right now is unlike anything I’ve ever witnessed. Several asks for multi-billion dollar blocks..."

># 6 Bitcoin Market Opens to 1.6 Billion Muslims</strong>

>An Islamic scholar recently declared Bitcoin “permissible” under Sharia law, which opens the market to 1.6 billion Muslims around the world.

>‘Is Bitcoin Halal or Haram: A Sharia Analysis,’ a report written by Muhammad Abu Bakar, a certified Muslim legal expert, analyzes whether cryptocurrencies fall under halal or haram (prohibited) based on Islam’s strict definitions of money.

># 7 End of US Tax Season Clears the Path for Fresh Capital</strong>

>"Selling pressure in cryptocurrencies could ease after tax day", those were the words from Tom Lee, the head of research at Fundstrat Global Advisors.

>Lee was quoted via Bloomberg earlier in April:

>"The April 15 income-tax filing deadline is contributing to crypto’s falling prices as investors who won big betting on the digital tokens sell some of their remaining holdings to pay $25 billion in capital-gains levies, Tom Lee, the head of research at Fundstrat Global Advisors, wrote in a note Thursday. Bitcoin dropped more than 40 percent over the past month, including a 2.4 percent decline on Thursday to $6,664 as of 9:39 a.m. in New York.

>“This is a massive outflow from crypto to dollars,” Lee wrote. “Historical estimates are each $1 of USD outflow is $20-$25 impact on crypto market value.” Lee says that $25 billion prediction -- derived from his estimate that U.S. households had $92 billion in taxable gains from cryptocurrencies in 2017 -- would represent 20 percent of capital-gains tax receipts to the U.S. Treasury. He estimates total capital gains receipts will hit a record $168 billion for tax-year 2017."

>#8 Technical Breakout Sees Further Shorts Liquidation</strong>

>The area of resistance at $9k represents a major hurdle, so when it broke, some shorts saw their stops triggered which creates an initial flash-type move on the combination of shorts buying back to close their positions and new longs coming in.

Not enough of us are asking this question- thank you. You’ll need to create an inheritance plan that doesn’t include putting your seeds in your will! If you’re like me, and your family isn’t into crypto, then making a written plan will help them. I used the book Cryptoasset inheritance planning this spring to make my plan. It wasn’t hard once I made time to do it and the book helped a lot. Good luck!
