I was recently contracted to consult with a company working on a Blockchain product. After 30 minutes; I made most of their engineering team realise they weren’t building a solution to a problem. Their marketing/corporate team not so much. A thread...
The company is building #blockchain based solution for maintaining health records. Health records should be private and #blockchain with its encrypted store seemed like a great solution to them. I asked them a series of Q&A to help them understand their solution.
1. Do we need to share the encrypted data?
Yes, with doctors & others. If you have to share results with doctor in plain text what is the point of having it encrypted in the first place? The data will just leak out.
2/ #Sweetbridge will announce Monday (10/29) in joint press releases news regarding a major award relating to the use of their loyalty system. Sweetbridge won out of 316 projects from 54 countries in what was "probably one of the highest-quality competitions in the space." 🏆
3/ #Sweetbridge will also announce on Monday with a press release from the State of #Arizona its approval and acceptance into the Arizona sandbox for the first tokenized asset lending platform to get approval in the US for title loans. 🏦
1/ After listening, and based on prior admiration and argument, I must conclude that @leashless is wrong about everything; as I was when I started down this revolutionary path. In "The Promise of the #Blockchain" it was stated that this was a power shift from lawyers to geeks...
2/ But such a shift isn't going to save us. Incentives are a continuation of rivalrous games; and in another era of unequal power dynamics our toxic human bickering simply continues unto death opendemocracy.net/digitalibertie…
1/8 It’s time to set the binance record straight and let the world know the truth. The binance - DGB story starts with us refusing to pay the “listing fee” last summer/fall. And continuing to refuse to ever pay it for the last 12 months.
2/8 Several key members of the DGB community were accused of being Chinese spies last fall in WeChat groups attempting to undermine CZ... Groups none of us were ever part of or aware of since none of us use WeChat. Major miscommunication here.
3/8 Binance used our social media attention for the Citibank Tech4Integiry event in 2017 to gain attention for itself after first launching. Several twitter polls were won for DGB and a listing was “promised” on several occasions.
If you want to know my opinion of how @timberners_lee's #Solid will impact "tech giants", watch this video (actually, x3) from 2010; the bulletpoints are:
- facebook killers, aren't
- there's plenty of room for alternatives
- first it must grow
The media loves zero-sum, david/goliath stories, and thereby often causes doom ("ello") & even tragically suicidal levels of stress ("diaspora*") to people who are foolish enough to pitch themselves/their platforms as the antithesis of "social media giantism; so do please beware.
1. The @CNIL makes clear that its goal issuing this publication is to provide concrete guidance to actors in the space. This is to be applauded. Many in this space try to build compliant systems but are having a hard time figuring out what this entails.
2. *Data controllers*: unsurprising: where users directly engage with the ledger they can sometimes be controllers.
This, however, is only so where natural or legal persons exercise a professional or commercial activity (broad interpretation of household activity).
1/ a quick thread on protocols focused on location. location data is leveraged by many consumer services (Google Maps, Uber), but also by military and industrial applications. now teams are #blockchain-ing this data to make it tamper-proof (secure), verifiable, and trustless.
2/ furthermore, new applications like self driving vehicles, AI, and increasingly digitized consumer, industrial, and military services will rely on secure location information services to deliver service. example - in 2012, a military drone was hacked and "stolen" by students...
3/ several projects are working on a new form of consensus called "proof of location" to design new mechanisms for collecting, verifying, storing, and sending data about location to the services and applications that consumer this data. let's dig into proof of location.
1) The narrative, promise, and objective of #blockchain has been skewed and altered into some Frankenstein clusterfuck. I see so many clueless people talking about competition, applications, tx throughput, speed, governance. When did this space derail and spiral out of control?
2) The purpose of a blockchain is to recreate objective truth or reality and the *only* way we can achieve this is when its security exceeds any one person's ability to alter its records or censor future ones. Therefore, the *only* application of a blockchain is security.
3) Blockchains are *NOT* application platforms nor are they communication mediums. They are not built for this functionality as they are highly inefficient. They are first and foremost consensus apparatuses to trustlessly discover truth and create objective reality.
We will provide a formal definition of a DLT system and explain some of the key concepts.
2/ Before diving into the key concepts, it is important to understand that unlike 'traditional' databases, DLT systems are designed to operate in an adversarial environment.
3/ That doesn't necessarily mean that there are adversaries actively trying to attack or sabotage the system; rather, a DLT system should be designed to tolerate the potential presence of malicious actors - to a certain extent.
We purchased a box of this Dole sweet corn. 🌽 Very tasty! Got me thinking:
Can #Blockchain technology really help with supply chain traceability & authenticity of goods?
- Is this corn packaged by Dole?
- Is it really from stated country of origin?
- Really non-GMO & organic?
My thoughts about whether the so-called #Blockchain technologies can be applied to #RealWorld activities:
Regarding this box of corn, in terms of it being: genuine, nutritious, organic, non-GMO, from stated country, unspoiled & safe to eat: Who am I solely & implicitly trusting?
A hint for the correct answer? Apply the same questions above & tell me about this @LouisVuitton handbag.
Do I trust the brand, manufacturer, selling merchant, or delivery person?
Can #Blockchain technology actually help with authenticity & supply chain transparency? Not really!
We are currently in the keynote. The speaker is talking about how popular Neo4j is
Keynote now telling us about all the new Neo4j features. Examples: location filter, including 3d. Auto cache reheating. I'm interested to know if auto cache reheating is working with query patterns or meant to replace them or what
Just had quite an interesting experience with @verisart's #blockchain for securing authenticity certificate, provenance, and other metadata around a recent purchase of art that I made, and now have a few thoughts to document for later reflection. 1/
First, while my honest initial impression was "huh, shame that someone's gone and blockchained something as pure as art as part of this DAPP money grab," it is in the end quite nice to have a cert ostensibly locked in, & useful if I ever decide to sell it, give as a gift, etc. 2/
That said, there are some hiccups along the way that need to be kept in mind when trying to convince people to flow with this "Don't want to trust humans? Easy, just trust #blockchain and peripheral technology [that was developed by humans]!" cognitive dissonance. 3/
Some large companies are getting into #Blockchain e.g. IBM, Maersk, etc. That does not mean that these companies nor institutional investors will invest in present day public blockchains nor their associated tokens. Don't take me for my word, read McKinsey's view on Blockchain.
The day a #bitcoin ETF gets approved, $BTC should spike hard, and all alts follow suit. Yet we call institutional money "smart money" for a reason. Institutional investors will likely differentiate the good from the bad. After the initial pump, cyrpto correlations should plummet.
Corollary: the inception of a bitcoin ETF should provide great money making opportunities in Alts/BTC pairs.
My keynote, tomorrow #Computing2018: "No, let’s not put it on the blockchain".
"To carve out some scenarios where blockchain optimist narratives fall short, & specific properties of distributed ledgers & blockchain work against requirements. Includes GDPR, but no 20M fines."
#blockchain Keynote was well received.
The scenarios in this thread, link to slides at the end. 1. Short-term information of any value. Everybody will have to keep it forever and you can't get rid of it.
2. Information that will remain valuable over a longer period.
Of course you encrypt, it but while it's forever on the blockchain, the crypto may be proved broken, Moore's law may cause key to be too short, or quantum may happen (yeah right). I said "crypto", I meant it :)
