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 :)
1) S'agissant des aspects descriptifs, remarquable effort de documentation, de compréhension et de pédagogie technique sur les origines et le fonctionnement de #Bitcoin, des #blockchains et des #cryptomonnaies. Résultat assez impressionnant de précision et d'objectivité
2) Présentation honnête de l'importance du courant #cypherpunk
- It doesn't have to be a disintermediator to generate value. This encourages permissioned commercial applications.
- It's short-term value will be predominantly in reducing cost.
- It's 3-5 years away from feasibility at scale.
2/n. Blockchain’s core advantages are decentralization, cryptographic security, transparency, and immutability. It allows information to be verified and value to be exchanged without having to rely on a third-party authority.
Super late to the party, but trying to understand the hype/see what early interesting apps/toys are being built on #blockchain/#crypto that aren't just exchanges/trading platforms/stores. What should I check out? Caveats: super beginner & SUPER skeptical as @rickyyean can attest
So far, Steemit at least looks interesting, but I'm finding pretty little else that's interesting. Brave and Metamask were also not beginner friendly at all to set up.
So update: tried out Peepeth on Toshi... lots of issues: 1) Had to pay gas to write my signup to the blockchain 2) Have to pay gas for any write transaction: sending a peep, following, etc. 3) BUT you can batch 15 actions together and write them at once to the blockchain...
2) First off, what is our national debt. As in, what form does it take. These are bonds, securities, etc, which are sold through the @USTreasury.
3) Obviously, these are IOUs from the US Federal Government. These are the basic building blocks of our debt. The more securities out there, the more our debt is, and when funds need to be raised more are sold, and people buy them because they trust in our country's stability
Here are my favorite quotes from this amazing book. #THREAD
1. "Bitcoin can be best understood as distributed software that allows for transfer of value using a currency protected from unexpected inflation without relying on trusted third parties"
2. "While Bitcoin is a new invention of the digital age, the problems it purports to solve - namely, providing a form of money that is under the full command of its owner and likely to hold its value in the long run - are as old as human society itself"
