Blockchain is Eating Wall Street | Alex Tapscott | TEDxSanFrancisco – YouTube
Read MoreTrust is the expectation that the other party will abide by their commitments. That they will act with integrity. And it’s been very difficult to get people to do that. What if we could program that into the fabric of our economy? What if we had a new protocol, a trust protocol on top of which we could build any kind of business? So it’s an exciting time. One fraught with peril but also lots of possibilities. Because it appears that once again the technology genie has been unleashed from the bottle. Summoned by an unknown person or persons with unclear motives at a very uncertain time in history. This genie is once again at our disposal to broker, to fix a broken system and to transform the economic power grid and the old order of human affairs for the better if we will it.
What Is Hyperledger? How the Linux Foundation builds an open platform | Blockgeeks
While most other blockchain projects focus on cryptocurrencies and tokens, the projects around Hyperledger demonstrate a strong potential to build the backbone of non-monetary, high scaling industrial applications of blockchain technology.
Here are a few use cases:

Wal-Mart Stores Inc., the world’s largest retailer, was one of the first to get on board, just completing a trial using blockchain technology to track pork in China, where it has more than 400 stores. The time taken to track the meat’s supply chain was cut from 26 hours to just seconds using blockchain, and the scope of the project is being widened to other products, said Frank Yiannas, Wal-Mart’s vice president for food safety, in an interview Thursday.
“The problem is the data is only as reliable as the person providing the data,” said Weinberg, who recalls seeing everything in China from synthetic eggs to fake shrimp that still sizzle in a wok. “In most supply chains there is one or more ‘unreliable’ data provider. This means blockchain is likely useless for protecting against food-fraud unless every piece of data is scrutinized to be accurate.”
But blockchain is “light years” away from the system used by the global food industry today, which relies heavily on paper records, said Yiannas, Wal-Mart’s food safety chief. By recording the identity of those who input data into the chain, the technology removes the anonymity that has helped food-fraud to thrive, he said.
The role of humans in recording the supply chain will also diminish, said Yiannas. “More and more of these documents will eventually be captured in an automated way.”

Will the centre hold?
These efforts give a taste of what will be possible, says Albert Wenger of Union Square Ventures (USV), a venture-capital firm. He thinks that such decentralised organisations could one day disrupt the tech giants. At their heart, he argues, those tech titans are gigantic centralised databases, keeping track of products and purchase histories (Amazon), users and their friends (Facebook), and web content and past search queries (Google). “Their value derives from the fact that they control the entire database and get to decide who sees which part of it and when,” he says.
In some areas the blockchain may even make life easier for governments. Last year Dubai announced that it wants all government documents secured on a blockchain by 2020, a prerequisite for agencies to become completely paperless. The technology could also be used as a cheap platform to generate what poor countries lack most: more efficient government and trust in contracts. And some hope that the blockchain could make the United Nations work better by helping it keep track of all its programmes, creating transparency and reducing waste.

Read MoreInnovators Dilemma
It is difficult to innovate within your business model, because you will typically attempt to tie everything back to it, resulting in a shortsighted and limited view of what is possible. This is especially true if your business has a trust-related function (such as a clearinghouse). Current intermediaries will encounter the hardest change, because the blockchain hits at the core of their value proposition. They will need to be creative, and dare disrupting themselves while folding some blockchain capabilities under their offerings, and creatively developing new value proposition elements. They will need to realize that it is better to shoot yourself in the foot, rather than to have someone else shoot you in the head. This will not be an easy transition, because changing business models could be difficult to achieve in large organizations for a variety of factors.
Hardware Oracles: Bridging the Real World to the Blockchain
Cryptographically attestable anti-tampering sensors
To be able to securely report a reading (from any kind of sensors), the combination of the following is necessary:
- a cryptographic attestation of the sensor reading, authenticating the origin of the measure: each device has a private key signing outgoing payloads (with a nonce to avoid replays)
- an anti-tampering installation of the reader device, rendering it inoperable (by wiping the private key) in case of manipulation attempt (connect to another object, inject false stimuli, etc.)
These secure reading devices are called Hardware Oracles, and are the gateways from the physical work to the Blockchain realm.

Blockchains cannot access data outside their network on their own. An oracle – also known as data feed – is a third party service designed for use in smart contracts on the blockchain. They provide external data when needed and push it onto the blockchain.
Such conditions could be any data like weather temperature, successful payment, price fluctuations, etc. Smart contracts contain value and only unlock that value, if certain pre-defined conditions are met. When a particular value is reached, the smart contract changes its state and executes the programmatically predefined algorithms, automatically triggering an event on the blockchain. The primary task of oracles is to provide these values to the smart contract in a secure and trusted manner.
An oracle, in the context of blockchains and smart contracts, is an agent that finds and verifies real world occurrences and submits this information to a blockchain to be used by smart contracts.
There are four different types of oracles based on the type of use. We differentiate between software oracles, hardware oracles, consensus oracles and inbound and outbound oracles.

Why do we need Oracles?
Smart contracts confined to on-chain data are like sports cars on local roads. They’re purring with latent power, but can’t do anything really interesting.
To unleash their potential, smart contracts need access to the wide open vistas of data available off-chain, i.e., in the real world. A financial smart contract needs access to equity, commodity, currency, or derivative prices. An insurance smart contact must be aware of triggering events such as bad weather, flight delays, etc. A smart contract allowing consumers to sell online games to one another must confirm that a seller successfully transferred game ownership to a buyer.Latent power waiting to be unchained…
Today, though, smart contracts can’t obtain such data in a highly trustworthy way. And they can’t achieve data privacy. These deficiencies are starving smart contract ecosystems of the data they need to achieve their full promise.

Read MoreBlockchain: Massively Simplified | Richie Etwaru | TEDxMorristown – YouTube
Richie Etwaru, discusses the opportunity and implications of blockchain as a paradigm to slow/close the expanding trust gap in commerce. He unpacks blockchain to a level of simplicity to be consumed by those who are just starting to understand and explore the paradigm. He lays out a current state of commerce, suggesting that every company is currently at risk of being disrupted or incurring severe strain from a blockchain version of itself.
Every company in the world today, not just the intermediaries, are at risk of having competition from a blockchain version of themselves.
We are at the ground floor of a new paradigm in humanity that will change the human experience called Blockchain. The thing it is going to change is Trust.
Takeaway
Blockchain in one word: “Trust”
