At Bank to the future we believe that important records and data should be in your control, secure from hackers and stored in a way it cannot be tampered with. Well, you’ll be glad to know that these problems will soon become history. Factom developed technology to tackle these issues and chose to raise part of their funding on our Online Investment Platform - BankToTheFuture.com Unlike many companies, Factom believes that data should never be stored with one organisation. It is simply too attractive a target for hackers. Unlike banks, Factom believes that customers should only share their important information as and when it is needed. Unlike governments, Factom believes that important records should be stored in a tamper proof way, transparently and impossible to be altered. ...and we agree. BnkToTheFuture.com is the largest Online Investment Platform with thousands of professional investors waiting to invest in Financial and Technological innovation. Go to our homepage and you’ll get to see the total number of professional investors, how much they have invested, and the amount of dividends that they’ve received. Factom was a perfect match for us. They had built technology that stored huge data on the Bitcoin Blockchain secure from hackers, scalable and in a way that can never be tampered. They had already funded the development of the not-for-profit side of their technology by issuing their own CryptoCurrency, but were now ready to fund the for-profit side of their business. They secured a partnership with MicroSoft, a contract to build smart Cities in China and an initial agreement to build a proof-of-concept product to store land title deeds for a government. They wanted funding from professional investors who believed in them and knew the value of their business. and they wanted the investment to come through fast, in different currencies and with a streamlined compliance and documentation process. A solution was found, and Factom decided to list on Bank To The Future. We gave Factom access to a global community of thousands of qualifying investors ready to invest in Financial and Technological innovation. We gave them a platform that complies with international financial regulations tailored for most major currencies and countries. We structured the investment in a way that meant they only get one registered investor. We cut out the painful admin, legal costs and problems raising further finance in the future, as compliance and documentation was completed by us in an optimised investment structure. And all under a “no win, no fee” agreement with no up-front costs. We provided all our investors with one investment agreement and a forum to communicate with the team quickly, efficiently and privately with additional investor protections. Investors can download all legal work, due diligence and certificates via our platform whenever they want. We also invested in Factom through one of our Venture Capital funds - Bitcoin Capital, meaning, investors got to co-invest with us on the same terms and our interests are aligned. If Factom floats on a stock market, is acquired in the future or pays investors dividends, investors get their returns minus our 5% fee. We built our Online Investment Platform with one purpose in mind - to prepare for a radically different future in Financial and Technological Innovation... Businesses just like Factom can raise finance in a safe, fast and effective way, while our investors get to allocate a portion of their wealth to an extremely disruptive and fast growing area that many are beginning to see could change the world of finance - FOREVER! Just like Factom, you can get involved by making a quick online application for finance at BankToTheFuture.com or register to see if you qualify to invest. http://bit.ly/1AJOQiZ

This video https://youtu.be/eXJHPDs4M3Y provides an easy to understand introduction to Blockchain Technology. Please leave comments and questions below the video. Here is the full transcript for your convenience: What is a Blockchain? A Blockchain is a distributed database that multiple parties share and everyone can trust. A Blockchain network provides a mutually trusted, transparent way of sharing and transacting. Each party participating in a Blockchain network maintains their own copy of the database. What makes Blockchain secure? Transactions on the database are atomic (this means that they're processed one at a time). The next transaction will be a different write or a read, but only after the preceding transaction has completed (or failed). Each write to the database is considered a ‘block’. Each new block contains a cryptographic hash (a unique fingerprint) of the previous block, creating a chain that can always be validated by checking the hashes back to the original root block. Before a block can be committed, all participants are required to validate the transaction and provide consensus that the block can be added to the chain. This effectively makes it impossible to add a record unless all parties participating in the blockchain agree the record is valid. Because all records are chained together by their hash value, once committed to the chain, all records are immutable (they cannot be changed). It is impossible to alter a previous record without altering every party’s copy of the chain. If one node is compromised, then it can no longer participate in the chain until it regenerates the true chain from the other participants. How does Blockchain prevent double spending? A major challenge of digitising assets is the potential to spend/redeem/use an asset multiple times. Because digital assets are much easier to forge than many traditional assets (such as currency, tickets, physical coupons, etc.), a secure system is required to ensure that an asset is only used once. With Blockchain, every time an asset is used or consumed, the owner of the asset signs the transfer with a private cryptographic key. This key is unique to the owner and is extremely difficult to forge. In order to initiate the transaction, the transferrer requires both the asset and their private key. The Blockchain will check both the validity of the key, and ownership of the asset. Therefore, even if the asset is cloned, it cannot be used without the private key. Once the transaction has been committed to the chain, the owner of the asset will have changed. This means, each node that receives a second transaction requesting transfer of ownership (or redemption, etc.) will see that there was a previous transaction that already transferred the asset and will reject that transaction. This prevents a second transfer block from being added to the chain. How does Blockchain ensure privacy? Personal data and identifiers are not required to be stored in the chain. Such data is stored as a hash value which provides both anonymity and security. The user may provide data such as their name, telephone number, email address, Facebook account id, unique user name, password etc. (in reality a combination of these values is used) to determine their identity. This data is hashed to provide a unique token that can only be recreated by providing the original values, and only this hash is stored to identify the party in the chain. Since it is impossible to obtain the input values by reverse engineering a hash value, the user is practically anonymous to all parties within the chain. But, they can be validated whenever required by providing the original values used to create the hash. How is PassKit utilising Blockchain? PassKit provides a private blockchain service to parties that wish to issue, record or redeem anything of value. This can be anything from loyalty points, punch card programmes, event tickets, boarding passes, to government identification, insurance policies or claim histories, tax records and educational transcripts. We utilise existing mobile wallet technology as a gateway for transacting, validating or querying our secure, private Blockchain networks. We ensure that mobile wallet content can be validated and trusted in a frictionless, realtime manner, by both consumers and by the businesses and institutions with whom they transact.

("Skytech" pronounced) players of the applications of the chain-Block developed by SCtech (ie software suppliers dedicated to the development of applications based on the chain-blocks for the management of the supply chain) Procurement (SC) processes: document management, traceability, ancestry and finance. They are currently engaged in (POC) proof-of-concept experiments to identify SC processes will benefit most from block-based applications. These POCs also help determine business case criteria. The software components based on the block-string in the stack build on top of each other, and includes features that expand gradually: Depth of the supply chain: Using traditional two-party exchange data, applications increasingly enable participants to reach SC partners further upstream and downstream in a peer-to-peer mode. Depth of Trust: Program allows SC partners to increase their confidence in the accuracy of the data exchanged and access to data based on the need to know. Standalone execution: The more string-based block applications extends along the first two, more independent drivers, they become manual intervention. Straight-through processing is SCtech's features. The following quick overview provides an assessment of the software components in the stack chain-based stack IT supply chain. Interoperability: The first column of the stack contains software applications that enable SC practitioners to exchange data between their business and enterprise partner resource planning solutions. Likewise, the provisions of this module connect ERP with business-to-business networks (such as Ariba, Basware, GTNexus, Tradeshift, Elemica, Covisint) through which SC partners exchange purchase orders, Supplier ratings, invoices and payment instructions. Finally, interoperability with block chains ensures that applications run on a distributed public or private book infrastructure. Confidentiality: With this second module, SC practitioners are able to select the data at the individual level - that they want to share with SC partners. The selected parties must be allocated special accessibility powers and an administration grants module rights, permits and revocation authority. Document: With secure interoperability and data access granted only to authorized parties, applications can now be used to dematerialize legal documents on paper, approve and tokenize them on the chain of secure recording blocks, tracking Document exchange flows and allow the transfer of ownership. Documents include receivables, debts and invoices. Chain-based applications in this module provides digital product memory and provide proof of revenue confidence for payments to a wide range of SC participants (ie SC depth) and increased levels of trust. The exchange of documents can no longer be automated between computer systems. Track / Origin: Origin of goods requires certificates and certification documents, which is why this module is based on the previous building block for the digital document. Blocking the application-based chain designed to interact with existing paper-based documents, contracts and assets (eg, letters of credit, bills of lading) is a prerequisite for tracking the origin of goods and services Assets. Authenticity / Certification: This module of the computer stack containing software-based block chain that ensures the documents and data are original, authentic and legitimate. Peer-to-peer reputation algorithms are an integral part of this component of the stack: To minimize threats to open up the community of SC, community reputation calculated through transaction peer feedback stories, help estimate peers Credibility and predict their future behavior. Identification: The software applications of this top component ensuring SC parts are really which they say they are. The software features of this module to create and manage identities by including relevant documentation, allows participants to access that identity, and allows authority participants to request identity certificates.

Hawk: The Blockchain Model of Cryptography and Privacy-Preserving Smart Contracts Andrew Miller (University of Maryland) Presented at the 2016 IEEE Symposium on Security & Privacy May 23–25, 2016 San Jose, CA http://www.ieee-security.org/TC/SP2016/ ABSTRACT Emerging smart contract systems over decentralized cryptocurrencies allow mutually distrustful parties to transact safely without trusted third parties. In the event of contractual breaches or aborts, the decentralized blockchain ensures that honest parties obtain commensurate compensation. Existing systems, however, lack transactional privacy. All transactions, including flow of money between pseudonyms and amount transacted, are exposed on the blockchain. We present Hawk, a decentralized smart contract system that does not store financial transactions in the clear on the blockchain, thus retaining transactional privacy from the public's view. A Hawk programmer can write a private smart contract in an intuitive manner without having to implement cryptography, and our compiler automatically generates an efficient cryptographic protocol where contractual parties interact with the blockchain, using cryptographic primitives such as zero-knowledge proofs. To formally define and reason about the security of our protocols, we are the first to formalize the blockchain model of cryptography. The formal modeling is of independent interest. We advocate the community to adopt such a formal model when designing applications atop decentralized blockchains.

This video shows why middleware and streaming analytics is relevant for any blockchain project. It discusses how to leverage stream processing and how to integrate with blockchain events. The focus was on integration of TIBCO StreamBase and Ethereum Blockchain. But the same can be done easily for any Hyperledger Blockchain like IBM's Fabric, IROHA or Intel's Sawtooth Lake, or others like R3 Corda or Ripple. For smart contract deployment, I use Browser Solidity and MetaMask. But the same can be achieved with TIBCO StreamBase (or BusinessWorks, too). The live demo can be watched on Youtube. The outlook includes some upcoming topics like - Live Visualization for Real Time Monitoring and Proactive Actions - Cross-Integration with Ethereum and Hyperledger Blockchains -Data Discovery for Historical Analysis to Find Insights and Patterns - Machine Learning to Build of Analytic Models - Application Integration with other Applications (Legacy, Cloud Services, …) - Native Hardware Integration with Internet of Things Devices Some use cases / real world examples: - Banking: Data Discovery for compliance issues, fraud or other anomalies - Stock / Energy Trading: Subcribe to events (e.g. price went over a threshold) – event correlation and proactive live UI - Manufacturing / Internet of Things: Supply chain management with various partner companies (maybe even various blockchains) - Many other use cases... Thanks to my colleague Steven Warwick for implementing the StreamBase connectors and demo!

Can bitcoin change how we communicate and share data online? In this episode of “Behind The Headline,” Jameson Lopp, a software developer at BitGo, tells host Mnar Muhawesh about the promise and potential of the blockchain, a key technology behind the digital currency that creates a new form of trust and security through a publicly shared ledger of transactions. As governments ramp up surveillance, blockchains can help us take back our privacy.
