Looking at the major differences between a private Blockchain with a public blockchain. Within a private blockchain we also know the participants in the network so we take a look at how we add a new participant into a blockchain network to know who they are.

Ethereum Q&A: Private chains misunderstand the fundamental value of blockchains

Keywords/phrases: Private chains fundamentally misunderstand the value of open, decentralised, permissionless, borderless blockchains. It is akin to the horse buggy manufactures adapting automobiles by replacing the internal combustion engine with a horse. "But we really like the fundamental technology behind Automobile. Pneumatic tires will fundamentally transform the future of transportation." If you choose to do a private chain, you are re-introducing counter-party risk and removing the fundamental security mechanism of consensus, which brings back a lot of the old problems. The existing banking system is fundamentally constrained by two things: very large institutions with the inertia of centuries of tradition, and the guilded cage of regulations which have kept small competitors out and not allowed them to do what Bitcoin does. It will be difficult for them to reconcile their future with this new disruptive technology.

Over the past decade, an alternative digital paradigm has slowly been taking shape at the edges of the internet.

This new paradigm is the blockchain. After incubating through millions of Bitcoin transactions and a host of developer projects, it is now on the tips of tongues of CEOs and CTOs, startup entrepreneurs, and even governance activists. Though these stakeholders are beginning to understand the disruptive potential of blockchain technology and are experimenting with its most promising applications, few have asked a more fundamental question: What will a world driven by blockchains look like a decade from now?

At Global Architecture Week 2015, we covered ‘Digital Currencies and Cash’ and their relevance to Tax and Welfare Authorities, concluding with the message: “It’s not about Bitcoin, it’s about the Blockchain”.

Blockchain technology has the potential to enable a new mutually trusted, transparent way of sharing and transacting. In the UK Public Sector, Sir Mark Walport’s report Distributed Ledger Technology: Beyond Blockchain encouraged Government to assess its early use and potential. Meanwhile in the private sector, Blockchain FinTech excitement among start-ups and venture capitalists remained strong for a technology promised to be “like a whole new internet for value exchange”.

But where are the real world use cases today? What is it that makes a use case more likely to succeed?

In this talk, Nick Meyne, Enterprise Architect, Capgemini shares and discusses a number of Capgemini examples.

Filmed at Capgemini Week of Innovation Networks 2016 in Telford, UK.

Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/cppcon/cppcon2016

This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges.

Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns.

C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do.

The primary purpose of the talk is to explain what blockchains are, increase understanding of the unusual challenges developers of blockchain software experience, and to demonstrate why C++ is a good choice to address them.

Neo & Blockchain News. Private vs Public Blockchains. Is NEO at risk because of centralised blockchains? How does Neo Blockchain work? Does this question of public vs private blockchain even matter? Hi everyone, this video is all about discussing the question of Public versus Private blockchains in the crypto-space. With the upward swing of NEO atm, it is particularly poignant to discuss NEO's future in terms of being a viable Blockchain in the Chinese and World Market. If you are interested in Neo or similar Blockchain technology, this video, however long winded, might be of some worth to you. It might also might not, lol. I don't monetise my vids, I just wanna connect with savvy thinkers and investors in blockchain tech. Hope this helps build your knowledge of the Bchain concepts that underpin the tech itself.

How can we push back effectively on authoritarian regimes and trends that stifle activism under a ruse of counter-terrorism and security? Governments across the globe have begun to pass laws and regulations that stamp out civil society and limit human rights. How can we work to enhance the resilience and sustainability of civil society and promote freedom of speech and assembly?

Types of Blockchains
There are three types of blockchain networks:
– Public blockchains
– Private blockchains (permissioned)
– Consortium blockchains
Public blockchains
• No access restrictions in a public blockchain and anyone can send transactions to it as well as become a validator.
• Some of the largest, most known public blockchains are Bitcoin and Ethereum etc.
Private blockchains
• A private blockchain is restricted and joining by invitation only. Participant and validator access is restricted.
• Enterprises adopting private blockchain technology and incorporate it into their accounting and record-keeping procedures with autonomy, securing sensitive data.
Consortium blockchain
• A consortium blockchain is semi-decentralized, operated by more than one organization.
• The administrators control users’ access rights to permitted/trusted nodes.
Private blockchain - disadvantages
• Blockchain tools and resources are controlled privately.
• If an attack is made on private blockchain servers, network could be compromised and transactions may be altered leading to adverse implications.
• Public blockchains like bitcoins are protected by the group mining effort, no...

Blockchain is good, Bitcoin is bad. How many times have you heard this echo chamber? It genuinely tilts me, so thought I'd make a video on it. In general, many of the people who tout this are talking about private blockchains, not public. Private blockchains are essentially upgraded distributed databases, and even then there are tradeoffs. While it may increase efficiencies overall, the opportunity is nowhere near as large or revolutionary as public blockchain is.

Bitcoin is the best implementation of such technology due to the size of its network. While mining pools are causes for concern (I'm looking at you Bitmain), Bitcoin has proven to be fairly resilient to central control. It is censorship resistant. It is not 100% immutable in the sense that one could create a longer chain that replaces another, but other than this fringe scenario, the erasure or reversal of transactions is not possible. As such, it is truly trustless. Private blockchains cannot achieve this. While they will provide value to the world, it won't be nearly as much value that public blockchains do in my opinion. Let me know yours.

In this video, I review CommerceBlock's upcoming initial coin offering.

In my point of view, this is an all star ICO. I am going to invest in this ICO.

Its my personal opinion, I am not giving biased recommendations. I am not a financial adviser. Discuss with your advisers before investing in ICOs.

We are building the first technology platform to bring a combination of trust minimized trade, decentralized contract execution, on-chain derivatives and asset backed token issuance to public blockchains.
