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.

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.

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. I am a novice so please feel free to correct me, I will make mistakes.

Scaling public blockchains such as Bitcoin and Ethereum is a long standing technical challenge. In this episode, we cover Zilliqa which has pioneered a design to scale public blockchain throughput with the number of nodes by sharding the blockchain. Sharding has been hitherto proposed as a scaling technique by Ethereum. Zilliqa is one of the first projects to propose a concrete design with an operational testnet processing a couple thousand transactions per second across several shards.
Our guests, Xinshu Dong (CEO) and Amrit Kumar (Crypto Lead), walk us through the objectives, protocol design and fundraising structure of this innovative project. We also briefly cover Zilliqa's novel approach to designing a smart contract language and execution environment.
Topics discussed in this episode:
- Sharding as a scaling technique
- Different kinds of sharding, including state sharding and non-state sharding
- How Zilliqa works under the hood - consensus algorithms & transaction processing
- Zilliqa's novel approach for a smart contract...

Detailed overview of public/private key encryption and live demo of exactly how digital signatures work on Mac, combining public and private keys and hash functions.
Welcome to episode 3 of my series on Blockchain/Bitcoin. I'm joined once again by my girlfriend Nadisha who is my classroom pupil...
I build on the hash function concepts from the previous episode and explain the basic concepts public and private keys and how to use them to create digital signatures - a key part of the bitcoin infrastructure.
We demonstrate in a Mac terminal how you can generate your own keys and encrypt and decrypt and sign your own resources - learning by doing always works.
We touch on bitcoin addresses, what they represent and how they are created.
Finally I go back for a refresh of the bitcoin blockchain browser and look at the first ever bitcoin transaction in the "Genesis Block" to show what a real bitcoin address looks like.

If you want to know more about how public key cryptography works, see the Wikipedia page on it: https://en.wikipedia.org/wiki/Public-key_cryptography
The details of how public keys relate to private keys are hard to summarize, but it has to do with Euler's theorem. Basically, using Euler's theorem there is some math you can do to a number given some parameters (which I'll call the public key) which allows someone with some other parameters (which I'll call the private key) to decipher the original number without having to do brute force factorization because there is a shortcut way to find the phi of a prime number.

This is part 23 of the Blockchain tutorial explaining what a ledger is.
This tutorial explains the differences between:
- a centralised and a distributed ledger
- a public ledger (permissionless ledger) and a private ledger (permissioned ledger)
In this video series different topics will be explained which will help you to understand blockchain.
Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons).
After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc).
Bitcoin's underlying technology is called Blockchain.
The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block.
Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application.
New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum.
Ethereum focuses on running programming code, called smart contracts, on any...

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.

This show I overview the CommerceBlock ICO, essentially making it easy for companies to adopt the efficiencies of blockchain and cryptocurrencies throughout business transactions.
The goal is to have a more reliable and auditable trial for trade and finance details between companies. Basically they are bridging private blockchains and public blockchains and are able to run federated sidechains to automate trade flow as smooth as possible. Developers can get paid in CBT tokens for joining, facilitating and helping the network and libraries go.
Commerceblock recently secured major investment from Global Advisors Holdings Lltd. as well as a significant commitment to the ICO Pre-launch CoinShare Fund 1 LP. CoinShares is the world’s first ethereum-denominated fund launched in June of 2017. These two entities intend to use Commerceblock’s innovations to scale and build infrastructure on top of their own sidechains.
Interestingly, Commerceblock is the first blockchain platform with their own open source BIP, Bitcoin improvement protocol called BIP 175, specifically is designed with a “Pay-to-Contract” protocol which creates unique codes for invoiced and contracts...

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.
