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.
This frenzy of bitcoin and blockchain is exaggerated and turned into a global casino for the participants. For now that is all . There is not even one practical application of blockchain at work solving or enhancing enterprise applications. And the reason for this is the fact that blockchain is encumber some , slow, utilizing extensive amount of computation and energy to validate block of transactions. Although the concept of getting rid of centralized trusted parties is the key attribute of blockchain technology, the implementation and speed of process is not yet up to par with the needs and demands that are currently solved by centralized trusted parties. Bitcoin thus is only serving as a token of participating in the Ponzi game of global casino it has created. Every newcomer joins in hoping to sell bitcoin to the next guy for a higher price fueling the demand till it implodes and all the late comers hold the bags. Very unhealthy for masses . And it will not serve or solve any of the promises that have been hyped as a blockchain. There are already others that are at work trying to improve or offer alternative to blockchain in the hope of a practical enterprise application that can immediately be put to work to achieve decentralized transactions through consensus theory. One such model is Hashgraph. Problem with Hashgraph though being licensed to one company as a closed source. Hopefully soon it will be an open source or others will come up with similar improved technology making blockchain obsolete. Hashgraph is capable of 250000 transactions per sec, vs. blockchain of 7 transactions per second. Further it is cheaper and will not consume the massive energy blockchain requires.
Hi Matt, First of all great videos, in my opinion best one on Blockchain and Bitcoin on the internet. I have a doubt. > What happens if a miner add a fake transaction himself into the list of transaction , after that he do all the steps of block creation and found the random number.Then he will send this block (which actually contains a fake transaction added by him) to all other nodes. How will the other nodes which are receiving this block can validate it, because no node is guaranteed to know about every transaction in the network, so they can’t check whether all the transactions included in the block they just got are valid or not.Then how can a node verify that all the transactions included in the block just received are Valid?
