Blockchains suffer from scaling issues. This is due to the fact that every transaction has to be propagated to all the nodes in the network and after propagation is complete the mining activity to create a block and provide a confirmation. In bitcoin blockchain a confirmation can take about ten minutes. When it comes to the security of a blockchain the number of nodes is directly related to the security of the blockchain, more nodes mean better security. Whereas the performance is indirectly proportional whereby as the number of nodes increases the blockchain starts to slow down as the transactions need to be propagated to more nodes. Transactions Per Second (TPS) for some blockchains are: • Bitcoin Blockchain processes 7 TPS • Ethereum processes 13TPS • Ripple processes 1500 TPS • Visa processes 1700 TPS, if required the system can process up to 56000 TPS

Today I will be talking about Hedera, Smart cities, Artificial Intelligence, and how blockchains are being proposed as a solution without really understanding the requirements.

In this brief introduction to self sovereign identity, we will talk about how we build identity systems to create trust. Trust was something that was local and useful for establishing trust in a single domain. The only issue with existing identity systems is that they are not trust worthy. Still there is no good way to prove that you are a certain age, you have an account with a certain bank, etc. It is very difficult for someone else to vouch for you. Initially identity was siloed, then came federated identity, and now it is time for user centric identity, this is what self-sovereign identity is.

GDPR(General Data Protection Regulation) impacts on service providers seems to be a very popular topic. I have published two shows, one explains What is GDPR? and the other about Privacy By Design principles. The idea behind this series is to bring awareness about GDPR and this show focuses on service providers, as they seem to be very confused when it comes to GDPR compliance.  They are getting questions from their customers and are not sure how to respond.

Two weeks ago the show was about Blockchain Security, this week I will be talking about various tools available for some blockchain platforms. Basic blockchain architecture as it pertains to block creation and consensus mechanisms is very sound. The algorithms used to accomplish the cryptographic functions might be questionable. Hence special consideration should be given to key management, key length, hashing algorithms, and the environment that activity is conducted in. To date none of the block chains have been hacked or maliciously modified, hence from that aspect we are safe. If you consider blockchain mechanisms to be the foundation, which are unhackable at this point, the next few layers above is where the problems start.

Although crypto currencies are all the rage these days, one of the issues they all share is the stability. Where fiat currencies vary by a few percentage, the variations for crypto currencies can be quite very large make them very unstable from monetary perspective. Just like the issue of privacy & fungibility is being addressed by privacy coins, stable coins are trying to address the issue of stability. In this show I provide an overview and my thoughts.

2017 was the year of blockchain, the crypto currencies craze took over the world like a storm. Is all that glitters really gold, or just a hype. Sharing my thoughts on the security aspects of blockchain and how to address them. Show notes can be found here: https://wp.me/p8fC61-B2
