101 Blockchains is hosting a free event tomorrow, Decentralising the Identity in Blockchain with TrustID.  

The event is online at 16:00 GMT (11:00 ET / 17:00 CET) and requires pre-registration - 101 blockchains event registration. .    

The event is free, but they will try to sell you their other courses and membership ["there's no such thing as a free lunch"].

How do you know that they are not stored with some sort of encryption?  Agreed it's better to use a hash function.  I'm not familiar with SAP but I'll sort of expect them to comply to some sort of security standard.

Used to develop backend smart contracts that facilitate interactions between businesses (or business units).  It is based on the internet (of value) but nothing to do with frameworks like Spring.  However, there is nothing to stop you from developing a web application alongside blockchain technology - something like Corbeans looks to offer integration.  

Funny thing is I did ask about blockchain at recent (virtual) SpringOne conference.  The question was totally ignored ;-)  
PS You know that Spring is much more than a "web application framework?"

Yeah, sorry it's Mackem.  But as you pointed out, much to their annoyance most folk in the region get called "Geordies".  Poor monkey being taken' to mackem-land and hung as it could not understand them - oh the irony ;-)

Yes, I think I can speak Geordie and also English however like most who have worked away; sounds too "posh" in the toon (Newcastle) and too "broad" everywhere else.    

Was robocop as bad as the prince of darkness?  At a local fish and chip shop; "Can I also have a tub of that guacamole [avocado dip] please?"  - "You what?... you want mushy peas?"

For some sort of clarity let me outline some of the different types of blockchain/decentralised ledger technology systems and the business case for them.  

Open or closed would describe who can view (or read) the data.  An open system would show all the data to anyone, a closed system would restrict who can see this data.
Public or private would determine who can write (or create) data.  For public this would be anyone, private systems would add restrictions.      

So an open and public systems tend to be used for cryptocurrencies that offer a store of value (bitcoin), payment services (ripple), or programmable networks (ethereum/de-fi).  Data is identified by using a public address but owned by the person who holds the private key.

A closed and private network like Corda [and Hyperledger Fabric] would require some sort of identity access management.  Typically participants only share a subset of their data with relevant customers as it may be commercially sensitive (Alice may not want Oscar to know that Bob pays less for a widget).  Trade finance, supply chain, or any system which would benefit from "trusted" shared data would be the typical use case.

An open and private system would suit the publication of laws, publicly viewable tax returns, public announcements, and similar.  Closed and public would suit voting use cases.  

...and then there are central bank digital currencies (CBDC) - but that's a whole new topic!

Hope this helps a bit, for a nontechnical introduction I'll recommend the free Enterprise Blockchains Fundamentals course from 101 Blockchains.

The thing is that particular monkey did a decent job, and got himself re-elected twice.  He did, unlike the US monkey, stop all the monkey antics (like getting drunk and thrown out of football matches) once in public office.  I believe the post was removed before he could be elected for a third term, I guess they didn't like his independent stance.  Also, folks in the UK were cooking "Bitter Orange Tart" as it was yesterdays (Jan 20th) recipe of the day - no idea why.

The guy seems to have slowed down, maybe to help others understand him better.  

It's fun being bilingual as you can quickly switch into an uncomprehensible language to confuse those (southerners) from outside the area.  Or just drop the odd native word/phrase in for a  delayed effect.  Had never heard the term "pit‑yacker" before but sort of fits with the other terms for the regions ("smoggy", "monkey hanger*", "macum", "sand dancer" etc).        

I did find that in the US they tend to think you are speaking Welsh.  

*During the Napoleonic wars, they really did hang a [poor] monkey.  More recently they elected a monkey mascot as a town mayor, then kept re-electing him.

The focus seems to be on tokenisation and finance* but it's my personal belief that it is a technology of the future with a move towards an internet of value.
However, at present, it's slow and expensive and going to face a lot of resistance from the people who have a stake in the existing technology.

The technology is already being implemented in projects like Spunta Banca in which the Italian retail banks are performing reconciliation operations.  In trade finance, there is the MarcoPolo project.  Note these applications are more in the enterprise (permissioned) ledger technology [like Corda] which is not quite the same as the more open blockchain solution technologies [like Ethereum).    

Outside of all the nonsense and "crypto" hype, the technology seems to offer a better way to facilitate business interaction either internally or externally.  Simply put its a read/write data store (ledger) in which all the systems come to an agreement (consensus) as to what is to be written as it solves an old problem of "double spending". Still, a lot of misunderstanding and general confusion as there is no real consensus around the general terms used to describe the technology.    

*Decentralised Finance (De-Fi) is one of the new buzz words.  This is opposed to the current centralised fiance (Ce-Fi)

Typically AOP addresses two concerns, namely that of Code Tangling and Code Scattering.    

They're not critical to the business

Don't be too sure. For example, its often a requirement is to log activities for security and/or audit purposes.

a new independent RHEL-clone



Rocky Linux which is to be a red hat enterprise fork by the original creator of CentOS (Gregory M. Kurtzer).  This will of course surprise nobody outside of the IBM senior management folk

An Introduction to Database Systems by Christopher J. Date.  It's a bit old now, but then so are the concepts and relational databases.  

don't mention cryptocurrencies - it ain't that  

- it is now as they announced a token called XDC.  
Also, they just announced a partnership with IBM.  That gives IBM access to the DLT technology and R3 access to more customers.

I'll still say have a browse of the Spring Documentation.  
It's always well written, accurate, and up to date.
