A Standard Database that can be shared across a network of sites One change done by one person at point A is instantly seen by person at point B All networks and persons can change/use said database

So basically a HA-Cluster. Hmm everything looks like it existed and got new names.

Very simply put, yes, in a certain way, I mean it's a lot of big words but shortly put, the above, the actual full explanation of what it is, would take up an A4 sheet of paper.

Distributed Ledger Technology (DLT) is a way to keep records of transactions where everyone involved has a copy of the record, instead of relying on a single central authority like a bank or government office. Here's an easy way to understand it:

Imagine a group of friends keeping track of who owes money to whom. Instead of one person being in charge of writing everything down in a single notebook (which can get lost, stolen, or altered), each friend keeps their own copy of the record. If one friend wants to add a transaction (like saying someone paid them back), they tell everyone else, and everyone updates their own notebook with the same information.

Hi Jay, we have rejected this submission as we believe it was created with AI and without any human input. Though it's a good explanation of DLT, the second point of our policy on AI content is clear about why we require human input even on AI-assisted submissions:

Even where such submissions contain useful content - as they may - to paste them verbatim into our platform may indicate a low-effort attempt to snatch bounty rewards rather than to add real value to the community. That’s not fair on those who are making an effort, and those are the people we want to encourage.

To be clear: AI cannot supply the entirety of any bounty submission. You must add your own knowledge and experience to any submission that begins as AI content. We brought this up with you two weeks ago; hopefully this second warning encourages you to reconsider how you are using generative AI on our platform.

Imagine a classic game called - Chess.

In a chess tournament, each move made by the players is observed and recorded by multiple spectators, similar to how transactions are verified and recorded on a Distributed Ledger Technology system.

Just as each spectator in the chess tournament keeps an independent record of the game, nodes in a DLT system independently maintain a copy of the ledger. This ensures that the information is accurate and consistent across all records, enhancing security and trust among participants, much like the collective oversight in a chess match ensures fairness and accuracy of the game record.

If one spectator or player decided to alter the records, others would compare their records and reject the change. Similarly, altering an older record would disrupt the sequence of turns, rendering all subsequent transactions invalid, much like in DLT systems, crypto guys call that -immutability.

Furthermore, every record (captured by a local or remote spectator, a judge, or a player) is so detailed and complete that it could allow someone to accurately recreate or replay the chess match even after a thousand years. In terms of DLT, this characteristic is referred to as traceability.

TL:DR

DLT is just another word for DRBD.

Everytime some perverts sitting in a dark room thinking about new words for existing shit. Let me groove you in.

Dedicated Servers are now

Everything is a lie. If everything happens at the exact same time, the system will fail. There is no way you save three different states if only one state is valid. If you write it on a paper it will overlap and you can´t read it.

Imagine a google document.. you write with 20 people on the same document, the same sentences, and exactly the same time typing,  but all have a different perspectives.

So you get the idea what is NOT possible.

HIGH-Availability Cluster

If we are scared in the IT world to lose something we duplicate. Is there a single point of failure we duplicate it… so we have two instead of a “single”. This is everywhere!!!!!!!!!! <- Because it is!

The Datacenter has in the best case 2 different powerlines, maybe one from the South network and the other from the north network.

The RACK which your Server is located has how much powerlines? Yes, at least 2 power lines.

How much Power Supplies does your Server have? Yes, you are right it is aswell 2.

^^ This is easy.

What do you do if you have a single Hard Drive? You duplicate…You store the same Data on both.

-> For the Nerds this the point which you build a RAID

All what you have done you replicate in another Datacenter. Why? One Server is still a single Point of Failure.

And now we dive in into low level stuff:

Distributed Replicated Block Device &/ GlusterFS

Technical:

This is existing software to have the same data”space” on two active servers. We are here on the Filesystem level… you can build up anything on top of this. Website, Forum or a Database. The data will be the same on both servers.

Noobs:

In other words due magic you have two boxes one at your home the other at your best friend. If you place something in it it will also be in the other box. If your friends remove it from the box, it won't be on your box as well.

I am sure about this? Fuck no this DRBD topic is over 20 years but i got 100% for my Final Project so maybe.

So as far as I am aware Distributed Ledger Technology, is similar to a shared digital notebook that many people can write in at the same time from different places. Everyone can see the updates, and there’s no need for a single person or group to be in charge of the whole notebook. It’s the technology behind Bitcoin and is used in many other ways where secure, transparent records are needed.

Similar to the microsoft excel spreadsheets that are used on shared drives at work basically haha! I know a little bit about crypto but id love to learn a bit more tbh

On the most fundamental level, whilst most datasets are centralised, in a single physical or digital location, DLT are designed to be spread apart, with each server taking part in this process communicating with the others to confirm information and what gets added to the dataset. These consensus algorithms as they're called allow the data to remain correct and for errors to be avoided, given how if a single node reports something the others disagree on, it can be disregarded. As such, it's inherently peer-to-peer, with no central server involved.

Blockchain and crypto are probably the most famous example of this tech. All the various clients connected to a blockchain network work together to upload that blockchain ledger, which, when combined with the strong cryptographic nature of crypto, means that malicious actions against the ledger are near impossible.
