 DLT Introduction & Benefits
 
 
DLT:
Rapid propagation of information in a multi-party network
Distributed and synchronous at all times
Utilizes consensus mechanisms for synchronism
Data exchanged is 
not necessarily valid
 
Blockchain:
A type of data structure that 
supplements
 DLT
Data are packaged to blocks that form a digital chain
Cryptographic & algorithmic methods are used for immutability and identification of actors

DLT Introduction & Benefits
 
 
Potential Benefits:
Establishment of a trustless network of verifiable information exchange
Full immutable record of all actions within the network
Operation of traditionally centralized procedures in a distributed manner
Combination of multiple technology stacks under a single umbrella
 
Potential Negatives:
Heavily misunderstood technology
Primarily associated with cryptocurrencies
Might possess costly operational overhead in situations it is not suited for

 Reference IoT Scenario
 
 
Use Case: 
Manufacturing Plant
Industry 4.0 stage with the usage of IoT
Predictive maintenance by data analytics and machine learning
Reduced operational cost due to properly allocated resources for maintenance
Increased revenue due to higher efficacy of manufacturing tools
Increased customer satisfaction as a result of faster demand fulfillment times
Reduced risk thanks to stricter operational compliancy
Correct Operation? Bona Fide Data? Malicious Devices?
All the above can lead to the exact opposite of the aforementioned benefits

Slide Note

Hello everyone, my name is Alexander Papageorgiou and I am here on behalf of Inlecom Systems UK. Today I am set to talk about blockchain and distributed ledger technologies. Most people tend to focus on the theoretical aspect and benefits of blockchain technology, with whom I tend to agree with as the blockchain space has and is constantly evolving along with the areas it wishes to be applied to, such as Industrial IoT in our case. However, I would like to take a more practical approach to how blockchain could actually be applied to existing industrial IoT and providing actual value during the process.
