VeChain (Vet) was born in 2017 and is very interesting because it is a blockchain with real use cases. VeChain has a dual token economy: Vet and Vtho. Vet is the governance token (DAO), while Vtho is the gas that runs the network (fee).
The blockchain is based on the Proof Of Stake, in particular on the Proof Of Authority. It is a poorly decentralized blockchain: there are about a hundred nodes. The strong point, however, is the high scalability (low fees and high speed).

DOUBLE STAKING: AUTHORITY NODES AND ECONOMIC NODES
The validation of blocks and transactions takes place with hundreds of Authority Nodes (subjected to KYC; the data, however, are not public, they are known only by the foundation). The few nodes also derive from the high thresholds to create one: at least 25 million Vet in staking plus a fairly performing hardware. Economic Nodes do not validate transactions but still have voting power (even if lower than the Authority Nodes stakers). In this case the threshold is at least 1 million Vet (you will also receive a reward in VTho, used to pay gas fees. Gas is also generated by holding the Vet token in your non-custodial wallet or if staking on some exchanges. ). All Vtho used as gas are burned. The main use of Vet is precisely the generation of the Vtho token. In my opinion it is not a big use case but the integration of this blockchain in companies leads to burn a lot of Vtho (which however has an infinite supply).

REAL USE CASES
The blockchain is active in the sectors:
-logistics
-Internet Of Things (IoT)
-identity of the data
-authenticity of the data
-supply chain (monitoring and assembly of a specific object)
-tracking of goods (price of a certain lot and quality through a unique ID that can be scanned with a QR Code)

For example, a sensor communicates with the VeChain blockchain and transmits the data of a transaction. The use cases are real as the blockchain is embedded in many companies.
How is it used?
-food and beverages (traceability of alcohol, provenance and certifications. This feature is mainly active in China for tracking animal food: biosecurity. It provides data on ingredients)
-anti-counterfeiting (luxury and cars)
-health (Covid vaccines and Green Pass: integrity and authenticity of data saved on blockchain)
-NFT and gaming
-software integrations (Oracle, logistics, etc)
-toolchain (tool for the simple integration of Vechain in companies)

WHO BURNS THE MOST GAS FEE?
Among the major users of this blockchain we find:
-Walmart China (logistics)
-DNV GL (Risk Management who designed My Story for tracking Italian wines)
-VulcanVerse (gaming and NFT)
-DigitCardKey (verification of authenticity of collections)
-IDante (who developed the E-Hcert app relating to Covid19. It is active in Cyprus and is useful for showing the health status of an individual, tracking the polymerase chain reaction in real time, testing for antibodies and green pass. The data is saved on the VeChain blockchain and then shown on the app)

-Shopping.io (has incorporated Vet as a means of payment and in some countries it is possible to pay directly with the Vet token on Amazon, eBay, Walmart and Etsy)

DTL AND IOT
VeChain has shown that the combination of DLT (Distribuitd Ledger Technology) and IoT (Internet Of Things) works well. For example, developers used DLT to improve product lifecycle management and supply chain protocols.
DLT enables the secure operation of a decentralized digital database. Distributed networks eliminate the need for a central authority to control counterfeiting of objects. DLT allows you to store all information securely using encryption. The merger of DLT and IoT has allowed companies to merge centralization and decentralization, thus providing users with transfer speeds, transparent information and high quality. In some ways, VeChain technology can be compared with SAAS software (Cloud-based apps).

Ultimately I believe that it is a blockchain different from the others and perhaps the first one that sought to be incorporated with reality. However, I think they could have given greater importance to the Vet token which does not have a tokenomics that incentivizes holding (apart from reasons of Governance and the production of Vtho gas). I remember none of my articles are financial advice. If someone decides to invest in it, they must do their research (DYOR).
