Blockchain for Telecom

"The future is decentralized"

I attended a webinar arranged by 6Gworld (About — Future Network Infrastructure — Who Pays and How?). This was the statement from Ernets Worthman when I asked how they see the role of Blockchain or DLT in 6G networks.

If you don’t know about Distributed Ledger Technologies, aka DLT. Here is the definition from r3 on Blockchain/DLT101:

“DLT is a decentralized database managed by multiple participants across multiple nodes. Blockchain is a type of DLT where transactions are recorded with an immutable cryptographic signature called a hash. The transactions are then grouped in blocks. Each new block includes a hash of the previous one, chaining them together, hence why distributed ledgers are often called blockchains.”

So one thing is clear: blockchain will play a part in the coming years since investments are coming in. A quick google search will give you the use-cases currently being considered by telecoms.

However, lately, I have been asking which blockchain we will be using in Telecom? We have different types, public, private, hybrid, and consortium.

They all come with their own pros and cons. For example, Ethereum is good for some use cases where it requires full transparency.

 

On the other, Telecom Archive, by Hyperledger, shows numerous cases as well.

However, new blockchains are entering the space, such as Polkadot or Solana, just to name a few. So let’s see which blockchain is more adapted in the telecom sector.

We can conclude the discussion with that it depends. We can’t really say that public blockchain is the only way to go or private. This is a question that we will have to ask ourselves while choosing the blockchain for our use case.
