Dagcoin drastically improves the whole DAG-chain commission payment system

A new solution for DAG-chain based cryptocurrencies has been developed by Dagcoin, which has solved the transaction fee problem faced by users. It can be both a basis for new cryptocurrencies and an addition to existing ones.

Transfers with cryptocurrency require commission payments to the owner of the platform which enables users to use the platform. Basically, it means that users would have to constantly exchange currency for the owner to enable its service. Dagcoin has made the payment of commissions of cryptocurrencies based on the DAG-chain automatic, meaning users need only keep one cryptocurrency within their wallet to exchange between currencies.

Commission fees, when exchanging cryptocurrencies, serve as protection against spam transfers and motivation for platform owners to be mindful of security. However, these can become a hindrance when the platform is used for creating new digital assets or cryptocurrency. The transfer fees are applied in the original currency of the platform and sets up major challenges for any further development.

The platforms based on the DAG-chain however considerably simplify this process, meaning not only easier access for basic users, but new opportunities for developers as well. )

While the new solution has been developed by Dagcoin, it will also be applied on another DAG-chain based currency Byteball. When comparing to blockchain, transactions within the DAG-chain are faster, with lower commission and can be done in a greater amount in a second.

The first phase of the Dagcoin development reached its final stages in late 2017, but updates and new additions are ongoing.

Dagcoin drastically improves the whole DAG-chain commission payment system

In 10 Years We Won’t Have Blockchains

I predict that in 10 years blockchain technology will improve to a level that calling it “blockchain” will no longer be a useful term.

Let’s think about this a moment. Why do we call it a blockchain? The three most interesting parts of the blockchain are:

  1. Consensus mechanisms
  2. Management mechanisms (meta-consensus of how to manage future improvements to the overall chain)
  3. The structure of the blockchain itself

The last one will affect how large the network can get, how fast transaction times will happen, and so on. And the structure of the blockchain is why we call it a “blockchain.”

So, what do we mean by “blockchain?” Let’s break out the two component terms:

Block: A bunch of transactions bundled together.

Chain: The blocks cryptographically connected in a linear fashion.

Bye-bye blocks

I think in the future the block will not be needed. In its place will be a system where transactions are linked together and can confirm previous transactions.

In order to submit your next transaction, you need to validate others in the queue. In order to get what you want (your transaction submitted), you have to do some work for others.

Why do it this way? Transaction times in this model would be faster than, for example, bitcoin’s transaction times today. The miner is technically removed and each transaction validates past transactions. Transaction times can actually go down as more people use the system.

Ciao to chains

I also think that in the future, the chain won’t be a single directional string of blocks. I think it will look more like a mesh (or graph). Maybe we could have a non-linear set of of branches that go in several different directions, where many parallel transactions are happening.

So, maybe we’ll call it a transaction graph. I’ve also seen the term Tangle (in the IOTA protocol) for early similar concepts.

Maybe we’ll call it “the graph” much the same way we speak of “the cloud” today. We will all save information and transactions into this global graph (whether we know it or not).

Enter the DAG

The closest thing I’ve seen so far that matches my imagined path is a directed acyclic graph.

What a future “blockchain” will look like.

From Wikipedia:

“In mathematics and computer science, a directed acyclic graph is a finite directed graph with no directed cycles.”

A DAG model works differently than a blockchain. A common blockchain requires miners to maintain blocks, but a DAG wouldn’t need either proof-of-work or blocks.

New models of management would be needed. So, there is a lot of work to do.

But this model theoretically gets better as new nodes are added. So it may be an improved model for both fees (or, in ethereum parlance, “gas”) and scalability over current blockchain models.

In the future, we may have something that does what a blockchain does, only better. There are still challenges to this model, so I don’t know how this will play out. But, I think this design is intriguing, and I’m curious to see how it develops.
