In 10 years we won’t have Blockchains

Improvements in technology may create something better that’s not a block or a chain

I think 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?

I think 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 (blockchain design, off chain, fundamental architecture)

The last one will impact how large the network can get how fast transaction times will happen, et cetera. And the structure of the blockchain is why we call it a “blockchain.” Let’s break that down.

So, what do we mean by “Blockchain?”

Let’s break out the two terms:

Block: A set of transactions connected together cryptographically into a block. So, a block is a bunch of transactions bundled together.

Chain: The blocks from an endless connected chain connected cryptographically to each other. So, this is a linear chain of blocks.

I think in the future the block will be more of a connected set of transactions (block would not be needed). And, I also think that in the future, the chain won’t be a single directional chain of blocks. I think it will look more like a mesh (or graph).

So, maybe we’ll call it a transaction graph. I’ve also seen the term “tangle” for early similar concepts. Maybe we’ll call it “the graph” much the same way we say “the cloud” today. We will all save information and transactions into this global graph (whether we know it or not).

Maybe we’ll call it “the graph” much the same way we say “the cloud” today.

The closest thing I’ve seen so far that matches my imagined path is a DAG. So, this looks very interesting to me. IOTA and Hashgraph are real-world projects that seem to be on the cutting edge of similar designs, those will be a couple projects watch as well. Let’s look at the DAG concept below.
