Hi all,

I've recently discovered something is quite concerning for me, i.e. with Segwit transactions single block size will rise up to 4 Mb.
This would lead to a blockchain increase up to ~200 GB/year, while a normal laptop does not have more than 500 GB.

Right now blockchain is already at 200 GB.
 
In ten years it seems quite unsustainable. Common users will cease to run a full node, only pros and geeks will do that,
and we'll never have millions of full nodes in that way.

If bitcoin is peer to peer electronic cash and want to be worldwide, IMHO more than mining centralization and price dumping
it's mass adoption of the peer-to-peer network that should be concerned.

If LN will have a great development in the following years, and I hope I will. what about reducing block size back to 1 MB or even lower?

I would like to have explanation and thoughts about a technician.

Thanks in advance.
