The reason why there only needs to be ONE blockchain money ledger is very simple.
It is a GLOBALLY DISTRIBUTED LEDGER.
It cannot transition faster to new states (clearing transactions) than the nodes can validate and propagate the transactions physically across the network. Every bit you push that upwards, you are eliminating otherwise viable network locations and hardware.
Every shitcoin project starts from the premise that shorter block times, or bigger blocks will make this structural limitation of the global state ledger model go away.
They always base their clams on simulation networks that lack the real world delays and unreliability and congestion. A protocol can work fast on loopback without actually being usable on a real network.
- Faster blocks means poorly connected nodes are excluded.
- Bigger blocks means the basic cost of running a replica of the database (eliminating the need for trust) rises rapidly beyond the majority of those who wish to's capacity to pay.
And combining the two, big, fast blocks even further narrows down the number of key network backbones that can host viable servers, from the NETWORK perspective, and the cost of such real estate tends to also be a further impediment. Rack space is some of the most expensive real estate in the world, and the fatter the trunk it's attached to, the more expensive still.
Shitcoiners literally are acting like us plebs can compete with Amazon and Google data centres on their position on the backbones.
Shitcoins that try to push these limits wind up in a situation where the possible customers are not numerous enough nor is the volume enough to sustain the network as a real global shared ledger, and so they become worthless, and eventually are abandoned. If they even had a legitimate purpose and were not just a way to hide a ponzi from the SEC.
If they even had a viable and reasonable potential userbase of profitable business operators to base the operational costs of the network on, it would still be difficult to justify using a broadcast model when multicast and and point to point connections are what you build centralised distributed systems out of.
