It’s a layer 2 world, and Ethereum is almost living in it

When Ethereum scaling? According to Vitalik Buterin, it might already be here. 

The nomadic creator of Ethereum tweeted today that the blockchain network’s “layer 2 strategy has basically succeeded.” 

The Ethereum network’s lead developers have had an eye on increasing throughput for the network since before the dawn of CryptoKitties, ERC20-based digital collectibles whose popularity clogged the network in late 2017.

A January 2018 Ethereum Foundation blog post from Buterin identified the problem: “Blockchain scalability is difficult primarily because a typical blockchain design requires every node in the network to process every transaction, which limits the transaction processing capacity of the entire system to the capacity of a single node.”

In that same post, he identified two strategies for scaling: sharding, which allows transactions to go through without every node process each whole transaction, and so-called “layer 2 protocols” in which transactions are made off…
