The co-founder of the network referred to second-layer networks and generated controversy in the ecosystem.
Second layer (L2) scalability solutions on Ethereum are, for many, the future that will enable the growth of this network. Vitalik Buterin thinks so too, although he also states that L2s have "back doors" that developers could use to fix certain flaws.
Specifically, Vitalik Buterin expressed that “rollups and all the L2s that exist on Ethereum today have what I call 'training wheels', a kind of backdoors with which developers enter, save assets and change the protocol if "They see some kind of error happening."
This concept of training wheels became popular to refer to L2 projects that are still in the early stages of development, that is, below stage 2. As can be seen on the l2beat site. com, there are only a couple that don't have those training wheels, and they are not among the 20 most used.
In addition, the Russian-Canadian developer assured that he spoke with teams developing rollups and scalability solutions and commented that his intention is to "take off those safety wheels next year."
