Blockchain infrastructure has evolved to encompass an ecosystem of layer-1 and layer-2 networks. In this article we’ll explore the difference between the two, and how layer-2 networks and other scaling methods like sidechains attempt to address the scalability challenges of layer-1 blockchains. What are layer-2 networks? Simply put, layer-2 networks are blockchain networks that live atop a layer-1 network such as Ethereum, with the layer-1 network providing the base layer of infrastructure and s...

Ethereum layer-2 network Scroll just launched its SCR token in a highly anticipated airdrop—but some apparent beneficiaries are bemoaning the event. The project’s first airdrop dished out 5.5% of the total SCR supply—55 million out of 1 billion tokens—to early users who had already contributed to the ecosystem, according to a blog post from the team. Of that figure, 40 million SCR was given to on-chain participants who earned 200 or more Scroll Marks—or points from using the layer-2 scaling n...
