  Scalability is a common issue among the most used permissionless blockchains,
and several approaches have been proposed accordingly. As Ethereum is set to be
a solid foundation for a decentralized Internet web, the need for tackling
scalability issues while preserving the security of the network is an important
challenge. In order to successfully deliver effective scaling solutions,
Ethereum is on the path of a major protocol improvement called Ethereum 2.0
(Eth2), which implements sharding. As the change of consensus mechanism is an
extremely delicate matter, this improvement will be achieved through different
phases, the first of which is the implementation of the Beacon Chain. For this,
a specification has been developed and multiple groups have implemented clients
to run the new protocol. In this work, we analyse the resource usage behaviour
of different clients running as Eth2 nodes, comparing their performance and
analysing differences. Our results show multiple network perturbations and how
different clients react to it.
