The Hub, the central chain of the Cosmos ecosystem, is preparing for the anticipated Rho network upgrade that's set to launch today around 8 p.m. EST at a block height of 14,099,412.

The upgrade will bring with it a range of improvements to Cosmos' testing infrastructure, as well as the addition of what's called the "global fee" software module — an added piece of code that will allow transaction fees to be collected from users and distributed globally.

The aim is to improve the security of the Cosmos network by reducing the likelihood of validators colluding or misbehaving, the core development team at Cosmos said.
