Saulkrasti - train station in Latvia. Direct translation means “sunny shores”.

Give this country which no-one speaks about some love please.

Symbolism:
In 2024 there was a country wide scandal about “Rail Baltica” project of modernising railroad infrastructure. It appeared that unhidden corruption with clearly infeasible deliverables was put in to the budget, which ended up majority of country train stations being unreconstructed, instead of promised new in-line floors to enter trains, country-wide, citizens were forced to jump in to mud for a year, watching under-finished construction sites.

Sunny shores (Saulkrasti) network symbolises hope, that Ethereum solutions tested at this network will eventually contribute towards solving global inefficiencies and transparency in budget allocations & large scale projects delivery.
