Every civilization in RUSTORION commands a minimum set of technologies which make galactic empire possible.
Communication is virtually instanteous with any place in known universe, using cheap U-Link devices based on quantum mechanics. It's easier to establish a new link if a U-Link device can be moved physically, but establishing a duplex link using just a wide-searching and focused party is also possible.
There are points at edges of star systems that allow dramatically accelerated travel to another warp point located near another star. This travel requires opening a "breach", a shortcut between two points in space, the process of opening one includes using sensitive, expensive machinery and expending significant amount of energy and time, depending on how big breach should be and how stable. Location of stars accessible by bridge is usually not possible to assess, either because they are too far to compare with EM sensors or perhaps completely unaccessible otherwise.
A universe-wide blockchain is well established and trusted by all parties. It is impossible to control the blockchain without commanding a very high percentage of currency. However, parties voting on software and rule updates is quite common, and side chains can be established by dissenters and used separately.
Same principles that allow breaching also allow quite fast and efficient movement both in space and in atmospheres using "warp bubbles". These allow to compensate inertia and protect objects from collisions and friction during travel.
