few days back, @union_build  dropped V3.2 and with it, a major shift:

The testnet just moved from PoA to PoS.

Here’s why that’s huge:

• PoA is fast & centralized (good for early testing)
• PoS is decentralized & secure (real-world conditions)

Now, Union’s testnet is a live environment with real validators, real incentives, and real decentralization.

That means:
• Better testing
• Closer to sovereign rollups & L2s
• Clearer path to mainnet

Union just levelled up.

$U summer is in full swing
