Alpenglow
.@bw_solana, CEO of @anza_xyz on getting started as an engineer on Solana.
“Just start playing with stuff. On the testnet, on the mainnet. Go mint a token, go deal with moving some stuff around and making some transfers and just building some simple hello world example. Go get your hands dirty.
I think the that’s the best way to learn. That’s how the information really sticks. You can do some reading along the way to understand stuff, but just dive in.”

Important update for validator operators.
Solana mainnet validators can now register a BLS pubkey, a prerequisite for Alpenglow.
This week, a second feature gate, the Validator Admission Ticket (SIMD-0357), goes live. Once VAT activates, validators without a BLS pubkey stop participating in consensus and stop receiving inflation rewards.
