1/ @Solana has led crypto developer expansion through multiple market cycles.
2025 brought record onboarding, new geographic leaders, and sustained professional growth even as retention trends diverged.
Inside the data behind Solana’s developer economy 🧵
1/ @Solana schedulers all run the same protocol, but no two build blocks the same way.
Some include votes first, some pack more CU, some skip more blocks, some pay validators more. We classified all 9 schedulers across 3 axes.
Full breakdown 🧵👇
22/ Most schedulers vote within 1.02 slots.
FD Jito: BUN runs the lowest vote latency at 1.012 slots, with Agave @jito_sol and Agave @harmonic_gg close behind.
FD Jito: BAL is the slowest at 1.14 slots.
23/ Correction: the block-time numbers shown earlier were actually shred spread.
With real block-time data, only Frankendancer Harmonic BAL and Frankendancer Harmonic PRF run over 400ms.
All other schedulers, including Agave @Rakurai_io and Agave @harmonic_gg, sit below.
On @solana, execution at the scheduler level directly determines outcomes.
@syndica's latest Solana report (April ’26) focuses on transaction packing, CU composition, and block timing efficiency across the client landscape.
This is exactly where Rakurai stands out 🧵
27/ The three @harmonic_gg variants earn the most revenue per CU and per transaction on Solana.
Per CU:
• FD Harmonic: PRF 50% vs avg
• Agave Harmonic 42%
• FD Harmonic: BAL 33%
Per tx:
• FD Harmonic: PRF 58%
• FD Harmonic: BAL 33%
• Agave Harmonic 30%
