 1. Speed: Tachyon runs approximately 10 times faster than [Rapidsnark]! The [benchmark] was conducted using [sha256_512.circom] with a degree of 2¹⁶.
 2. Seamless Workflow: Tachyon doesn't require you to run any additional programs just to generate a circom proof. No need for [snarkjs] for witness file generation.
 3. Flexible Witness Handling: With Tachyon, you can modify the witness directly in your program. No need to create a separate JSON file with [snarkjs].
 4. Integrated Build System: Tachyon seamlessly integrates circom compilation into the build system, specifically bazel. When you make changes to a circom file, it's compiled accordingly and built in parallel, ensuring a safe and efficient process.
 5. Field Support: Tachyon isn't limited to bn128; it easily supports all fields!
+6. Gpu Support: Both Tachyon and [Orbiter-Finance/Rapidsnark] support MSM / NTT support using [icicle].
