DShot is a new communication protocol between flight controller (FC) and ESC, substitute to Oneshot and Multishot. DShot stands for Digital Shot.
Advantage of DShot
Compared to Oneshot and Multishot, we are informed that DShot is better because:
*No More ESC Calibration Required (no oscillator drift)
*More Accurate ESC Signal, and more robust against electrical noise
*Higher Resolution of 2048 Steps, compared to others of 1000 steps
*Faster Than Oneshot
*Safer, every signal has cyclic redundancy check

- 1 x iPeaka EFM30A BLHeli_S D-shot 4-in-1 ESC
I'm using this ESC with the iFlight Revo Bee F4 FC and 4 x DYS Fire 2300KV motors. The 4-in-1 ESC makes for a very compact and neat setup (much better than having 4 separate ESCs). The responsiveness and power output is excellent. Would be nice if the wires came with JST-SH plugs on both ends so they can be connected directly to the FC without soldering. Also note that the 6-pin ordering shown on the image above is incorrect - it should be VSS,NC,M1,M2,M3,M4 (from left to right).
