Can we use ATTiny 85 for boot loading

Atmega8 can be used for boot loading another chip by making USBASP programmer using Atmega8. Can we make USBASP programer using ATTINY85 chip? I guess flash is not a constraint. Any other constaraints?

Had you took a look at the data sheet?

The attiny85 only has 8 Pins. No place for a Crystal for correct USB communication timings. It also has no SPI but a very limited USI interface.

Buying the right controller would be much easier than redevelopping USBASP hard/firmware to use an tiny85
