First, I reacted sodium hypochlorite with hydrochloric acid to produce chlorine , then I added the sodium thiosulfate to the resultant solution and it gave me a white precipitate immediately.
I am guessing that chlorine was reduced to chloride and thiosulfate ion was oxidized to sulfate ion.
The sulfate ion , in turn , reacted with one other compound in the mixture ----either leftover hypochlorite , excess chloride Cl- , or sodium ion Na+ to form a white precipitate.
What was the white precipitate?

You have got it wrong. There are no such ions present which may give a white ppt.
Did you store the chlorine or allowed it to escape.
In this case the acid is reacting with hypo to precipitate whitish yellow ppt. of Sulphur.

2 NaS2O3 + Cl2 → Na2S4O6 + 2 CI−
Na2S4O6 = Sodium tertathionate ( white ppt )
and since you have water as solvent i guess it's
Na2S4O6 . 2H2O
Sodium tetrathionate dihydrate
