For the baker challenges, we accept one node per contributor.

Max number of baker challenges that can be combined is OT4-B1 plus one of the others OT4-B2 or OT4-B3 or OT4-B4.

For the baker challenges, we accept one node per contributor. A contributor has the choice of submitting

• just OT4-B1 or
• OT4-B1 + only one of OT4-B2/B2/B4 or
• only one of OT4-B2/B2/B4 (In that case you would have completed OT4-B1 anyways but chose to not submit it.)

In other words, each contributor can either submit one baker challenge or max. two baker challenges, of which one is OT4-B1.
