[[dido:public:ra:1.2_views:2_tech_views:2-nodenet:3_nodearch:3_xdata| return to Ancillary Data ]]

There are different ways ancillary data can be transformed. If the ancillary data is implemented as another “[[dido:public:ra:xapend:xapend.a_glossary:b:blockchain|blockchain]]” DIDO, then the ancillary data is stored within another, parallel [[dido:public:ra:xapend:xapend.a_glossary:l:ledger|ledger]] and then, naturally, the transforms would be accomplished using that ledger stack’s transactions.

However, another mechanism available to transform the ancillary data is [[dido:public:ra:xapend:xapend.a_glossary:o:ot| operational transformation (OT)]]. These are similar to transactions but there can be multiple changes made to the data at the same time by multiple parties. Ancillary data using operational transforms is not necessarily [[dido:public:ra:xapend:xapend.a_glossary:i:immutable|immutable]].
