UBS has spoken further about the way in which it intends to utilise the technology , and has indicated that it views its authorised ledgers as being more useful for its purposes than the permissionless version . This is a somewhat controversial position , as several blockchain experts and companies have said that they do not think a permissioned ledger is viable , and will have major technological deficiencies . It is also controversial since permissioned ledgers allow banks , and notably , regulators , to insert points of control in the system ; while this compromises the integrity of the system 's infrastructure , it does help to police the system . Purely from a capitalisation point of view multi-asset chains facilitate far greater efficiencies. This is a point made by UBS , which said that " having a permission chain gives you easier access into the legal and regulatory framework . "
