System contracts for verification of group transactions are registered in Horizon.
Creating a new system group - https://ankhorizon.com/transaction/febc776e-6bdd-4f56-b04a-a141dc6d6a63
Group changes verification - https://ankhorizon.com/transaction/f343483d-2c02-4962-b9fd-5734b55b6ddd
For the possibility of using new methods, the contract of transaction parameters was also updated - https:/ /ankhorizon.com/transaction/6445a9ec- 8914-4 db8-b53c-5aead6978a8c.
These methods have already been implemented and are used in the National System "Territory", where the group of the official community of the system has successfully passed verification.
All group transactions are public and available in the Horizon Operations Monitor. https://ankhorizon.com/transactions
When executing contracts, the initial transaction data are not used or transmitted, but only the results of hashing work data.
Verification of the creation of a new group or changes in groups is carried out only after successful authentication of the author of the request, ( https://t.me/horizon_rus/37),
These methods are universal and can be used in any client solutions using Horizon security.
