Arrangement of blockchains with a restricted transaction

A blockchain system configured to distribute simultaneously at least one public transaction and at least one restricted transaction, wherein the blockchain system includes:

• a telecommunications network;
• a plurality of proposing participant computer nodes;
• a plurality of destination participant computer nodes;
• and
• a plurality of receiving validator computer nodes;
• said plurality of proposing participant computer nodes, said plurality of destination participant computer nodes and said plurality of receiving validator computer nodes being connected by said telecommunications network, wherein
• a proposing participant computer node Np selected from said plurality of proposing participant computer nodes is configured to send a tx information transaction record's contents to all the receiving validator computer nodes forming the plurality of receiving validator computer nodes together with an identifier of a particular preconfigured privacy group;
• the tx information transaction record is encrypted by the proposing participant computer node Np selected from said plurality proposing participant computer nodes to form an encrypted data block;
• the plurality of receiving validator computer nodes are configured to add to a blockchain the tx information transaction record encrypted by means of a new tx′ encryption information transaction to form an encrypted and marked data block to provide a new tx′ information transaction which is forced to maintain a hash identifier which is the same as the tx information transaction record;
• the plurality of receiving validator computer nodes are configured to mark the encrypted data block with at least one restricted tx information transaction, such that only the plurality of destination participating computer nodes that have an encrypted privacy key are configured to read and execute the restricted tx information transaction;
• the plurality of receiving validator computer nodes are configured to assemble the encrypted and marked data block to the blockchain to distribute the encrypted and marked data block to the plurality of destination participating computer nodes in the particular preconfigured privacy group of the restricted tx information transaction, the encrypted privacy key is shared by the particular preconfigured privacy group;
• the plurality of receiving validator computer nodes are configured to distribute to the plurality of destination participating computer nodes in the particular preconfigured privacy group of the restricted tx information transaction that the restricted tx information transaction is intended for the particular preconfigured privacy group;
• and
• the plurality of receiving validator computer nodes are configured to distribute to the plurality of destination participating computer nodes the blockchain comprising the data block with encrypted and marked records wherein the blockchain comprising the encrypted and marked data block with encrypted and marked records, consists of up to N transactions and said restricted tx information transaction.
