Definitions
- a participating node or blockchain node of the blockchain network refers to a natural or legal person that maintains, shares and operates with its own local copy of the blockchain; namely, ledger or ledger.
- the telecommunications network 14 may be a network such as a local area network, LAN, wired or wireless, wide area network, WAN, such as an intranet, an extranet or the Internet; or similar.
- the telecommunications network 14 facilitates the communications between the nodes 12, 13 of the chain block network 11.
- the message requesting the execution of the restricted transaction includes, in addition to the data of the proposed transaction, the metadata relating to the privacy context for which the restricted transaction is executed.
- the encrypted and marked data block of the block chain will be distributed by the validating nodes 13 of the block chain network and will comprise from 0 to N transactions and at least one information transaction t x '; namely, a block of data encrypted and marked as restricted. Participating nodes 12 in the privacy group of t x are further informed that t x is a transaction destined for that privacy group.
