Claim 0:
1. A node for providing a service to a client node in a network, the node comprising a hardware processor, the hardware processor being configured to:
execute a code configured to provide the service to the client node in an enclave of a trusted execution environment (TEE); and
execute a code library in the enclave to attest to the client node an identity of the service provided,
wherein the service provided to the client node is a distributed service comprising a result of a cooperation of a plurality of neighbor nodes, which are connected to the node either directly or through other intermediate nodes, and
wherein the code library is configured to attest to the client node the identity of the distributed service by calculating, when executed, a trusted distributed identity (TDID), which is an injective function of a topology and a code base of the distributed service.
