Abstract: Apparatus, method, computer program product and computer readable medium are disclosed for trusted computing. A method includes, at an isolated processor including a trusted execution environment and an isolated storage, receiving data encrypted with a first public key; decrypting the encrypted data with a first private key; performing calculation on the decrypted data by using an approved program; and providing the calculation result, wherein the approved program is authorized by a smart contract, a unique identifier of the smart contract is stored in the isolated processor, both the approved program and the isolated processor are verified by at least one participant of the smart contract, and the first public key and the first private key are generated by the isolated processor.

Abstract: According to an example aspect of the present invention, there is provided a method, comprising: receiving an input ordered set of transactions after a genesis block or a preceding compressed block in a chain of blocks, generating a compressed block on the basis of the input ordered set of transactions, wherein processing of the compressed block results to an equivalent final state as processing of the input ordered set of transactions, and providing the compressed block to a distributed network for establishing a new chain epoch and replacing a set of uncompressed blocks associated with the input ordered set of transactions.

Abstract: A computer-implemented method for secure de-centralized domain name system, the method comprising: recording a domain registration transaction to a blockchain, the domain registration transaction comprising a domain name, a domain primary key corresponding to a domain public key and domain certificate information for a server node; recording a domain security transaction, comprising the domain public key, to the blockchain to generate a domain name record comprising the domain name, an associated IP address, the domain public key and the domain certificate information, wherein the domain security transaction being signed using the domain primary key; transmitting, by a client node, a domain name request to a domain name node; receiving, by the client node, a domain name response from the domain name node, the domain name response comprising the domain public key, the domain certificate information and the associated IP address retrieved from the domain name record of the blockchain; and initiating a secure communication between the client node and the server node using at least one of the domain public key and the domain certificate information.
