Abstract: According to an example aspect of the present invention, there is provided an apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to compile a set of transactions in a block chain based resource management system that have taken place after the most recent block was established, establish a new block in the block chain, and in establishing the new block, for transactions associated with verification accept messages and lacking sufficient resources, cause transferring of the lacking resources from verification nodes having sent the verification accept messages.

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.

Abstract: According to an example aspect of the present invention, there is provided an apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to obtain a document, segmented into a first number of segments (510), obtain the first number of outputs of a cryptographic operation, such that for each output, a random value and a document segment are employed to generate an input to the cryptographic operation (520), build a Merkle tree based on the outputs of the cryptographic operation (530), and store a top hash of the Merkle tree in a block chain (540).
