Supernodes

100 Supernodes form the backbone of the dHealth Network
Operate Supernode

Supernodes can be set up on-premise or on cloud services. Supernode Operators can define their own Namespace and create their own network tokens at no additional costs, have direct access to the blockchain for their applications, and possess special voting rights regarding the future development of the network.

Validator Nodes

dHealth nodes secure the dHealth Network. The nodes are spread out geographically to provide network stability. Validator Nodes operate as access nodes (API gateway). Supernodes can create custom tokens for blockchain-based applications that run on the dHealth Network at no additional costs. The primary responsibility of an API gateway is to make the data accessible in a readable format.

Harvesting Nodes

Creating new blocks is called harvesting. A Supernode that participates in the block generation process is rewarded with the transaction fees added in the block and the staking reward. The probability of an account to harvest a new block is determined by its importance. A key determinant of the importance is the DHP balance of the Harvesting Node’s account. Any dHealth Network account holding at least 2’000 DHP can delegate its balance for harvesting to improve the Node’s importance.

Consensus

dHealth Network utilizes Symbol’s Proof-of-Stake Plus mechanism. The generation of a subsequent block is stochastically assigned to a coin-holding Harvesting Node weighed by its importance. This importance is derived from the eligible network accounts’ importance that delegate harvesting to a Harvesting Node. The importance comes from a combination of factors relating to the tokens in a network account and its activity:

  • Stake: The total amount of DHP in the account.
  • Transactions: The total amount of fees paid by an account.
  • Nodes: The number of times an account is a beneficiary of a block.

For detailed information and calculation of the importance score, it is referred to Symbol’s Technical Documentation.

The dHealth Network creates one block every 30 seconds. Hence, 2’880 blocks per day and 1’051’200 every year.
