Testnet Staking Rewards Program

To help achieve our goal of a fully decentralized and scaled blockchain, we designed a staking rewards program during the testnet phase.

People that consistently run a node and produce blocks will be rewarded mainnet Massa tokens when mainnet launches.

Staking is what improves the security of the network. By buying rolls (freezing your coins) and producing your share of the blocks, you help honest nodes collectively protect against potential attackers, who must not reach 51% of the block production. On mainnet, staking is incentivized through block rewards: for each block produced, you get some Massa. On testnet however, you get testnet Massa which has no value, this is why we will reward you with mainnet Massa for learning to set up your node and stake right now, which also helps us improve the staking user experience.

On July 16th we launched the first public version of Massa, the first testnet. More than 350 nodes were connected at the same time after one week, which overloaded our bootstrap nodes which were the only nodes accepting connections. By setting your node up to be routable (with a public IP), you become a real peer in the peer-to-peer network: you not only connect to existing routable nodes, but you offer other people the possibility to access the network through your connection. We will therefore also reward how often your node is publicly accessible.


We have release cycles of 1 month each, called “episodes”, the first one started in August 2021. At the beginning of an episode, participants have a few days to set up their nodes with the newest version before scoring starts, but it’s also possible to join anytime during the episode.

Throughout the episode, you can ask for coins in the Discord faucet (on channel testnet-faucet). No need to abuse the faucet, we don’t reward you based on the number of rolls.

At the end of an episode, all nodes stop by themselves and become useless/unusable. Participants have to download and launch the new version for the next episode. Make sure you keep the same node private key and wallet!

Scoring Formula

The score of a node for a given episode was the following until episode 7:

Score = 50 * (active_cycles / nb_cycles) * (produced_blocks / selected_slots) + 50 * (routable_cycles / nb_cycles) + 20 * total_maxim_factor / nb_cycles

From episode 8, the scoring formula is now:

Score = 50 * (produced_blocks / selected_slots) * (active_cycles + routable_cycles + total_maxim_factor) / nb_cycles
  • 50 points of the score are based on staking:
    • (active_cycles / nb_cycles ) * (produced_blocks / selected_slots)
      • active_cycles is the number of cycles in the episode during which the address had active rolls.
      • nb_cycles is the total number of cycles in the episode.
      • produced_blocks is the number of final blocks produced by the staker during the episode.
      • selected_slots is the number of final slots for which the staker was selected to create blocks during the episode. If selected_slots = 0, the staking score is set to 0.
      • The maximum score is supposed to be reached if, during the whole episode, the node has rolls and produces all blocks when it is selected to.
  • 50 points of the score are based on the routability of the node: how often the node can be reached by other nodes.
    • routable_cycles / nb_cycles
      • routable_cycles is the number of connection trials that resulted in a successful connection.
      • Maximum score is achieved if the node can always be reached by other nodes.
  • 50 points of the score incentivize node diversity: the network is more decentralized if nodes are spread across countries and providers than if they are all hosted at the same location/provider.
    • total_maxim_factor / nb_cycles
      • total_maxim_factor is the total amount of maxim_factor accumulated at each cycle. The maxim_factor is a value between 0 and 1 representing the distance between this node’s IP address and the IP addresses of other nodes in a given cycle.
      • Maximum score is reached when running the node at home or with a provider that is not used to run other Massa nodes.

We encourage every person to run only one node. Running multiple nodes with the same staking keys will result in roll slashing in the future. Running multiple nodes with the same node_privkey.key also reduces network health and will be a point of attention for rewards.


To validate your participation in the testnet staking reward program, you have to register with your Discord account. Write something in the testnet-rewards-registration channel of our Discord and our bot will DM you instructions.

From scores to rewards

The launch of mainnet is planned for 2022.

By mainnet launch, people will be able to claim their rewards through a KYC process (most likely including video/liveness) to ensure that the same people don’t do multiple claims, and comply with KYC/AML laws.

The testnet score of a person will be the sum of all their episode scores.

The mainnet reward will depend on the testnet score. More info on mainnet rewards will come later.
