In the design of SPoS, there are 60 minting slots in total. Currently only 15 minting slots are opened for contention. With few number of supernodes seems violate the original aim of SPoS.
This is how written in the SPoS whitepaper.
Equal minting right of the minting slots gives the supernodes equal standing and minting output in
the network. This is in contrast to Bitcoin’s mining design where there is no built-in mechanism to deter the formation of monopoly in the mining pool market, which has been shown to be a practical threat to the decentralization goal of the system.
Although not all mining power is centralized in 4 mining pools, all stakes are now centralized in the 15 supernodes.
I understand that the activities on the mainnet is not high enough to have such throughput but if we don’t have enough supernodes to understand the protocol and contribute, I’m afraid we will not have enough activities in a near future. This is what I see on Tezos and Cosmos Hub. Bakers on Tezos and Validators on Cosmos Hub understand the protocol well and they are willing to build apps and tools for the consumers to interact with the network. They earn reputation by doing so and attract their followers to stake and use the network. What I see on V currently is lacking chances for more validators to run supernodes. So I have the following questions.
- When those remaining 45 minting slots be opened?
- In the original design, there are 60 minting slots 1 second block time. Can we have 120 slots and keep 1 second block time?
- The minting slot now rely on NTP. Will the minting slot schedule be altered if the block producer change the local clock? Will this be a security issue when we have more supernodes?
