I've seen proof of work,proof of stakes and proof of storage,proof of burn but have not encountered a proof of signature,can you elaborate it for us to understand it,this is something new to me and we want to explore further.
I know that you started as a proof of burn but why the change of algo,there are only one proof of burn that I know which is Barr..
Unfortunately, my English is poor. If you do not understand the answer, you can try ask again ;-) Or help the correct translation :-D
Proof of work, stake etc ... is to prevent denial of service attacks and other service abuses such as spam on the network.
The goal is the same the proof of signature too. If all nodes use the same method to generating the new blocks then does not require the effort
and all newly generated block will same. Each member of the network has a public and private key pairs.
Some members of the public key is trusted. These public keys stored in network. All trusted online node sign the accepted blocks.
The trusted keyless nodes help the transaction validation processes and preventing abuse. Untrusted nodes collect "node bounty" from trusted nodes.
If enough "node bounty" collected the reward is switched node to trustworthy.
Of course if any trusted node try abuse then the trust will revoke. The block reward and transaction fees will shared between online trusted nodes.
