Consensus Protocols

Pantheon implements a number of consensus protocols:

• Ethash (Proof of Work)

• Clique (Proof of Authority)

• IBFT 2.0 (Proof of Authority)

• Quorum IBFT 1.0 (Proof of Authority)

The genesis file specifies the consensus protocol for a chain in the config property:

{
   "config": {
     ...
     "ethash": {
    
   } 
  },
  ...  
}

{
  "config": {
    ....
    "clique": {
      ... 
   }
  },
  ...
}

{
  "config": {
    ....
    "ibft2": {
      ...     
   }
  },
  ...
}

{
  "config": {
    ....
    "ibft": {
      ...     
   }
  },
  ...
}
