Conclusion

There are many more details and specific mechanisms that are not described in this short introduction, but it gives a good overview of the architecture and should help to get inside the code of the Massa Node.

Topics that were not handled here include:

• operations fees (each operation provides a fee and block factories will tend to favor operations with the highest fees for inclusion in blocks first), and how they are shared between block producers and endorsers

• ledger size limitation and the cost of storage

• slashing and node banning

• execution stack within smart contracts and what permissions smart contracts have in terms of ledger read/write access, based on their address

• details about the opcodes of the Massa WASM virtual machine

• analysis of potential attacks, like multistaking (when a block producer produces several blocks in the same slot)
