| I'll start by saying, you've done great getting his far, if at first some of these concepts are hard to grasp, things will get better with experience as we move through the course and you're exposed to real world examples. | ||
|
|
||
| I definitely would recommend going back | ||
| and reviewing the | ||
| parts that you don't quite get and | ||
| asking questions in the [**discussions tab**](https://github.com/Cyfrin/foundry-full-course-f23/discussions) | ||
| of the GitHub repository. | ||
|
|
||
| Now | ||
| that we know all the cryptography pieces, how | ||
| the blockchain actually works, how | ||
| our signatures work and how everything | ||
| sticks together, let's talk a little bit | ||
| about how this works in actuality and | ||
| what's really going on. | ||
|
|
||
| It's important to note that many of the concepts we've covered and will cover are going to pertain to Ethereum, or the EVM ecosystem. Each specific blockchain however, may have their own nuances and intricies to watch out for. Trust that the overarching concepts will all be the same, but keep an eye out for the specific criteria that may very from chain to chain, how blocktime is handled, or which hashing algorithm is used for example. |

| ### Consensus | ||
|
|
||
| Let's talk consensus. This includes `Proof of Work` and `Proof of Stake`. You've probably heard these terms before and they're really important to how these blockchains work. |

Proof of work and stake are not consensus, they are part of consensus.
Bitcoin's consensus mechanism is nakamoto consensus, with PoW being the "Sybil resistance mechanism"
Consensus is made up of 2 components:
- Sybil resistance mechanism
- Chain selection rule
Nakamoto Consensus:
- PoW
- Longest chain rule

Ah, I see you fix it below. Nevermind.
