Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Does the lightning network have "equal" qualities to the base layer of the bitcoin protocol?

For example, the bitcoin protocol when operating on the base layer has these qualities: Finality, uncensorable, unseizable, unfreezable, permissionless, borderless.
These qualities are what make bitcoin, bitcoin.
Does using lightning network encompass all of these same qualities?
If not, what are the trade offs?
Is there a good reading, video, or podcast that covers this specific question with more depth?

Is there an in-depth place with full documentation of the entire bitcoin protocol and client specifications?

I’m working to create a clone mostly just to learn about blockchain and I had a few questions about how consensus is made about what transactions should be in the next block and how people efficiently share node IP addresses in a decentralized way.
If anyone has the answers to any of these it would be really great and if not I’m willing to read some documentation. Thanks!

The USD system incentivizes people to cut corners, cheat, and be dishonest. The Bitcoin protocol incentivizes honesty, proof of work, and disincentivizes cheating. Bitcoin's security is stable, predictable, and backed by voluntary association. The USD's security is backed by government force.

Is there a python (or other) library to send raw bitcoin protocol commands to a peer?

From the protocol docs, there are some interesting low level commands that aren't really surfaced in the client RPC API. Is there a python, ruby or nodejs library that will allow you to connect to peers and send protocol commands?
Something like:
python bitcoin_wizbang.py start python bitcoin_wizbang.py connect 88.99.167.175:18333 python bitcoin_wizbang.py send_command getheaders python bitcoin_wizbang.py stop
Thoughts?

For all the purity test haters out there, guess what! The Bitcoin protocol is a never-ending “purity test” to achieve globally distributed consensus about the number of Satoshis in every Bitcoin address around the world.

So forgive the people who apply their second layer purity tests and virtues on top of the Bitcoin blockchain. That doesn’t mean you have to agree with how they’re using Bitcoin.
It just means that there’s room for everyone to apply their own subjective beliefs and purity tests to Bitcoin, without compromising Bitcoin’s security/purity.

Question about creating 'fake'-transactions and about making changes to the Bitcoin protocol

If a miner, who added fake transactions to his/her block, finds the right nonce and broadcasts it, full nodes reject it because it doesn't match their version of the blockchain. It is therefore not added to the blockchain and the remaining miners keep working on the block.
For a miner to add fake transactions to the blockchain, his/her block has to be accepted by more than 50% of full nodes (right?). Each full node has equal voting power, regardless whether it is run on a laptop or on a super computer. Therefore, couldn't someone run a bunch of full nodes until he/she controls more than 50% of all full nodes, thereby enabling him/her to add 'fake' transactions?
So far, I thought that basically any change could be made to Bitcoin (protocol change or fake transactions) as long as more than 50% of all full nodes agree on it. After all, protocol changes are, just like fake transactions, implemented simply by changing the last block.
Apparently though, the following criteria have to be met to make protocol changes:
(link to the article: https://medium.com/@galea/bitcoin-development-who-can-change-the-core-protocol-478b8ac5fe43)
Since they are both just changes to the last block, I wonder how it comes about that for one, you need >50% consensus, while for the other, you need >=95% consensus.

Type names used in this documentation are from the C99 standard. Note: Some protocols (eg, HTTP) do not allow complex structures in GET requests. An implementation using these protocols should allow silently upgrading GET to a POST with the same semantics.

These content types may be specified in ... Bitcoin is a form of digital cash that allows online payments between the buyer and the seller. It works as a digital ledger that records transactions and balances of accounts. The takeaway here is that PoW-based blockchain protocols rely on miners who have physical rigs. This means there is an upfront cost on the miner. The miner has to spend real money (usually more than a few thousand dollars) to have any chance of winning a block reward. In the case of Bitcoin, miners can pool their power together. When miners ...
