If you could hard fork Bitcoin right now, what changes would you make?

[Leviathan.007]

I don't have any technical information regarding Bitcoin project on github, but as a normal person who use and invest on bitcoin, I would focus on transactions and I would try to make the transactions to be real fast with a very low amount of fee. Also, I would try to implant some sort of smart contracts on the network, it will allow make to create own tokens under the bitcoin's network.

I don't have any technical knowledge about what I can change with bitcoin if I do the hardfork now. But I would like to change the transaction time and Tx fee. Now If I want to do any transaction it cost me around 5-6$ to do that in normal speed. If I do with lower fees it takes too much time to confirm the transaction. So, I would definitely make it faster and easier and cheaper for users.

I don't think it is possible, but I want to add a payment revert option in the transaction before it confirmed 10 blocks. The transaction fee may not be returnable and everyone needed to wait for 10 blocks for the transaction confirmation though.
Lots of time people send BTC to the wrong address, a revert option will give them a few minutes though if they had done some mistake.

Incentivize full nodes by allotting 1% of a single block reward to the nodes that has the most uptime in a 2-week cycle. Might not be the best change to do but will certainly be an appreciated one, especially to those running nodes round-the-clock. 1% won’t hurt much on the miners really, and that 1% would be taken off of all the blocks on that two-week period, so if there are a thousand blocks more or less, each of those we would take 0.0001% to add to the pot for the nodes that stayed up non stop during that period. Not a great implementation, I know, but it’s something for the nodes.

EDIT: Pretty sure my math is off, but you get the point.

If you had consensus to make whatever changes you saw fit in Bitcoin right now with a hard fork and the community was 100% behind you, what changes would you make? What improvements do you think Bitcoin needs through a hard fork?

Would you update scaling, security, consensus protocol, programmability/smart contracts, other stuff? Give details.

security is what I will prioritize. with this hard fork, many people will struggle to get bitcoin because the profit now is very tempting. criminals against bitcoin will also increase, this security is useful to avoid negative actions that will surge during the hard fork

Then I believe Roger Ver and Jihan Wu could bribe the full nodes with an increased 5% of the block reward if they support, and run Bitcoin Unlimited. Craig Wright 10% if you run, and support his shitcoin.

If the full node gets 1%, then Roger Ver will give 5% and poach.

Now full node  has 0%. What prevents Roger Ver from giving 5% and getting his way?

I think every blockchain is aiming for faster transaction speed with low fees, If I have given the opportunity I will not do it, we have a lot of forks in the market right now like litecoin and those Bitcoincash tweens lol. Instead I will just support one of them or find another coin with almost no transaction fee which already exists there is no point in creating a redundant coin, I don't plan to add another sh*tcoin on the market. But I won't leave bitcoin it is the backbone of all altcoins.

[Lizzylove1]

The only thing I would have love to do with bitcoin network is to increase transaction time per-second. After this, many alt coins will die off BTC can just do

[Shasha80]

I think Bitcoin is good enough now, Bitcoin hard fork is not really needed. Too many hard forks already happened anyway,
better to focus on something else. But if there really has to be a change from Bitcoin, it might be about Bitcoin transaction
speed. Which is still an obstacle until now.

As seeing that the market continues to spread and additional crypto users, speed should be more prioritize this time. Fees are just a giveaway for miners and help them to grow and earn a profit. It only worsens the situation if we also cut the fees for miners and pay their services, I don't have to change it.

I can picture it out that there is a bottleneck to happen once we fully engage in Bitcoin and could be in a hassled if we keep the TX speed the same. Things we need to look at how this could be changed or we need higher specs for mining equipment but it also increases the fees.

None.
Current state of Bitcoin is perfect because its stable and that is most important.
We need more privacy but i wouldn't push it now, because privacy solution is not ready to be included in Bitcoin code.
If it will be, and will be tested to pain treshold, we will have it.
Bitcoin development way is slow, but it needs to be slow to hold value.

[Yamifoud]

Bitcoin is beautiful the way it is, except for one thing, speed. This is perhaps the single most significant drawback.
Of course, there are others, for example, a protocol that forces you to use huge computing power, but this does not spoil life as much as the speed of transaction confirmation.

Yeah, it is enough that have nothing to change. And I used to keep the feature the same as we have known and trusted upon. Speed is not resistible, anytime it changes depending on the blockchain traffic and not sure if there is a way to change it, in fact, it never been recognized as a big problem in Bitcoin but just normal issue, and I don't think there is a need to change it.
What we need now and in the future is the consistency of its security. With the increase of hacking events, it seriously affects the market trust and people will be afraid of the situation will get worse, and hacking/scamming complaints wildly spread around.

I'll make an implementation of an standalone blockchain network just like in Polkadot, where you can make your own Blockchain by hosting it. That connects into a mainnet. So basically its like the Ethereum network rinkeby, ropsten network concept. But corporations or individual could create it themselves add liquidity to it. Just think of it as an offchain like Lightning Network but with more user friendly interface.
