what would happen

[Intrepidity]

if someone generated 1000 transactions every minute at zero fee.
Would it mean that anyone else who tried no fee  bitcoin would have very little chance of getting confirmed?

The chance of such transactions getting confirmed is very low of less than 1% Earlier when the network isn't that congested there were transactions that gets confirmed after a long time when no fee is provided. Now the miners just reject the transaction, so no transaction is being confirmed without fee. Even the fee provided based on the transaction volume is getting stuck to the network out of congestion.

The transaction getting confirmed is upon the miners, they won't be getting anything out of the transaction. Maybe if you're lucky some might do it. The chance of a transaction to get confirmed without fee in the past was found to take place between 1-7 days.

essentially you are explaining how the spam attacks work but not necessarily at zero fees and the spam attack affects the attacker too because the blocks aren't empty and virtually no node accepts zero fee transactions in their mempool.

what happens in reality is closer to this: there are some transactions in mempool already paying low fees such as 1 and 2 sat/vbyte. when the attacker starts they have to pay higher or the same to have their transactions fill the blocks and prevent others from being confirmed. but that also means others start paying higher and the fee market starts. eventually the attacker themselves end up having to pay higher and higher fees and since they are making a huge number of them the cost of the attack keeps growing to the point where it starts becoming infeasible.

I guess so. Those transactions will be dropped from the mempool unless the sender increases the fee or use other methods mentioned in this topic https://bitcointalk.org/index.php?topic=1802212.0

In my opinion, if the transaction is free, the possibility of having free Bitcoin will be confirmed, but to confirm it will take a very long time for your transaction to be confirmed by the miner, because when you make a transaction without fees and Someone also makes transactions without fees and there will be a buildup of Blocks , so it is very difficult if the transaction is free, because miners do not get anything if the transaction is free and there will be lots of stuck transactions and piling up there.

I think to attract the investors free from transactions fee.it would be harmful for us.because lot of people caught by scammers due to greediness.so they get loss.if any exchange transactions with little fee,then l can say we are safe.its my opinion. Maybe lot of  investors are not think my feelings.

There is a chance but the mempool just hold all of the transaction, of course, the miners will not accept those immediately because there is no transaction fee.
AFAIK the minimum transaction fee today can be 1 sat/byte and it depends on how many transactions are still unconfirmed. Unless they will increase the transaction fee.

I think it's better if we are still include the transaction fee don't get greedy pay the miners too.

[taufik0911]

I think nothing will happen and it has no effect on the block because the possibility of a transaction with 0 fees or gas will not be considered by blockchains or ignored
have you ever tried it? I think the minimum gas is 1 satoshi and we cannot input 0 satoshi for transaction gas

The transaction will not be executed which means it will be dropped from the network because it need to be confirm by paying a miner fee to get excuted.

No fees No transaction because miners will surely reject it and your transaction will always failed. It is like a car with out a gas it will not run. Every transaction in blockchain need gas fee or transaction fee to become successful. Even you have a very low transaction fee it will also rejected by the miners because I already tried it many times. How much more if you send transaction with Zero fee. You need to fee an exact amount to miners in order your transaction to be confirmed.

Actually it's not possible one from my knowledge.The transaction of bitcoin is confirmed through of blocks and mining.If the transaction is became free,who will do of mining activity.Then overload of transaction happened ,some miners will quit of free mining.This leads to the overload and the time of each transaction of bitcoin will increased to 3-4 per transaction.

It will just pile up in the mempool until some miners decide to include it within their block. We have had cases wherein the mempool reached insane heights, or sat/byte values that even 100 sat/byte transactions were utterly rejected to make way for those higher fee transactions in the network, and that is during the 2017 bull run. There's nothing really magical on having 1000s of these transactions being done in a single minute, though the numbers would pile up on the mempool and the miners would have to clear it at some point.

No transaction fees, no confirmation. Bitcoin transactions have been charged since 2016 when bitcoin was more difficult to mine.
Technological innovation for bitcoin is a great idea but unlikely to happen in the short term because Bitcoin is currently being decided by two teams, Bitcoin Core and Bitcoin Minner. Miners will not accept the complete elimination of the fee mechanism to make bitcoin transact for free on another system.

If somebody would indeed spam the network with 1000 transactions a minute, even if they are not zero or near-zero fees they will have no chance of getting confirmed except maybe for the first ones, ever. The mempool nodes have is not unlimited, most nodes have the default limitations at 300MB so once transactions exceed that, the ones with lower fee will be simply dropped if an avalanche of 60k tx per hour or 1,5 mils a day hits the mempool so .....nothing happens! 

But, why do something like the OP is thinking of in the first place, I see nothing to gain from it. If you want to hurt the network spam it with 100sat/b fee...if you can afford that for more than 2-3 days!
