That’s a good question. 
I was wondering that too.
- miners will keep mining until the two versions of the blockchain stop competing eachother, the longer version will be taken and the shortest chain will be returned back to the mempool
- a stale block its a block that was left out of the chain, going back to the mempool
- stale blocks occur when the miners start propagating different versions of the chain at the same time by being on actual different physical node locations.
- to ensure that our transaction is not left out on a stale block.

Both blocks get bond on the chain until another miner comblete a block. depends on wich block hes is
binding his block the longer chain will win and trop the other block with all the transactions in the
mempool. -
its a block that gets put back to the mempool.
-
they occur after a fork was resolved and a block was troped back to the mempool.
-
the rule is to wait for 6 confirmations (6 more blocks) to be sure it is validadet.

What happens in the bitcoin network when two miners solve a block at the same time?
The block forks until a subsequent block is produced based one one of those blocks. That will make one chain longer than the other fork and the most current block on the shorter fork will be dropped. The transactions in the dropped block will go back to the mempool. -
What is a stale block?
A valid block that was once on the blockchain but was dropped because it existed on a chain fork that was shorter than another version of the blockchain. -
How do stale blocks occur?
They occur because 2 nodes across the world from each other can create 2 different but equally valid blocks that get added onto the blockchain. Since there can only be one version of truth, one of the blocks will be dropped once the other block gets a new block added to it (creating a longer chain). -
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
-Because until you know that multiple blocks have been added to the chain that your transaction lives on, there is a possibility that your transaction could be dropped (by belonging to a stale block).

- When 2 miners solve block at the same time next miner will chain link with the Block with more PoW (more difficult). In case the two chains continiuew Than the longer chain will win aventually and the unaproved blocks will be back in the Mempool. They are called Stale blocks or Orphaned
- Stale Block is droped Block from the blockchain and back in the mempool.
- Stale block occure when two miners guessed the puzzle at the same time and one of the blockes gets verified and the other gets droped back in the mempool
4.Its important to waith for more than one block to be confirmed or preferably 6 just in case the block gets droped back in the mempool for verification!

1: 2 versions of the blockchain will be created and the one that has more PoW will be accepted and the other will be dropped
2: A block that has been dropped
3: When the block that made them is not accepted and another takes it’s place
4: So that your block isn’t dropped and you don’t waste time

Two versions of the blockchain are created leading to the creation of stale blocks.
- What is a stale block?
Stale blocks are blocks that are dropped out of the blockchain.
- How do stale blocks occur?
Stale blocks are the result of blocks mined too quickly or when two miners solve a block at the same time.
- Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
It reduces the risk of your transaction getting put back into the mempool(s) it came from because it’s attached to a stale block.

- What happens in the bitcoin network when two miners solve a block at the same time?
They are competing with one another to provide the longest chain to the blockchain. So, whichever miner is fastest will be able to continue on with that block, and the slowest miner will have to start over again with that block returning back to the Mempool.
- What is a stale block?
A block, which is dropped, because two miners try to work on it at the same time.
- How do stale blocks occur?
Stale or orphaned blocks occur when two minors working on a block have one block return back to the Mempool. This break-off occurs because the longest block was accepted.
- Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
6 confirmations are needed in order to confirm a block. Any less, then that block is dropped. This takes into consideration the block time ensuring the integrity of the blockchain.

A stale block is a block that was formally part of the blockchain but has been dropped and removed because it was not the longest in the chain.

stale blocks occur when two blocks are mined at the same time and are both valid. only one can win so which ever block is chosen by the next minor to build off of wins, and the other block is dropped.

a. They will both be accepted as versions of truth because they are both valid. When another block is added to one of the version of truth, only one version of the truth will be accepted and the other will be rejected and return to the mempool. -
What is a stale block?
-
Stale blocks are blocks that were not accepted into the blockchain network but no loner part of the current best blockchain because it was overridden by a longer chain (more difficult block)
-
How do stale blocks occur?
-
If two miners solve the nonce at the same time, whichever block is builded upon faster becomes the current block. The block that is no longer used becomes stale and the transactions are returned back to the mempool.

It is important to wait for up to six confirmations when sending and receiving transactions because your transaction could be in one of the blocks that could be dropped.

They both start propagating them to the nodes closest to them, there are two versions of truth until the next block is mined, once that happens, whatever block the next miner built off remains and that is the longest blockchain and the new version of truth, the other block is dropped, all the transactions from it are sent back to the mempool.
A stale block is the block that was dropped.
When two blocks are mined at the exact same time there are two versions of the blockchain. Whichever block the next miner uses to mine his block will stay, the other will become an orphan or stale block.

The blocks are added to the network at the same time and are propagated to the nodes closest to them. 2 versions of the truth now exist. When another block is propagated to one of the blocks, the other block is dropped as the longest chain is now the new version of truth. -
What is a stale block?
This is the block that was dropped and not part of the longest chain and returned to the mempool -
How do stale blocks occur?
When 2 blocks created at the same time are entered onto the network, one will be accepted as being part of the longest chain and the other will not and will end up going back to the mempool -
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
We wait for 6 confirmations before the block is accepted (Rule of six). This is to make sure that your transaction does not end up being part of a stale block and returned to the mempool.

Both blocks are valid and a version of the truth. The block that is accepted is based the block within the longest chain. The other tx’s in the rejected block will be sent to the mempool. - What is a stale block?
A stale block is a block that was a version of the truth at some point but was dropped because a different version of the truth (different block) was accepted due to it’s longer chain. - How do stale blocks occur?

Though both mines might be valid only one will be added to the blockchain, usually the longest one referring to the one with the most POW. The other will be dropped and returned to the mempool. -
What is a stale block?
It is a dropped block or a block with the shorter POW. -
How do stale blocks occur?
It occurs when two blocks were created with the same validity of truth but one is then dropped to continue the blockchain. -

To avoid the stale block from occurring.

Waiting will not prevent stale blocks. It only insures your tx is not part of it. 
Both of them are valid blocks, however, once another block is mined it will have to connect to either block 1 or block 2 out of the two blocks, the chain that will be continued is the real blockchain. The other block will become a stale block (and the transaction from that block will return to the mempool.

A block that has been dropped due to two blocks being mined at the same time and the stale blocks chain not being continued

It is important in order to make sure that the transaction will not be discontinued, because it was on a stale block. Thats why usually a transaction needs 6 confirmations to be usually considered fully validated

simultaneously mined blocks generate two different versions of the blockchain. whichever version is used as the basis to generate new blocks, will continue to be in the blockchain. the transactions of the rejected block will go back to the mempool.

- a stale block is a block that matched the block criteria but was not used to generate new blocks, as another simultaneously mined block was used to hash new blocks.

it might be that this version of the chain, that already approved your transaction, might contain a stale block, thus the transaction would go back to mempool. 6 confirmations a re recommended for a transaction to be completely verified.
