In such a situation, there will (temporarily) be two valid versions of the blockchain. As soon as another block is appended to one of the two, that chain will be valid while the other block will be dropped and its transactions returned to the mempool, seeing as the network always selects the longest existing blockchain.
-
A stale block, also known as orphaned block, is the one which is dropped when two blockchains temporarily coexist after two miners have solved a block at the same time, while the other one gets selected by because a new block has been appended to it (as the network has a preference for the longest existing chain).
-
Stale blocks occur after two miners have solved a block at the same time, leading to a temporary coexistence of two valid blockchains. One of the two new blocks will become a stale block once a miner appends a new block to the other one.
-
It is advisable to wait for multiple confirmations (best practice: six blocks) to ensure that the block containing your transaction isnāt dropped.

Both are valid and start spreading the new blockchain. Then there will be another miner who then appends a block to one of these two versions of the blockchain making that blockchain longer and more difficult and therefore the network chooses that one. The other one that didnāt get chosen ceases to exit and the TXs in the block are returned back to the mempool.
-
Stale blocks are these blocks that were in a blockchain at one time but then got dropped because there is another version of the blockchain which is longer.
-
First there needs to be 2 miners that both produce a block at the same time far from each other. Then they start spreading the new blockchain to the nodes around them until one of the blockchains becomes longer/more difficult and the longest/most difficult blockchain is always chosen by the network.
-
To prevent stale blocks from happening, 10 minutes almost guarantees that everything is synced before the next block.

When two miners solve a block at the same time in the Bitcoin network, the block on the longest chain is accepted while the other is dropped as a stale or orphaned block and returned to the Mempool.
-
A Stale block is a block that was in the blockchain but got dropped because it was not in the longest chain.
-
Stale blocks occur when enough time is not given for transactions to be fully confirmed or propagated throughout the nodes.(ie wait for at least six confirmations)
-
It is important to wait for more than one block to be confirmed when sending or receiving a transaction to reduce the odds of producing a stale or orphaned block.

- What happens in the bitcoin network when two miners solve a block at the same time? The shortest will be dropped
- What is a stale block? Its the orphaned block that was approved at one time but with the shortest version of the truth because another was approved
- How do stale blocks occur? two versions were approved at one time. The shorter version gets dropped.
- Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction? To avoid being dropped from the chain -stale blocks-must go through the entire internet .Wait six confirmations- 10 min

What happens in the bitcoin network when two miners solve a block at the same time?
The two blockchains go into competition. The first block to be mined on top of one of the two competing chains determines which chain is considered valid. -
What is a stale block?
A stale block is the competing block that loses out in the competition for chain validity. Any Txs that the stale block contains that didnāt make it into the competing blocks get returned to mempool. -
How do stale blocks occur?
They occur by one of the two competing blocks losing the competition for official validity. -
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
Because thereās always a chance oneās transaction could become a unique entry in an orphaned block and get tossed back into mempool for a time.

When two miners solve a block at the same time, the network must wait until a another block is added to one of the blocks. It essentially becomes a matter of the longest chain. If both blacks A and B are created at the same time, whichever one has a block added to it afterwards continues the blockchain. The block that does not continue becomes invalidated and all the transactions are added back to the mempool.
-
A stale block is a block that was created at the same time as another block but the other block had a continuing block added to it first. The longest chain becomes accepted by all nodes creating the stale block. The stale block then is disbanded and all transactions are returned to the mempool.
-
They occur when difficulty may be too low and two different blocks are created at the same time.
-
You wait for more than one confirmation so that you ensure that your transaction was not confirmed in a stale block.

- You have two different blocks that are broadcast out to the different nodes on the network.
- A block that is proven to be correct but is not used by other miners to continue the block chain.
- When two different blocks are created at the same time but in different places they are propagated to the nodes/miners. If one block is picked up by the miners and used to extend extend the chain before the other one can then eventually the miners will always pick the longest blockchain and that block will become stale.
- On average it takes 6 blocks past your block to ensure your block will stay within the chain. That is why you wait, to ensure your block is picked up.

What happens in the bitcoin network when two miners solve a block at the same time?
- The blockchain which becomes longer faster will survive.
What is a stale block?
- a block who was founded but not in the longest version of the lockchain.
How do stale blocks occur?
- two blocks were mined in the same time and the block which get fastest the next block will survive and the other block will deleted. This is the stale block.

- In this way you can be very sure that your transaction was not in a stale block.

- they compete to get it on the blockchain.
2.A valid block that is dropped.
3.when a miner gets the block on the blockchain, and a third miner use that blockchain to add more blocks, then the network will choose the longer blockchain, considering the one that has higher difficulty in mining blocks. if its not your block that is chosen, itās a stale block, and TXs go back to mempool.
4.the longest blockchain is the one considered as truth, so if your TX is in many blocks, around 6 confirmation, then your TX is pretty sure to be written on global blockchain.

What happens in the bitcoin network when two miners solve a block at the same time?
If both miners solve a block, they will be in a competition to see which chain the network will validate. If other miners add blocks to one chain making it longer, the network will validate this chain.
What is a stale block?
Itās a block that was validated by some nodes but was later rejected when other miners added blocks to a longer blockchain. The transactions in a stale block are returned to the mempool.
How do stale blocks occur?
When two miners confirm a block at the same time but the network decides to build on one of their chains. The unsuccessful minerās block is now invalidated.
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
It reduces the chances that your transaction will be a part of a stale block.

1 The chain with more blocks will get it, the longest one, the other one will be considered orphan, and dropped in the mempool.
2 A valid block not included in the longest chain, because with less proof of work.
3 In the case of mining at same time the same block, only the one with longest chain is confirmed, and the other get orphaned.

- The Chain will temporarily add both blocks and create a fork. only one chain can survive so the one that gets more clocks added to it survives. only one block is added every ten minutes to prevent confusion.
- The stale block is the block that falls off as a result of a temporary fork. it goes back to the mempool.
- Stale blocks are created when two miners solve blocks simultaneously.
- it is important to wait because it is a confirmation that your block is recorded in the blockchain. New blocks are added every ten minutes for this reason

What happens in the bitcoin network when two miners solve a block at the same time?Actually at this time nothing happens. It is only if one of the miners starts to put information on the block and it later becomes a stale block. He should wait for confirmation of at least 6 blocks or at least 10 minutes.
What is a stale block?A block that had the proper nonces but another miner has solved the same puzzle and produces a different block.
How do stale blocks occur?
Information is put on a block that has been distributed but later another longer block makes the block invalid.
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction? Because transactions can be lost in the orphan block.

- There are 2 miners mining. There is a split, then another miner comes along and picks up one of the choices. Thus the block chosen by the third miner, if it has proof of work will be added into the blockchain along with the chosen block the third miner mined.
- A stale block is the block the third miner didnāt choose. This block is dropped and once it is dropped it is referred to as,āstale.ā
- The third miner, previously mentioned did not choose the now stale block before choosing the block he had chosen, possibly due to where he was in the world because the stale block is chopped once there is a temporary split if the third miner does not base his work off of this miners hash.
- Your transaction will be sent to a miner who uses your transaction in his block, when your block is accepted into the network, you will have to wait until other blocks are added to your block, once this happens, your transaction will be accepted. This takes approximately 10 minutes.
