- When 2 miners solve a block at the same time the block in the longest chain wins and the other block is discarded and considered a stale or orphaned block. All the transactions are returned to the mempool.
- Stale blocks are blocks that were in the blockchain at one time but then got dropped cause there is another version of the blockchain that is simply longer without them blocks in it. Stale blocks are sometimes also known as orphaned blocks.
- Stale blocks occur when a block was valid for a while because 2 were produced with the same version of the truth but then dropped because the blockchain continued on another block
4.The transaction could be in a stale block and 6 confirmations will ensure transaction is in a block thatâs accepted by network.

- What happens in the bitcoin network when two miners solve a block at the same time?
Both miners propagate the solved block to other nodes and miners closest to them and those nodes and miners accept those versions of truth. Now, when confronted with both versions, the original nodes will stick with their version, but this gets resolved when these versions get presented to new nodes and the community entirely. The consensus among the nodes and miners is to select the bigger block, or better put, the block witht he most proof of work and higher difficulty used to solve(lower target met). - What is a stale block?
When a block beats out another block for confirmation and acceptance to the blockchain by the bitcoin network, the rejected block gets dropped/orphaned and is sent back into the mempool. This rejected block is considered a stale block - How do stale blocks occur?
The stale blocks are the rejected blocks/transactions of the same block chain that got ousted by a stronger proof of work block on the same blockchain. - Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
To ensure this transaction is really confirmed by the whole community of nodes and that no bigger proof of work exists for those blocks.

There are temporarily 2 competing versions of the blockchain.

A stale block is one which is any that are in the chain that loses the competition between 2 competing chains that arenât in the other chain.
3.When more blocks are mined to one of the forks than the other and these are propagated across the network this will become the winning chain. Any blocks in the competing chain(s) would become stale blocks.
- Because of the chance of it being confirmed in a stale block. It would then be reset to unconfirmed.

1 What happens in the bitcoin network when two miners solve a block at the same time?
Both of them are initially accepted to the blockchain. The blockchain is split into two ends and eventually one of them is continued and other one discarded.
2 What is a stale block?
The discarded block.
3 How do stale blocks occur?
Miners solve a block at the same time, blockchain is split in two ends, other one gets validated the other gets invalidated (=stale block).
4 Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
This helps stale blocks from happening.

*** What happens in the bitcoin network when two miners solve a block at the same time?**
It causes nodes that are closest to each miner to accept that particular block as itâs version of âthe truthâ, splitting the network.
*** What is a stale block?**
A stale block is a block that had originally been appended to the Bitcoin network, but has since been rejected.
*** How do stale blocks occur?**
Stale blocks occur due to these moments where 2 miners may produce a valid block at the same time, splitting the network. Eventually however, a new miner will come along and propagate their block to whichever version of the blockchain they have. Eventually there will be a chain that is longer than the other and this is the chain that is accepted by the network, meaning all TXâs from the block on the shorter chain are returned to the mempool and those blocks are now redundant and considered âstale blocksâ.
*** Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?**
Sometimes these competitions between blocks can continue as miners try to add blocks to whichever version they have. Waiting these 6 confirmations allows the network enough time to decide on a winning chain.

1. What happens in the bitcoin network when two miners solve a block at the same time?
Both blocks will be added to the chain and propagate through the network. Some nodes will get one version and other nodes another version. The next miner that creates a block and adds it to one of the two version will make the other block to be removed as the network always choose the largest blockchain.
2. What is a stale block?
Blocks in the situation previously described which where included in the chain but then removed because the network choosed another version of the chain.
3. How do stale blocks occur?
As mentioned before, there are blocks which where mined at the same time by two different miners and where completely valid, accepted and propagated through the network. As the chain canât have two versions, when a new block is created and inserted in one of the two version the other block will be removed and is called a stale block, or orphan block.
4. Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
The best practice indicates that 6 confirmations is a good way to confirm the Tx. Is better to wait for more blocks to be added because only waiting for one block means that this one can then be removed and the Tx will go back to the mempool.

1/ Each creates a valid blockchain, but different from each other with last appended block
2/ A block from 1/ which is finally not added to definitive blockchain and poored back in mempool
3/ As soon as 2 miners solve a block at the same time, only one will be actually added to the blockchain, other block will be slated
4/ the definitive validation of transaction is achieved when block itself is definitely added to blockchain, any other orphaned block being poored back in mempool: 6 confirmations are considered to be the right number, supposed to happen in 10 minutes or less.

6 confirmations takes approximately 1 hour. Then you can be 99.99% sure that your transaction will be immutably recorded on the bitcoin blockchain forever.

What happens in the bitcoin network when two miners solve a block at the same time?
If two miners solve the same block at the same time, then two different blocks will be propagated to the network, which means not all nodes in the network will have the same chain. So it depends on the next miner on which block they will build a new block and propagate it to the network. -
What is a stale block?
A stale block is a block that gets dropped in a situation described above. So when two miners solve a block at the same time, one of them gets dropped. -
How do stale blocks occur?
They occur if two blocks are solved and sent to the network at the same time. -
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
Because if you wait for another 6 confirmations after your block the chances are that your block will not get dropped.

Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
As the occurrence of miners solving blocks at the same is regular and blocks being stale or orphaned the possibility of a transaction being confirmed first time is unlikely therefore it is recommended to wait for multiple confirmations for a transaction to complete and therefore the specific block can be propagated to the blockchain.

the block splits then when another miner tryâs to solve the nonce with one of the 2 previous miners block whoever solves the nonce first wins the blockhain. the network then accepts which of the 2 chains has the most PoW. the other miner then is rejected by the network and is returned to the mempool

Why would waiting increase the risk of stale blocks? 
- Both are considered the âtruthâ until one chain becomes longer. At that point, the âlosingâ block becomes stale and any unresolved transactions return to the mempool to be verified.
- A stale block is one that has become dormant after a âcompetition lossâ between another block. See above.
- Stale blocks occur when competing miners both solve a block concurrently and then one chain becomes the dominant chain (longer/New block addition) and is propagated throughout the network.
- To confirm the newest block has been confirmed and propagated to enough of the network to help prevent stale/orphaned blocks.

Both blockchaines get propagated. The version of the blockchain which gets added a first new block will become the only one valid.

A stale block is a valid block which had been added on a parallel blockchain before the blockchain got invalidated as the other got bigger.
-
Because two different blocks were added to a different version of blockchain at the same time. At sometime on block gets bigger and the other blockchain gets invalidated.
-
Because even though the tx had been confirmed in a block this block can possibly still become a stale block.

It ensures that your transaction is not confirmed on a stale block. Enough time is given to make sure enough blocks are safely added to the blockchain and not added at the same exact time as another block. It ensures your transaction is confirmed.

Both blocks will be propagated to the network; the nodes closest to each miner will receive information about their proximate block; the blockchain is then effectively split. The next block to be mined will be added to one or the other of the previous blocks and all the other miners will continue to mine on this longest chain.

A stale block is the block that is not accepted by the network in the above scenario.

When two miners solve a block at the same time, only one will be able to keep its place in the blockchain. The one left behind is the stale block. (Or is it âorphaned?â I prefer âstale,â âorphanedâ makes me feel sad for the block

To make sure your transaction doesnât end up in a stale block, and is actually part of a block that makes it onto the blockchain!
