- The blockchain will split into two different versions which will cause the shortest chain to be dropped and then will become a stale block and transactions will return to the mempool.
- A stale block is a block that is rejected due to there being a longer version of the blockchain out there resulting in it having its transactions returned to the mempool.
- They occur when miners mine a block at the same time causing half of all the nodes getting one version of the blockchain and the other half getting the other version and this results in only one version getting accepted causing one of the blocks becoming a stale block.
- This reduces the chances of a stale block occurring.

- Stale block or Orphaned block is that block which after six conformations will be dissolved and all transactions will appear again in mempool.
- If two block are mined around same time and all network doesnât have same block but one of two.
- Because it could happened that someone can double spend or cancel transaction.
- Both blocks get accepted by the nodes, but nodes will carry both versions of truth until the next block is generated.
- A stale block is the block that is not linked to the next block generated.
- It occur when the miner that mines the next block in line selects another block.
- Because you want to make sure the blockchain is fully synchronized globally.
- What happens in the bitcoin network when two miners solve a block at the same time?
Exp. we have a miner A and miner B that are producing a block at the same time. Then we are waiting for the 3rd miner and on which block of these 2 (A and B) miners the 3rd miner continue mine then that block of miner A or B will be accepted, depending which chain is longer. The longest chain always wins. - What is a stale block?
Stale or Orphan block is a block that is returned from a blockchain in a mempool. - How do stale blocks occur?
When 2 blocks were produced at the same time and then the longer chain wins, blocks which were in a shorter chain will be moved in a mempool and these block called Stale blocks. - Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
We need to wait for a 6 confirmations because of Orphan or stale blocks. Our block could be in a shorter chain and then will be moved in a mempool.

- They will both go up and create two different blockchain, but depending on which block the next minor chooses which will then be the longest blockchain, the other block will then get dropped.
- A stale block is block that has been dropped and does not belong to the blockchain anymore.
- When to miners solve a block at the same time, they both go up on the blockchain. But only one block will get to stay depending on which will become the longest. The block that then belongs to the shortest blockchain will then become a stale block.
- So the transactions doesnât end up in a stale block

- there are two versions of the blockchain until the longest chain and highest POW difficulty wins
- Are blocks that are dropped from the chain because there is a longer chain that won. Stale blocks are technically different to Orphaned blocks but people use them interchangeably
- Stale Blocks are because there are several different versions of the blockchain depending on where the nodes are located and the speed at which miners mine a block. If the network chooses another chain over your nodes chain then the block becomes stale and returns to the mempool.
- this is to make sure there is a high probability that your transaction will be on the blockchain. The more blocks that are mined the higher the probability your transaction is permanently on the blockchain as nodes start syncing from around the world. 6 blocks approx 1hr is the industry standard to be absolutely sure your transaction is immutable.

Both blocks will be broadcast to the network, until another block is mined and added to one of the two blocks creating a longer chain and more proof of work. The other block is forgotton and dropped from the chain and all transactions in that block are returned to the mempool.

1-4. When 2 miners solve a block at the same time, the next block confirmed will determine the accepted block it used to carry on. This process can carry on until one chain wins which is why we wait for 6 confirmations. The other block will become stale and transactions will return to the mempool.

What is a stale block?
Stale Blocks are blocks that are no longer part of the current best blockchain ⌠on the longest chain, until another split on the network occurs .
- When two 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.
- A stale block is the block that was in the blockchain but then dropped because another block that was produced at the same time was part of a longer chain.
- They occur when two miners mine a valid block approximately at the same time.
- In case of the occurrence of two chains, once one chain is accepted as the main chain, the transactions of the loosing chain are returned back to the mempool.

Using an example of two minors attempting to write their block the one with a chain equal to or longer than six will be the truth and then accepted (I would assume that if they both have a chain equal to or greater than six the first in the list would be accepted). The other minors (as this example is restricted to two nodes) chain will be added back to the mempool for hashing.
It is a block that is no longer deemed truthful and therefore no further block can be written to it and will be droped and added to the mempool.
When two (or more) nodes attempt to write to the chain after having hashed their blocks at the same moment in time and before the truth has been shared to through the network.
So that part of the chain has not already been deemed as not truthful and subsequently will be dropped from the blockchain i.e. determine if it is stale or not.
What happens on the bitcoin network when two miners solve a block at the same time?
When this situation happens two valid versions of the truth are generated but the one with the longest blockchain will win, this is determined through other miners.
What is a stale block?
A block called stale or orphan is that block that is generated when there are two versions of the valid truth but it obtained the shortest chain of blocks.
How are stale blocks produced?
Stale or orphan blocks are the product of solving the problem of two miners 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 is important to wait a minimum of 6 commits for a block to avoid running into orphaned blocks to ensure that the transaction is validated and included in the blockchain

one will win eventually, the longest blockchain will win. One blockchain, the shortest will be orphaned and dropped. - What is a stale block?
orphaned block on the shortest blockchain where there has been another version of the truth that has been accepted by the decentralised nodes. - How do stale blocks occur?
by two version of the truth or blockkchains being produced or propagated in the network and maybe blocks being produced prior to the 10 mins. Blocks being produced prior to six confirmations and prior to the correct version of the truth having the chance to propagate through the network. - Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
to see if that chain has been accepted by the decentralised network. The more confirmations the longer the block-chain length. The longest block-chain is the one that is accepted as the greatest version of the truth so miners extent it more by resolve the nonce for the next block reward
Homework On Stale Blocks.
What happens in the bitcoin network when two miners solve a block at the same time?
- When two miners solve a block at the same time, this means that they solved the nonce at the same time and the hit the required target that was set by the network. Both block are subsequently added on to the blockchain.
What is a stale block & How do stale blocks occur?
2/3. When two miners mine a block at the same exact time, having both solved the same nonce reaching the target that was set by the network, now each node will send the data across the blockchain network. In turn a miner some where across the world is mining the next block on the blockchain. Depending on there node the miner would have received 1 of the two blocks as the last block of the blockchain. They would link there block that they solved on to the blockchain and in turn would now make it the longest POW on the network. The nodes on the network when receiving update of the blockchain, it would sadly be not recognised as no longer on the network and in turn called a stale block.
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
4.The relationship between the difficulty on the network and the average time block set by the network in bitcoin case of around 10 min is set for taking stale blocks into account. This is because of situation like stale blocks could occur more often on the network with more miners, less difficulty and the block time being faster. Transactions in a stale block would then in return become unconfirmed and go back into the mempool. But at one point in time your transaction was confirmed and was truth to the network perimeters. The network is across the whole world and take time for all node or servers to receive the Longest chain as the most honest POW. So a good practise is, if you send a transaction or receive one wait for around 6 blocks confirmation. This is to insure that your UTXOâs are not in a stale block.

- There can only be one truth. So at first both blocks will be added and propagated to their closest nodes for validation. The chain which finds faster the nx block (better 5 blocks) by hashing appends first another block and becomes the longer chain and because of that the validation. The competing chain gets rejected and all the TXs inside the block are going back to mempool
- Stale blocks are blocks that were in the BC at one time but than got dropped
- Stale blocks occur when there is another truth/chain at the same time which gets the improval because of his length
- Because you have to assure that the block with your transaction doesnât get dropped
