The Bitcoin network occasionally experiences temporary forks, resulting in “orphaned” blocks that are not part of the longest chain. During a chain reorganization, transactions can appear confirmed and then suddenly become unconfirmed again as the network converges on the valid chain. A well-designed wallet like Mycelium handles this event gracefully. The mycelium wallet continuously monitors the network’s agreed-upon state. If a reorganization occurs, it will automatically update its transaction history to reflect the new longest chain. A transaction that was once confirmed might temporarily revert to an unconfirmed status until it is included in a new block on the valid chain. This process is automatic and ensures that your wallet’s balance always reflects the true, consensus state of the Bitcoin network, protecting you from accepting invalid payments.
