  Blockchain solves the problem of double-spending in digital transactions by using a decentralized network of computers, known as nodes, to validate and record transactions. When a transaction is initiated, it is broadcasted to the network and verified by multiple nodes. Once a consensus is reached among the nodes, the transaction is added to a block and added to the blockchain. This ensures that the transaction is legitimate and prevents the same digital currency from being spent multiple times. The decentralized nature of blockchain makes it extremely difficult for any single entity to manipulate the transaction history and engage in double-spending.

  Double-spending in digital transactions is a major concern, as it would allow someone to spend the same digital currency more than once. Blockchain solves this problem by introducing a consensus mechanism, such as Proof of Work or Proof of Stake, which requires participants in the network to solve complex mathematical problems or stake their own digital currency to validate transactions. This ensures that only valid transactions are added to the blockchain, preventing double-spending. Additionally, the transparent and immutable nature of the blockchain allows anyone to verify the transaction history, further reducing the risk of double-spending.
