A blockchain is similar to a huge electronic ledger.
It’s a continuous uninterrupted chain of blocks that can store information about financial operations and almost anything that has any value. Blocks in this chain consist of transactions sent from various wallets, including Guarda Wallet, MyEtherWallet, Coinomi, Exodus, Jaxx and others.
Blockchains let us track the addresses of senders and receivers of transactions as well as the balance on a particular address and often the amount of transferred coins. When you check your balance or transaction history in Guarda Wallet, you see data directly from the blockchain.
Guarda itself doesn’t store it.
