Blockchain: Is it a hype or a hoax?  25

5. Metamask internals: By now, you would have already known

about public/private keys. Your wallet shows you a public key

as highlighted in the figure 1.13. My public key looks like:

0x559316c4cB374933eC7aBd9675617AD20295Dc26

You can check all transactions using this public key on

https://etherscan.io as it is one of the Ethereum blockchain explorers.

The private key on the other hand is like a key to your vault which

must be always kept secret from others. You can export the private

keys to secure them safely within the wallet as listed below.

With the Metamask wallet, go to account details as shown in

the figure.
