The linking of a block of transactions to the rest of the chain is achieved via energy expenditure. The block must have a specific cryptographic fingerprint for this, which will be found in the next block. This is “Proof of Work (#PoW).” 7/10

The system solves the double-spending problem “by using a peer-to-peer distributed timestamp server.” Transactions are assembled within dated blocks, added one after the other, “thus forming a chain”—the blockchain. 6/10

Transfers take place between public keys (or addresses), so “the public can see that someone is sending an amount to someone else.” However, “confidentiality can still be maintained [...] by keeping public keys anonymous.” 5/10
