A blockchain is best described as a public database that is updated and shared across many computers in a network.
"Block" refers to the fact that data and state are stored in sequential batches or "blocks". If you interact with the blockchain, the transaction data needs to be added to a block for it to be successful.
"Chain" refers to the fact that each block cryptographically references its parent. A block's data cannot be changed without changing all subsequent blocks, which would require the consensus of the entire network.
Each new block and the chain as a whole must be agreed upon by every computer in the network. These computers are known as "nodes". This is so everyone has the same data. To accomplish this distributed agreement, blockchains need a consensus mechanism.
Why does Synergy of Serra use blockchain technology?
The blockchain Synergy of Serra uses allows for the ownership of digital assets through non-fungible tokens (NFTs). It also allows super-secure, transparent transactions to happen.
These factors combined mean that you truly own your digital assets on Synergy of Serra and you will be able to trade them freely, just like physical trading cards, but in a perfect information economy.
Using the blockchain also means Synergy of Serra can deploy smart contracts to develop unique game features such as earning Fame (see The Fame) or winning a Golden Ticket (see here).
