ACID

ACID stands for:

• A—Atomicity: The chaincode programming model is an all-or-nothing behavior, which allows you to group activities together. Either everything happens, or it doesn't.
• C—Consistency: We believe the new world of NoSQL fudges this one. I believe this means the same as the C in CAP.
• I—Isolation: Isolation indicates that two transactions are serialized, which is exactly what block construction and chaining does.
• D—Durability: The chaining and replication all over the network ensures that if one or more nodes go down, data won't be lost. This is why everyone wants to bring a node and why those nodes should not be not co-located.
