Of, for love of fleep! Kickstarter doesn't need fleeping blockchain!
For those unware of what it is, to quote IBM:
"Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding). Virtually anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for all involved."

Blockchain is an underlying technology to bitcoin systems - it supports the creation of an immutable ledger of transactions independent of the people who make the transactions. In bitcoin's case, it keeps the people who make the transactions anonymous.
Since bitcoin is (nigh inexplicably) a big thing, "blockchain" has become the new buzzword technology.
