Brickblock is a blockchain-based project that allows the participants within the ecosystem to sell/invest real-world tokenised assets. Sellers are able to offer real-estate and investment funds to investors. On the other end, Investors purchase asset-backed tokens named Proof-of-Asset token with cryptocurrencies.

Brickblock issued the BBT Ethereum-based ERC20 token, which will be distributed to the contributors of the fundraiser. The BBT tokens are needed to generate new access tokens. The access tokens (ACT) are the fees required to keep the Proof-of-Asset operating and alive.
