HugeCoin or BigCoin has a block time of 30 seconds and is proof of work based.

Although 'HUGE' was the ticker assigned at the deployment of the BigCoin Token's smart contract, it is already in use by another asset that has a larger market presence and higher trading volume on major exchanges. Due to this pre-existing association and to avoid confusion in the marketplace, the alternative ticker 'BIGCOIN' has been adopted for this token. This designation is specifically used to ensure that assets are distinctly identified.
