I've chosen the topic of "Great Wall". There are so many fabulous Dapps developing and growing. Every Dapp is like a brick of the "Great Wall", together making a block chain technology wonder. The "Great Wall of Dapp" continuously undulating along with the terrain, just as the ecology of Dapps follows the prosperity of the block chain market. Different Color of frames flashing in the air are the filming snapshots for different Dapps, indicates the sharp sense of the DappReview. DappReview can help Dapp show itself better and stand out above the surface. From a top view, you can see the Logo of the DappReview.
