The new idea is based on the gradient element of the previous logo. The four colors of it represented idea, team, product, and community. Each color has a different portion of the gradient surface as a metaphor for moving from a small idea to a larger community.
The new set of colors has been recreated from the gradient. There are 15 blocks used in the logo, the number of blocks was inspired by the Merkle Tree hash structure (1,2,4,8...). The blocks are combined in a chain as a reference to blockchain technology. The logo turned out to be geeky, as an open-source community logo should be.
