The article presents Optimism's OP Enterprise as the tool for this, saying it offers modular options such as block builder policies, pluggable ZK and fault proofs, and flexible data availability. It names Kraken (Ink), OKX (X Layer) and Sony (Soneium) as examples of companies that have built on the Optimism stack, which it says has more than 50 chains in production securing over $16B in value. ## 11. @Optimism: 120 builders rewarded with 1.3M OP in Retro Funding - Kiwi News: https://news.kiwistand.com/stories/Optimism-120-builders-rewarded-with-13M-OP-in-Retro-Funding?index=0x6829119a299a3e688c6077b05b908414a6e0fb61332a5b47e4b4aeda4831cf4da35ea111 - Source: https://xcancel.com/Optimism/status/1923081349566693797 - Shared 17 May 2025, 1 upvote, 0 comments ## 12.
