Coinbase founder Brian Armstrong has received over 150 project applications and announced an 11th startup idea, a Web3 version of LinkedIn, which aims to revolutionize employment and credential verification in the emerging Web3 era. This new concept would allow corporations to issue soul-bound NFTs to validate employment and qualifications, providing a secure and transparent method of certifying professional qualifications.

Armstrong also proposed other ideas, including a decentralized currency that tracks consumer prices, an on-chain reputation protocol, and a new era of advertising with on-chain ads. However, some experts believe that some of these ideas may face challenges and take time to gain traction.
