The research seeks to enhance the covertness and efficiency of communications in Web3.0 environments, where transparency and decentralized architectures dominate.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Design\/methodology\/approach<\/jats:title>\n                  <jats:p>Two blockchain-based lightweight covert data transmission schemes are proposed. The first scheme involves sharing private keys, while the second scheme avoids sharing private keys to prevent the potential loss of digital currency. Both schemes are designed to be implemented on lightweight devices. The solutions were tested on Raspberry Pi and the Ethereum Testnet to assess their feasibility.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Findings<\/jats:title>\n                  <jats:p>The results demonstrate that both schemes improve covertness and efficiency for Web3.0-compatible devices. The second scheme, which avoids sharing private keys, effectively addresses the risk of blockchain private key leakage while maintaining low resource consumption. These findings provide evidence that the proposed solutions are suitable for lightweight devices and offer enhanced security without compromising performance.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Originality\/value<\/jats:title>\n                  <jats:p>This research offers a novel approach to covert data transmission in Web3.0 environments by leveraging blockchain technology.
