Blockchain's rigidity limits Web3. Web3's scalability and future lie beyond traditional blockchains. Expect a shift toward flexible, verifiable systems prioritizing efficiency over rigid total ordering Opinion by: Grigore Roșu, founder and chief executive officer of Pi Squared For some, the audacity of questioning the primacy of blockchain in Web3 is borderline heretical. The idea that decentralization and progress could exist without blockchains seems absurd to those who built careers around Bitcoin, Ethereum, and their descendants. Given blockchain's well-documented scaling limits, however, there is an argument to be made that Web3 doesn't actually need blockchains to thrive. Instead, it requires payment systems and verifiable settlement systems that are super fast. Blockchains are just one way to achieve that, not the only way. While blockchain solved the double-spending problem, it introduced its own architectural burden: the rigid fixation on total ordering, dictating that every transaction must wait its...

Security should be transparent, auditable, and accessible to everyone building in this space, a Safeheron spokesperson told Cointelegraph. Safeheron, a digital asset infrastructure provider based in Singapore, has introduced an open-source Trusted Execution Environment (TEE) framework. This solution could bolster security and privacy for Web3 in sectors like decentralized finance (DeFi), payment services, and decentralized autonomous organizations. The TEE framework is the first built upon the native Intel SGX SDK and developed using modern C++, a general-purpose object-oriented programming language often used for operating systems, game development, and high-powered computing. Safeheron decided to open-source the framework because the company had seen growing concerns across the industry about closed, opaque systems, especially as security incidents have become more widespread.

Web3 social network Zora’s recent airdrop led to a wave of discontent on social media, but creators and builders are convinced that the future of creativity is still onchain. Onchain social network Zora has built a reputation as a popular tool for artists, musicians and other creatives to monetize their content onchain, but the recent launch of its eponymous ZORA token has left many users confused and dissatisfied. The token’s price tanked shortly after launch, with users and observers complaining about everything from poor communication from the team to the token’s distribution and utility models.  This comes amid an overall decline in interest in the onchain creator economy and a changing perspective on whether blockchain tools like non-fungible tokens (NFTs) are still useful for creatives who want to monetize their work on the blockchain.
