RT Jason Hughes (@wk057)That's kind of the point. There's no legit Bitcoin use case for any of this stuff.Anything making legitimate L2 usage of OP_RETURN can easily design around storing hashes only... ideally even just one hash!Anything beyond that can be stored as part of the L2 and doesn't need to be on-chain directly.Any number of anything of any size can be "committed" to the blockchain with a single hash.Have a 5MB ZK proof of XYZ? Hash it.Have a 50MB block from a side chain? Hash it.Have a 50GB 4K m ...

Ethereum Ecosystem Contributions - Polygon hosts Polymarket, a successful "not just boring finance" application, demonstrating valuable use cases beyond traditional finance [1] - Polygon has supported various applications requiring high scalability within the Ethereum ecosystem [1] - Polygon invested significantly in ZK-EVM proving technology early on, contributing to the advancement of the field [2] - Polygon has developed infrastructure for proof aggregation (AggLayer) and other technologies [2] Philanthropic Efforts - Sandeep Nailwal contributed personally to CryptoRelief_, supporting biomedical infrastructure and research in India [2] - Sandeep Nailwal voluntarily returned $190 million from SHIB tokens, enabling the Balvi open-source anti-airborne-disease biotech program [3] - CZ (Binance) donated $10 million in BNB to support the Balvi program, with additional ~$20 million contributed personally [3] ZK Technology and L2 Landscape - The market structure has evolved, with L2 teams and ZK teams becoming separate entities, potentially more efficient than in-house development [5] - The author hopes Polygon can adopt readily available ZK technology for its PoS chain to achieve full security guarantees from the Ethereum L1 [6] - ZK technology has improved significantly, with proving costs around $0.0001 per transaction, challenging the perception of ZK being unviable for hyperscale applications [6]

RT A₿del ∞/21M (@dimahledba)Concrete plan to build a Starknet-based L2 on top of ZCash ?- plumbing of the TZE architecture in Zebra using librustzcash- create the stark verification TZE and integrate stwo Cairo proof verification- update a ZCash SDK to be able to construct transactions using the new TZE- generate a proof of Bitcoin header chain- submit and verify the proof to a ZCash modified node- integrate this TZE pipeline in a modified Starknet sequencerHold my beer for a month and let's see.A real cool ...

and again, this is not necessarily an L2 exclusive problem, L1s without sufficient geo decentralization are also vulnerable to thisthe difference is that the L1 requires more things to go wrong, so it is generally, probabilistically more resilient (but not always) ...
