StarkWare Debuts "SN Stack" Appchains on Starknet

StarkWare has announced the launch of appchains on the Starknet layer 2 network using the new "SN Stack" developer toolkit. It will allow for the creation of validity rollup chains with custom parameters (e.g., block times and sizes), using the Starknet OS, CairoVM, or Blockifier execution engine.

The SN Stack offers multiple tools for developers, including Madara for modular frameworks, Dojo for gaming and on-chain applications, and the StarkWare Sequencer for high-performance public infrastructure, giving ZK-rollups a competitive advantage against optimistic rollups.

StarkWare co-founder Eli Ben-Sasson highlighted the ease and cost efficiency of building appchains with ZK-STARK cryptography, previously limited to optimistic rollups. Additionally, a proof-based interoperability method is in the works that will use Starknet's upcoming prover Stwo (Stark Two).

Bitcoin Investor Ordered to Surrender $124 Million

A Texas court has ordered early Bitcoin investor Richard Ahlgren III to surrender private keys unlocking $124 million in crypto due to tax fraud. Ahlgren must also disclose all storage devices and cease transferring assets without court approval. Convicted in December 2024, Ahlgren’s tax evasion involved obscuring $3.7 million in Bitcoin gains using blockchain obfuscation techniques.

He received a two-year prison sentence for filing false tax returns and illegal cash structuring. The case highlights the U.S. government’s evolving approach to enforcing tax compliance in cryptocurrency. Experts view this precedent as a roadmap for future crypto-related tax enforcement actions.

Coinbase Granted Special Appeal in SEC Case

A U.S. judge approved Coinbase’s request for an interlocutory appeal in its dispute with the SEC over whether certain tokens traded on the platform qualify as securities. The case, centered on the application of the Howey test, will now be considered by the U.S. Court of Appeals for the Second Circuit. Coinbase argues that tokens traded on its secondary market do not meet the criteria for securities.

The judge’s decision paused other proceedings in the case, potentially expediting a resolution. Coinbase’s appeal could influence future crypto regulations, as the SEC leadership shifts under the incoming Trump administration, which is expected to favor a more crypto-friendly approach.
