Arc’s Stablecoin Settlement Design, Privacy, and MEV Plans

Summary

The document describes Arc as a Layer 1 blockchain developed for stablecoin finance and asset tokenization, with enterprise and institutional users in mind. It says USDC would serve as the native gas asset, using a fee mechanism inspired by Ethereum, while a Tendermint-based consensus engine is intended to provide fast deterministic settlement. The validator network is described as permissioned and institutionally oriented.

For privacy, the article outlines confidential transfers that encrypt amounts while leaving addresses visible, initially using trusted execution environments and naming MPC, homomorphic encryption, and zero-knowledge proofs as possible later additions. It also lists planned MEV controls such as cryptographic mempools and batch processing. These are architectural descriptions and roadmap items, not evidence of deployed performance: several technical sections lack supporting detail or metrics, and the comparison with Libra and Monero is not developed. The article offers no independent security or throughput evaluation.

Key ideas

• Arc is presented as a settlement chain focused on stablecoins and tokenized assets.
• The design uses USDC for transaction fees and a permissioned validator network.
• Confidential transfers are described as concealing amounts while leaving participant addresses visible.
• Several cryptographic privacy tools and MEV controls are framed as planned development.
• The document does not provide independent security, throughput, or deployment evidence.
