SUMMARY

In our previous Arc 101 episode, we covered Arc's three-layer architecture:

  • The Execution Layer
  • The Consensus Layer
  • The Middleware that connects them.

Now let’s see Arc’s architecture in action.

In Arc 101 episode 4, we follow a single USDC transaction from start to finish, tracing every layer it touches, every validation it passes, and how it moves from send to final settlement.

Arc is an open L1 blockchain launched by Arc Network Services LLC ("Arc LLC") and operated by a permissioned validator set. Arc LLC provides software services only and does not offer regulated financial or advisory services. Arc has not been reviewed or approved by the New York State Department of Financial Services or any other regulatory authority.

The Arc network is provided "as is" and "as available." Use of Arc involves inherent risks associated with blockchain technology, including smart contract vulnerabilities, network disruptions, and the absence of recourse for transaction errors or losses. The ability to transact on Arc depends on the ability to obtain and use USDC to pay gas fees. Neither Arc LLC nor any permissioned validator is responsible for the content, accuracy, legality, or functionality of third-party applications, protocols, or services built on or integrated with Arc. You are solely responsible for features or services you provide to users, including obtaining any necessary licenses or approvals and otherwise complying with applicable laws.

All Arc features may be modified, delayed, or cancelled at any time without notice. Nothing herein constitutes a commitment, warranty, guarantee or legal, regulatory, tax, or investment advice.

Coming soon.
