What is ArcBlock
ArcBlock is a blockchain and application platform; its ArcBlock Chain is a Layer 1 network for identity, assets and agreements. ABT is the native token of the public ArcBlock network and also exists as an ERC-20 token on Ethereum and on Base. In 2026 ArcBlock focuses its product work on ARC (Agentic Realm Computer).
Network and consensus
| Parameter | Details |
|---|---|
| Type | Application-focused Layer 1 blockchain (ArcBlock Chain) |
| Smart contracts | Native transaction types for transfers, token issuance, asset operations and staking instead of a separate smart contract per basic operation |
| Runs on | Native ABT on ArcBlock Chain; ERC-20 ABT on Ethereum and ABT on Base, bridged 1:1 in token units |
What ABT is used for
- Paying network fees and paying in applications that accept ABT.
- Stake for Gas: staking 1 ABT on the public network gives a transaction-fee exemption while eligible.
- Stake for X: locking ABT as a bond behind an agreement with a service, which an authorised party can slash if the agreement is broken.
Who develops and governs ArcBlock
- Founders
- Robert Mao, founder of ArcBlock
- Open source
- Blocklet Server security fixes are published as separate commits in the public repository

Security and audits
- In October 2026 a security review of Blocklet Server found authorization-scope, logging and input-validation issues; fixes ship in 1.17.13-beta-20261019-082907-fe71de61 and later, and hosted apps were already patched.
- Abuse of Stake for Gas can lead to the whole stake being slashed to the community pool.
Security incidents
No security incident is recorded in the sources checked on 31 October 2026 (the company’s own channels and incident databases): defillama.com/hacks, hacked.slowmist.io/search, rekt.news/leaderboard, arcblock.io/en/articles
Risks and caveats
- Moving ABT between ArcBlock Chain, Ethereum and Base relies on a bridge, which adds its own security assumptions.
- Staked ABT is locked and can be slashed by the party the stake authorises, under the declared rules.
- Blocklet Server 1.x hosted services end on 31 December 2026; Launcher-hosted applications stop and legacy hosted runtime data is deleted.

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
