# Introduction
Introducing [Gravity](https://gravity.xyz/?utm_source=medium\&utm_medium=blog\&utm_campaign=gravitylaunch) — among the fastest EVM Layer 1 blockchains, with a native, protocol-level oracle. Gravity combines a parallel EVM execution layer with fast-finality BFT consensus and verified on-chain access to real-world data, giving developers a chain fast enough and connected enough to run the next generation of applications, like AI agents acting on behalf of users. Gravity is built to be a **world computer**: a single, credibly neutral execution environment where applications run transparently, settle instantly, and read trustworthy external data without depending on off-chain middleware. As autonomous AI agents become first-class economic actors, Gravity serves as the **foundational harness that connects agents with one another and with the world** — a shared substrate where agents can transact, coordinate, and act on verified information with code-is-law guarantees. ## Gravity At its core, Gravity pairs the fastest EVM execution available — [Gravity Reth](/research-and-development/greth.md) running the [Grevm](/research-and-development/grevm2.md) parallel execution engine — with a state-of-the-art, AptosBFT-derived consensus protocol that delivers high throughput and near-instant finality. This is the same foundation you can run yourself with the [Gravity SDK](/research-and-development/gravity-sdk-tutorial.md). This work doesn't stay in our own fork. We are one of the most active external contributors to [Reth](https://github.com/paradigmxyz/reth), the upstream execution client maintained by Paradigm, and a number of our mempool and execution optimizations have already been merged back into the main repository — benefiting the entire Reth ecosystem, not just Gravity. See the [full list of upstreamed pull requests](/research-and-development/greth.md#high-throughput-mempool) for details. What sets Gravity apart is its **native oracle**, built into the protocol rather than bolted on as a set of smart contracts. The chain itself can fetch and verify external data — state from other blockchains, JWK providers for keyless authentication, DNS, and on-demand requests — and make it available on-chain with the same security guarantees as the rest of consensus. For AI agents and high-stakes applications, this turns the chain into a trustworthy bridge between on-chain logic and real-world inputs. Gravity is fully EVM-compatible, so existing Ethereum tooling, contracts, and wallets work without modification. ## Key Features of Gravity * **High-Performance Execution:** Gravity integrates the fastest EVM execution layer, Gravity Reth, with the Grevm parallel execution engine and an AptosBFT-derived consensus protocol — together delivering high throughput and near-instant finality. On a live 3-validator cluster (8 vCPU / 16 GB nodes), Gravity sustains **\~9.5k–11k TPS** of ERC20 transfers with **\~200 ms** block times. See the [3-validator cluster benchmark results](/research-and-development/benchmark-results.md) for the full setup and methodology. * **Native Oracle:** A protocol-level oracle brings verified external data on-chain — other blockchains, JWK providers, DNS, and on-demand requests — without relying on off-chain middleware. * **A Harness for AI Agents:** Fast finality, low fees, and trustworthy data access make Gravity a natural execution and coordination layer for autonomous agents acting on behalf of users. * **EVM Compatibility:** Gravity is fully EVM-compatible, allowing developers to deploy and interact with smart contracts seamlessly. ## Use Cases * **Autonomous AI Agents:** Agents need a place to hold assets, transact, and coordinate with other agents while reading verified real-world data. Gravity's fast finality and native oracle make it a credible execution and settlement layer for agent-to-agent and agent-to-world interactions. * **On-Chain Applications with Real-World Data:** Because the oracle is part of consensus, applications can depend on external data — prices, cross-chain state, identity attestations — without trusting a separate middleware operator. This unlocks fully on-chain markets such as perpetual DEXs and prediction markets, where fast, verifiable price and outcome data is the core of the product rather than an afterthought. * **High-Throughput dApps:** Parallel execution and near-instant finality support consumer-scale applications that would be infeasible on slower chains, shifting mission-critical logic from private, unauditable backends onto an open, code-is-law database. * **Keyless & Passkey Accounts:** Native JWK verification and secp256r1 precompiles let developers build wallets and account-abstraction flows that authenticate with passkeys and familiar identity providers. ## Network Gravity Mainnet (L1) is live as the production chain (chain ID `127001`) — see [Gravity Mainnet (L1)](/gravity-networks/l1-mainnet.md) to connect. A public [Gravity Longevity Testnet (L1)](/gravity-networks/l1-longevity-testnet.md) is available for development. Gravity originally launched in 2024 as the Gravity Alpha Mainnet, an Ethereum rollup on the Arbitrum Nitro stack (chain ID `1625`). That network is still operational and its documentation is preserved under [Legacy: Alpha Mainnet (L2)](/legacy-alpha-mainnet-l2/legacy-l2.md), but new development should target L1. The Alpha Mainnet (L2) is set to be deprecated in favor of L1, and will be unsettled in December 2026. ## Join Us The universe cannot exist without gravity; it's the cosmic glue that holds everything together. Similarly, Gravity is the foundational layer that will empower the next era of the Internet — and the agents that increasingly run on it — to grow and thrive. Join us as we venture into this exciting new phase to transform the future of the Internet.
