@iotex_io v2.4.0 is shipping — our biggest mainnet upgrade of 2026.

It's a mandatory hardfork activating at block 48,985,561 (≈ June 7, 2026 · 23:52 UTC).

Two things we've been working toward all year:
⚡ Pectra EVM — IoTeX is now aligned with Ethereum's latest execution layer:
· EIP-7702 — EOAs can act as smart accounts
· EIP-2537 — native BLS12-381 (bridges, light clients, ZK)
· EIP-2935 — historical block hashes from state
· EIP-7623 — recalibrated calldata pricing

🛡️ Candidate Exit Queue — delegates can no longer unwind their self-stake instantly. Exits now go through a request → schedule → confirm flow, with admission rate-limited at the protocol level. A cleaner, more predictable lifecycle for our delegate set.

What you need to do 👇
▸ Delegates / Full Nodes / API Nodes — upgrade to v2.4.0 before block 48,985,561. Miss it = fork off mainnet.
▸ Wallets & dApps — check your gas estimator against the new EIP-7623 calldata floor, and add support for TxType 0x04 (SetCode) if you serialize raw transactions.
▸ Indexers / Explorers — new on-chain events from the exit queue and 7702 authorization tuples are ready to be indexed.

[IoTeX Developers @iotex_dev]

2026: The year AI gets "eyes and ears." 👁️👂

We're transitioning from simple motion alerts to Edge AI models that actually understand their environment. @iotex_io is providing the infrastructure to decentralize and secure this new nervous system of the physical world.

[IoTeX @iotex_io]

The physical world is "awakening" in 2026! 🌍✨

We’re moving beyond the cloud to a new era of Edge AI. From Small Language Models (SLMs) to embodied intelligence, the future of AI is local, verifiable, and decentralized.

IIP-56 is live on IoTeX Hub and open for vote. 🗳️

Following the @iotube_org exploit on February 20th, we're moving decisively: full deprecation of CIOTX across Ethereum, Base, Solana, BSC, Polygon, and IoTeX with a clean, differentiated wind-down for each network.

✅Affected chains (ETH, Base, Solana): bridge permanently shut down, attacker-minted tokens disregarded, and a dedicated claims portal already live for legitimate holders to reclaim equivalent IOTX → https://t.co/cFOGKggNur

✅Unaffected chains (BSC, Polygon, IoTeX): bridges reopen after a full security review for self-serve migration back to IOTX.

This is step one. IIP-57: Trustless Bridge: Replacing Keys with Proofs is already in the pipeline. We're not patching, we're rebuilding.
Voting closes March 11th. Read the full proposal and cast your vote 👇

🚨IoTeX Mainnet v2.3.4 Upgrade Notice

The @iotex_io mainnet will undergo an upgrade to version v2.3.4. All nodes are strongly recommended to upgrade to this release, to improve network security.

Note: You only need to restart your node with the new v2.3.4 image.

✅Key Features and Enhancements: v2.3.4 introduces a default blacklist configuration to improve network security. This blacklist contains a list of malicious or problematic EOA (Externally Owned Account) addresses that will be filtered by the node.

🚨 IoTeX Core v2.3.0 Mainnet Release
This release introduces a hardfork at block height 41,648,761 (ETA Nov 4, 2025 – 03:45 UTC) and includes two key protocol upgrades that strengthen reliability and prepare the network for future scalability.

✅ IIP-50 — Slashing for Underperforming Delegates: Establishes economic incentives to maintain high-performance infrastructure and ensures reliable consensus participation across all validators.

✅ BLS PublicKey Registration: Enables BLS key registration and updates in candidate transactions, paving the way for upcoming signature aggregation — a major step toward scalable finality.

🔐 This upgrade is mandatory for all delegates to remain in sync with the @iotex_io L1 blockchain.

👉 No changes required to config.yaml or genesis.yaml; simply restart your node with the new image. Full bootstrapping instructions can be found on the IoTeX Github at https://t.co/RKs5rqXi0i

💥 This update marks a significant milestone for the IoTeX L1 — reinforcing performance, accountability, and readiness for large-scale DePIN and RWAI workloads.

[IoTeX Developers @iotex_dev]

🚨 Update on @iotex_io Core v2.3
A minor bug was identified during the Testnet rollout and has now been fixed in v2.3.0-rc13.

🔧 Testnet hardfork details:
Block height: 36,826,561
ETA: Oct 20, 2025 – 11:35 UTC
✅ All Testnet nodes should upgrade to v2.3.0-rc13 and update their genesis.yaml (linked in the release notes below 👇).

With this patch in place, the Mainnet release schedule will be announced shortly, following the successful Testnet validation.

📘 Release notes: https://t.co/OLPMJFsifZ

[IoTeX Developers @iotex_dev]

IoTeX Core v2.3 is live on Testnet ⚙️
@iotex_io continues evolving its L1 toward stronger decentralization, scalability and reliability!

✅IIP-50: This hardfork activates IIP-50 — a major step toward improving network reliability and delegate accountability by rewarding consistency and enforcing fairness. Delegates who fall below the 85% productivity threshold will see deductions from their self-stake.

The goal: ensure every consensus participant operates high-performance infrastructure that supports the network’s growth, while protecting voters and maintaining stable rewards.

✅Also in this release
BLS key registration for delegates — setting the foundation for upcoming IIP-52 signature aggregation.

🚨Mainnet activation expected in the next 1–2 weeks — delegates will receive ample notice ahead of the upgrade. Please note that this is a mandatory upgrade for all nodes to stay in sync.

🚨 IIP-52: BLS Signature Aggregation — Voting is Live

ℹ️ Right now, every @iotex_io L1 block finalized by consensus carries a signature from each delegate: that’s ~2.3KB of extra data in every block.
It's been working faultlessly until now, but it slows propagation and limits scalability.

💊 IIP-52 proposes a fix: aggregate all validator signatures into a single 96-byte BLS signature with a lightweight bitmap showing who signed.

The result?
✅ Blocks shrink dramatically → faster propagation across the network
✅More room for transactions → better throughput
✅ Technical foundation to safely scale validators

This change is already common in networks like @ethereum 2.0, and now it’s on the table for @iotex_io.

[IoTeX Developers @iotex_dev]

At @iotex_io, protocol upgrades follow a clear, transparent path:

Every change — from consensus rules to scalability features — goes through the IoTeX Improvement Proposal (IIP) process:

✅Drafted openly by devs & community
✅Reviewed in the Forum
✅Voted on-chain via the Governance Hub
✅Implemented into IoTeX L1

Recent IIPs covered slashing, stake-weighted consensus, BLS signature aggregation, and dynamic delegate scaling — upgrades that make the network more decentralized, reliable, and capable of supporting RWAI.

🚨 IIP-52: BLS Signature Aggregation is open for discussion in the @iotex_io community forum 🗳️

ℹ️ This proposal introduces BLS signature aggregation, compressing all delegate signatures for block finality into one single proof instead of storing them individually.

Today, every delegate signs a block separately. With 24 delegates, that means 24 different signatures — adding ~2KB to each block and slowing down propagation.

Why this matters:

✅Shrinks block footers from ~2KB → 96 bytes
✅Faster block propagation → quicker confirmations
✅More room for transactions → higher throughput
✅Scales smoothly as the number of delegates grows

This is the same cryptographic upgrade used by Ethereum 2.0 and other top chains to improve efficiency and scalability.

🚨 IIP-50 is now open for voting on the @iotex_io Hub!

🔹 This proposal introduces slashing for underperforming delegates, adding a real economic cost to missed blocks.

👉 It’s a big step toward fairness and stronger network reliability.

Why it matters:

✅ Delegates under 85% productivity are penalized—losing self-stake, not just rewards.
✅ Penalties go back to the reward pool, not lost.
✅ Delegate replacement thresholds prevent unreliable nodes without being overly harsh.
✅Stronger incentives for top-performing nodes, and clear disincentives for poor reliability.

🚨 IIP-50 is open for discussion!

The goal of this proposal is to strengthen @iotex_io consensus by holding validators accountable.
The proposal introduces slashing for chronically underperforming delegates, protecting network reliability and rewarding those who keep IoTeX running at full speed.

A stronger network means:
✅ Better uptime for dApps & users
✅ More fairness for stakers
✅ A healthier reward pool
