What to know:
- Aztec Network launched its Ignition Chain, becoming the first fully decentralized Layer 2 protocol on Ethereum's mainnet.
- The Ignition Chain uses zero-knowledge proofs to provide private and scalable blockchain transactions, enhancing DeFi applications.
Privacy-focused Ethereum Layer 2 Aztec Network's Ignition Chain flipped the switch on Wednesday, becoming the first fully decentralized Layer 2 protocol on the mainnet.
"Aztec just shipped the Ignition Chain, the first fully decentralized L2 on Ethereum. This launches the decentralized consensus layer that powers the Aztec Network," Aztec announced on X.

The event happened when the validator queue hit 500, a key checkpoint that signals readiness to secure the network and initiate block production
The Ignition Chain is the engine powering Aztec's goal of being a fully decentralized "private world computer," enabling developers to create DeFi applications while maintaining total secrecy.
It combines zero-knowledge proofs with Ethereum’s robust security, enabling truly private, scalable blockchain transactions. So, users get the speed and cost savings of L2, plus privacy that’s been missing in many decentralized finance (DeFi) applications.
Anyone can become a validator or sequencer by staking AZTEC tokens to earn rewards and early birds get a bonus to jumpstart decentralization. The AZTEC token auction is scheduled for Dec. 2, opening the doors for more community involvement.
The debut means privacy-focused, decentralized L2 networks are not just experimental projects, they’re about to become vital infrastructure shaping the future of blockchain.
Why 500 validators?
Ethereum’s consensus depends on distributed trust—meaning lots of independent validators confirm transactions. But if too many validators try to join all at once, network stability risks taking a hit. So new validators queue up, entering in stages.
Reaching 500 validators means Aztec Ignition Chain has hit a critical mass: a strong, resilient base of participants ready to defend the network. More validators mean better decentralization, a lower risk of a bad actor taking control, and a network secure enough to launch fully on Ethereum.

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Crypto ETFs with staking can supercharge returns but they may not be for everyone
From yield potential to custody risks, here’s how direct ETH and staking funds compare for different investor goals.
What to know:
- Investors can now choose between owning ether directly or buying shares in a staking ETF that earns rewards on their behalf.
- While staking ETFs offers yield, they come with risks and less control than holding ETH in an exchange or wallet.
- Grayscale’s Ethereum staking ETF recently paid $0.083178 per share, yielding $3.16 in rewards on a $1,000 investment.
