Layer-2 rollups, data-availability layers, sidechains, and throughput milestones.
The DEX wind-down closes a six-year run for one of Ethereum's earliest zkRollup experiments, with the team returning remaining user funds via a contract upgrade.
The protocol still runs, but the relayer powering its DEX goes dark, and LRC delistings earlier this year stripped it of the trading flow a non-EVM rollup needed to keep the lights on.
John Egan frames throughput and finality, not fees, as the metric that decides whether AI-to-AI commerce runs on-chain at all.
Two block-production halts inside 48 hours, traced to one shared bug, but the chain's integrity held and no funds were lost. The remediation list is the part builders will read.
Two block-production halts in 36 hours land just ahead of Coinbase's L2's planned Beryl upgrade, putting the network's reliability narrative under fresh scrutiny.
A week of project-level pivots across L2s, perps, and prediction markets, headlined by Sophon's Base migration and Berachain's BGT fork.
A one-hour Activation Registry warm-up window is the reason the date slipped, and it determines when the first B20 tokens can actually go live on the L2.
A $60M-raised ZK L2 folding its native chain to live as a product studio on Base signals the infrastructure layer is consolidating and the application layer is where new teams are now spending.
It's the second major outage for the Coinbase-backed Ethereum layer-2 in under a year, and the root cause still hasn't been named, putting the network's reliability thesis back under the microscope.
The invalid block stopped production at height 47806542, taking deposits, withdrawals, and client software offline before partial sequencer recovery.
Base is a Coinbase-incubated layer-2 with billions in TVL; sustained downtime on a venue that size tests the assumption that rollups inherit Ethereum's uptime guarantees.
The Coinbase-incubated layer-2 hit its second notable outage this year, freezing deposits and withdrawals and exposing the operational risk of a low-redundancy sequencer setup.
Another appchain calls it: maintaining a rollup costs millions a year, and Sophon's team decided building the app is the better bet than running the chain underneath it.
The milestone matters less for the number than for what it signals: $4.1B in circulation is now moving natively across two dozen chains, not bridged.
The Leios Musashi Dojo rollout on June 23 is a real engineering milestone, but with ADA down 1% to $0.148 and active staking addresses near a 120-day low, the network shows no signs of life around…
The arrangement lets Optimism run Ink's production stack while the Ink Foundation redirects engineering capacity to ecosystem growth and new financial products.
When Layer 2 fees fall below the cost of executing on the L1 itself, the original scaling thesis stops paying out, and dozens of rollups are left searching for a reason to exist.
The exploit is a KelpDAO incident, but the structural story is the $3B rotating to Chainlink's CCIP as DeFi projects dump LayerZero for cross-chain messaging.
Tron's daily active count now sits 40-60% above its major L1 peers, a usage gap that has held for months as USDT settlement and DeFi flows concentrate on the network.
The dollar loss was small, but the flaw class is the same one behind $340M in cross-chain bridge hacks already this year, and the root cause was a prover signing key left exposed on GitHub.
