Blast announced on Friday the closure of its Ethereum layer 2 network. Operating costs now exceed the revenue generated by the chain, and the team no longer sees "any credible path" to a sustainable model. Users have until October 26 to withdraw their assets.

On October 1, 2026, the SEC proposed conditional self-custody and the use of state trust companies for the crypto custody of advisers and funds. Cointribune compares this to the 2025 SEC services letter, which already provided a path, without legal force.

Families tied up, repeat attacks within months, armed robbers: in France, criminals no longer hack your passwords, they break into your home. Why does the security of your crypto no longer depend on your private keys, but on your discretion? Dive into the human side of the digital hack.

Bitget has revised its estimate of the crypto assets affected by the September 24 security incident to approximately $387.5 million, up from its initial estimate of $351.6 million.

This Tuesday, Aave posts the best DeFi rise! Its founder, Stani Kulechov, envisions a crypto token burn in Aavenomics 3.0, and buyers have seized on it. Meanwhile, the US 10-year yield remains very high and DeFi still progresses. Here are the key figures.

Ethereum has set the date: Glamsterdam, its next major update, will activate on the Sepolia testnet on October 6 at 13:53 UTC. Operators have one week to update their clients or face exclusion from the network. This is the final rehearsal before the mainnet, targeted for the fourth quarter of 2026.

Faced with the programmed scarcity of Bitcoin, Strategy reaches a historic milestone by locking in over 4% of all bitcoins in circulation. But Michael Saylor's firm is no longer alone, and other giants like Strive are accelerating the pace. An analysis of an unprecedented treasury race.

Vitalik Buterin believes that Hegota, the Ethereum fork planned for 2027, could be the last update based on technologies familiar to developers from 2015. The network will continue to evolve afterward. Its future transformations will rely more on cryptographic proofs, parallel execution, and formal verification.

Bitcoin records its second-best Q3 performance in history with +43.5%, while Ethereum explodes its record with +71%. A quarter driven by strong ETF demand and controlled profit-taking. At the same time, the gold-bitcoin rotation theory reemerges… coincidence?

What if Bitcoin could whisper your transactions instead of shouting them in public? Three researchers have just put a plan on the table that would allow Zcash-style privacy on Bitcoin without touching the protocol.

The Bitget hack ultimately affected about 387.5 million dollars in assets, compared to an initial on-chain estimate of 228 million dollars. The platform claims to have contained the attack but keeps withdrawals suspended during its security checks.

Privacy coins are experiencing a spectacular comeback in the crypto market. In five months, Zcash and Monero have added 24.54 billion dollars in valuation amidst institutional interest and regulatory debates.

In 2026, Kaspa stopped being "just" a fast payments network. After the Crescendo hard fork took the network to 10 blocks per second in 2025, the Toccata upgrade added native smart contracts, KRC-20 tokens and zero-knowledge (ZK) verification in late June 2026. That leaves the question anyone following the project actually cares about: what comes next? The answer is three build-outs, DAGKnight, the climb to 100 blocks per second, and VProgs, plus a Layer 2 ecosystem taking shape, not without friction. Here is what the next upgrades are preparing, and what they do not yet prove.

Solana is generating more fees than Ethereum, but ETH still leads on burn. The gap reveals two very different crypto economic models.

On Monday, US Bitcoin ETFs experienced their best day of 2026 with nearly 1 billion dollars collected in one session, a record not seen since October 2025. IBIT, ARKB, and FBTC led the charge while bitcoin flirted with 87,200 dollars. But one figure spoils the mood.

Ethereum staking regains real momentum, with thirteen times more ETH awaiting entry than exit. This imbalance potentially reduces the available supply, without by itself guaranteeing a price increase.

Solana has tightened its clock a third time since August with 250 milliseconds per block, compared to 300 before. A speed gain, not capacity. Coincidence or not, the announcement comes on the same day the network shows a record of more than 5 billion monthly crypto transactions.

Zcash is not only making headlines on the stock market with the split of its ETF. Behind the scenes, developers are finalizing NU7, the update planned for November 5 to triple the block time and set up a new mechanism for redistributing fees to crypto miners.

Tron, Aptos, BNB Chain, Bitcoin: Chainalysis has just demonstrated that public blockchains also serve as dead mailboxes for state hackers. A North Korean group links three crypto networks to hide its servers, with Iran occupying an address related to Satoshi. Meanwhile, Wall Street predicts $500,000 for BTC.

Bitcoin Core 32.0 nears release with performance upgrades, security fixes and a server vulnerability uncovered with help from an AI model.

Canopy has announced it completed its first named protocol upgrade, Banyan (v2.0), live and with no downtime. The company, which builds a framework for launching onchain apps and sovereign blockchains, ran a network-wide consensus change through its Canopy Auto Update feature. The headline is not only the technical feat: according to Canopy, the same in-place upgrade ability now belongs to every application built on its infrastructure.

While Washington is bogged down in its crypto regulatory framework and American bitcoin ETFs lose hundreds of millions, Deutsche Bank is moving forward. The German bank announces a crypto custody service for its institutional clients, planned by the end of 2026. Bitcoin, ether, stablecoins, Europe is banking cryptocurrency.

OpenAI will not go public in 2026. Sam Altman confirms it, security reasons oblige. But behind this virtuous discourse, Trump's ex-IA and crypto Czar, David Sacks, smells a cartel disguised as virtue. Meanwhile, the AI crypto market does not pause.

BNB Chain proclaims its top global position in RWA growth with +3.6 billion dollars in 2026. Impressive figure on paper. But on the same day, DeFiLlama shows Solana regaining the lead in crypto application revenues and DEX volume, far ahead. Two rankings, one real question: who generates the activity?

A whale opened a long position of 911.55 BTC (70 million dollars) with a 40x leverage on Hyperliquid, less than 1% from its liquidation price. Meanwhile, Michael Saylor posts a minimalist tweet: "Just buy Bitcoin." Between extreme speculation and long-term strategy, here are the two faces of the crypto market.

On September 9, 2026, Solana issued 263,000 tokens in 24 hours, an absolute record. Yet, it is not this figure that impresses the most. With 5.09 million dollars in daily revenues, Solana outpaces all competing blockchains. Between memecoins and regulated markets, discover how the crypto network combines volume and economic solidity.

The 12th edition of the European Blockchain Convention brings together the biggest names in finance moving on-chain in Barcelona on September 16 and 17, 2026. Over two days, the conference aims to bring together in one place an ecosystem usually scattered across European financial centres: banks, asset managers, custodians and crypto-native players. A special rate reserved for the Cointribune community accompanies the event.

Strategy has just bought back 176 million dollars of STRC and doubled its buyback program to 2 billion to reassure the market about its bitcoin-backed securities. Meanwhile, Peter Schiff questions the real demand, and the company's online shop sells a "BTC-themed" sneaker without a bitcoin payment option. Irony or admission?
