Solana developers are considering a major change to prevent disagreements between the software programs securing its crypto network. On October 30, 2026, Anza CEO Brennan Watt proposed creating a single official specification covering the blockchain's operating rules. The draft already contains 18 technical sections, including transactions, consensus and validator rewards. The proposal aims to reduce the risk of conflicting interpretations that could disrupt the network.

Ethereum blobs are only guaranteed for about 18 days, but archives preserve them. The first blob from March 2024 was still present in October 2026.

Chainalysis, one of the leading blockchain analysis companies, was the victim of a cyberattack using techniques associated with artificial intelligence. The company confirmed on October 30, 2026, that a hacker had accessed its internal systems and certain client data. Names, email addresses, and identifiers are among the compromised information. Crypto investigation records and passwords do not appear to have been affected, according to initial investigations.

Every crypto product sits on a blockchain API. A wallet that shows a balance calls one. A trading bot calls two or three. An AI agent that answers "what is in this wallet" calls one through MCP. Four layers do that work. Node providers expose raw chain state over RPC. Indexers turn raw logs into queryable tables. Data APIs return priced, decoded, ready-to-render values. Swap rails move assets between chains and venues. Most production stacks combine at least two of the four.

With $50 million, Justin Sun grabs nearly 3% of the total $PEPE supply and triggers a shockwave in the crypto market that immediately propels the memecoin.

BNB Chain prepares a new Layer 1 blockchain for early 2027, with an ambition: to exceed 100,000 transactions per second and reduce block production to 200 milliseconds. The project, provisionally called New L1, will operate alongside BNB Smart Chain without creating a new crypto. Changpeng Zhao (CZ), founder of Binance, supports this approach. The first experiments are already underway, but the public network is not yet available.

The Common Sense Leadership Fund, an American conservative group, urges S&P 500 CEOs to block the tokenization of RWAs of their shares on decentralized networks. Between regulatory panic, hardware flaws, and admission of adoption, the crypto RWA sector reaches a new level of intensity.

Blockchain Life 2026 takes place on December 1st and 2nd in Dubai. Tickets are at the early bird rate, more than -50% off the last chance price.

Ethereum researchers are now using artificial intelligence agents to analyze the unexpected effects of Glamsterdam on existing contracts. This initiative comes after the postponement of the planned test on Hoodi, but it does not mean that the issue is already resolved.

A Bitquery study reveals a significant gap between the gains displayed on Pump.fun and the profits actually derived from trading. Out of 752.5 million dollars analyzed, only 193.9 million come from purchases followed by sales. The rest is mainly explained by token transfers and suspicious operations.

After the alert on the Keystone site leak on October 24, six major cold wallet brands have now been hit by hardware flaws or data breaches in 2026. An unprecedented crisis of confidence is shaking the crypto ecosystem.

Benyamin Netanyahu asked his advisors to prepare a blockchain-based plan to reduce Israel's vulnerability to potential banking sanctions. However, the Prime Minister did not specify the cryptos considered, the project leaders, or the timeline.

China sets 2030 as the deadline for its national blockchain network. Its 15th informatization plan specifies priority regions and targeted uses, from finance to logistics. However, Beijing does not question its ban on crypto-related activities.

Ethereum researchers want to reduce the finality time of transactions from 16 to 4 minutes. Behind this technical improvement is a concrete economic issue: to allow transfer services to mobilize less capital while waiting for the final confirmation of operations. For now, the project is still under study and does not plan any deployment date.

The PHP project asks administrators to update their servers after the discovery of two vulnerabilities that can lead to remote code execution. The alert concerns a language very present on the Web, but the 70% figure mentioned in the press does not correspond to the number of sites actually vulnerable.

Solana replaced TowerBFT with Alpenglow on its mainnet on October 21, in its most significant consensus change since launch. The new protocol targets a finality close to 150 milliseconds, compared to about 12.8 seconds previously, but part of the planned architecture is still to be deployed.

Since this morning, a major network outage has affected Google Cloud servers in London and paralyzed Revolut. Blocked bank cards, impossible withdrawals, and crypto wallets displaying zero… are your funds safe?

Ethereum is preparing a new important test for Glamsterdam. On October 26 at 17:42 UTC, the upgrade will be activated on Hoodi with a limit of 200 million gas per block. The testnet will thus go well above the approximately 60 million used as a reference before. After Sepolia in early October, Ethereum wants to verify that such capacity can operate without making blocks too heavy to process.

After 12 years of total inactivity, two Bitcoin wallets dating back to 2013 have just reactivated 417 BTC, turning a tiny initial investment into a fortune of 33 million dollars.

Ethereum prepares to increase its gas limit from 60 to 200 million per block as part of the Glamsterdam upgrade. This increase represents a factor of 3.3, not 33, but it currently only applies to test networks, with no date set yet for the mainnet.

While Bitcoin ETFs record over $82 million in outflows in 24 hours, the chart pattern signals a bullish accumulation triangle that could soon push BTC towards $90,000.

Vitalik Buterin pushes the privacy of his AI agents very far. The co-founder of Ethereum has just unveiled a "paranoiac mode" combining Tor, private payments via zkAPI, dummy network traffic, and local rewriting of prompts. Each conversation goes through a different Tor circuit. Even the payment to the AI provider is designed to no longer directly reveal the user’s identity.

Twist on the Fed! The probability of a rate hike in October collapses from 48% to 13% on Polymarket. Between purged panic and massive accumulation, is Bitcoin preparing for the big shock of the fourth quarter?

The crypto network Solana plans to activate Alpenglow on October 21, 2026. The update targets transaction finality of about 150 milliseconds, compared to 12.8 seconds with TowerBFT.

A whale sold 1,074.36 bitcoins for $89.5 million and bought 36,159 ethereum for $90.6 million in three days, according to Lookonchain. Here is what is known, and what this operation hides.

The Japanese company Metaplanet takes a new step in its financial strategy. By issuing 52 billion yen (~$328 million) of zero-coupon convertible bonds, the company aims to restructure its debt and buy back its own shares without selling its Bitcoins.

China wants to build a national blockchain network. In a strategic document published on October 9, 2026, the Central Committee of the Chinese Communist Party and the State Council list this infrastructure among the priorities of economic modernization. The goal is to better connect businesses, IT systems, and data nationwide.
