node

Libbitcoin developer @evoskuil stated that the latest version of Libbitcoin Server can complete the initial block download of a Bitcoin full node in 55 minutes and perform full verification. This speed improvement comes from a new GPU-based signature verification system that runs in parallel with conventional script verification, rather than as a separate step.The software does not pause execution to verify each ECDSA and Schnorr signature; instead, it captures signature checks, batches them, and processes them via GPU while the remaining verification continues. @evoskuil indicated that this method achieves about a 99.5% signature capture rate without blocking verification, thus eliminating the need for a second verification. If a batch signature check fails, the software traces it back to the corresponding block and marks that block as invalid. He also mentioned that this design can batch process an almost arbitrary number of signatures, keeping the GPU ahead of the remaining verification process and significantly shortening the full node synchronization time.

TRON recently officially released GreatVoyage-v4.8.2 (Pyrrho). The new version further enhances compatibility with Ethereum Pectra and the Osaka upgrade, adds CLZ instructions, secp256r1 signature verification precompilation, and migrates fastjson to Jackson, while unifying node monitoring metrics from InfluxDB to Prometheus.This upgrade further strengthens TRON's capabilities in smart contract compatibility, interface processing, node monitoring, and operational management. The official reminder states that this version is a mandatory upgrade, and node operators must complete the update by August 16, 2026, 23:59 (Singapore time) to avoid affecting block synchronization. The Event Plugin is also upgraded to v3.0; nodes using the official plugin must upgrade the plugin first before updating the node version; nodes using self-developed plugins should also complete adaptation as soon as possible.

Zcash has launched a new full node, Zakura, maintained by a team independent of the Zcash Foundation. It is released as a trimmed version of Zebra for fast synchronization and is compatible with the old zcashd client. This client will reach the end of its lifecycle. Zakura is one of the components of Zcash's scalability efforts, working alongside Project Tachyon and private information retrieval research, aiming to increase network throughput to Visa and Mastercard levels by reducing verification data and eliminating wallet performance bottlenecks.Zakura also supports the Ironwood (NU6.3) upgrade, which will be activated on July 28. This upgrade introduces a turnstile mechanism to limit withdrawals from the Orchard shielded pool and control the potential generation of counterfeit ZEC due to long-term soundness bugs.

Bitcoin News posted on the X platform that Dathon Pwn claims to have discovered a BIP 110 late upgrade consensus vulnerability, which may allow nodes upgrading from old software to retain chain history, while newly deployed BIP 110 nodes would reject this history, potentially leading to a hidden chain split.

Glassnode data shows that the sentiment in the BTC options market is gradually turning positive. As prices rebound, the BTC implied volatility index DVOL has decreased from 48 to 40, indicating that the panic premium accumulated in June is partially retreating. However, the current volatility is still higher than the May low, suggesting that while market uncertainty has eased, it has not completely dissipated.Meanwhile, the BTC options open interest Put/Call ratio has dropped to about 0.59, reaching a six-month low, indicating that traders are significantly reducing downside hedging and re-establishing bullish exposure. Glassnode believes that this change reflects a constructive improvement in options market sentiment.From the position structure, BTC is currently hovering around $63,000, still below the dense negative gamma range of $68,000 to $70,000. If the price further enters this range, it may trigger stronger pro-cyclical market maker hedging behavior and amplify market volatility.

Glassnode data shows that buyers who have held Bitcoin for 1-2 years have realized losses, which may indicate the bottom of the bear market in 2026, with $69,000 becoming a key price battleground.

The latest research from the Cambridge Centre for Alternative Finance shows that approximately 31% of Ethereum node activity is located in the United States, with about 39% distributed in the EU region excluding the UK, indicating that the geographical distribution of Ethereum nodes is still relatively concentrated in Western countries. The research leader, Alexander Neumuller, stated that the current node distribution is not concentrated in a single country but primarily relies on a few cloud service providers, including Hetzner, Amazon AWS, and OVH.It is noteworthy that the Ethereum network does not require half of the validators to fail for issues to arise; when more than one-third of validators go offline simultaneously, the network may be unable to complete the finalization of block checkpoints. Neumuller pointed out that nodes and validators do not have a one-to-one correspondence; a single node may run multiple validators, making it currently impossible to accurately assess the actual impact of a specific node or service provider failure on the validation network. Additionally, the research reassessed the energy consumption situation after Ethereum's Merge. The data shows that Ethereum's current annual energy consumption is approximately 7.9 GWh, equivalent to about 1 megawatt of continuous power, which is only about 0.02% of the pre-Merge level, with energy consumption decreasing by approximately 99.98%. Currently, the proportion of sustainable energy used by the Ethereum network exceeds 56%, higher than the global average. The research also pointed out that the concentration of client software is another potential risk; if a dominant client has a vulnerability, it could affect a large number of network participants. The report was published by the Cambridge Centre for Alternative Finance, with support from the Ethereum Foundation.

According to the latest "Bitcoin Weekly Market Pulse" report published by glassnode, although BTC has rebounded after a recent sell-off, this round of increase is still closer to a "volume contraction recovery." The report shows that the weekly spot trading volume decreased by 21.5% to $4.1 billion, and the spot CVD turned from positive to negative at -$58.8 million, indicating that the breadth of market buying remains weak.In terms of institutional funds, the weekly net inflow of the US spot BTC ETF has recovered to $161.3 million, but ETF trading volume still decreased by 11.97% to $8.4 billion. On-chain data shows that the number of active addresses decreased by 7.6% to 599,000, on-chain transfer volume decreased by 16.1% to $4 billion, and total fees decreased by 13.9% to $168,400, indicating that on-chain activity continues to weaken.In terms of derivatives, the futures funding rate increased by 13.4% to $1.9 million, but the perpetual contract CVD plummeted by 81.7% to $83.9 million; at the same time, the options market 25-Delta Skew rose to 18.87%, indicating that investors still maintain strong demand for downside protection during the rebound process.

According to CoinDesk, the Ethereum Foundation recently disclosed that its security team used AI agents to test the software running on Ethereum validator nodes and successfully discovered a remotely triggerable vulnerability that could cause node crashes. However, researchers emphasized that human review remains a key step in distinguishing real vulnerabilities from false positives among the large number of security reports generated by AI.It is reported that the discovered vulnerability exists in the Ethereum network message propagation protocol gossipsub, where an attacker can remotely trigger the node software to enter an abnormal computation state, causing the program to crash and shut down, making the validator node go offline until the operator manually restarts it. This vulnerability has been fixed and registered under the identifier "CVE-2026-34219."Nikos Baxevanis, a member of the Ethereum Foundation's protocol security team, stated that what was truly surprising about this incident was not the AI's ability to discover vulnerabilities, but rather the amount of time the team spent discerning which vulnerabilities were real and which were merely seemingly credible "illusions."

According to The Block, the latest report "Merged Ethereum" released by the Cambridge Centre for Alternative Finance (CCAF) shows that approximately 31% of Ethereum node activity is located in the United States, and 39% is distributed across the European Union (excluding the UK), presenting an overall Western centralization pattern.The report points out that there are potential centralization risks in the Ethereum network—nodes are highly concentrated among three major hosting service providers: Hetzner, AWS, and OVH. If more than one-third of the validators go offline simultaneously, the network checkpoints will stop finalizing.In addition, the report recalculated Ethereum's energy consumption, estimating that the annual electricity usage after the merge is about 7.9 gigawatt-hours, a decrease of approximately 99.98% compared to before the merge, with sustainable energy accounting for over 56%. The cost needed to offset its annual carbon emissions is only about $33,500 to $73,800.

According to CoinDesk, the new version of the XRP Ledger server software v3.2.0 has been launched, aiming to reduce operational costs, enhance stability, and increase appeal to institutional users. Currently, about 43% of the approximately 833 active nodes are running the new version, while 51% are still using the old version v3.1.3. However, about 89% of the 35 validators in the default UNL have upgraded, reaching the required 80% threshold for activation.The security amendment fixCleanup3_2_0 associated with the software upgrade is still under independent voting, covering fixes and improvements for single-asset vaults, permissioned DEX, multi-purpose tokens, and lending protocols, with current support far below the software adoption rate. Ripple has voted in favor of this amendment, and validators that do not upgrade before the amendment is activated may face the risk of being cut off from the Ledger.

The New Hampshire House Bill HB639 has completed the registration process. The bill specifies that state and local governments may not restrict individuals from using digital assets for payments or holding assets through self-custody wallets, nor may they impose additional taxes solely for the use of digital assets.At the same time, individuals or businesses operating nodes, engaging in mining or staking activities, are not required to obtain a money transmission license, and such activities are not considered the issuance or sale of securities.

Michael Saylor posted on the X platform, stating that the future of Bitcoin is shaped by the dynamic consensus among nodes, miners, and holders. Among these, the influence of nodes is reflected in transaction validation rights, miners are represented by computing power, and holders are represented by economic weight. Only when validation, security, and capital align can protocol changes be approved.He further pointed out that while the forces of brands, laws, politics, technology, institutions, culture, and the physical realm may influence discussions related to Bitcoin, they cannot directly determine the outcome of consensus. Their role is mainly reflected in persuading, coordinating, constraining, or mobilizing nodes, miners, and holders.

According to CoinDesk, Glassnode data shows that Bitcoin long-term holders have shifted from net distribution to net accumulation, with the 30-day net position change turning positive, and the current net accumulation scale is between 50,000 to 100,000 BTC. Glassnode points out that the ongoing shift from net distribution to net accumulation among long-term holders typically occurs during periods of market weakness, as long-term investors gradually increase their holdings while short-term participants reduce risk. In terms of accumulation trend scores, the smallest holders (less than 1 BTC) score close to 0.8 to 0.9, medium-sized holders (100 to 1,000 BTC) are also close to that range, while the groups of 1 to 10 BTC and 10 to 100 BTC score around 0.6 to 0.7, and the group of 1,000 to 10,000 BTC scores about 0.5 to 0.6, with the largest whales (over 10,000 BTC) still close to neutral. Glassnode indicates that synchronized accumulation across multiple wallet sizes is a positive signal, but the largest holders have not yet started buying, and further observation is needed to confirm the overall accumulation trend.

According to a report released by the data analysis platform Glassnode (@glassnode), although the BTC price is still far below its historical high, traders on the Hyperliquid platform are continuously increasing their long positions, with a buy-the-dip sentiment prevailing throughout the downward trend, and the potential for market short squeezes is continuously accumulating.Meanwhile, the altcoin cycle signal has returned to "altcoin season," and the selling pressure on altcoins is tending to exhaust, but BTC is still under downward pressure, and the current market trend is still dominated by BTC movements.

The official announcement from the XAUT ecosystem states that the Greater China region node will officially complete its network connection from June 15 to 20, fully integrating into the global node network, simultaneously connecting the WEFI payment system and DEO Banking digital banking, completing the critical expansion of global financial infrastructure.The core focus of this ecological upgrade is on three major tracks: global stablecoin payments, on-chain asset clearing and settlement, and one-stop digital banking services. The dual asset pledge system for USDC and USD1 will be launched simultaneously, with multiple measures running in parallel to comprehensively optimize the underlying liquidity of the ecosystem, user asset allocation efficiency, and cross-border payment flow capabilities.According to official disclosures, the network upgrade of the Greater China region node will link with Helio Protocol's global investment ecosystem resources, implement XAUT gold stablecoin payment scenarios, diversify digital financial services, and establish a global node collaborative operation system, continuously improving the underlying architecture of the global stablecoin payment network, laying a solid foundation for the digitization of gold assets, cross-border compliant payments, and the large-scale implementation of on-chain banking services.

Glassnode data shows that the 30-day moving average of BTC treasury company's total trading volume has decreased from $34.2 billion/day in December 2025 to the current $17.4 billion/day, a 49% drop in six months.Glassnode points out that the speculative interest in DAT stocks is highly correlated with BTC prices. As spot prices pull back, interest in gaining leveraged Bitcoin exposure through listed treasury tools has also weakened, and trading activity has halved from its peak.

Glassnode released a market weekly report stating that Bitcoin continues to exhibit characteristics of a late-stage adjustment, with recent buyers suffering significant losses and realized losses remaining high, while several major sources of demand have weakened considerably.The drop in Bitcoin's price to around $60,000 triggered a significant deleveraging event, clearing a large number of speculative positions from the market. While this helps reset leverage levels, spot demand has yet to show a substantial recovery. The options market remains defensive, with implied volatility staying high, strong demand for downside protection, and traders' positions concentrated around the current spot levels. Coupled with a decline in institutional participation and a slowdown in corporate bond accumulation, these data indicate that risk appetite remains subdued.Overall, the market seems to be further entering a phase of capitulation. Although leverage has essentially been reset and valuation metrics have reached historical lows, the demand response typically associated with long-term market lows has yet to materialize.

Glassnode co-founder Rafael posted an analysis of the recent Bitcoin price trend on the X platform, noting that the current Bitcoin price is in the $62,000 range, having dropped nearly 50% from its all-time high, with a decline of 24% over the past month. The price has crossed the upper range of its pricing framework, entering a valuation cluster area where historical cycles have previously shown bottoms.Rafael further pointed out that market bottoms cannot be confirmed in advance and can only be defined through probability ranges and key price levels to identify potential bottom signals. Bitcoin has fallen below the median holder breakeven line for the first time since December 2022, currently situated within a broader support range: the median realized price is approximately $64,100, and the 200-week moving average price is around $61,700.The current high-probability bottom range may be between $46,000 and $54,000, with a rare "sell-off tail" below that range of $35,000 to $40,000. It is important to note that the magnitude of cyclical pullbacks is gradually decreasing: previous rounds of lows saw declines of about 85%, 84%, and 77%, while this round has only dropped about 50%, indicating that a high-probability bottom is more likely to be in the upper range, though extreme sell-off possibilities cannot be ruled out.
