first_img Zakura released the experimental P2Pv2, and the testnet is now running in dual stack

Zakura has announced an experimental network layer P2Pv2 for Zcash nodes, intended to replace the old protocol inherited from Bitcoin. This layer combines high-throughput networking, resource control, and a consensus engine tested for properties, allowing developers to add services without permission. Zakura states that approximately 50,000 transactions per second require each full node to continuously receive about 100MB/s of block data, while the 25-second block of NU7 can carry a maximum of 2MB, with existing network throughput differing by more than a thousand times from this rate. Tachyon can reduce the proof after entering the block, but the network still needs to propagate a large number of individual transactions.P2Pv2 replaces the protocol stack from about a decade ago with protocols that can be optimized for latency, throughput, or robustness, allowing a secure connection to carry multiple independent services. The transport layer uses its own zakura-quic, based on quinn-proto, utilizing QUIC and TLS 1.3, and authenticating peers with Ed25519 node identity. Related changes remove the dependency on Iroh, allowing nodes to configure socket buffers, flow control windows, timers, and connection admission before the TLS handshake. The new transport directly connects to peer addresses without using relays, external address lookups, automatic port mapping, or QUIC NAT traversal. Nodes sign identities, addresses, protocol scopes, and service IDs, allowing clients to find peers based on specific services.The independent component zakura-header-chain verifies block headers and retains competing branches in a directed acyclic graph, selecting the best qualified chain. Block synchronization schedules requests based on the delivery rates measured by each peer, and a verified commitment tree is used to skip the reconstruction of Sapling, Orchard, and Ironwood trees for each block. Currently, the Mainnet still defaults to the old P2P stack, while the Testnet and Regtest run dual stacks by default, with the native protocol version being p2p-v2/3. Zakura notes that P2Pv2 still has known denial-of-service risks and has not yet become a hardened trust boundary; production hardening, resource control, and block relay protocols are still in progress.

Gate Launchpool's three major activities are running simultaneously, and the MarsCat (MCAT) prize pool exceeds one million dollars

According to official news, the Gate Launchpool Phase 375 MarsCat (MCAT) event is currently underway and will last until September 24 at 20:00 (UTC+8). Users can stake USDT, GT, or MCAT to share 2,000,000 MCAT tokens for free, with the current prize pool exceeding one million dollars. Among them, the total amount of USDT staked has reached 83,708,714.6 USDT, with an estimated annualized return rate of 13.69%; the estimated annualized return rate for the GT staking pool is 174.53%; and the estimated annualized return rate for the MCAT staking pool is 7522.57%.In addition, the Gate Launchpool CP and ALIGN events are simultaneously ongoing, with three major Launchpool activities running in parallel, providing users with diverse staking options. In the Gate Launchpool CP event, the total amount of ETH staked has reached 15,974.39 ETH, with an estimated annualized return rate of 3.15%; the estimated annualized return rate for the BTC staking pool is 1.41%; and the estimated annualized return rate for the CP staking pool is 61.65%. In the Gate Launchpool ALIGN event, the total amount of USDT staked has reached 137,165,777.41 USDT, with an estimated annualized return rate of 4.76%; the estimated annualized return rate for the GT staking pool is 0.96%; and the estimated annualized return rate for the ALIGN staking pool is 116.85%.

first_img Hyperscale Data has stopped Bitcoin mining in Michigan, and its Bitcoin holdings have shrunk by about 79%

The U.S. publicly traded company Hyperscale Data has terminated all Bitcoin mining operations at its Michigan facility to convert the site into infrastructure for artificial intelligence data center clients. The company stated on Wednesday that all Bitcoin mining machines in the facility have been shut down following an inspection by an unnamed California neocloud provider, and plans to sell the related mining equipment.Hyperscale Data stated that the client has signed a 10-year master service agreement, contracting 20 megawatts (MW) of AI computing power, with two optional extensions of 5 years each. The company estimates that this agreement could generate over $1.2 billion in revenue over the maximum 20-year term, and if the client exercises an additional 32 MW option, potential revenue could exceed $3 billion, while the site is expected to ultimately support 340 MW. However, the company also cautioned that its expansion plans are still in the preliminary stages and depend on financing, approvals, and other risks.Meanwhile, Hyperscale has significantly reduced its Bitcoin holdings to fund AI construction. Affected by the company's completion of a four-for-one reverse stock split and other factors, its stock price closed at $0.1984 on Wednesday, down about 17%, marking a record low adjusted for the stock split. According to BitcoinTreasuries.NET data, the company currently holds approximately 215 Bitcoins, valued at about $16.7 million, a decrease of about 79% from around 1,006 at the end of July, ranking 84th among publicly traded companies tracked on the platform.
