HashKey2026-10-12 06:54:08HashKey says some USD fiat deposit and withdrawal channels delayed over U.S. holidayHashKey Exchange said some fiat deposit and withdrawal channels in Hong Kong are being affected by the U.S. Columbus Day holiday. According to the exchange, USD fiat deposits and withdrawals through RTGS, the local payment network, and TT wire transfers have been temporarily suspended, with transactions remaining pending for now. Bank processing is scheduled to resume on Tuesday, Oct. 13, 2026, and settlement may also take longer than usual. HashKey said other services will continue to operate during the holiday period. FPS, or the Faster Payment System, eDDA, and Book Transfer remain available and support Hong Kong dollar, U.S. dollar, offshore renminbi, and euro transactions. The exchange advised users to prioritize FPS, eDDA, or Book Transfer for fiat top-ups during the holiday window in order to keep funds moving more efficiently.

blockchain sc2026-05-29 12:00:11An In-depth Look at Blockchain Scalability: Three Paths to Break Through Transaction Speed BottlenecksBlockchain scalability remains the holy grail and primary bottleneck for cryptocurrency adoption, with Bitcoin processing only 7 transactions per second (TPS) and Ethereum 20-30 TPS, compared to Visa’s 24,000 TPS. The three core bottlenecks are throughput, finality, and confirmation time. The scalability trilemma—coined by Vitalik Buterin—posits that networks can only achieve two of scalability, decentralization, and security, though it is not an unbreakable law. This article explores three main directions for tackling scalability: on-chain solutions like SegWit and sharding, off-chain solutions such as sidechains and payment channels, and alternative consensus mechanisms including Nakamoto-style, classical, and leaderless approaches. By examining each in detail, we provide a comprehensive overview of the current frontier in blockchain scaling, from theoretical concepts to real-world implementations like Lightning Network, Plasma, and Avalanche.1120
Bitcoin2026-05-29 12:00:11Bitcoin Lightning Network: The Complete Guide to Instant, Low-Cost Off-Chain PaymentsThe Lightning Network is a Layer-2 payment protocol built atop Bitcoin to resolve its scalability bottlenecks. By using bi-directional payment channels, transactions can be processed off-chain—achieving near-instant settlement and extremely low fees. This comprehensive guide explains Bitcoin's throughput and cost limitations, the mechanics of channel opening, transacting, and closing, the routing system that enables multi-hop payments across the network, and the critical role of Hashed Timelock Contracts (HTLCs) in securing trustless transfers. We also examine current challenges related to routing reliability, channel liquidity, and attack vectors, along with recent real-world adoption by firms like MicroStrategy and Strike.1110
Bitcoin2026-05-28 03:00:22Understanding the Lightning Network: How Bitcoin's Layer-2 Payment Protocol Enables Instant TransactionsThe Lightning Network is a Layer-2 payment protocol built on the Bitcoin blockchain, enabling near-instant micropayments through bi-directional payment channels. Designed to tackle Bitcoin's scalability challenges—such as 10-minute block times, limited throughput of about 7 transactions per second, and high fees that peaked above $60 in April 2021—it allows users to transact off-chain with extremely low costs. This guide explains the history of the Lightning Network from its proposal in 2016, the activation of SegWit in 2017, to its mainnet launch in 2018. It details the mechanics of opening, transacting within, and closing channels, as well as multi-hop routing using source and onion routing and hashed timelock contracts (HTLCs). Today, the network has around 16,000 active nodes, but faces routing issues, liquidity shortages, and security vulnerabilities. Nonetheless, industry adoption continues: MicroStrategy is working on Lightning solutions, and Strike has launched remittance services in the Philippines powered by the Lightning Network. The article covers key concepts, practical examples, and the current state of this evolving technology.2000
