Bloom Technology, a blockchain development company, has successfully completed a large-scale public test for its next-generation high-performance public blockchain platform, Locus Chain.
This test marks the first large-scale trial since the project’s inception in 2018 and the groundbreaking announcement of Dynamic Sharding in 2020. Designed to replicate real-world network conditions, such as increased transaction volumes and an expanded number of nodes, the test aimed to validate the practical performance of Dynamic Sharding, one of Locus Chain’s three core technologies.
During the test, Locus Chain demonstrated stable processing speeds with no degradation in network performance, even as transaction volumes increased, meeting its original design objectives. While Locus Chain was initially designed to handle 1,000 to 5,000 nodes per shard, the number of nodes per shard was reduced during this test to ensure reliable shard division verification.
In a 32-shard environment, Locus Chain achieved over 1,000 TPS (Transactions Per Second), processing transactions at high speeds within 0.1 to 3 seconds. Token transactions generated on the chain network were also processed with the same efficiency. Achieved in real-world conditions rather than controlled experimental environments, these results establish a robust technological foundation for practical applications across industries requiring blockchain, far surpassing existing blockchains limited to token management and transfers. Furthermore, even with sharp increases in TPS, latency consistently remained between 0.1 and 3 seconds, highlighting Locus Chain’s distinct advantages over traditional blockchain technologies.
During the test, Locus Chain consistently maintained an average network bandwidth of less than 5 Mbps per node, even while surpassing 1,400 TPS. This achievement highlights the platform’s capability to support decentralized digital industries requiring high-speed, large-scale data processing, such as gaming, video streaming, DeFi, mobility data management, AI systems, and authentication services. In comparison, current public blockchains prioritizing speed require node bandwidths ranging from 500 Mbps to 10 Gbps, yet their actual TPS performance averages only around 1,000 TPS.
Notably, Locus Chain plans to implement “Cubic Sharding” as the number of nodes increases, enabling the use of up to 4,096 shards. With this advanced sharding system, the network could handle hundreds of thousands of TPS even at a minimal bandwidth of 5 Mbps. By simply increasing bandwidth, the platform can achieve unparalleled and stable TPS performance. Leveraging this technological edge, Locus Chain aims to position itself as a cornerstone infrastructure for the decentralized internet era, accommodating massive processing loads through tens of thousands of nodes after the mainnet launch.
Sang-Yoon Lee, CEO of Bloom Technology, stated, “Locus Chain is the first blockchain in the industry to develop fully operational Dynamic Sharding to achieve complete decentralization. It is designed to enable anyone to easily and conveniently configure nodes using IoT and mobile devices. With the first-stage shard system comprising 64 shards and 64,000 nodes, Locus Chain can deliver over 4,000 TPS at a minimal bandwidth of just 5 Mbps, ensuring seamless user experiences.” He added, “If the network bandwidth per node is increased to 20 Mbps, it can achieve over 16,000 TPS, showcasing Locus Chain’s potential to enable new decentralized IT services that surpass traditional centralized systems, something previously unattainable with conventional blockchains.”
Seok-Bin Yoon, Director of the Korea Blockchain Association (Special Professor at Sogang University’s Graduate School of Information and Communications/CEO of Trust Connector), remarked, “Achieving 1,400 TPS with fully decentralized 32-shard division and an average bandwidth of only 5 Mbps per node is nothing short of extraordinary. I believe Locus Chain has the potential to become a blockchain project that not only represents South Korea but also sets a global standard,” sharing his thoughts on the test results.
Locus Chain demonstrated its technological prowess in mobile environments through this test. With minimal network usage and highly optimized nodes of approximately 50 MB, Locus Chain supports node operation on low-spec devices such as smartphones, Raspberry Pi, and internet routers. This capability makes it possible to implement decentralized processing without servers, not only for mobile games and applications—where frequent network disruptions and fast re-syncing are critical—but also for mobility services like autonomous vehicles, robots, and drones.
In 2023, Locus Chain successfully integrated its decentralized Locus Gamechain into the online game Kingdom Under Fire without the need for servers. This was achieved with minimal CPU usage and low bandwidth requirements while maintaining optimal game performance. The game is now available on STEAM, a global game publishing platform. Additionally, on December 2 and 3, the Web3 gaming/metaverse platform CRETA conducted a global CBT (Closed Beta Test), showcasing ultra-realistic (photo-realistic) games, multimedia content, and AI services powered by Unreal Engine and implemented through the Locus Gamechain. The test demonstrated robust and stable technology to players around the world.
Sang-Yoon Lee, CEO of Bloom Technology, commented, “This large-scale test has demonstrated that Locus Chain is a public blockchain capable of delivering exceptional scalability in a fully decentralized environment. Building on these positive results, we will intensify efforts to further enhance our technology.” He continued, “Locus Chain will play a pivotal role in creating safer, more efficient, and transparent digital ecosystems across a wide range of industries and applications. These include DeFi financial platforms, metaverses, Web3 gaming platforms, video streaming, mobility device data management, and AI data authentication and management solutions.”
