  "abstract": "The Bustling Universe Radio Survey Telescope in Taiwan (BURSTT) is a radio interferometer array designed for surveying fast radio bursts (FRBs) in the nearby Universe with a wide instantaneous field of view (FoV) of $\\approx$6000 deg$^2$ and precisely localizing them with sub-arcsecond angular resolution. The first phase of BURSTT, BURSTT-256, consists of a main antenna array comprising 256 log-periodic dipole antennas (LPDAs) observing at 400-800 MHz for real-time beamforming and FRB search, currently with 256 beams covering $\\approx$ 3200 deg$^2$ FoV, together with several smaller outrigger stations with 16-64 antennas and separated by $\\mathcal{O}(10^2 - 10^3)$ km baselines for joint observations to localize FRBs using very-long baseline interferometry. This work presents the design, deployment, and commissioning of the BURSTT-256 main array, including site selection, radio-frequency (RF) background characterization, receiver antenna array and RF front-end, as well as real-time, factorized digital beamforming backend that currently generates 256 beams. The system's on-sky performance, sensitivity, and beamforming fidelity have been calibrated through observations of bright celestial calibrators. The antenna array in the initial phase using commercial LPDAs has a system equivalent flux density of $\\approx$11 kJy, and is expected to achieve $\\approx$4 kJy using custom-design LPDAs after optimization in late 2026. BURSTT-256 serves as a critical pathfinder for future expansion of the array to 2048 elements and beyond, operating at 300-700 MHz with $\\approx$6000 deg$^2$ FoV. It establishes the framework required to discover and localize nearby FRBs with sub-arcsecond precision. By substantially increasing the number of well-localized nearby FRBs, BURSTT will facilitate multi-wavelength and multi-messenger counterpart identification, helping to unveil the elusive origin of FRBs.",
