Bitcoin Mempool Linearization
Arman Mollakhani, Pieter Wuille, Dongning Guo
In the Bitcoin system, transactions arrive continuously at miners' mempools and await inclusion in future blocks. Every non-coinbase transaction must spend one or more unspent outp…
Inter-Satellite Link Optimization for Low-Latency Global Networking
Arman Mollakhani, Jerayu Tiamraj, Shu-Jie Cao +1
Large-scale low-Earth-orbit satellite constellations offer a promising platform for global low-latency networking, aided by faster propagation in free space than in fiber and coppe…
Inter-Satellite Link Configuration for Fast Delivery in Low-Earth-Orbit Constellations
Arman Mollakhani, Jerayu Tiamraj, Shu-Jie Cao +1
End-to-end latency in large low-Earth-orbit (LEO) constellations is dominated by propagation delay, making total delay roughly proportional to the network diameter, the longest sho…
Fault-Tolerant Spectrum Usage Consensus for Low-Earth-Orbit Satellite Constellations
Arman Mollakhani, Dongning Guo
Operators of low-Earth-orbit (LEO) non-geostationary satellite networks, also known as mega-constellations, are required by current regulations to share all available satellite spe…
