EVMx: An FPGA-Based Smart Contract Processing Unit
Ethereum blockchain uses smart contracts (SCs) to implement decentralized applications (dApps). SCs are executed by the Ethereum virtual machine (EVM) running within an Ethereum client. Moreover, the EVM has been widely adopted by other blockchain platforms, including Solana, Cardano, Avalanche, Polkadot, and more. However, the EVM performance is limited by the constraints of the general-purpose computer it operates on. This work proposes offloading SC execution onto a dedicated hardware-based …

High-dimensional programmable photonic circuits with structured media
Photonic circuits provide a powerful platform for manipulating optical modes in both classical and quantum regimes. Here, we report a programmable free-space photonic architecture capable of implementing high-dimensional unitary transformations with translational symmetry. Information is encoded in structured light modes defined by circular polarisation and quantised transverse momenta, and processed using a cascade of three spatial light modulators interleaved with half-wave plates. We demonst…
