Based on feedbacks gathered earlier, we are revising our verification model with the following changes: * When validating a transaction, CKB will grab all lock scripts from all inputs, and group them based on lock script hash. The script in each group will only be run once. The lock script itself will have to do the validation task for all inputs in the same group * CKB will also grab all type scripts from inputs and outputs(notice different from previous version, the type scripts in inputs are included here as well), and group them based on type script hash as well. Each type script in each group will also be run once. The type script itself needs to handle the validation task within the group * Syscalls are also revised to allow fetching all the inputs/outputs/witnesses within a single group. The default secp256k1_blake160_sighash_all lock script is compiled from the following source: https://github.com/nervosnetwork/ckb-system-scripts/blob/e00ba451dccb7a516454ea9606de3a21c8f9a80c/c/secp256k1_blake160_sighash_all.c The exact gcc version used in the compilation can be located in the following docker image: xxuejie/riscv-gnu-toolchain-rv64imac:20190529
