Blockchain,like any other complex technology,needs a strong testing methodology to support its evolution in both research and development *** up meaningful tests for permissionless blockchain technology is a notoriously complex task for several reasons:software is complex,a large number of nodes are involved,the network is non-ideal,*** usually adopt small virtual laboratories or costly real devnets based on real *** usually prefer simulations of a large number of nodes based on simplified *** this paper,we aim to obtain the advantages of both approaches,i.e.,performing large,realistic,inexpensive,and flexible experiments,using real blockchain software within a virtual *** do that,we address the challenge of running large blockchain networks in a single physical machine,leveraging Linux and *** analyze a number of problems that arise when large blockchain networks are emulated,and we provide technical solutions for all of ***,we describe two experiences of emulating fairly large blockchain networks on a single machine:adopting both research-oriented and production-oriented software and involving more than 3000 containers.
