QLDB was proposed by Amazon's DistSys experts as a replacemnent for Private/Permissioned DLT/Blockchains.<p>Now they're suggesting to replace it with Postgres.<p>Conclusion: you don't need a Blockchain - use Postgres ;)
Interesting that AWS is shutting down services. Didn't think that was something they did.<p>The article does mention OpsWorks which I knew they were reducing support for but didn't realise they were shutting down too.
