Hyperledger team just announced a new version of Burrow is available now to download on Github. This version has the following fixes and new features.
- Burrow deploy creates devdoc
- Docker image has org.label-schema labels
- Upgraded to Tendermint 0.23.0
- Validator Set Power now takes Address
- RPC/TM config renamed to RPC/Info
- Upgrade to IAVL 0.10.0 and load previous versions immutably on boot - for chains with a long history > 20 minute load times could be observed because every previous root was being loaded from DB rather than lightweight version references as was intended
- Metrics server does not panic on empty block metas and recovers from other panics
From the announcement -
Hyperledger Burrow is built to be a unitary binary, and a fast, lightweight and easy to get to grips blockchain framework. Over the past year Hyperledger Burrow has been refactoring itself into an even lighter and more agile network platform – and with the new v.0.21.0 it’s starting to really fire on all four cylinders. The latest version can be downloaded from here.
We have integrated a number of abstractions with the goal of making it even easier for developers looking to leverage the Ethereum Virtual Machine in a permissioned context to get started with the actually important aspect of building any business-for blockchain use case: namely the business logic encoded in the smart contract layer.
This release and the others preceding it make some landmark improvements to the Burrow architecture, both in its tool and the node itself. Most notable amongst these refinements are:
Rewiring with protobuf types and GRPC interfaces across the board to facilitate robust integration points and RPC layers (replacing previous multiple RPCs)
Addition of a powerful ETL / execution event service to drive downstream services from smart contract events and to populate queriable datasets from smart contract objects
An integrated and harmonized key-signing daemon that can perform as a key-holding delegate for other services
Massively improved burrow helm charts for Kubernetes which increase the flexibility and ease of booting complex networks within the popular container orchestration system.
Bos (Monax’s deployment tool) has now been integrated as part of Burrow Deploy. Significantly, this includes an Apache2 licenced ABI which we architected from scratch to the Ethereum community’s specification. This enables various Hyperledger projects to build Ethereum smart contract aware systems.
