The LBM SDK is a framework for building blockchain applications in Golang.
It is being used to build LBM, the first implementation of the LINE Blockchain Mainnet.
This is forked from cosmos-sdk at 2021-03-15.
WARNING: Breaking changes may occur because this repository is still in the pre-release development phase.
Note: Requires Go 1.15+
What is the LBM SDK?
The LBM SDK is an open-source framework for building multi-asset public Proof-of-Stake (PoS) blockchains, as well as permissioned Proof-Of-Authority (PoA) blockchains. Blockchains built with the Cosmos SDK are generally referred to as application-specific blockchains.
The purpose of LBM SDK is to succeed to the objectives of Cosmos sdk while helping develop blockchains that requires faster transaction processing to be applied to reality.
Why the LBM SDK?
Cosmos-sdk, which created the philosophy of application-specific blockchain, established its status as a framework for various application blockchain development. LBM SDK inherited this cosmos-sdk philosophy, addressing slow transaction processing problem that was difficult for cosmos-sdk to apply in real financial system. Real financial systems require thousands of processing performance per second, with LBM SDK adding many performance improvements to meet that demand.
The following work was carried out to improve performance.
- Concurrent checkTx, deliverTx
- Use fastcache for inter block cache and nodedb cache of iavl
- Lock granularity enhancement
In addition, the following functions were added:
- Virtual machine using
cosmwasmthat makes smart contracts possible to be executed - Use Ostracon as consensus engine instead of
Tendermint
To learn about Cosmos SDK, please refer Cosmos SDK Docs.
Quick Start
Build
make build
make install
# you can see the version!
simd version
Configure
zsh init_node.sh sim {N(number of nodes), default=1}
Run
# run a node
simd start --home ~/.simapp/simapp0
# If N is larger than 1, run all node.
# simapp0 has other nodes as persistant_peer.
simd start --home ~/.simapp/simapp0
simd start --home ~/.simapp/simapp1

unknownproto
unknownproto implements functionality to "type check" protobuf serialized byte sequences against an expected proto.Message to report: a) Unknown fields in the stream -- this is indicative of mismatched services, perhaps a malicious actor b) Mismatched wire types for a field -- this is indicative of mismatched services Its API signature is similar to proto.Unmarshal([]byte, proto.Message) in the strict case if err := RejectUnknownFieldsStrict(protoBlob, protoMessage, false); err != nil { // Handle the error.
