Substrate is a modular Rust framework for building application-specific blockchains. It includes production consensus components such as BABE and GRANDPA and supports custom runtime logic.
Top 6 Substrate alternatives
Tendermint is an open-source Byzantine fault-tolerant consensus engine for replicated state machines and application-specific blockchains. It was widely used by Cosmos-based developers,...
Pros
- Simple ABCI interface separates consensus from application logic
- Fast deterministic finality compared with proof-of-work chains
- Mature Go implementation with extensive blockchain ecosystem adoption
Cons
- Legacy project with active development moved to CometBFT
- Requires validator governance and a fixed validator set
- Less suitable than Ethereum clients for public smart-contract ecosystems
Free, open source

Solana is a high-performance blockchain platform known for its fast transaction speeds and low fees. It aims to support high-volume decentralized applications.
Pros
- Fast transaction speeds
- Low fees
- High-performance
Cons
- Less mature ecosystem
- Limited tooling
Hyperledger Besu is an open-source Ethereum client developed under the Hyperledger umbrella.
Pros
- Enterprise-focused features
- Interoperability with permissioned networks
- Modular architecture
Cons
- Steep learning curve
- Requires Java runtime

Hedera
Hedera Governing Council
Hedera is a public distributed network using hashgraph consensus for payments, tokenization, smart contracts, and enterprise applications. It provides native token, consensus,...
Pros
- Predictable low fees are attractive for enterprise workloads
- Native token and consensus services reduce custom-contract requirements
- Fast finality and high throughput exceed NEM's typical positioning
Cons
- More governed and less permissionless in perception than NEM
- Smaller grassroots developer ecosystem than Ethereum
- Hashgraph architecture differs substantially from conventional blockchains
Free; network fees paid in HBAR
6
AvalancheGo
Ava Labs
AvalancheGo is the open-source node implementation for Avalanche networks and custom subnets. It provides Avalanche consensus protocols, validator infrastructure, and support for...
Pros
- Offers fast probabilistic finality and high validator scalability
- Supports custom networks with Ethereum Virtual Machine compatibility
- Provides a broader managed ecosystem than a standalone consensus engine
Cons
- More tightly coupled to Avalanche's network architecture than Tendermint
- Consensus guarantees differ from Tendermint's deterministic BFT model
- Public network operation involves token economics and transaction fees
Free, open source; network fees apply
