Avalanche

Avalanche is a proof-of-stake network built as several purpose-built chains rather than one general-purpose ledger, with a maximum supply of 720 million AVAX. Its distinguishing idea is the subnet: any group can launch an independent chain with its own rules, validator set and virtual machine, while still using AVAX for staking.

Three chains, three jobs

The platform separates asset transfers, smart contracts and validator coordination into distinct chains, each optimised for its task. Most networks force one ledger to serve every purpose and accept the compromises; splitting them means the contract chain can be EVM-compatible while asset transfers stay simple and fast.

Subnets are the strategic bet

A subnet is a sovereign chain with its own validators and rules, which is what makes Avalanche viable for institutions that need permissioned participants or jurisdiction-specific compliance. The trade is that a subnet inherits only the security its own validators provide — being on Avalanche does not confer the main network's security.

Consensus by repeated random sampling

Rather than every validator communicating with every other, each repeatedly polls a small random sample of peers until confidence converges. This scales to large validator counts without the messaging overhead of classical Byzantine agreement, and it delivers finality in seconds rather than probabilistic confirmation.

Fees are burned, supply is capped

Transaction fees are destroyed rather than paid to validators, so activity reduces supply against a hard 720 million cap. Validators are compensated through staking rewards drawn from the remaining unissued supply, which puts a defined end to issuance.

Who it is for

Avalanche suits applications that want EVM compatibility with fast finality, and institutions that need a chain they control without building consensus from scratch. The open question is whether subnet sovereignty fragments liquidity faster than it attracts deployments.
