Avalanche is an open-source platform for launching decentralized applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. Avalanche is the first smart contracts platform that processes 4,500+ transactions/second and instantly confirms transactions. Ethereum developers can quickly build on Avalanche as Solidity works out-of-the-box.
A key difference between Avalanche and other decentralized networks is the consensus protocol. Over time, people have come to a false understanding that blockchains have to be slow and not scalable. The Avalanche protocol employs a novel approach to consensus to achieve its strong safety guarantees, quick finality, and high-throughput, without compromising decentralization.
AVAX is the native token of Avalanche. It’s a hard-capped, scarce asset that is used to pay for fees, secure the platform through staking, and provide a basic unit of account between the multiple subnets created on Avalanche. 1 nAVAX is equal to 0.000000001 AVAX.
Protocols in the Avalanche family operate through repeated sub-sampled voting. When a validator is determining whether a transaction should be accepted or rejected, it asks a small, random subset of validators whether they think the transaction should be accepted or rejected. If the queried validator thinks the transaction is invalid, has already rejected the transaction, or prefers a conflicting transaction, it replies that it thinks the transaction should be rejected. Otherwise, it replies that it thinks the transaction should be accepted.
If a sufficiently large portion (alpha
The validator repeats this sampling process until alpha of the validators queried reply the same way (accept or reject) for beta
In the common case when a transaction has no conflicts, finalization happens very quickly. When conflicts exist, honest validators quickly cluster around conflicting transactions, entering a positive feedback loop until all correct validators prefer that transaction. This leads to the acceptance of non-conflicting transactions and the rejection of conflicting transactions.
It is guaranteed (with high probability based on system parameters) that if any honest validator accepts or rejects a transaction, all honest validators will accept or reject that transaction.

Snowman is a chain-optimized consensus protocol–high-throughput, totally-ordered, and great for smart contracts. Snowman is powered by the Avalanche consensus protocol. Both P-Chain and C-Chain implement the Snowman consensus protocol.
Uses a novel consensus protocol, developed by a team of Cornell computer scientists, and is able to permanently confirm transactions in under 1 second.
Capable of 4,500 transactions per second–an order of magnitude greater than existing blockchains.
Ensures stronger security guarantees well-above the 51% standard of other networks.
Easily create custom blockchains and decentralized apps that contain almost any arbitrary logic.
Uses energy-efficient proof-of-stake consensus algorithm rather than proof-of-work.
Supports the creation of Solidity smart contracts and your favorite Ethereum tools like Remix, Metamask, Truffle, and more.
Create your own public or private blockchains.
Native support for easily creating and trading digital smart assets with complex, custom rulesets.
