æternity blockchain is an Erlang-based scalable smart contract platform engineered by programming pioneers to address some of the most fundamental challenges native to earlier blockchains. By redesigning blockchain technology at the protocol level, the æternity developer community has enabled the core protocol to understand and integrate a rich set of functionalities out of the box.
æternity smart contract programming is unique: Sophia is a typed functional programming language in the ML family that makes it easier to write correct programs.
The Fast æternity Transaction Engine, or FATE VM, uses a higher level of abstraction and automatically minimizes error with type checking, delivering a simpler, easier, safer programming environment.
Unlike most blockchains, æternity’s core protocol was re-engineered specifically so it can accommodate state channels on a protocol level, making it easier to build applications for global-scale enterprise use cases.
æternity Oracles enable the integration of real-world data into the blockchain—a feature that has an endless range of potential use cases for business, science, and all other industries across the globe.
Miners are not the only ones who get a vote on decisions—æternity token holders can use their AE tokens to signify their vote through the Governance Aepp.
The æternity Naming System (AENS) employs safe, human-readable names in place of the current system of long hashes used in blockchain transactions, reducing room for error for users.
Having corrected the fundamental scalability flaws in earlier blockchains, the æternity protocol is engineered to accommodate large-scale enterprise use cases. æternity boasts of advanced features that connect real-world data from the Internet with the blockchain-at soft real-time.
Below are a few use cases that would be highly beneficial for most organizations:
Reference implementation written in Erlang by industry experts, the language that powers 90% of today’s world wide web. Learn more (opens new window)
State channels make it possible to execute smart contracts off-chain. The blockchain enforces the smart contract code only in the case of a disagreement between the contracting parties.
Featured in Electric Capital’s Report for being among the projects with the most committed developers per month — over 50. It is also noted that æternity has an impressive amount of dev activity ranking top 5 according to Santiment.

Sophia is a functional Smart Contract language in the ML family. It is strongly-typed and has a restricted mutable state. Sophia is a Ocaml-like language with syntax mostly resembling that of Reason.
The Sophia language was created to easily utilize the potentials of the æternity protocol. Some features of conventional languages, such as floating point arithmetics for example, are not present, while some blockchain-specific primitives, constructions, and types have been added.
