Data in NeoFS is stored on storage nodes that are distributed across the globe. Everyone can be a part of NeoFS storage network the same way as anyone can be a part of N3 network by deploying its node.

Economic model of NeoFS provides two sources of income for storage nodes: basic income and data audit payments. Basic income settlements happen once in epoch for all available objects in storage nodes based on global basic income rate controlled by the committee. Data audit is triggered if data owner creates special storage group objects in the container and they are paid…

When we showed you our hilarious cat available via HTTP gateway a month ago, the gateway wasn’t open-source yet. We took some time to work out the kinks and finally released it to the public right at the end of April. Now you can enjoy it yourself — run it either as a part of a backend system for your dApp smart contract (maybe even N3 hackathon smart contract), asset storage for a traditional web application, or just for fun.


The gateway lives on GitHub and you can grab the latest release in a standard way (single binary). …


In our previous article, we learned how to start using NeoFS in the N3 RC1 testnet. We created our first wallet, made a deposit, and even managed to upload a cat. Want to get it back via your browser? Or let other users obtain such a cutie?

Now, for public containers, you can get access to this picture (or any other object uploaded) using HTTP. We have already deployed several NeoFS HTTP Protocol Gateways as a tech demo for you to start. In our next articles, we are going to tell you how to deploy your own NeoFS HTTP Protocol…

This article is a new episode of a multi-part series to get familiar with NeoFS and its features. Today we will look at N3 oracles and how NeoFS objects may be accessed from smart contracts. This article consists of two parts. The first part describes oracle concepts and NeoFS integration. The latter part is an enhanced example of NeoFS N3 oracle usage for dApp.

N3 Oracle

Blockchain cannot obtain information from the external network, and Oracle solves this problem. As a gateway for smart contracts to communicate with the outside world, Oracle opens a window to the outside world for blockchain. …

Following the recent launch of the N3 TestNet, we are excited to announce an updated NeoFS test environment deployment. All users are invited to test out NeoFS and experience its features.

In this initial stage, we have deployed NeoFS on the N3 TestNet so that anyone can take advantage of storing objects on real distributed NeoFS network instances. Simply upload your objects and then access them anywhere through the NeoFS CLI or N3 smart contracts, powered by oracles.

To make it simple for non-developers, we also launched our updated HTTP gateway for anyone. …


This is the next article about the comparison of architectural features of NeoFS with other decentralized storage systems. The first overview of existing decentralized storage solutions can be found in the NeoNewsToday article about services such as NeoFS, Sia, Swarm, and Filecoin.

The comparison with Filecoin is also available in the article and the Neo Live talk about distributed cloud storage platforms with AMA session. Today we will look at Storj, which is the closest to NeoFS in terms of the ideology of building services and integration with other protocols, like AWS S3, and etc., …

NSPCC continues tracking Neo 3 development and benchmarking node implementations. Previously we’ve benchmarked preview3 nodes and showcased some post-preview3 improvements made to NeoGo, but now we have proper preview4 releases for both implementations, and it’s interesting to see what has changed there.

neo-bench updates

As usual, we’re using neo-bench to test nodes, and as usual, it has improved since our last post. There were some internal improvements like configuration templating and the ability to build C# node from source code, a number of minor bug fixes, but one change stands out significantly: transaction-pushing code was reworked to handle congested mempools correctly.



With the development of decentralized services and the launch of new solutions in the field of distributed data storage, more and more attention is focused on this topic. The first overview of existing decentralized storage solutions can be found in the previous article by NeoNewsToday about services such as NeoFS, StorJ, Sia, and FileCoin. In this review, we want to focus on comparing NeoFS and Filecoin.

NeoFS is a distributed, decentralized object storage network developed by Neo SPCC. NeoFS Nodes are organized in a peer-to-peer network that takes care of storing and distributing user’s data. Any Neo user may participate…

The figure of 10K TPS has been long known as theoretically possible for Neo, but claiming to know kung fu is not the same as showing it. That’s why after the Neo 3 preview3-compatible release of NeoGo 0.91.0 in August and some associated performance measurements we’ve asked ourselves — can we do better than that and how far away that 10K TPS is? NeoGo had never been truly optimized for TPS before (we had a lot of other things to do), so we started looking into ways to improve it and now we have something to show.

Testing setup

We’re constantly improving…


Time flies fast and a number of important things have happened since our previous post on benchmarking. Neo project went through v3.0.0-preview2 and v3.0.0-preview3 versions of Neo node followed by compatible 0.90.0 and 0.91.0 versions of NeoGo. With NeoGo 0.90.0 release we started making neo-bench compatible with Neo 3 versions of both C# and Golang nodes and testing preview2-compatible nodes. Preview3 and 0.91.0, however, emerged so quickly that we hadn’t managed to publish those results. At the same time, we now have something to share for preview3 which is much more relevant, so dive in.

Testing setup and methods

We’re using the same single-node…
