Flamingo officially launched on September 23rd with Flamincome and Wrapper. Flamincome allows users to stake wETH, USDT, wBTC, and other ERC-20 tokens to generate a yield on the Ethereum network. …


March was an eventful month for Neo, with the reveal of the N3 brand, the launch of a new neo.org website, and the release of Neo N3 RC1 TestNet.

N3 is the version brand for Neo 3.0. It allows us to market our major releases to developers, without interrupting the regular user’s relationship with Neo’s core identity. We have also started referring to 2.x (the current Neo blockchain) as Neo Legacy to clearly communicate to users that it is being superseded and will not receive further updates in the future.

Following the N3 reveal, we were overjoyed to release the…

Neo started the new year strong with the release of Preview5, a milestone achievement. As the most evolved form of Neo to date, Preview5 introduces a further simplified architecture via the new LedgerContract, and enables oracle usage for the first time through the Oracle service module.

This release contains the majority of the new functionality planned for Neo3’s final revision and will be a close match to the formal TestNet version, scheduled to launch in March. One of the last remaining major tasks, integration with NeoFS, has been a key point of development through January.

Outside of core development, Neo…


As we close the book on another year, the Neo community can look back and be proud of all that has been achieved in the last 12 months.

2020 was a year like no other. The COVID-19 pandemic forced everyone to re-imagine their personal and professional lives. Many sacrifices have been made, and new habits forged.

Neo has come through it with the help of our community and we move into 2021 with strength. Three new Neo3 Preview versions shipped in 2020, with Preview4 — the most complete and performant to date — landing in December.
