Hello everyone,

Wishing you very happy holidays!

I am Frida, Partner of Global Strategy at Sperax.

2020 is finally coming to an end. As economies plunged due to the once-in-a-generation global pandemic, the blockchain and crypto industries rocketed to new peaks. Reflecting on the year, it is proven with more and more major financial institutions adopting cryptocurrencies that the space is officially stepping into uncharted DeFi territory.

2020 was full of twists and turns for Sperax as well. The end of this year has felt busier than ever here at Sperax, and we’re looking forward to starting the new year with the same momentum. In case you missed any important announcements, here is our final newsletter of 2020.


With the Sperax Testnet going live this month, it was exciting to recently launch Sperax SMART. This experimental game allows participants to download and run Sperax nodes and earn SPA Tokens while exploring the completed Testnet on a real internet environment. If you haven’t yet, download and try out Sperax SMART for yourself!

If you have any questions regarding the set-up process, check out Joe’s user guide on Sperax testnet.

Early this December, we finished the development on all wallet functionalities and started internal testing on wallet creation, asset management, token transfer, and contact list control. By the middle of the month, Sperax Play passed all internal tests regarding wallet functionalities.

Starting from mid-December, we started developing the SPA airdrop feature, with all development finishing on December 27. This new feature is currently being tested and will be launched in Sperax Play V.1 in January 2021.

We’re happy to share that, on December 18, we submitted Sperax Play to the AppleStore for an official app review. On Christmas Eve, December 24, Sperax Play received approval from the Apple Store.

This month, we finished the development of the four main smart contracts of the Sperax Minecraft NFT Server project . These four smart contracts include: Tokens.sol for the ERC-1155 tokens, DeFi.sol for loaning the project’s fungible tokens, Governance.sol for the governance proposals of the project, and the Staking.sol contract for staking fungible tokens and minting new NFTs. We have submitted the project to Binance Smart Contract. To follow up more on this exciting project’s updates, check out the github repo.


In December, we were dedicated to going further in designing the Sperax stablecoin, sCOIN. sCOIN will be a hybrid stablecoin using cryptocurrency collateral and an algorithmically-elastic supply schedule. We studied related stablecoin design, including those of Basis, ESD, DefiDollar, Celo, NuBits and Ampleforth. We also studied the infamous NuBits failures and the Celo simulations experimental design to stress test their stablecoin.

Previous algorithmic stablecoin design is based on the Quantity Theory of Money, which controls the coin price by expanding and contracting the token supply. In our own design, we are interested in finding out the right collateral ratio and how this parameter should evolve over time. We will run simulations with top cryptocurrencies circulated in the markets and investigate their data performances in order to find the optimal solution.

We will back up the uncollateralized portion of sCOIN with an AMM algorithm. However, traditional AMMs suffer from impermanent loss, low capital efficiency, and multi-token exposure risk. We will incorporate an improved version of AMM that protects liquidity providers from impermanent loss and will design efficient incentivize mechanisms to stabilize the price.

In order to design a stable and secure staking mechanism based on token rewards, we’ve thoroughly researched the staking reward design of related Proof Of Stake (POS) protocols, including Avalanche, Nucypher, Harmony, Tezos, Cosmos, Polkadot, and more. Inflation rate is the most important factor being considered, directly related to the amount of coins in circulation and average rewards for each individual staker. Other variables, such as staking time, staking amount for each individual, and staking rate of all the coins in circulation, can also determine how the rewards will be distributed. We are working on a staking reward mechanism that is robust to manipulation, and gives strong incentive for honest nodes.

We researched how various Byzantine Fault Tolerant (BFT) protocols have participants reach consensus, and how that relates to BDLS. We also wrote a brief background for BDLS, with an overview of how it works, focusing on how it handles the famous Byzantine Generals problem in partially asynchronous networks. You can read more about it here.


We successfully launched the Sperax Ambassador Program in December. With applications coming in from all over the world, it’s exciting to welcome new members to the Sperax team. Our priority continues to be creating the best experience possible for the Sperax community — stay up to date with important updates and announcements in the Sperax Telegram channel.

To appreciate all of the SPA holders who have been patiently waiting for our official listing, we will announce our first official airdrop.

The multi-round airdrop is projected to begin in January of 2021, so be sure to watch for announcements to learn more about how to participate in this exciting and rewarding event.

Early in December, Sperax Research Lead Joe Yu made his podcast debut as he was featured on Untold Stories with Charlie Shrem. Among other topics, their conversation covered details about the Sperax consensus protocol and why it’s designed under a Type II Partially Asynchronous Network Model. The episode will air on Thursday, January 7 — be sure to check it out!

Receiving a phenomenal popularity in December, the Sperax Korean community earned the second place of real-time search in Korea’s largest blockchain community Cobak. The community has surged to over 3,200 members, who have been spontaneously retweeting and following Sperax’s events. On December 25, we held a Testnet AMA in the Sperax Korean community. The enthusiasm of the members ballooned our confidence.

Year-end summary by Frida

Looking back on 2020, I am pretty sure that it is a year that will not easily be forgotten.

On the one hand, there was immense hardship for many, while on the other hand, it was the year that both crypto and blockchain clearly demonstrated their immense potential.

The Sperax team went through some nerve-wrecking moments ourselves. The challenge of surviving in this brutal industry is what we as a small team has come to grips with and we start to manage it better.

It has been stressful, but hopeful. Here, I recap our milestones for you:

Sperax is looking at a revolutionary 2021 by altering a series of fundamental designs. These shifts will unlock the potential of a purpose-built blockchain for frictionless and accessible decentralized financial services. We will keep you updated once they are finalized.

Sharing your inquietude, we hope you understand that Sperax aims for a much longer and more ambitious picture than our peer projects; discretion is essential to a sophisticated design that can truly overperform others.

We will see you in the New Year.

With love,



Trusted Infrastructure for Decentralised Economy.
