On an early stress test on Elefos Testnet. We are excited to see our decentralized computing system can handle 5,879 transactions per second (TPS)

5879 TPS, precisely

This result shows us lots of potential improvement as we are currently running our Testnet on low-end VPS with $5–$10 per month. For more information, you can visit Elefos Monitor to see the result: monitor.elefos.io.

The highest TPS peak happen in block #50337 and #50338 (each block run in 0.5 second). The producer node is accountnum12 with is a $10/month VPS with 1vCPU and 2GB Ram. More detail:

The transaction issued is a simple transaction: “Sending token from A to B and then from B to A”.

More potential improvement:

Currently we are working on solution to boost the performance of…

We are proud to announce our second project on Elefos system — Elott — an online lottery running on the Blockchain. Elefos can support 5k+ TPS which helps Elott can handle millions of users per day.

https://elott.elefos.io

Every operation about buying ticket, drawing lucky number and rewarding winner are run and being secured on the Blockchain. Whenever you buy a ticket, you can view the transaction issued on Elefos Monitor at: https://monitor.elefos.io. Everytime the system draw the lucky number, a transaction is also issued.

In this MVP, the rule of the is simple:

  • The initial jackpot is 1000 Token.


In last October, Elefos team joined a Dapp hackathon about Blockchain, we proposed Elott (https://elott.elefos.io) and build the first prototype in 24 hours. Elott inspires to decentralized a common real-life application — the lottery and to incorporate blockchain into it to make it transparent, fair and secure. This idea can instantly be applicable to day to day life and instantly be a big hit, at the end we won the Runner Up prize in the contestElott won the second prize in the contest with $1500 prize in Ether.

Elott won the second prize in the contest which is $1500 in Ether.

From that day, the team continue to build the Elott idea, and…
