This week, Feng Han was on the road again, introducing Elastos while speaking about the digitalization of wealth at the Central Party School in Haidan District, Beijing and the BCHC Global Consensus Conference in Macau. Elastos made significant development progress in completing Phase 4 of its six-phase DPoS Consensus implementation module . Finally, we will be adjusting our publication schedule here on the Elastos blog to enrich our content delivery. There’s a ton to catch up on in this week’s report.

– Going forward, the Elastos Report will shift to a biweekly publication schedule. A biweekly schedule will allow our media team to more effectively collect relevant news and updates and produce richer content in our Elastos Reports. We look forward to providing a valuable resource to help our community remain connected and informed about Elastos and its development.

– The Elastos Foundation is pleased to announce that Phase 4 of our six-phase DPoS implementation module is now complete. The Elastos blockchain has been updated with the latest code to support a fully integrated DPoS consensus. In order to adopt the most recent infrastructural upgrade, miners should update their ELA client at the earliest convenience.
