Internal optimization of mainnet and cross-chain code completed;

Security audit of mainnet, cross-chain code and software wallets by Knownsec was completed on March 21, 2019;

CertiK has successfully completed the security audit for Waltonchain, a leading blockchain project leveraging RFID technology, on September 18, 2019;

77 community members invited for mainnet & cross-chain partial open source testing.

Fully Operational Waltonchain Mainnet released

Waltonchain Mainnet was officially launched on March 31, 2018. After stable mining and operation for more than a year, and the successfully audit by Knownsec, as part of the preparation period for the upcoming mainnet token swap, the Waltonchain Team has released the Fully Operational Waltonchain Mainnet on April 24, 2019.

Public Mining on the Fully Operational Waltonchain Mainnet

Since its release on April 24, 2019, operation of the Fully Operational Waltonchain Mainnet has been stable; and public mining officially started at block #40,000. Waltonchain community miners can start mining with the updated version of WTC Wallet and browse the updated blockchain explorer.

Completion of WTCT Network Miner Payout

According to the Announcement on the Release of the Fully Operational Waltonchain Mainnet, Waltonchain Team took a snapshot of WTCT addresses at block #550,000 on May 11, 2019.

Waltonchain team has already completed the miner payout for ALL unredeemed WTCT up to block #550,000 at the ratio of 1 mined WTCT : 1 ERC20 WTC. Waltonchain team will no longer perform miner payouts for WTCT mined after block #550,000. Please access your ERC20 WTC according to the instructions in the announcement.

Waltonchain Mainnet Open Source

Following the release of Fully Operational Waltonchain Mainnet and the start of public mining, we officially announced the open source of Waltonchain mainnet. Waltonchain makes its source code public aiming to provide a more open development environment for community users and developers, attract global quality developers to optimize the mainnet functionality, bring a new digital life and realize the Value Internet of Things.

Mainnet Upgrade on June 18, 2019 (block height 149,500):

A new version of X11 ordering algorithm based on the locked block height algorithm uses fixed seed data to calculate X11 order so as to prevent cheating and realize fair mining.

Mainnet Upgrade on June 29, 2019 (block height 175,366):

· Updated PoS algorithm as below. Mining difficulty will decrease along with the increase of WTC balance in the mining address.

· Fixed malicious CoinAge exploit.

· Cancelled the WTC balance requirement for creating smart contracts.

Mainnet Upgrade on July 17, 2019 (block height 221,500):

· optimized mainnet data transmission to support higher child chain throughput; improved data transmission reliability to meet the demands of the ecosystem with numerous child chains;

· adjusted the average mainnet block generation rate to stay within 30 ± 0.5 s.

DMTC Airdrop

In recognition of the support from the Waltonchain’s global community, Walton Chain Foundation launched an airdrop of 1,700,000 DMTC (equivalent to USD 100,000) to users who hold 5,000+ WTC.


As an important part of the Waltonchain ecosystem, Waltonchain’s KIRINPOOL was officially launched on June 11, 2019.

Fee Exemption for SMN, GMN and MN:

In return for the long support from the global Waltonchain community, starting from early July 2019, KIRINPOOL will exempt SMN, GMN and MN users from pool fees. Fee for normal users remains 3%.

Waltonchain Launched SMN Cross-chain Data Management System

As an important part of the Waltonchain ecosystem, Super Master Nodes (SMN) undertake the important responsibility of cross-chain data connection and endorsement. The parent chain operation has been stable; and its source code is now public, therefore Waltonchain officially releases the SMN Cross-chain Data Management System. The existing data on blockchain is the core logistics data of Huodull which are being uploaded continuously.

Announcement on Waltonchain Mining Payout

While Waltonchain prepares for token swap, in order to ensure the timely reception of miner rewards on mainnet, shorten the ROI period and reduce mining risk, Walton Chain Foundation started ERC-20 token payout in exchange for the WTC mined by individual miners (outside KirinPool) at 1:1 ratio each Friday in Q3.

Token Swap

WTC mainnet token swap started on October 15, 2019. Exchange platforms OKEX & TAIBI and Ellipal software and hardware wallets supported mainnet WTC coins in 2019.

Huodull Child Chain

Existing data on blockchain is the core logistics information of Huodull. The main task of Huodull is to track logistics information through blockchain and obtain endorsement on the parent chain. With the launch of SMN Cross-chain Data Management System, core data of Huodull is being continuously and regularly endorsed on blockchain.
