DOGE New tiers, not new currencies
Fintech company Metallicus has launched an Alpha version of DogecoinVM. This is a new payment layer that can increase the transaction speed of Dogecoin ($DOGE) on the main network by 300 times. Marshall Hayner, CEO of Metallicus and a member of the Dogecoin Foundation's board of directors, described the breakthrough as a technical response to the challenge Elon Musk posed to the Dogecoin community in 2019. At the time, Musk believed that to become a practical global payment system, Dogecoin needed to significantly increase transaction throughput.
Metallicus did not modify the Dogecoin Core protocol, but instead developed a separate parallel layer-Dogecoin VM based on the Metal Blockchain infrastructure. Hayner emphasized that the system will not introduce a separate cryptocurrency or change Dogecoin Core. Dogecoin VM is fully compatible with Dogecoin's UTXO model, allowing users to continue using existing wallets and private keys.
Working principles and limitations
DogecoinVM achieves speed improvements by replacing Dogecoin's energy-intensive Proof-of-Work mechanism with Snowman's Proof-of-Stake consensus mechanism. According to Metallicus, transaction confirmation times are approximately 0.15 to 0.25 seconds, and throughput is no longer limited by strict block size limits that affect the underlying network.
该机制如同一个双向桥梁：原始 DOGE 在主网上被锁定，而在 DogecoinVM 内部则按 1:1 的比例发行抵押支持的等价代币，并可随时提取。目前处于 Alpha 测试阶段，每笔交易的存款上限为 100 DOGE，且系统尚未通过独立的安全审计。
Hayner 表示，更广泛的目标是实现金融科技、银行、信用合作社及平台等领域的实际应用，强调了将快速加密货币结算整合到包括社交网络 X 在内的支付服务中的长期潜力。
