Abstract

Most of today’s online services (e.g., social networks, search engines, marketplace places) are centralized, which most users recognize as unsatisfactory for various reasons (e.g., centralized governance, censorship, loss of control over personal data). Blockchain technologies promise a new Web revolution (Web 3.0) through the decentralization of online services. However, one of the fundamental limitations for this revolution to happen at a planetary scale is the poor performance of today’s permissionless blockchains. In this paper, we propose ALDER, a generic construction that multiplexes off-the-shelf permissionless blockchain protocols to address the performance bottleneck due to store-validate-forward block dissemination techniques in blockchain protocols. We apply ALDER to two representative blockchains, namely Algorand (Proof-of-Stake) and Bitcoin (Proof-of-Work), to illustrate the benefits it brings to blockchain performance. Our evaluations show that ALDER can drastically improve the throughput of blockchains when bottlenecks exist.

ALDER:通过多路共识协议解锁区块链性能

今天的大多数在线服务(例如，社交网络，搜索引擎，市场场所)都是集中的，大多数用户由于各种原因(例如，集中管理，审查，失去对个人数据的控制)而不满意。区块链技术通过在线服务的去中心化带来了一场新的网络革命(Web 3.0)。然而，这场革命在全球范围内发生的根本限制之一是当今无许可区块链的糟糕表现。在本文中，我们提出了ALDER，这是一种通用结构，可复用现成的无权限区块链协议，以解决区块链协议中存储-验证-前向块传播技术造成的性能瓶颈。我们将ALDER应用于两个具有代表性的区块链，即Algorand (Proof-of-Stake)和比特币(Proof-of-Work)，以说明它给区块链性能带来的好处。我们的评估表明，当瓶颈存在时，ALDER可以大大提高区块链的吞吐量。
