eCash

<p>Today, July 1st, we are celebrating eCash Day, marking five years since the eCash rebrand and a milestone in the ongoing mission to deliver peer-to-peer electronic cash at global scale.</p>
<p>Since the last eCash Day, a defining development was the activation of Avalanche Pre-Consensus in November 2025. It introduced ~2-second instant transaction finality on a Proof-of-Work blockchain for the first time. This meaningfully improved the user experience, allowing payments to confirm almost instantly while preserving decentralized security.</p>
<p>Alongside this, the ecosystem continued to expand across stablecoins, real-world asset tokenization, developer infrastructure, wallets, and application-layer growth. Together, these developments are shaping eCash into a more complete financial system, combining strong base-layer performance with increasingly practical applications.</p>
<p>From protocol upgrades to real-world integrations, this period reflects continued progress toward a system designed for everyday use.</p>
<p>Let’s look at the key milestones that defined this period in the eCash journey.</p>

<p>On November 15, 2025, at block height 923,347, the <a href="https://e.cash/blog/preconsensus-launch" rel="noopener noreferrer nofollow">eCash network officially activated Avalanche Pre-Consensus</a>, delivering instant transaction finality and real-time consensus on a Proof-of-Work blockchain for the first time ever. This upgrade marks a major milestone for eCash and brings its vision of fast, secure, and user-friendly digital cash closer to reality.</p>

<p>Also launched on November 15, 2025, Staking Rewards Pre-Consensus enables eCash staking nodes to use Avalanche polling to come to consensus on the staking reward winner for the next block&nbsp;before it is mined. This improves predictability, coordination, and efficiency for the staking process.</p>

<p><img src="https://academy-public.coinmarketcap.com/optimized-uploads/0e9daf4764f9406e9563ed0a49fac699.jpeg"></p>
<p>On November 15, 2025, 64-bit integer support went live, unlocking billions of times more precision for both sat and token values. Agora swaps can now price assets exactly, enabling truly accurate markets and more advanced financial use cases on eCash.</p>

<h3 id="strong-chronik-support-for-the-electrumx-protocol-strong"><strong>Chronik Support for the ElectrumX Protocol</strong></h3>
<p><img src="https://academy-public.coinmarketcap.com/optimized-uploads/77895190c5cb40758d6090c74ffa0f9e.jpeg"></p>
<p>On July 10, 2025, with the release of Bitcoin ABC v0.31.8, Chronik became fully compatible with the ElectrumX protocol. This makes it easy for existing BTC and BCH applications using Electrum servers (such as Fulcrum) to add eCash support or migrate to Chronik seamlessly.</p>
<h3 id="strong-themay-15-2026ecash-network-upgrade-strong"><strong>The&nbsp;May 15, 2026&nbsp;eCash Network Upgrade</strong></h3>
<p><img src="https://strapi.e.cash/uploads/May_2026_fe0aae0bb3.jpg"></p>
<p>The planned May 15, 2026 upgrade of the eCash network was successfully completed, marking a coordinated protocol transition across the ecosystem. The first post-upgrade block was block 949,200.</p>
<p>This upgrade consolidated a series of performance and scalability improvements across the node software stack. While versions 0.33.x and later include enhancements to Avalanche Pre-Consensus and the mining layer designed to support significantly higher transaction throughput during periods of peak network activity, these specific optimizations were not activated as part of the upgrade itself. Instead, the mandatory upgrade process ensured that all nodes had the updated implementations deployed and ready ahead of activation.</p>
<h2 id="strong-electronic-cash-conference-2025-strong"><strong>Electronic Cash Conference 2025</strong></h2>
<p>On October 4–5, 2025, the Electronic Cash Conference (ECC 2025) was held in Spain, bringing together developers, researchers, and builders from across the electronic cash ecosystem.</p>
<p>During the conference, eCash founder Amaury Séchet officially announced Avalanche Pre-Consensus, publicly unveiling a milestone years in the making. The announcement outlined how eCash would achieve instant finality and real-time consensus on a Proof-of-Work blockchain, setting the stage for the mainnet activation that followed on November 15, 2025.</p>
