George Kudrayvtsev demonstrates how the Composable Data Platform (CDP) and Galexie enable efficient backfilling of Stellar RPC with historical ledger data in just 12 minutes—a task that would take over an hour using traditional captive core replay. The prototype required only 80 lines of Go code and showcases CDP's flexibility for building composable ingestion pipelines.

The Stellar Development Foundation has achieved a 9x speedup in Horizon reingestion by leveraging the Composable Data Platform (CDP) with precomputed ledger metadata, reducing full history reingestion from approximately 66 days to 7 days.

The Stellar Development Foundation has launched an all-new Stellar Lab, a modernized web-based toolkit for developers to create accounts, test transactions, explore RPC methods and Horizon endpoints, and interact with the Stellar network. The redesigned interface includes mobile optimization, XDR-to-JSON conversion support, and the ability to save and share API requests.

The Stellar Development Foundation introduced Galexie, the first component of the Composable Data Platform, a lightweight application that extracts and stores Stellar ledger data in cloud-based data lakes. Galexie decouples data extraction from transformation, enabling tools like Horizon and Hubble to access precomputed transaction metadata more efficiently than relying on Captive Core.

The Stellar Development Foundation introduces the Composable Data Platform (CDP), a new open-source architecture that decentralizes data access on Stellar by breaking down monolithic tools like Horizon and Hubble into modular, configurable components. CDP enables developers to customize their data consumption patterns and infrastructure based on specific application needs.

Validation Cloud announced support for Stellar Horizon, offering high-performance Node API infrastructure with archive node data access. The service enables developers to build wallets, DEXs, and other applications on Stellar with improved performance and historical data querying capabilities.

The Stellar Development Foundation announced it will limit historical data access on its free Horizon service to one year of rolling data, effective August 1st, 2024. This change aims to reduce operational overhead and eliminate a centralized point of failure in the network, while directing users with longer historical data needs to alternative solutions like Hubble, third-party Horizon providers, or self-hosted infrastructure.

The Stellar Development Foundation announced changes to its Debian package distribution for Stellar Core and Horizon nodes. Support for Ubuntu 16.04 LTS has ended, and operators must upgrade to Ubuntu 18.04 or 20.04 LTS, with SDF committing to support all future Ubuntu LTS releases.

The Stellar Development Foundation announces Protocol 17 upgrade with a new Asset Clawback feature. Developers and node operators must update Stellar Core, Horizon, and SDKs before the June 1, 2021 network upgrade vote.

The Stellar Development Foundation executed a Protocol 16 upgrade on April 10 after an outage on April 6 caused validator and Horizon nodes to go offline. The upgrade fixed the issue affecting multiple nodes without impacting network stability.

Stellar network upgraded to Protocol 16 on April 10, 2021 following a network incident. Node operators must update to Stellar Core v16.0.0 and Horizon v2.1.0 to restore service and rejoin the network.

Stellar Development Foundation validator nodes and Horizon API went offline April 6, 2021, causing transaction processing delays and exchange withdrawal halts at Binance, Bitfinex, and Bitstamp. The network recovered within hours with SDF restoring services by April 7.

Horizon 2.0 introduces a modular architecture that decouples Horizon from Stellar Core, enabling developers to run infrastructure with significantly fewer resources, faster ingestion times, and greater flexibility. The new Captive Core approach reduces disk requirements by hundreds of gigabytes and cuts ingestion time from weeks to about a day.

A comprehensive FAQ addressing common transaction submission errors on Stellar, particularly 504 timeout errors. The article explains how dynamic fees work, surge pricing mechanics, ledger limits, and provides practical guidance for developers to optimize transaction submission and avoid timeouts.

Stellar Development Foundation released an updated analytics dataset with 5-minute refresh intervals and open-sourced its data pipeline tooling, including stellar-etl and Apache Airflow orchestration, enabling developers to build real-time Stellar data pipelines.

Stellar is skipping Protocol 14 and upgrading the public network to Protocol 15 on November 23, 2020. The change addresses a rare bug discovered during testnet testing that could have caused validator crashes. Developers running Stellar Core or Horizon must install updated versions before the upgrade.

The Stellar Development Foundation released its Q1 2020 quarterly report, highlighting progress on strategic growth pillars including Horizon API improvements, policy advocacy, marketing initiatives, and a strategic investment in DSTOQ to expand financial access in emerging markets.

Horizon 1.0, Stellar's open-source API, launches with a new ingestion engine that makes queries faster, more consistent, and less dependent on Stellar-Core. The major release includes breaking changes and new endpoints for asset trustlines, multi-sig account discovery, and network-wide offer filtering.

Stellar.org's new homepage features runnable code samples for network features like payments and asset issuance. To handle testnet resets every 3 months, the team built an automated script that checks for account existence and recreates necessary accounts, plus a function to return unused testnet lumens to Friendbot to prevent resource depletion.

Stellar has released Horizon v0.22.1 with support for Stellar-core v12.0.0 and Protocol 12. This update introduces path_payment_strict_send offers and disables the inflation mechanism. Users are urged to update their software ahead of the public network upgrade vote on October 28, 2019.

Stellar-core v12.0.0 and Horizon v0.21.0 have been released with significant protocol upgrades. The core release implements three Core Advancement Proposals including PATH_PAYMENT_STRICT_SEND, bucket list optimizations, and inflation mechanism disabling, with a validator vote scheduled for October 28th.

Stellar Development Foundation released Horizon v0.20.1 with a new ingestion system that addresses architectural issues by building a full copy of ledger state from history archives instead of relying on Stellar-Core's database. The update enables new features like "Accounts for Signers" and significantly improves path-finding performance by up to 10x.

Stellar public network Protocol 11 upgrade scheduled for June 10, 2019 at 1600 UTC. Developers must upgrade SDKs, Horizon instances, and Stellar Core to ensure compatibility.

A 2019 blog post explaining Stellar's Surge Pricing mechanism during a period of high network congestion. The post clarifies that the network is functioning as designed, describes how fees work during peak activity, and outlines SDF's scaling efforts.
