BENGALURU, India, November 25th, 2024/Chainwire/--**Kernel is thrilled to announce funding from Binance Labs, solidifying their role as a core restaking infrastructure on BNB Chain. This milestone marks a big leap in turning BNB’s economic security into programmable trust, empowering dApps, middleware, and the entire crypto ecosystem. Kernel raised 10M total funds across rounds, with the belief and backing of various investors, including: SCB Limited, Laser Digital, Bankless Ventures, Hypersphere, Cypher Capital, Draper Dragon, ArkStream Capital, DACM, HTX Ventures, Avid VC, GSR, Cluster Capital, Longhash Ventures, Via BTC, Side Door Ventures, NOIA, DWF Labs. Kernel is excited to continue building this journey and pushing the boundaries of what restaking can achieve. Building Beyond Ethereum While restaking has reshaped Ethereum, Kernel is breaking new ground by bringing this innovation to BNB Chain, unlocking decentralized, scalable trust. Backed by Binance Labs, Kernel is leading the restaking journey on BNB Chain and beyond. Kernel's Milestones Since launching, Kernel achieved: $1 Bn+ Total Value Locked (TVL) with Kelp & Gain on Ethereum
10+ Layer-2 Integrations for better scalability
120+ DeFi Integrations, fueling rapid growth
300K+ Unique Addresses, showing trust and adoption Kernel’s Visionary Ecosystem Kernel is part of a broader vision, powering the future of DeFi through three flagship products: Kernel: Cross-chain restaking powerhouse on BNB Chain, launching mainnet soon
Kelp: Liquid restaking on Ethereum with rsETH adoption skyrocketing
Gain: Tokenized yields across DeFi, CeDeFi and Real-World Assets (RWAs) Together, these solutions unlock $100B+ opportunities in across Restaking, DeFi, CeDeFi and RWAs. Introducing $KERNEL Token $KERNEL aims to unify governance and incentives across Kelp, Kernel, and Gain, rewarding early supporters and driving ecosystem growth. Kernel will first launch on BNB Chain using BNB Liquid Staking Tokens (LSTs) and restaked BNB as economic security to support DeFi innovation on BNB Chain. Plans for expansion include incorporating BTC and its derivatives as restaked economic security. Over 20 decentralized applications (dApps), including decentralized AI coprocessor, Mira, and ZK proof aggregation protocol, Electron, are going to leverage Kernel’s economic security. Several LSTs and LRTs including ListaDAO, Solv, and YieldNest, are working with Kernel to bring more utility to restaked assets. Over time, Kernel plans to expand to additional L1s, providing robust economic security and a foundation for the growth of innovative applications on Kernel. Kernel integrates native and liquid staking tokens across BNB, BTC, other yield bearing assets to improve their utility and capital efficiency. By creating a shared economic security ecosystem, Kernel enables developers to bootstrap projects more efficiently while offering users new opportunities to maximize the utility of their assets. These innovations reduce barriers for protocols and foster a developer-friendly environment, driving the growth of innovative restaking and DeFi applications.

Mobile Tracking for Low Touch Apps: Frameworks and Tips

deployments come in all shapes and sizes. We support bare metal installs on any version of , containerized installs on any version of (including Red Hat OpenShift), and installs just about anywhere you can deploy a small lightweight single binary. But with flexibility comes the inevitability that edge case issues will require debugging. MinIO Linux Kubernetes In this blog post, we’ll show you how to debug a MinIO install running in Kubernetes and also some of the common issues you might encounter when doing bare metal installation and how to rectify them. Kubernetes Debugger Pod There are a few ways to access the MinIO API running inside a Kubernetes cluster. We can use or set up a listening on to be able to access the API. Both of these methods offer a way to access the service from outside the network, but they do come with one major downside: You can only access the Service that the NodePort or Port Forwarding references on an available port (not the usual configuration for the application). For example, you have to access the MinIO API, usually found on port , via a randomly assigned port. kubectl port-forwarding Service NodePort 9000 3xxxx What if I told you there was a better way – and it's not novel? When debugging applications you want to have full access to the native run-time environment so you can use various tools to troubleshoot and debug the cluster. One way to do that is launching a “busybox” style pod and installing all the required tools needed to debug the application. First launch a into the same namespace as your MinIO install. In order to do this create a yaml file called with the following yaml. Pod debugger-pod.yaml apiVersion: v1

kind: Pod

metadata:

  name: mc

  labels:

    app: mc

spec:

  containers:

  - image: minio/mc:latest

    command:

      - "sleep"

      - "604800"

    imagePullPolicy: IfNotPresent

    name: mc

  restartPolicy: Always The above Pod configuration is pulling the image for MinIO utility. In order to ensure the pod doesn’t just launch and then exit, we’ve added a command. mc sleep Once the yaml is saved apply the configuration to the Kubernetes namespace where the MinIO cluster is running kubectl apply -f debugger-pod.yaml Once the pod is up and running access it via shell $ kubectl exec -i -t -n default mc -c mc -- sh -c "(bash || ash || sh)"

[root@mc /]# Then with you can access the MinIO cluster mc [root@mc /]# mc alias set myminio    --insecure

Added `myminio` successfully. Now that we have a debugger pod up and running, you can perform action on the cluster directly within the same network. For example, if the replication was broken due to an site going offline or a hardware failure, you can resync any pending objects to be replicated using the following command [root@mc /]# mc admin replicate resync start minio1 minio2


[root@mc /]# mc admin replicate resync status minio1 minio2

CurrObjName:  	 testbucket/web-app/tsconfig.json Another reason you would run the debugger pod is if there are some file system permissions or invalid groups configurations in your pod, you can update them using the debugger pod [root@mc /]# chgrp -R 1000780050 .minio.sys/ The above debugging method can also be used in bare metal environments. For instance you can launch a busybox or bastion node with installed and follow the same instructions as above. mc Debugging Bare Metal Bare metal Linux installs are the most straightforward. In fact it just takes a few commands to get MinIO installed and running with SystemD. For details, please see . Configuring MinIO with SystemD Once in a great while, bare metal installs go awry. Here are some of the (not-so-common) pitfalls that we are asked about  in or . These pitfalls are not hardware or operating specific but can be useful to know in any kind of environment. SUBNET Slack File Permission One of the most common pitfalls is the file permissions of the MinIO binary and the configuration file. If this occurs, when you start MinIO using SystemD you will see and here is the full stack trace Assertion failed for MinIO. # systemctl status minio.service

Dec 26 18:21:38 minio1 systemd[1]: Assertion failed for MinIO. This could be caused by a number of reasons, let's go down the list and check for each of them. : The binary, in this example located at needs to have permission for user and group, respectively. MinIO Binary /usr/local/bin/minio root:root # ll /usr/local/bin/minio

total 93804

-rwxr-xr-x 1 root    root    96018432 Nov 15 16:35  minio* : The MinIO service needs to run under a unique Linux user and group for security purposes, never run as a user. By default we use for the user and group names. In the SystemD service config file you should see something like this MinIO Service User and Group root minio-user User=minio-user

Group=minio-user : The directory where MinIO data will be stored needs to be owned by or whichever user you decide to run the MinIO service as above. MinIO Data Dir minio-user:minio-user # ls -l /mnt

total 4

drwxrwxr-x 2 minio-user minio-user 4096 Dec 27 09:58 data : Both the config files should have permissions for user and group like so SystemD and MinIO config root:root # ls -l /etc/default/minio

-rw-r--r-- 1 root root 1330 Dec 27 09:52 /etc/default/minio


# ls -l /etc/systemd/system/minio.service

-rw-r--r-- 1 root root 941 Dec 26 17:13 /etc/systemd/system/minio.service : The entire install process should be run as . You can also try if your user has permissions but the recommendation is to run as root as the install needs to place files in a bunch of places that only the user can access. Your bash prompt should have a and not a like so Run as Root root sudo root # $ vs # $ If none of the above work, the best approach is to remove the app, directories and configs and start a fresh install as a root user. Port conflict Another common issue related to deleted files which still hold on to the process, which causes port conflicts. Even when a service is not running, you may be unable to start a new service on the existing port or the service that is running will misbehave (such as not allowing you to login). # lsof -n | grep (deleted)

COMMAND PID USER FD TYPE DEVICE   SIZE 	NODE NAME

nginx   	13423 root 5u  	REG 253,3   42949672960 	17 (deleted)

minio 	13423 minio 6u    REG 253,3 	0         	      18 (deleted)

minio       13423 minio 7u    REG 253,3 	0         	      19 (deleted) You might see errors such as those below on a MinIO install Login Failed net::ERR_FAILED 500 Internal Server Error 401 Unauthorized The screenshot above shows an internal server error and an unauthorized error. While looking at the surface it looks unclear what has caused this error, we can debug with a little linux knowledge what to look for that could cause this, let's take a gander. There are several ways to debug this issue, first lets check to see if multiple MinIO processes are running on the same node # ps aux | grep -i minio

minio-u+    5048  0.3  1.7 1594008 144384 ?      Ssl  11:03   0:01 /usr/local/bin/minio server --console-address :9001 /mnt/data/disk1/minio


minio-u+    9276  0.3  1.7 1594208 144301 ?      Ssl  11:25   0:01 /usr/local/bin/minio server --console-address :9001 /mnt/data/disk1/minio As we can see above there are 2 MinIO processes running. Start by killing the process that is older or has been running the longest, in this case it seems to be the process ID . 5048 kill -9 5048 Sometimes even after killing the process the service might still not start or might still get hung up because it has reserved a process number but not let it go. This can be caused by files that have been deleted but are still being tracked by the operating system. You can find the deleted files via LSOF lsof -n | grep '(deleted)' Last but not least, if there are no deleted files left over or hung processes and if everything looks absolutely clean, the last resort is to quickly restart the node. This is a no-nonsense method that  shuts down and clears any pending files and processes so you start a fresh install. SUBNET to the rescue Although rare, installation edge cases will always exist. MinIO customers know that they have nothing to worry about because they can quickly message our engineers – who have written the code – via the portal. We've seen almost everything under the sun, so while the issue might look cryptic or mind boggling at first glance, we'll put our years of expertise debugging installations in many varied environments to work and help you in a jiffy.
