Vanity wallets usually have many leading zeros. Many advanced users use Profanity to generate attractive wallet addresses with multiple leading zeros. Profanity has a critical security vulnerability leading to complete fund loss. These users typically have an enormous amount of tokens in their wallets. A Wintermute hacked wallet 0x0000000fe6a514a32abdcdfcc076c85243de899b is
Many people are putting entire life savings in an exchange they trusted, Binance. They feel safe when some entity is responsible for guarding their funds and reimbursing them in case of unexpected fund loss. You may be one of these people. Here we will show you the risks associated with
What is data availability? Data availability in the blockchain world refers to the ability to fetch the raw data related to a particular encoded header at any time. For example, if a rollup only stores hashes of transactions, we can’t query the underlying transactions calculated into hashes. Inability to
What is Celestia? Celestia is The first modular blockchain network that provides data availability and a consensus layer. Celestia also develops some settlement layers, such as Optimint, for the developer. Combining Celestia and Optimint, only the execution layer is left for the developer to create a new blockchain. What is
We are surrounded by trees. Not normal trees but Merkle trees. These forests are very ubiquitous and are produced by virtually all blockchain network. But we know from the biology lessons that monocultures are not great for the ecology. Therefore, from totally not related reasons, the Polymer Labs are moving
Note: This blog cover cross-chain swap in the Connext testnet as of July 2022. Amarok upgrade may not be fully applied yet. In this blog, we will show the complete flow from the Connext bridge UI to the underlying transaction detail on the blockchain. To begin, you must switch your
Background of Nomad Nomad is a security-first cross-chain messaging protocol leveraging an optimistic verification mechanism to verify cross-chain transactions. The optimistic verification mechanism is battle tested. It requires a sequencer which is assumed to be honest, to keep the entire system safe. To assure that the sequencer is honest, several
What is Nomad? Nomad is a security-first cross-chain message passing protocol. Nomad focus on security rather than speed. Nomad utilizes optimistic verification, which is well battle-tested, and fundamental innovation in security. In contrast, Axelar, LayerZero, and many other cross-chain message passing protocols choose to develop their consensus, which uses external
In previous stories, we have been covering various bridging solutions. We have not assumed any prior knowledge of this subject, but we might have to spend a bit more time on the basics. Hence welcome to the first post in the series about bridging basics, where we aim to bring
In one of the previous posts, we presented a ChainBridge solution for bridging on EVM (and Substrate) compatible blockchains, which we find as an alternative to the Polymer bridging solution from the IBC and Cosmos realm. This post will stick to the EVM-compatible chains and present a new bridging solution
Today we are taking a step away from general bridging solutions and will present a solution that targets asset transfer. Without further ado, we are presenting a fresh player in the DeFi game Umee. What is Umee? Umee defines itself as a Cross Chain DeFi protocol. It is part of
In the last post, we presented the Polymer from Polymer Labs — a solution for cross-chain communication for blockchains that do not natively support the IBC protocol. But what about other solutions in this space unrelated to the Cosmos Ecosystem and IBC-sphere in general? Hence this post is where we are
Welcome to the next post in the series about Polymer, Cosmos, IBC, and general bridging technologies. Previously we presented how the IBC works. This time we are introducing the Polymer from Polymer Labs in more detail. What is Polymer, in one sentence? “Polymer Protocol enables IBC packets transfer cross chains
In the previous post on our path towards understanding birding, the Polymer, and its ecosystem, we have introduced a definition of Inter-Blockchain Communication. We now know that the IBC can stand for a standard or its implementation, enabling transferring arbitrary data between (IBC-compatible) blockchains. In this post, we will describe
Welcome to the first post in a series on building a general understanding of bridging solutions, particularly what the Polymer from Polymer Labs is bringing to the Cosmos ecosystem and beyond. In this post, we will focus on unwrapping the meaning of each of the big names from the title.
