Recently, a whitehat hacker pwningpwnwpnw reported a vulnerability in smartbchd. The vulnerability is located in MoeingEVM’s `host_bridge`. It is a bug in the C++ implementation of SEP206. The overflow condition of `amount+margin` was not checked. This is a severe vulnerability which allows an attacker to mint infinite BCH on the…

The CoinFLEX’s restructuring proposal will be voted on very soon. After reviewing the documents provided by CoinFLEX and consulting with our lawyers, SmartBCH Alliance decides to support this scheme of the arrangement upon certain conditions which have been verbally agreed by CoinFLEX. …

In the past few weeks, while under tremendous pressure, we have been working on the decentralized bridge, SHA-GATE v2 and the draft specification has been released. (https://bitcoincashresearch.org/t/the-draft-specification-of-sha-gate-v2/862). We released SHA-Gate2 CashScript covenants for reviewing. (https://github.com/smartbch/cc-covenant). We also released SmartBCH v0.4.5 (https://github.com/smartbch/smartbch/releases/tag/v0.4.5).

Dear smartBCH users: As you have already known, the smartBCH community is in an urgent situation. The centralized bridge maintained by CoinFLEX is stuck now. And the native token on smartBCH, which will be referred to as “sBCH”, is not 1:1 anchored to BCH on the main chain. As a decentralized bridge…

Since first proposing the SHA-Gate’s scheme, nine months have since passed. The native introspection opcodes have enhanced BCH’s scripting capability, and, in the process, we have learned a lot in practice. It has now come to the time we should revise its scheme and improve upon it. SHA-Gate means “Smart-Holder-Authorized…

In our early article introducing cloud enclaves, a mechanism for building manipulation-proof random number generators (RNG) with SGX enclaves was presented. …

Even as a DEFI beginner, you may already find SEP20 token’s approving transactions are annoying: if you want to add liquidity to the CATS/FLEXUSD pool, you must send one transaction for approving CATS and another transaction for approving FLEXUSD, before you can finally deposit your CATS and FLEXUSD tokens into…

We are proud to introduce the first ahead-of-time compiler for EVM: moeingaot. In the smartBCH’s whitepaper, we wrote: “EVM, which is adopted more commonly than other VMs like WebAssembly, is a de facto standard for smart contracts. However, EVM lacks certain important speedup methods, such as ahead-of-time (AOT) compilers and…

After the XHedge hard fork was applied to the Amber testnet on 14 Feb 2022, it has been working smoothly for seven weeks. Now we are going to apply the XHedge hard fork to smartBCH’s mainnet at the height of 4106000 (next Wednesday, 20 Apr 2022). The name “XHedge” of…
