System Challenges. On-Chain 3 Commit(s) Off-Chain Smart Contract Beyond the challenge of designing a off-chain protocol, we face other system challenges. To ensure compatibility with off-the-shelf smart contracts and to be able to benefit from the wide variety of tools for smart contract writing, testing, and verification designed by the Ethereum commu- nity, one key design goal of TinyEVM is to natively support the Ethereum Virtual Machine (EVM) bytecode. However, EVM is a 256-bit word-size virtual machine. This word- size leads to two key challenges: (1) resource inefficiency and (2) the complexity of executing 256-bit operations on a 32-bit machine. First, from a resource perspective, the EVM does not utilize the memory efficiently. All operations are based on 256-bit variables and addresses. As a result, every VM op- code, even a simple addition, operates on 256-bit variables. The main reason for this EVM specification was to ease cryptographic operations like the Keecak256, which works on 256-bit digests. However, the vast majority of variables in a smart contract rarely reach values that require 256-bit storage. Similarly, as our evaluation shows, smart contracts do not reach a size in code or data that they would need 256-bit address space. The result is an inefficient memory use that could prohibit their execution of smart contracts on IoT devices. The second challenge is the run-time overhead of the virtual machine. The embedded hardware does not directly support 256-bit operations. Instead, we have to emulate 256- bit operations using a 32-bit micro-controller by implement- ing custom libraries and, as a result, executing a single EVM opcode requires in the order of hundreds of MCU cycles. This inefficiency may further limit the potential of Ethereum smart contracts on resource-constrained IoT devices.

  • Challenges The Experts may be challenged by either Party if circumstances exist that give rise to justifiable doubts as to any of their impartiality or independence. In such circumstances the challenge shall be brought by written notice to the ICC copied to the other Party within fourteen (14) calendar days of the appointment of the relevant Expert or within fourteen (14) calendar days of the challenging Party becoming aware of the circumstances giving rise to the challenge. Unless the challenged Expert withdraws. or whichever of the Parties that has not brought the challenge agrees to the challenge, within fourteen (14) calendar days of the challenge, the ICC shall decide the challenge and, if appropriate, shall appoint a replacement Expert in accordance with the criteria set out herein.

  • Grievability Denial of a petition for reinstatement is grievable. The grievance may not be based on information other than that shared with the Employer at the time of the petition for reinstatement.

  • Non-Grievability No dispute over a claim for any benefits extended by this Health and Welfare Fund shall be subject to the grievance procedure.

  • Company Grievance It is understood that the Company may request a meeting with the Union for the purpose of presenting any complaints with respect to the conduct of the Union. If such a complaint by the Company is not settled, it may be submitted in writing as a grievance at Step 3 and may be referred to arbitration.

  • Problem Solving Employees and supervisors are encouraged to attempt to resolve on an informal basis, at the earliest opportunity, a problem that could lead to a grievance. If the matter is not resolved by informal discussion, or a problem-solving meeting does not occur, it may be settled in accordance with the grievance procedure. Unless mutually agreed between the Employer and the Union problem-solving discussions shall not extend the deadlines for filing a grievance. The Union Xxxxxxx or in their absence, the Local Union President, or Area Xxxxxxx, or Chief Xxxxxxx, either with the employee or alone, shall present to the appropriate supervisor a written request for a meeting. If the supervisor agrees to a problem- solving meeting, this meeting shall be held within fourteen (14) calendar days of receipt of the request. The supervisor, employee, Union Xxxxxxx, and up to one (1) other management person shall attempt to resolve the problem through direct and forthright communication. If another member of management is present that person will not be hearing the grievance at Step Two, should it progress to that Step. The employee, the Union Xxxxxxx or in their absence, the Local Union President, or Area Xxxxxxx, or Chief Xxxxxxx, may participate in problem-solving activities on paid time, in accordance with Article 31, Union Rights, Section 1H.

  • GRIEVANCE PROCESS RIGHTS No grievant shall lose his/her right to process his/her grievance because of Management-imposed limitations in scheduling meetings.

  • Outcome a desirable situation, condition, or circumstance in a member’s life that can be a result of the support provided by effective care management. Outcomes defined include:

  • Challenge If Executive violates or challenges the enforceability of any provisions of the Restrictive Covenants or this Release, no further payments, rights or benefits under Section 5 of the Agreement will be due to Executive (except where such provision would be prohibited by applicable law, rule or regulation).

  • Complaints Process The School shall establish and adhere to a process for resolving public complaints which shall include an opportunity for complainants to be heard. The final administrative appeal shall be heard by the School's Governing Board, except where the complaint pertains to a possible violation of any law or term under this Contract. The complaints process shall be readily accessible from the School’s website, as described in Section 11.4.1.

  • Complaints and Feedback 15.3.1 The primary responsibility for receiving feedback and investigating complaints promptly and thoroughly in respect of the Services will rest with the Provider. The Provider will have procedures in place including but not limited to a complaints framework, which are acceptable to the Department, to gather and act upon feedback and complaints from Learners and/or their representatives and employers and the wider community. The Provider must also keep a log of the complaints received which will be accessible to the Department upon request.
