Classic PBFT Clause Samples

Classic PBFT like algorithms‌ It is interesting to see that most partially synchronous con- sensus algorithms already collect forms of cryptographic ev- idence like signatures or certificates to guarantee agreement upon decision. While this is a characteristic of PBFT [11], this is the case of modern algorithms that build upon it including Tendermint [8] and HotStuff [33]. One could naturally be tempted to reuse these signatures and certificates to piggy- back practical justifications in the existing messages of the original consensus algorithms to turn them into account- able consensus algorithms. Although threshold signatures do not convey enough information to identify which process is guilty, signatures are generally sufficient. We show below that, unfortunately, this transformation cannot work. L L The intuition of the proof is split in the four following steps while the full proof is deferred to our technical report. First, we define the class of ‘classic’ or PBFT-like consensus algo- rithms and denote it . Second, we show that HotStuff [33], PBFT [11] and Tendermint [4] belong to this class . Third, we define a practical extension of PBFT-like consensus al- gorithms that piggybacks messages. By ‘practical’ we mean that piggybacked messages have a bounded staleness to pre- vent the justification communication to be superlinear (e.g., quadratic) in 𝑛. Finally, we prove that there exist executions leading to disagreement with different sets of Byzantine pro- cesses that correct processes cannot distinguish. L L (1) Class of PBFT-like algorithms. contains algo- rithms that all rely on a leader that rotates in a round-▇▇▇▇▇ fashion across views and proposes a suggestion in its view. Two local variables per process, preparation and decision, have values that relate with each other such that for a pro- cess 𝑗 to have a decision, 𝑛 − 𝑡0 processes, including 𝑗 itself, must have had the same value as a preparation. During view changes, if 𝑡 < 𝑡0, then a preparation implies a propagation of a value to the leader within messages announcing the new view. L L −

  • CHECK-OFF OF UNION DUES The Employer will, as a condition of employment, deduct from the gross salary of each employee in the bargaining unit, whether or not the employee is a member of the Union, the amount of the regular dues payable to the Union by a member of the Union. The Employer will deduct from the gross salary of an employee who is a member of the Union any assessments levied in accordance with the Union Constitution and/or Bylaws and owing by the employee to the Union. Deductions will be made in each payroll period of each month and membership dues or payments in lieu thereof will be considered as owing in the month for which they are so deducted. All deductions will be remitted to the Union not later than 28 days after the date of deduction and the Employer will also provide a list of names of those employees from whose salaries such deductions have been made, together with the amounts deducted from each employee. Before the Employer is obliged to deduct any amount under this article, the Union must advise the Employer in writing of the amount of its regular monthly dues or assessments. The amount so advised will continue to be the amount to be deducted until changed by further written notice to the Employer by the Union. Upon receipt of such notice, such changed amount will be the amount deducted. From the date of the signing of this agreement and for its duration, no employee organization other than the Union will be permitted to have membership dues or other monies deducted by the Employer from the pay of the employees in the bargaining unit. The Employer will supply each employee, without charge, a T4 receipt for income tax purposes in the amount of the deductions paid to the Union by the employee in the previous year. Such receipts will be provided to the employee prior to March 1st of the succeeding year. An employee will, as a condition of continued employment, complete an authorization form providing for the deduction from an employee's gross monthly wages or gross salary the amount of the regular monthly dues payable to the Union by a member of the Union.
